Appeal for the People of Christchurch City

2011-02-25T16:41:00.000-08:00

At 12.51 pm on Tuesday, 22 February, the beautiful city of Christchurch, New Zealand, was devastated by a magnitude 6.3 earthquake.

This was only one of the hundreds of aftershocks, following the magnitude 7.1 earthquake that shook the city on the morning of Saturday 4 September 2010.

Miraculously, few people were injured in this huge shake for the city was asleep when it struck and despite its magnitude, its centre was 30 to 40 km west of the city centre. Christchurch was well on the way to recovering from this earlier devastation when the second major shake struck on Tuesday at a depth of only 5km.

Tuesday’s shake caused devastation that reduced many of the homes and buildings in the inner city to rubble. Over 120 people so far are known to have died, crushed by falling debris or within collapsing buildings. Over 200 people are listed as missing. Hundreds are injured, many of them severely.

The people of Christchurch have a strong spirit and they have a fine mayor in Bob Parke r, whose civil defence leadership skills are second to none. But the people of Christchurch need you.

The Value of Instruction

2010-12-04T17:57:00.000-08:00

“A long time ago, in Newsday for November 15, 1994, Billy Tashman said with reference to a large, government-sponsored field test of different instructional approaches: ‘The good news is that after 26 years, nearly a billion dollars, and mountains of data, we now know which are the most effective instructional tools. The bad news is that the education world couldn’t care less.’
The same holds true today." James Kauffman

When I first began teaching, I bristled with the desire to instruct, inspire, coach, and enlighten. I’d just been through Moray House College of Education, Edinburgh, where my tutors and mentors truly recognised the worth of excellent instruction.

Yet for the past 30 years and more, I have felt like a disillusioned school teacher who is old fashioned, out of date and not really understanding what’s happening in education.

The other day, a good friend and colleague passed on to me a recent article from Teachers College Record, by James Kauffman. It was written as an introduction to his recently published book,

The Tragicomedy of Public Education:
Laughing and Crying Thinking and Fixing.

As I read through Kauffman's article, I recalled how I felt when I read Shelley Gare’s book,

The Triumph of the Airheads and the Retreat from Common Sense.

I experienced déjà vu at every page.

James Kauffman is Professor Emeritus of Education at the University of Virginia in Charlottesville.

In his review article, entitled Reforming Public Education: A Tragicomedy, he explains how some people, working within education, fail to recognise the most important factor in improving learning:

“Truly ridiculous statements about reforming schools have been made by generally intelligent people who happen to botch thinking about education. Too often, their silly statements are taken seriously, making matters worse. Some would-be reformers ignore what produces most learning — instruction.”

Kauffman draws attention to all the areas of stupidity in education that I’ve complained about, for decades . . .

. . . about improving teaching:

“They might say we need better teachers without defining “better.” People aren’t necessarily better teachers because they’re smarter, know their subject better, or have taken more courses. We need standardized tests, but good teaching isn’t easily measured as “value added.” “Better teacher” doesn’t necessarily mean “higher average pupil gain score.” Good instruction is defined by what a teacher does.”

. . . about pursuing change without recognising what needs to change:

“On January 2, 2010, Kevin Huffman published in The Washington Post his heartfelt opinions about how to reform education, including suggestions that we recruit talented teachers and fire bad ones, base policies on student achievement, and get parents to demand what’s best for their children. He quotes a U.S. Senator from Colorado, who says that the education system must change, but he doesn’t say how. Any change will do? Sorry, Kevin and Senator, with all due respect, we don’t need just any kind of change. Unless it’s the right change, we’ll get nowhere.”

. . . about the misunderstanding and misuse of statistics:

“One reason the “thinking” of so many earnest reformers is tragicomic when it’s taken seriously is that you can’t have all of the children (or teachers or any other group we measure) reaching any percentile higher than the first group any more than you can have all of the children (or teachers) above average.”

. . . about setting education goals that are absurdly unachievable:

“No Child Left Behind (. . .) set the goal of universal proficiency of students by 2014. That goal is a will-o’-the-wisp that anyone else who understands the most basic mathematical-statistical realities knows is impossible.”

. . . about teaching methods inappropriately applied to all learners:

“Direct, systematic instruction is more effective than other approaches like “discovery learning” (essentially, letting kids find out for themselves) and a lot of the other popular but failed ideas about teaching. Go to www.adihome.org/ to find out more.”

. . . about using test scores to judge success.

Kauffman lists his criteria for judging success:

effective instruction,
students’ engagement in productive activity,
homogeneous grouping for instruction,
positive emotional climate,
clear school-wide expectations,
positive support for desired behaviour,
involvement of parents and communities.

Nor Any Drop To Drink - BLOG ACTION DAY 2010

2010-10-16T04:14:00.000-07:00

A rare commodity

Water is amazing. It is truly the universal solvent. While there are solvents that can dissolve some things far better, there is none that dissolves as many different substances as can water.

It’s all to do with the structure of water’s molecule – that particle scientists refer to when they talk of the tiny bits that some things are made of. Water molecules can cluster together and share parts of each other to form other discrete particles that have unique affinities for different things.

Sugar is made of molecules. Common salt consists of two very different bits, called ions that are positively and negatively charged.

Though sugar and salt look very similar, their fundamental differences, at the sub-microscopic level, make these substances behave so very differently. Very few solvents can dissolve both sugar AND salt for this reason. But water can.

This strange property of water – the ability to dissolve molecular substances as well as those that are made up of ions – is one reason why it is extremely difficult to obtain pure water.

When it rains, droplets of almost 100% pure water form high in the atmosphere. Yet it’s not long before this water has dissolved all sorts of substances, often before it reaches the ground. Pure water is actually an extremely rare substance.

Repositories for everything

Near-pure droplets of rainwater that drench the land eventually find their way into the oceans. There is a little bit of everything to be found in the world’s oceans. This is because water dissolves just about everything.

Gold is one of the world’s rarest and most precious metals. Yet we are told that the world’s oceans contain enough dissolved gold to provide every person with a tiny piece weighing over 8 tonnes!

Gold is just one of the billions of substances that water washes into the world’s oceans, every day. The seas and oceans throughout the world are repositories for all that is washed off the land.

End to fresh water

All over the world, beautiful freshwater lakes represent a half-way house for water that makes its way to the sea. These wonderful reservoirs are topped up by rivers and streams fed by water that takes many paths, from slow percolations of ground water to direct runoffs.

Fresh water reservoirs contain water that has had only a relatively short time in contact with the earth. Most contain water that is near pure. They have enjoyed a place in the eye of the beholder for thousands, perhaps millions of years. Lakes, and the streams and rivers that contribute to them, have served living creatures with necessary fresh water during that time. But this service is literally drying up.

Something in the water

Supplies of drinkable water are dependent on readily available fresh water sources. The demand for water of this purity is increasing every day. I’m told that about 24 litres of fresh water can be used during the entire production of just one hamburger. Yet the world’s fresh water supplies provide water only at a worldly rate.

That rate is huge, and hitherto has been unvarying. While that rate is now not sufficient to provide the world’s demand for fresh water, there is much now happening on the surface of the earth to actually decrease the rate of this provision.

Wastes from farming, industry and the effluent from the people who rely on these present day processes are fast diminishing the usefulness of water sources. Many fresh water reservoirs are now becoming polluted and the level of pollution and the occurrence of this are always increasing.

Now running to ground

About 20% of the world’s fresh water is drawn directly from the ground. It is seen as a way of safeguarding against periods of drought while providing an almost unvarying year-long supply of fresh water – water that slowly percolated its way through the ground. Such water sources are still vulnerable to pollution, however, as surface pollutants can percolate through the ground and contaminate the ground water.

Moreover, the removal of ground water at a rate higher than the natural recharge rate means that these sources diminish in time and can affect water replenishment of nearby reservoirs.

A global contribution

Further to this, some people who support theories of global warming believe that the usage of ground water may actually contribute to global warming, a proposed climatic effect that may also contribute to diminishing the supply of available ground water.

The world’s use of fresh water is now outstripping the rate of its supply. And there are factors brought about through industrialisation and land use that are serving to reduce the suitability of otherwise useable fresh water.

Clearly the world’s populations cannot continue to consume water the way they have been up till now – and it will take more than just a token act of water conservation.

AADES LEADERS' FORUM 2010

2010-10-12T21:37:00.000-07:00

AUSTRALASIAN ASSOCIATION OF DISTANCE EDUCATION SCHOOLS
29 September - 1 October

Venues: Te Kura (Day 1) and Te Papa Museum of New Zealand (Days 2 and 3)
Wellington, New Zealand

SUMMARY:

I was privileged to attend the AADES Leaders' Forum 2010.

This was a well attended three day event, with speakers from New Zealand and afar. While I attended all three days of the Forum,
I did not attend every session and there were some that were held concurrently. However, I report on all the keynote speeches here.

This was essentially a listeners’ event, though there was a little opportunity for participation from the floor.

Day One consisted of a late afternoon powhiri held at Te Kura.

Marcus Akuhata-Brown was the facilitator for Days Two and Three of the Forum, at Museum of New Zealand Te Papa Tongarewa. His humility, balanced approach and sense of humour were evident in the elegant way he conducted the programme.

A feature of the Forum was the Māori music and harmony. Each guest speaker was thanked in a traditional way by music and song, a true mark of respect. It is a credit to Mike Hollings that he joined in with every one of those musical occasions (I’m sure he engineered them all) most times accompanying on his guitar. This part was altogether a most memorable, entertaining and cultural contribution to the atmosphere of the Forum.

DAY ONE

The Forum began mid-afternoon with the gathering of staff, contributors and visitors and a powhiri in Kauri room, Te Kura, followed by congenial time for refreshment.

Then followed brief welcoming addresses from Mike Hollings, Trish McKelvey and the Chair of ADDES, Bronwyn Stubbs, as well as short speeches from Karen Sewell and Janelle Cameron.

Karen Sewell

Karen spoke of the future that lay in the education of children. She spoke of the trauma that children suffered during and after the recent Christchurch earthquake, and how Te Kura had stepped in extremely quickly to provide support with this.

She talked of the complex and uncertain future that children will follow. Education must transform, not reform ‘the system’ in order to permit children to navigate intricate pathways. Teachers have a part to play in changing our children’s future.

Janelle Cameron

Janelle spoke of the digital divide – how she was still grappling with the technologies – how the digital age seems to overwhelm many people of her age.

Her metaphor for the happenings in learning today was like “a train going through (a station) and not stopping”.

She referred to the Internet and its use as a teaching tool and to what she called “Bloom’s Pedagogy”, the new “Digital Taxonomy” and their part in teaching today.

Day One closed with drinks and nibbles and a chance to network.

DAY TWO

Hekia Parata

Hekia gave us a National Party view of where teachers are at in 2010. She spoke of them focussing “on teaching rather than learning”
(I think she was referring to their learning rather than the learning of their students). Hekia explained that teachers do not seem to learn from learning, and referenced this to education research.

She referred to the mind/brain as the most important part of the being. Yet kids, all over the world, are still sitting in classrooms being taught by a single teacher using traditional teaching methods.

Hekia specially referred to the 1 in 5 students that were clearly being failed by the system – that schools focussed on crowd control rather than on learning.

Hekia’s description of Ruatoria formed a large part of the manifesto-like speech she delivered. She spoke of her family/ brothers, sisters/ community and what they did when she was a child.

Hekia spoke of the demography of New Zealand and of how many children were uninspired at school.

She spoke of the money New Zealand borrows every year to spend on education and the community. Hekia referred to the 1 in 5 ratio and that for many, the model is not working. Her concern was mainly about what she called “brown students”, and referred to their place in the diverse population that is evolving in New Zealand.

She spoke of professionalism that customises skills to give a service, and that such a service was needed by the 1 in 5 children in New Zealand: those that needed to find a job, for instance – a sector that “deserved all the attention teachers can give”.

Hekia summarised her speech by referring to the triangle of Identity, Community and Education: three important areas that provide the basis for learning in an individual.

Liz McKinley

Liz examined some of the statistics on Māori success in education from the Starpath project, University of Auckland. Her quote from Niels Bohr, “Nothing exists until it is measured”, summarised her approach.

She also examined some recent government statistics of Level 2 NCEA results, from 2003 to 2008, comparing Māori with non-Māori. Only 40% of Māori learners get to year 13. Less than half of these go on to study at tertiary level. She showed graphs indicating that in percentage achievement and in success rate, Māori learners were substantially behind learners from other ethnic groups.

Liz analysed these results in a number of ways: that 32% of Māori learners in a year 13 group will eventually go on to further study – that 18% of those will have achieved university entrance qualification – that 6% will actually enter university – that 2% will finish the courses with a degree – that 0.4% will go on to doctorate study.

She explained that Starpath, led by The University of Auckland in partnership with the New Zealand Government, is a research project (now in its 6th year) that focuses on the educational outcomes of New Zealand learners who under-achieve at secondary school. Starpath utilises:

research teams,
5 high schools,
1 university and 1 technical institute.

Liz spoke of the need for evidential material that schools require in order to make informed decisions – that schools were not getting help with bringing all available useful data/ideas/strategies together and with aligning these so that they could be used to improve learner outcomes.

She explained that schools do collect data on student learning and achievement, but the data is not centrally stored. She asserted that schools do not feel that ownership of this data is important. She stressed that there was a real need for concerted strategies so schools could usefully collate data related to student achievement and use this to accomplish an improvement in learner achievement.

Liz spoke of the Academic Counselling and the Target Setting (ACTS) programme and how they improved final year NCEA completions. The biggest gains were made by Māori and Pasifika students, with 16% more Māori students and 20% more Pasifika students achieving important learning in NCEA Level 1 Numeracy and Literacy.

Liz concluded by warning that gains for Māori learners were lessening - that many schools had a plethora of programmes, 84 in some, based on teacher interest rather than what could benefit the learner. She appealed that this was actually a moral issue that needed attention, by all parties including teachers in order that it be addressed effectively.

Bentham Ohia

Bentham, CEO of Te Wānanga o Aotearoa, gave an overview of the Open Wānanga – a “Māori Higher Learning Tertiary Institution” of 37,000 learners – 40% of those do not have a secondary education.

He put a number of questions:

What counts as knowledge? What knowledge counts? Who decides?
What counts as success? What success counts? Who decides?
What counts as assessment? What assessment counts? Who decides?”

Te Wānanga o Aotearoa is unique:

kaupapa wānanga
unique programme-offering delivery
home based kaitiaki (guardian) supported
monthly cohort enrolments
centralised support
minimised restrictions.

Viv White

Viv spoke briefly of Big Picture Education Australia (BPEA). She then looked at some learner statistics and other related learner information:

14% learners not learning or earning – 50% in some places
20% fail to complete year 12 – 50% in some places
complex social background
distance education is not immune to the same problems that exist in F2F systems.

She stressed how serious these facts were and that a new model was called for. Viv then put the question that I had asked her at TCS Forum in May this year(!) – basically:

“Can we create a Big Picture Distance Education model?”

Viv then returned to the Big Picture model:

1 learner at a time (which is how Te Kura works)
small by design
advisory 1 – 15 | 1- 17 |
Learning Training Internship.

Learners could achieve improved outcomes: engagement – graduation – tertiary learning. She spoke of beginning with network connections – developing a community of practice and commitment to collaborate – building a system of influence: not with critical mass but with critical connections (BPEA and Te Kura).

Jen McCutcheon

Jen defined authentic learning in the context of Te Kura, explained the process and outlined some of the approach used – one that focussed on the learner in context. She spoke of how it relies on rich conversation between the Learning Advisor, the learner and whanau.

Jen explained how finding the centre of what interests and impassions a learner was an all important part of that process. It’s then that a start can be made on building relevant programmes around the learner and nurture these with frequent ongoing discussions.

Jen went on to define what constituted a ‘rich conversation’: goal setting – identifying ‘aspirational’ goals – career exploration – interviews and talking with people – job-shadowing – resetting goals. She mentioned the part that Gateway, Star and other programmes can play in the development of this process.

She described the ‘tail of underachievement’ and mentioned the consequential 25% of people aged 15 to 19 years who are unemployed.

Westley Field

Westley is Director of Online Learning, Skoolaborate. He began his delivery by demonstrating an online delivery/facilitation by an avatar in Second Life (SL). Westley then Skyped his friend, Chris, who was the person behind the SL avatar.

Westley spoke briefly of the developments in online learning at MLC School. He spoke of how technology makes the routes to achievement more facile, and not just in learning but also in creating commercially useful objects, such as the Doritos commercial he showed us and that was made for $150 by a teenager using readily available equipment.

He encouraged that we should “try things new” – to “move forward with real action”. He spoke about personalised (online) learning. He spoke of how to get the attention of learners if they have computers in their hands. He spoke of how “knowledge”, and how to use it, takes on a new meaning with the developments in technology, Google and the Internet.

Westley talked about giving people experience in the use of technology – in particular giving young learners safe, ‘unblocked’ experience in technology use. He spoke of the technologies that can change learning, including the development of the e-book such as the Amazon Kindle.

He referred to the improved success by learners using online learning productively with other learning methods compared to those learners who are in the classroom without such technology.

Sandy Dougherty & Nathaniel Louwrens

Sandy and Nathaniel gave a presentation on their experiences in trialling Active Worlds. The study was to evaluate Active Worlds as a learning technology and also its suitability in a distance education setting.

They demonstrated a treasure hunt that had been built in the 3D environment of Active Worlds. Some of what they reported was about their own initial experiences in the 3D environment – some of the seeming ‘chaos’ perceived by people who are new to this technology – which later developed to a successful resolution.

Their intended focus was to be on working with learners collaboratively and how to get learners to work together. The reality was slightly different.

Sandy and Nathaniel found that young learners (years 7 to 10) learnt the technology skills for themselves very quickly, skills that the teachers had taken 2 terms to learn. They also reported that the learners preferred online (txt) chat rather than using the voice chat, though they were comfortable with the teacher using voice chat in instruction.

Sandy was careful to get useful (and fascinating) feedback from her learning group, to which she put a number of questions. Asked how they learnt, Sandy’s students gave a number of interesting answers, among which were ‘playing’ and ‘practicing’.

Asked if they needed a teacher there was met with a resounding, “YES”. The children preferred the teacher speaking to them rather than using the chat box. The common feeling expressed by learners was that the whole learning experience was “awesome!”

About the technology . . . learners felt that though it was a bit clunky, it was like playing a game that was really school. Navigation in commercial games technologies tend to be far more facile in comparison and the 3D renditions are often superior to what they experienced in Active Worlds.

DAY THREE

Mike Hollings – Walking in Two Worlds

Mike spoke of the money poured into education and the efforts that are not actually achieving learning. He cited Cisco’s The Learning Society and stressed that the cost of education should be tax-efficient.

A successful education system has to be based on the principle that it is for everyone and must embrace ones personal culture while at the same time supporting innovation. He stressed that there was a need for a huge change in present systems. He cited Phillippe de Woot’s need for societal educational metamorphosis and referred, once again, to Allen Curnow’s Landfall into Unknown Seas:

“Simply by sailing in a new direction
You could enlarge the world.”

Mike spoke of leadership today and the huge diversity of theories that are based largely on western ideas. He asked of leadership, “what could we learn from other wisdom?”

He drew attention to how Māori people spend a lot of time ‘going back’ to their cultural places, communities and the related pursuits. The educational system in New Zealand does not acknowledge this cultural aspect as much as it does that of western cultures in activities such as music, opera, and dance.

Mike gave an overview of some of the wisdom from Māori leadership, and how it focussed on the needs of people and the resources they needed – the understanding of communities and their tribal/cultural boundaries. Māori leadership qualities are not necessarily accepted or respected in the wider community in New Zealand. Mike listed some of the elements of that leadership:

Manākitanga – hospitality
Rangitiratanga – weaving people together
Whanaungatanga – interdependence
Wairuatanga – spirituality
Kaitiakitanga – guardianship
Whakapapa – genealogical connections
Te Reo Rangatira – Māori language

Mike observed that community intellect is at risk when languages are lost. He also spoke of the worth of trust and the value of openness – that for trust to exist, intentions must be clearly understood and patently visible.

Mike summarised the thrust of his speech by saying “we cannot (always) rely on western systems”. He referred to the importance of locality in determining who we are and where we are at in New Zealand. He used lines from the poem Lost, by David Wagoner, to illustrate this:

Lost

Stand still. The trees ahead and bushes beside you
Are not lost. Wherever you are is called Here,
And you must treat it as a powerful stranger,
Must ask permission to know it and be known.
The forest breathes. Listen. It answers,
I have made this place around you,
If you leave it you may come back again, saying Here.
No two trees are the same to Raven.
No two branches are the same to Wren.
If what a tree or a bush does is lost on you,
You are surely lost. Stand still. The forest knows
Where you are. You must let it find you.

Jen McCutcheon and Viv White

This was a panel session introduced by Marcus Brown where Jen and Viv spoke freely of their vision of the Big Picture.

Jen gave a brief summary of the Big Picture process including some of the best practice used. There then followed a brief session of questions from Marcus and from the floor. Jen and Viv both spoke to the questions that were asked.

Brenda Frisk

Brenda summarised her vision of what she called “visual knowledge” and its place in 2010. She spoke of the need to reduce the barriers that may exist between people and their use of available technology, and also of the need that industry has to learn to manage technology. She posited that teenagers lose trust and respect for people in industry when they see that they do not have skills to use the technology effectively.

Brenda spoke of tacit knowledge, implicit knowledge and cultural knowledge and their use to the people employed in a company. She emphasised the need to have online portals for children to access at any time of the day.

She spoke of the frustrations that an organisation has in finding and in accessing data with technology and that there was a need to have technology built for people, not just for the technologists to use. Its property and function need to be relevant, evidential, contextual, credible and collaborative.

Brenda spoke of two important reports, the Horizon Report and Learning Powered by Technology, and summarised some of the key elements brought out in these. She then spoke further on visual knowledge and explained and demonstrated how 3D (stereoscopic) visualisation could give a better perspective in viewing machines and other structures in context.

Hine Waitere

Hine introduced herself from her tribal background, then spoke of ako, a pedagogical concept that encompasses both teaching and learning as parts of the same process. She illustrated how ako had been brought out in the Forum with reference to those presenters who had told of their experiences in learning (and teaching) during their presentations, and the stories they told.

She spoke of Māori carvings and tukutuku and how these also have stories to tell. They are different forms of literacies. Hine spoke of her appreciation of landscape but also recognised that there was much there she did not understand.

Hine read the story, Butterflies, by Patricia Grace, depicting ‘difference’ without a need for that difference to be fixed. She went to the heart of this idea by referring to how the grandfather did not correct the teacher, but simply explained where she was at.

She also illustrated how teachers have power and authority to direct ‘values’. She asked,

“What are the values that lie at the core of our (teaching) practice?”

She then talked about the tail of young learners who struggle with their ‘education’, listing the 5 Ds:

Deficit
Deprivation
Disadvantage
Difference
Diversity.

Learning, Literacy and Learner Skill

2010-09-14T17:43:00.000-07:00

This year, the New Zealand Ministry of Education displayed a list of terms in a draft instruction sheet for learners of Chemistry.

The proposal is that page 3, labelled for student use, may assist learners to reach the standard and achieve a rudimentary qualification in secondary education (NCEA Level 1).

Learners at this level must have a “comprehensive understanding” of aspects of basic Science. Here’s a sentence from the draft sheet:

A comprehensive understanding means you are able to link ideas to integrate the relevant chemistry through elaborating, justifying, relating, evaluating, comparing and contrasting, or analysing.

The new Bloom’s Taxonomy, a tool for teachers, lists the same and similar terms as in the sentence shown above. It is understood, however, that teachers using Bloom’s taxonomy are either familiar with the meanings of the terms or have the initiative and required education to find out about these for themselves.

Terms like justifying and evaluating are not easy to define clearly, even for some teachers. Most teachers do not draw a clear distinction between the processing skills of contrasting and comparing, say.

Yet these are just a few of the difficult terms that are found in a draft instruction to NCEA Level 1 learners.

As teachers, of course, we must teach/coach/train our learners to be able to recognise the difference between such terms as contrasting and comparing. The learner needs to be introduced to what each of these analysis processes has to offer.

Why do we end up asking kids to get their head round the lingo that teachers may well have difficulty grappling with? I wonder if this intellectuality is really beyond the stage that most NCEA Level 1 learners are at, given that many already have difficulty with literacy at this level.

It seems that responsibility for learning continues to devolve.

It is as if learners are now expected to know the meaning of terms (or at least acknowledge their existence) often before they have the chance to get any real practice in the skills they are the labels for. These are skills that learners may not yet have the developmental ability to permit them to understand.

An Apology To Stephen Hawking

2010-08-11T19:52:00.000-07:00

In April 2009 I wrote a futuristic verse. It was a contribution to meet
Bud the Teacher’s deal to write a poem a day for the whole of that month. The verse looked only a little way into our possible future.

In the last stanza I predicted that Stephen Hawking might never have had a chance to say what I assumed had been running through his mind.

“It’s been a long time since Cataclysm.
They said in the beginning it might be
quite a journey. And so we are all here
in one form or another. No one knew
it would be so simple to start it off.

Even Fermi didn’t, though more than most
he had the insight. ‘So where are they all?’
was what he put to them, knowing full well!

Fermi? He’s over by the supernova.
Can’t get him away from it. Addicted
they say – he always was fanatical.
Apparently he was among the first
to congratulate Hawking when he got here.

Hawking knew all along of course. It was
only a matter of time. And before
he let it all out it was far too late.”

I may have been wrong about Stephen's timeliness. I hope I was.
If so, I offer him my sincerest apology.

Let’s hope that Stephen’s advice is timely, to assist us to survive so our successors can tell a different tale a few hundred years from now.

Where Has Education Gone?

2010-05-28T22:42:00.000-07:00

The Skill Mastery Hyperdome - SLENZ Project - Foundation Studies Build, Kowhai

Authentic learning is a solution to some of the problems
that arise in schools, workplaces and in society today.

Isn’t it funny that at a time when training is being heaved out of the workplace by a change of organisational thinking, it must find in-roads to secondary schools where, purportedly, it is desperately needed?

Last week, I attended the Te Aho o Te Kura Pounamu All-School Forum 2010. This was an international occasion for Te Kura.

Three Keynote speakers - Viv White from Australia, Elliot Washor from the United States and Stuart Middleton from New Zealand - gave their perspectives on ‘authentic learning’ in schools.

Stuart could not attend the Forum. He gave a recorded presentation outlining how he saw the history of what has happened globally to education in the past 50 or so years, and how those changes are impacting on what is happening to the youth in society today.

ROSLA

Clearly, the raising of the school leaving age, by several years, has brought about changes in how education is delivered. It has also altered how society looks on school-leavers who go about looking for jobs.

A number of associated changes have accompanied all this.
The origins and reasons for the changes are complex. But the situations for prospective employment of school-leavers are implicit.

Over 40 years ago it was acceptable for kids to leave school without having any formal qualification. There were plenty of jobs for them. They were trained and educated on-the-job, and stories of their successes in life are numerous. Education through ‘the university of life’ was not an uncommon occurrence. As well, night classes became very popular. These provided a useful adjunct to the education of that group of learners.

But the gradual societal changes, brought about through the raising of the school-leaving age and the programs introduced to schools to cope with these, meant that jobs for inexperienced and unqualified youths became less and less plentiful. What’s more, the general calibre of those jobs is now of a lowly nature and night classes are disappearing.

Hands on

Today there is a desperate need for kids who are likely to leave school early to be introduced to vocational possibilities during their remaining school years. It’s being recognised that preparation for the workplace in a hands-on manner and while kids are still attending school, is an effective way to accomplish this.

It so happens that the standards-based qualifications system adopted in New Zealand early this century was adapted from the trades schemes. Argue as you may, there is more training taking place in schools today than was delivered there 40 years ago.

It’s now recognised that the vocational access routes available for learners in schools are still not enough, a situation which is driving ‘authentic learning’ schemes into schools. I agree that more of this is now needed. I just wonder at what society is doing to education.

Knowing what to do

Education is supposed to be preparation for life. It has been said by many educators that “education is knowing what to do when you don’t know what to do”. When schools become geared to providing training for kids so that they can step into a job as soon as they leave school, isn’t there a possibility that ‘preparation for life’ will have to be diminished and/or postponed? When does that start if it has been displaced by the need for more immediate training in schools?

Journey

2010-05-10T20:10:00.000-07:00

As teacher, I often tramp the journey. Most of the way, I learn more than I teach, which is fortunate as I’m bored easily.

Even the well trodden-paths bear fruit. But I have to be more aware when pacing there; vigilant, else I miss what is to be learnt.

As teacher, most of what I learn on the well-tramped lanes happens as I watch others less familiar with the paths. This learning is the most enlightening, yet so difficult to pass on to others.

I’ve begun to understand why.

As teacher, all learning is a journey. How can a learner explain the destinations to someone who has never been there and seen what they’re like? There is often no measure to compare, no gradation to gauge against, and no foundation to build upon.

And so learning, once accumulated, is not necessarily always useful. At least, not as useful as we might think it should be. And so it is that the adage of teachers ‘filling jugs’ doesn’t really work, no more than their teaching does.

Johnstone’s Information Processing Model, a simplified version which heads this post, suggests that there is a real need to tread the ways often. It implies that learners may not be wholly aware of what’s to be learnt on the way, nor of its significance even if they were.

It also reinforces that perhaps filling jugs doesn’t work so smoothly, that much is spilt in the process – that many approaches may have to be tried before the jugs contain anything useful at all.

The Tale Shouldn't Wag The Dog

2010-05-07T17:34:00.000-07:00

I finished writing a print-based learning resource a few weeks ago. I say finished – it was really only a draft before I passed it on to the editors.

I put a copy of it on the Science database and was grateful for feedback received from our now huge Science teaching cohort. It was good to get comment from colleagues who, like me, had been plunged into the sweat of writing learning resources to deadlines.

Storyline an interest

Among many aspects of the draft discussed was its storyline. This attracted interest from my colleagues as it was seen as an effective teaching feature. It also made me think more deeply about strategies I’d used in creating the storyline in the first place. I realised that I hadn’t really planned it.

It became clear with more thought and discussion that a storyline in a learning resource should not be a starting point for writing. My past experience has shown me that building necessary learning around a plot can be difficult. It’s a manufactured process that has the potential to limit severely pathways the writing may follow.

A different approach

Adhering to a storyline can stymie other useful teaching ideas that may otherwise emerge. It can lead to contrived resource components that do not satisfactorily contribute to effective learning.

The storyline that seemed to work so well in this resource was created using an entirely different approach. Here’s how it came together for a NCEA Level 1 generic learning resource on writing a scientific report.

Staid and boring stuff

I started on the second chapter simply because it was the one I had in mind when I put my fingers to the keypad. My plan was for Peter to write a report of something he did during his holidays and hand it in for his Science teacher to assess at the start of term.

I had practically finished that chapter when I'd already decided that it was boring, principally because it involved doing homework for a teacher. Undaunted, I continued with chapter 3, then drafted chapter 1 and was half way through chapter 4 when I really couldn’t pursue my ideas any more. The resource was becoming all too staid and boring.

Change tactics

I went back to chapter 2, stripped it down and rewrote it introducing a friend, Mahi, an intelligent Māori girl who could write good scientific reports.

It was she, not the teacher, who read Peter’s brief report of his visit to a museum exhibition on colossal squid. It was she, not the teacher, who desperately wanted to see the exhibition after reading Peter’s report.

And it was she who tried to follow the deficient instructions in the report. As a result of these shortcomings, Mahi missed out on her planned visit to the exhibition – all good material to use for teaching about informative report writing.

I switched back to rewrite parts of chapter 1, simply introducing the characters Peter and Mahi. I then flicked to the other draft chapters incorporating the growing relationship between Peter and Mahi as friends who supported each other with their interest in Science.

Here’s how chapter 1 begins:

Reading magazines

Peter found a magazine page that had an article about a car that ran on water instead of petrol.

Activity 1A

Read Peter’s magazine page shown below.

1 What is the name of the magazine that this page came from?
__________________________________________________________________

2 Explain two things you see on the magazine page that might suggest that the information about the car is not true.
__________________________________________________________________
__________________________________________________________________
__________________________________________________________________

Peter wanted to find out more about the car, so he went to a car showroom and spoke with a salesman. The salesman laughed at Peter and did not believe that a car like that could be made. Peter still wasn’t sure if the information in the magazine was true.

3 Explain two other things Peter might do to find out if the story in the magazine is true.
__________________________________________________________________

Proof of the pudding

The rest of the resource fell into place using the theme of collaborative learning between two school chums. Peter followed up Mahi’s library research into giant squids and colossal squids. He then asked her for help when drawing a graph for the report he was writing.

Instead of Peter handing in his report for a teacher to mark, he chose Mahi to help him improve it. This permitted a chummy dialogue between two friends that was not only fitting and appropriate, but had the potential to enhance learner interest.

All this was laid over a framework of teaching and learning. I got a real kick out of how easy it was to incorporate a story line in a learning resource, and from the supportive feedback I received from colleagues.

The proof of the pudding will be when I examine feedback from learners!

What Are Teachers For?

2010-04-29T19:32:00.000-07:00

I have heard it said that teachers are assessors and that assessment is part of the teaching and learning process. I often wonder if the meaning of the word ‘assessment’ is sometimes stretched and perhaps misused in contexts to do with learning.

Standard assessment

At the moment, NCEA standards are of two types. There are Unit Standards, awarded to learners who meet all component criteria for a particular standard. There are also Achievement Standards, awarded as Achieved (just a pass), Merit and Excellence.

Re-assessment

A learner, who does not meet the criteria for a unit standard or for an award in an achievement standard, can choose to be re-assessed after a period of re-teaching and further study.

My thinking has never been aligned with the philosophy of teaching to a standard. I don’t believe that’s what ‘education’ is about. However, as a teacher, I have no choice but to accept the assessment system that is now intimately bound with secondary education in New Zealand.

At least re-assessment permits the learner to revisit the learning and allows the teacher to do some more teaching.

Re-submission

NZQA is reviewing, again, the process of assessing learners for NCEA standards in New Zealand. The specific issue that I bring to this post is the matter of what’s called a re-submission. I’ll explain.

When a learner completes and submits a standard assessment test, and it is not clear to the assessor whether the learner has actually met the standard, the test script can be returned to the learner for amendments to be made. These are performed by the learner under test conditions before re-submitting the test script for the assessment to proceed. This process is called re-submission.

Furthermore, during re-submission the learner is not permitted to study on the topic, nor receive any teaching, coaching or advice associated with the standard, before revisiting assessment tasks they performed in the test script. They are only permitted to consider their answers and perhaps amend them.

There have been many debates by teachers about what constitutes a case for re-submission. Performing a re-submission is quite different from entering into a phase of re-teaching followed by re-assessment. Teachers like things to be cut and dry. So many discussions at the moment centre on the criteria for re-submission.

A disservice to learning

As a teacher who is more interested in what learners learn and how they learn, than what they achieve in a standard test, I am often in a bind over the issue of re-submission.

I feel that I’m doing learning a disservice if I do not permit (and cannot permit) learners to revisit the learning. This is precisely what happens, and must happen according to the rules for standard assessment, when re-submissions are permitted for learners who are very close to meeting criteria for a particular standard.

In such instances, I start wondering what my role is as a teacher and educator. I also wonder if I am doing learners a disservice by permitting them to re-submit their test evidence without any further teaching and learning taking place.

I feel that if learners are in need of more teaching and learning, then they should be given the opportunity to receive just that. This opportunity is denied learners who gain a standard on re-submission.

What are teachers for?

Day In The Extreme

2010-04-25T13:49:00.000-07:00

What a wonderful cornucopia of extremes in a day! I am delighted to report a baker’s dozen of contributors and their extreme creations:

Cheryl enjoyed . . .

I spent the day shivering in a snowy storm, skiing trails that went from powdery snow in fog, to cream cheese snowy views across the valley where there was sun.

Gail Poulin busied . . .

I spent a busy day with my husband as we worked like soldier ants lowering stumps, covering the area in wood chips, transplanting bushes, and finally relaxing peacefully on the deck with a beverage and watching nesting birds at the feeders.

Virginia completed . . .

I started the day with an empty calendar for the month of May and now every day is filled with at least one thing and many times two.

Mr Wood experienced . . .

The day began cold and grey, then became hot and sticky, and just after it got wet and sticky, it became sunny and warm.

Kabod facilitated . . .

I delicately discussed "Stirrings" in The Giver over and over today with silly, pubescent Seventh-and-three-quarters Graders.

Ken waxed . . .

In 24 hours, our bathroom was transformed from a functional facility and possible retreat to an empty wooden box with holes in all sides that the wind whistled through.

Anonymous sighed . . .

Yesterday morning I got to play with my granddaughter in the morning and had to kiss her good by in the evening. I wouldn't get a chance to see her in person again till June.

Gail Desler expressed . . .

I spent the day with 6 dedicated, innovative, caring 5th grade teachers, 5 of whom received "pink slips" this month (where in the heck did the expression "pink slip" come from - and what's the terminology in your district?). Difficult times in California.

Bonnie extemporised . . .

Could there be anything more extreme? We left on a plane from Tel Aviv, Israel on Monday night at midnight and arrived at Newark airport, New Jersey at 5AM and there's a 7 hour time difference. So getting back to normal, well what's normal anyway?

Elona announced . . .

My students were working away quietly at the begining of the class and then the fire alarm went off.

Tracy activated . . .

A flurry of activity to get parent permission for 25 students in 15 minutes for a last-minute opportunity to attend a day-long literary festival, after which I stayed at the school in the quiet of my classroom for the day :)

Kevin initiated . . .

Between coaching youth baseball, writing a grant proposal, composing daily poetry, working on some educational pieces for a website and watching my three boys run-run-run, the week of school vacation has been anything other than restful.

Cynthia ebulliated . . .

The air was already oppressively humid at 7:15 a.m., and then the rain began; however, the seniors were able to have their crawfish boil at 1:00. Yum!

Extremes In A Sentence

2010-04-21T01:08:00.000-07:00

Yes. I know. It's been over a month now. I have been immersed in resource development and other things - overseeing bathroom and kitchen refurbishments at home, while catching up with my family who have been on leave recently.

This week I am, once again, privileged to be hosting Kevin's Day In A Sentence. Kevin Hodgson (aka Dogtrax) has kindly let me host this week's DIAS.

Just to put you in the picture, Kevin is an energetic, community minded teacher who is forever creating new ideas to involve people in people activities. One of his most successful ventures in this direction is his weekly Day In A Sentence. People are invited to summarise in one sentence a day out of their week.

There's been a lot in the news lately about Earth's, now famous, gastronomic eruption in Iceland, Eyjafjallajökull. This amazing phenomenon stirred again most recently, a clash of the Earth's hottest and coldest elements, to bring about a truly global effect.

This week's theme for Day In A Sentence is to summarise in one sentence the extremes of your day. So sock it to us, hot and cold, wet and dry, happy and sad, whatever . . .

. . . just give it all to us in a sentence by clicking here, or by leaving your sentence in a comment at the foot of this post.

Authentic Elearning?

2010-03-09T01:56:00.001-08:00

When a learner is in an environment that is relevant to what's being learnt, the likelihood for effective engagement is high. Learning by doing is supposed to be one of the most successful ways to learn.

Both these factors – the relevant environment and the doing – are thought to provide jointly the greatest incentive for a learner to take interest in what is to be learnt. They form the basis for what is referred to as authentic learning.

For as difficult as such situations are to establish and sustain in face-to-face situations, elearning environments can present major barriers to authentic learning that are almost impossible to overcome unless the elearning vehicles are in situ.

Typical examples of these are online tutors for word processing, graphics applications or other computer functions where the learner is involved in using mouse and keyboard to operate a tutorial directly relevant to the application.

I cite the Southern Hemisphere planisphere with a built-in tutorial as one example of an in situ learning vehicle in a junior Science elearning resource.

The examples given above are all very well, but unless a considerable component of what is learnt is transferable to other purposes, the learning acquired by the learner has limited use elsewhere. One of the characteristics of authentic learning is the transferability of the learning to other situations or disciplines.

Two examples where generic and transferable skills can be learnt are online instruction in touch-typing, and the use of a flight simulator as part of training to become an aircraft pilot.

Kallan and Tuxedo presenting a session in building in SL

Recently I was privileged to share in the facilitation of a session sponsored by ISTE, teaching people online to manipulate and assemble prims, the building blocks of Second Life (SL).

As well, part of the duties I perform as an ISTE docent in SL involves assisting and teaching newcomers to that environment by the use of text and voice chat. The learning facilitated in these situations is authentic.

People who come into SL need to acquire new skills. Most who stay to use that environment want to learn skills that can only be acquired online. But other than exercising skills in associated disciplines such as art and design, the skills I teach to newcomers are only useful in Second Life. And here is the conundrum associated with authentic elearning.

Apart from learning that is directly associated with the elearning application or platform, how is authentic learning achieved online?

A Hierarchy of Learning

2010-03-03T13:43:00.001-08:00

My work environment has been a bit noisy lately. The school is having the roof renovated. The building’s air-conditioning units have been disconnected during the time of this refurbishment.

It being summer, there’s a need to open windows and to bring in industrial air-conditioning units to maintain a workable atmosphere within the building. At the beginning of this week, contractors wheeled two of these units into the space close to my office area, plugged them into the mains and switched them on.

Other units were similarly introduced at points throughout the building. The Science teachers who worked in the areas, including myself, viewed this activity with amusement. It was evident that the contractors knew nothing about thermodynamics.

It sucks

The heat exchange part of an air-conditioning unit operates in a way similar to a refrigerator. In normal use, the unit sucks warm air from the room through a cooling unit and filter. Fresh air from outside the building is drawn in through windows and other openings to replace the heated air expelled during the process.

The resulting chilled air is blown back into the room while the removed heat is air-pumped to the exterior, usually through a duct in a window.

In the case of the units that we observed, there was no such venting. Instead, the hot air from the action of the cooling unit was being pumped back into the room. It was as if a fridge had been turned on and its door had been left wide open. In such a circumstance, the fridge does nothing more than make a noise and heat the room.

The overall effect of the air-conditioning units being used in this way was not unlike that of using large blow heaters. In no time, people started to complain about the rising temperature.

A little learning

Science is a wonderful thing. Its principles are being utilised in just about every piece of technology that contributes to our lives today. Of course, an understanding of scientific principles isn’t always necessary to use or install the equipment that puts these principles into effect.

There are at least three levels of understanding that can allow one to realise the significance of a scientific idea, such as the thermodynamic principles that were put to use in the construction of the air-conditioning units:

It works provided certain conditions are met according to a recipe for installation. For the air-conditioning unit to be effective, it has to be functioning and have its required vents clear, one of which has to be ducted to the exterior.
It works as it follows the thermodynamic idea that heat can be pumped by using a small amount of energy that is eventually released as heat (which is why the fridge with its door open does nothing more than heat up the room).
It works, and its function can be explained by thermodynamic principles:

a) energy can neither be created nor destroyed,

b) heat energy is released when a gas is compressed so that it condenses to a liquid and this same heat is taken in when the liquid is allowed to evaporate – this is what happens in the heat exchange unit of a fridge,

c) some energy will always be wasted when heat energy is pumped using mechanical means – entropy is always increased as a consequence.

Understanding at level 3 can be achieved by senior secondary school Physics students.

Level 2 can be understood by able students of Junior Science.

Working recipes that define the factors that are important in level 1 need only be followed when it comes to the correct and appropriate installation of a piece of technology in general circumstances.

The example that I unpack here shows how related learning can apply at various levels to the curriculum. What is significant is that the most elementary levels of learning are still important to the correct use of technologies that involve sophisticated principles in their design and construction.

Sorted

As it happens, the contractors were notified by Science teachers about the correct use of the air-conditioning units which were immediately switched off. Appropriate locations near windows were then found. Necessary ducts to the outside of the building were fitted correctly to the machines within 24 hours.

Through all this, the cicadas continued their sibilant summer chorus.

Progression, Proficiency and the Expert

2010-02-28T23:05:00.001-08:00

This week I was introduced to the beta version of an elearning application I thought I was familiar with and that I’d been using for the past 6 months. I’ve seen one minor upgrade in that time.

Beta is one of the stages of development in software release cycles when the application is made freely available to users, well before the general release date. This practice allows software developers to gather general feedback on design layout and functionality. It also assists with the detection and monitoring of otherwise unknown faults.

I prided myself on my competence in using the generally available interface (not the beta). I thought I was at least as capable using it as I am in using many other applications on my PC. But I felt like a newbie when I attempted to use the beta release, even when I appreciated that there were evident improvements compared to the accustomed version.

This scenario is not uncommon. I often find that my apparent expertise on a computer disappears. And it’s not failing memory either. It can happen overnight when a new application version is installed or a so-called upgrade is made.

Give and take

I concede there has to be a balance between the need for a more attractive interface to impress new users who may otherwise be put off with what may appear to be a less attractive interface, and the necessity for regular users, familiar with features and layout of an application, to be able to utilise the new environment with relative ease.

But experienced users have the knowledge of functionality and feature. Though they may not know where to find these on the latest version of an interface, they will know to look for them. I feel grateful when I have this knowledge.

When I go looking for a feature or function, the prior knowledge that such a feature or function exists in the old version spurs me on to keep looking for it. I always hope that it hasn’t been listed with other, perhaps unrelated options or features to do with a different functionality.

What's given

Take the introduction of Word 2007, for instance. My expertise with a word processing application literally became virtual when I began working with Word 2007. It took me several weeks of use before I felt reasonably comfortable using the menus on the new release.

Even now, there are some functions I know must exist in that application that I can’t find – even using the help menus. How do I know they exist? From my knowledge of feature and functionality my experienced use of past Word versions has given me, of course.

What’s more, I had to find out that the Word 2007 default .docx files that could then be created on my PC were unlikely to be readable by others when I sent them as attachments. So a whole functionality, new to me and many of my colleagues, had to be sidestepped in order to achieve necessary connectivity, despite that functionality being given in the default file type.

It’s one of the vagaries of change. Despite the best intentions, things will evolve that aren’t necessarily helpful or useful.

What's taken

In future, the watchword is concept not know-how. The future expert is one who can take forward the conceptual framework of ideas, features and functionality and look for their equivalents in new circumstances.

The successful future machine, application or interface is one that can mirror these ideas, features and functionality in a way that permits them to be found intuitively by the expert.

Computer Reality

2010-02-19T18:09:00.001-08:00

Typists who could rattle out a notice on a Remington Portable knew nothing of word wrap. So-called word processors simulated part of the procedure of carriage return by using ‘Return’ keys, now replaced by ‘Enter’ keys on the QWERTY keyboard.

I worked in an office when bound, printed instruction manuals were in their heyday. I didn’t need to read a manual to find out that it was useless either. I could tell from its crisp pages and gleaming cover.

The contents of useful manuals fell at my feet when I took them from the shelf. Company experts on procedures were usually those who wrote, added to, or amended manuals like these.

Many things we now do in the workplace, and the way we go about them, have arisen through the inclusion of the computer. Much of those were modified and re-jigged, or even scrapped from practiced routines and procedures and reinvented, when the use of computer technology became a mandatory part of the processes.

Dissemination of procedural instructions

One of the artefacts that almost disappeared through all this was the printed process specification or business procedure manual. It was sometimes replaced by an online version – less convenient in some ways, more facile in others.

One argument in favour of this replacement was that updates to procedures could be conveyed instantly to a network of workers. In the past these changes were scribbled on the margins of printed manuals and referred to until new versions were published.

But if there is no rigorous and timely procedure for updating an online manual, the user can’t scribble notes in the margins when instructions drift out of date. That is unless they print their own version at some stage. Many do, for this and a number of other reasons. In doing this, however, they may lose touch with subsequent amendments that are only announced on the online version.

Sometimes the business procedure manual, if it existed at all, simply disappears altogether, to be recreated in notes and copies of those made by industrious workers who recognise the need for a manual of some sort. Announcements of new procedures or changes to existing ones sent round by email are filed in either digital or printed form by this diligence.

Evolving 'expertise'

Through this process there evolves a wealth of expertise of varying quality. Someone in need of information about a business procedure may skip around a workplace looking for advice from those workers well known for gathering and squirreling away procedural information.

And new ‘experts’ come into being.

This is all very well, until there is a real need for a unified approach to a specific and important procedure. It is a property of communities that exists in large workplaces, that they are recursively elaborate and capricious in how each separate part functions according to its situation.

So what's the solution to communicating unequivocal up-to-date procedural methods of practice to all parts of the workplace?

Using Elearning Resources and All That Gear

2010-02-17T21:45:00.001-08:00

The Particle Laboratory, Teal

This week I submitted my plans for three Science learning resources that I will be writing this year. The expectation is that the drafts will have an online component.

I say drafts, for when the resources are built and accessible to the learner, the intention is to amend and refine them, as part of an ongoing process, dependent on analysed feedback from the learner.

Each resource set will provide teaching and learning material for a learner to achieve an associated NCEA Level 1 Science standard.

There will be no formal question-and-answer written tests for these.
All of them include reporting of a sort – a way that learners can show their communication skills – as well as demonstrating their knowledge and understanding of the various aspects of Level 1 Science.

Learning and assessment

I was heartened by Britt Watwood’s response to my last post on elearning and pedagogy.

He kindly included a link to the Virginia Commonwealth University Online Teaching and Learning Resources Guide, which I read. It was a joy to see the inclusion of the terms formative assessment and summative assessment, with appropriate links given so that their use is unequivocal.

Summative assessment will take the form of teacher assessment, driven according to assessment schemes written against the NCEA Level 1 Science standards. But the formative assessment that has to occur before that will consist of an assortment of methods including:

self-marked booklet study

computer assessed interactive activities

teacher feedback

creating and maintaining learner engagement.

For those who are unfamiliar with the term, formative assessment is a means used by a learner to reflect on what’s been learnt and understood. A course of action may be followed to do further learning if required.

Formative assessment can involve a teacher who provides feedback to the learner. It takes the form of automatic computer feedback in interactive elearning resources. Or it can be a checklist of answers or explained processes to supplementary examples given in a printed resource book.

A rudimentary example of formative assessment is a list of answers to clues in a crossword puzzle.

Down to Earth

One of the standards involves investigating an astronomical or Earth science event. When writing my draft resource for this standard, I will be pulling on all appropriate techniques in elearning that are available to me and my cohort of learners:

keeping a balanced approach to what is e-offered to the student

keeping in mind the fundamental principles of creating and maintaining elearning engagement

elearning pedagogy (Oops! Did I really use that description?)

use of existing resources appropriate to the teaching, such as the learning resource on drawing scientific graphs – this resource provides computer created formative feedback

use of existing internet resources such as the wealth of specific webcam portals – these resources can be incorporated as a series of possible internet links

use of possible internet resources filtered through the use of specific, teacher created criterion focused internet searches.

I will keep in mind the usefulness of games-based learning and will try to remember all that’s considered to be elearning myth.

Elearning? Pedagogy?

2010-02-11T23:54:00.001-08:00

Southern Georgia teaching an intermediate session to ISTE members in Second Life

Isn’t it strange that we read, hear, and see a lot about elearning, but we so rarely read, hear and see as much about eteaching?

Pedagogy?

I keep coming back to this topic. It is so vital to everything to do with teaching. The term, and all that it implies, also embraces elearning.

Elearning?

By implication, the focus is on the learner, and this is fine up to a point. But it is as if what goes on in the teaching is silently implied in the word elearning. The teacher has become the silent participant.

Well I’m going to stick my neck out here and say that there is a need for a change in emphasis so that elearning also implies an appropriate involvement by a teacher.

I’m not campaigning for teacher centred learning – not at all.

I’m agitating for pedagogy to return to its rightful place where a teacher is involved in the learning, which includes elearning.

Digital indicator

A simple examination of my blog’s statistics shows that the posts on pedagogy are considerably less popular than posts on learning. Yet they were written with the same passion, care and attention I give to posts on other topics.

My hunch is that for some reason not yet too clear to me, there is less interest in the part played by the teacher than the technology when it comes to elearning.

Interesting, isn’t it?

Elearning in Second Life

2010-02-05T18:35:00.001-08:00

Teleport Star at the Ivory Tower Library of Primitives

In September last year, I ventured into Second Life (SL) to explore.

My purpose was similar to that of most educators whom I have welcomed in the short time I have been a SL ISTE docent. I wanted to find out what SL could offer as an elearning environment.

I now have a clearer idea of its worth and potential.

University of West England - SL

The near-reality of much of the 3D simulation offered by SL is a valuable element – it is a key quality of this elearning platform. However, its aesthetic charm may dull even an educator’s appreciation of the true value of what SL can hold for a learner.

I enjoy the fantasy aspect which is so often present when I’m in SL. The huge variety of costume, and the opportunity available for disguise, make it splendid for roleplay. This aspect of SL has great potential to extend the imagination of the participant.

There are a number of features that identify SL's genuineness as an authentic elearning environment:

The people

Second Life is an environment that embraces people. This quality alone brings authenticity.

There is a wide range of ways of recognising the presence of people, wherever the participant happens to be in SL. Channels to engage in communication between those who are online are easy to use. They can be facilitated in many different ways and at different levels. They are certainly not limited to simple txt or voice chat.

Even body language can play its part in exchanges between people.

ISTE HQ, ISTE Island - SL

The sharing culture

There is a culture of sharing that is clearly evident among people in SL. This has possibly arisen through recognition of the need for assistance, sharing and collaborating when people first come into SL.

The cultural practice of sharing tends to be passed on. And it is accomplished at different levels, from a brief offer of situational help between two strangers at meeting, to organised sessions where experienced trainers can volunteer skills to others who are less competent.

The music

SL presents music to its participants through various pathways, either live, pre-recorded or streamed directly from international radio stations. YouTube plays its part in all this, bringing music, new and old, as well as videos on many other themes to the eyes and ears of participants who have full control over audio levels within a full range of different sound channels.

The medium

Within the first few weeks as a visitor, I was able to engage in the construction of the digital stuff that is the fabric of SL. I don’t think there is another elearning environment where participants can so freely make use of the componentry and structure that comprise the environment they are in.

Many of its cultural environments provide support for this engagement, through classes provided voluntarily by experienced exponents of the craft.

Two main techniques that contribute to this are building and scripting. They go hand in hand, employed in the construction of the simplest thing such as an item of jewellery, to the most complicated assemblage of the foundation of the environment itself.

For the motivated learner, there is a copious amount of well-laid-out tutorial material to be found in centres throughout the environment. Splendid examples of these are the Particle Laboratory Learning Centre and the Ivory Tower Library of Primitives, where a learner can acquire knowledge and skills on the fundamentals of building and scripting.

It is at centres like these that both beginner and experienced developer can visit and gather pearls of 21^st century wisdom on the construction of the digital fabric of Second Life.

Standards, Statistics and Steps Forward

2010-02-01T17:22:00.000-08:00

It looks like John Hattie’s words of wisdom may well have been said in vain. Implementation of the New Zealand National Standards for primary and intermediate school pupils starts today.

School boards and principals are not convinced that there is much to be gained by applying the standards. They have numerous reasons for their beliefs. Many school boards are planning to boycott their use, which would be illegal.

Nevertheless, government approval has been given for the campaign to persuade communities and school boards of the usefulness of the standards, at an estimated cost of $26,000,000NZ.

The pros and cons

I listen to the arguments that abound in the national news, buzzing with the debate between the parties in favour of using standards and those against. Some politicians who were originally in favour of the standards are now arguing against them. I’m amused at what I hear.

Here’s an example. There is argument of dismay expressed about the 25% of children in New Zealand who are well below average in literacy abilities, an average which was no doubt considered when setting the literacy standards in the first place. The argument is that the introduction of standards will help those in that well-below-average group.

I wonder if some of the contributors to that argument can understand what a distribution is, and the significance of an average based on that same distribution. Misguided use of statistics, even by authorities, is not unknown in disciplines other than education.

People statistics

In the late eighties, the Plunket movement was very enthusiastic, as it is today. Mothers with newborn children can choose to be visited by a Plunket nurse who administers advice when needed and who makes regular checks to record the development of children under their care.

I knew a young family back then. Murray and Pauline who is a nurse, had a beautiful bouncing baby daughter. Both Pauline and her husband were petite people of delicate build and stature. At birth, Elizabeth was a small baby. The presiding doctors agreed she was normal for her birth weight. She was a healthy child who developed well in all respects.

One day I walked round to see the family only to find Pauline quite upset. She’d just had a visit from the Plunket nurse who’d said that Elizabeth was well below average in both size and weight. Pauline had been told that she should ensure Elizabeth was given the food required to lift her weight into the ‘normal’ range.

Pauline felt insulted and annoyed. Her reasoning was implicit. A petite newborn from parents of small stature would be expected to grow into a petite child, and subsequently mature to a petite adult. Over the years we found that was exactly what happened.

Furthermore, Elizabeth’s potential to maintain this has been with her since birth. It comes down to the difference between body size and body development. These measurable quantities are not the same.

The Plunket movement in New Zealand do a deal of good work in monitoring and caring for the health and welfare of the very young from birth. But the interpretation of the growth chart by the nurse indicated that Elizabeth’s data was being clearly misunderstood.

Academic parallel

There is a parallel in the academic progress of children who are developing normally. That’s not to say that a child who is below what’s considered ‘average’ at an early age won’t continue to develop to have useful and perhaps even above average abilities in the future.

But there is always going to be 25% of children who are well below average in literacy ability. Any standard based on what is expected of an ‘average’ child will indicate this when applied to a fair and random sampling from a nation’s children.

I applaud the arguments that are saying let’s improve the nation’s academic achievement through good teaching. Forget about assessment of the child at early stages as a comparison with what’s considered ‘average’. Let’s look towards progress and development in the child.

My hunch is that the introduction of standards will not bring about an understanding of what is good to look for in child development in literacy, numeracy or any other ability. Instead, it is likely to serve as a measuring stick for a whole range of things unrelated to child development.

Elearning Patterns and Predictions

2010-01-26T18:02:00.000-08:00

The Band Shell - ISTE Island

In 1972 I took my first permanent teaching job in an elite Edinburgh secondary school. Just the year before, it had been a private school. James Gillespie’s High School (JGHS) always prided itself on its high standard of education.

A maximum class size was among many standards that JGHS maintained. It strove to have no more than 25 learners per class. The belief was that a finer relationship between teacher and learner could be attained. Through this practice, significantly better educational successes were achieved.

The number of scholars who left JGHS to take up business careers, or went on to higher education, was proof enough of this accomplishment.

It was a fantastic start for me as a teacher to be with classes of this size. But it was certainly no preparation for the learning environments that confronted me in teaching positions I took up after that time.

In 1974, I had a form class of 36 learners in a school that maintained an average class size of 35.

An elearning counterpart

Almost 30 years later, research into educational achievement through elearning methods suggested that there was an optimum size for elearning groups led by a teacher.

In any group of elearners, there will always be those who can be considered ‘active’ – others who learn despite their apparent inactivity in engagement with a teacher or facilitator – and those who are neither active nor engaged significantly in learning. Time has to be distributed fairly in attending to the needs and wants of each these groups.

An e-teacher who has more than 15 to 20 ‘active’ learners in a group is always extremely busy. When the number of active learners increases much above 20, strategies have to be developed and practiced to cope with the constant learner-teacher activity that inevitably occurs in those environments.

Symptoms of stress and exhaustion are inevitable in any teacher who succeeds in engaging enough learners so that the active group comprises much above 25. My own experiences of this have been confirmed by those of my colleagues teaching in e-environments similar to my own.

A recent experience

The Band Shell - ISTE Island

Recently, I’ve been actively engaging in discourse with groups of people in Second Life (SL). In the months that I’ve assiduously studied in this networking environment, the number of ‘friends’ in my Friends List has slowly increased. The size of my list is now well over 60.

Within that group is a sub-group of 15 to 20 friends who actively use instant messaging (IM) to contact me whenever I am online. It is a great experience to network with people in this way. Not all of this is done locally – that is to say, my avatar is not necessarily appearing on the same screen as the avatars of those who are IMing me.

Of late, I have found it difficult to be online while following any intended single pursuit. Two weeks ago, I became an ISTE docent, as avatar Kallan. In adhering to the expected commitment that comes with this office, I discovered that my group of ‘active’ friends caused me significant concern when attending to docent duties on campus.

At first, I was torn between being seen to be ignoring my friends, while attending to a duty which I enjoyed. Even sending messages of apology to IMing friends was an activity that I found distracting while attending to docent duties.

I’ve since learnt from other colleagues in similar SL situations that they often simply ignore the incoming IMs during the time that they are occupied with more immediate activities. Obviously they too have difficulty reading and responding to incoming IMs when engaged in other cerebral activity.

Elearning environment

In translating this to the elearning environment, I can see clearly how a teacher can become stressed and overworked. There is the part that is played by commitment. There is also the aspect of prioritisation.

Who gets priority from the teacher in a learning environment?

When a teacher is actively assisting several learners together, how does she cope when a learner puts forward, out of the blue, a desperate plea for help?

What strategies can she employ to ensure that this learner, who may well be one who has never before communicated directly with her, gets the necessary immediate support?

What provisions must administration provide in a school to ensure that the number of active learners in a teacher’s group is kept to a manageable level?

How can administration ensure that teachers are not forced to adopt strategies to disengage themselves from needy learners in order to protect their own stress levels?

On Censorship and Human Nature

2010-01-22T17:14:00.001-08:00

WARNING - The content of this post may disturb some readers.

The vagaries of censorship are mentioned throughout Hillary Clinton’s recent speech advocating Internet Freedom. Censorship is an action that often takes place behind the scenes. It is sometimes difficult to detect. You can be sure that someone somewhere will be confused, disturbed, annoyed, or even enraged when its occurrence is noticed.

Lately, printed news has come under threat. There is a belief that blogging might replace newspapers with a more up-to-date, less censored conduit. As well, the Web2.0 channel is purportedly a space for open debate and discussion.

Well, I wonder about all this. I believe that there is a place for censorship. Furthermore, my experience tells me that censorship is alive and well and is existing quite comfortably – in the blogosphere.

By the way, this post is not meant as a rant.

Moderation

During my first month of blogging I was introduced to some of the technologies that permit a blogger to choose whether or not a comment is published. Comment moderation is such a facility.

Some blog applications can even permit the content of a comment to be edited, before or after it is published. Comment moderation also gives bloggers relief from the increasing nuisance of spammed comments.

Hand in hand with all this is the idea that, through the provision of comment guidelines, commenters can sometimes be given the opportunity to learn what is likely to be accepted by a blogger on his or her blog. (Here’s a link to mine.)

Comment guidelines give the valid reasons for the culling of comments that may be in contravention of the blogger’s guidelines.

Biased opinion?

But comment guidelines are not the only criteria that may be used by a blogger who culls a comment. Am I not entitled to delete any comment that appears in my list of comments to be moderated, whether or not it meets all criteria in my comment guidelines?

How could I be accused of any discrimination even if I do cull comments containing valid opinions other than those that are aligned with my own? Who’s going to know?

You might say, “But isn’t this still a form of raw censorship?” Well of course it is. It also stymies healthy debate and discussion.

Okay, I’m being a tad hypothetical.

Or am I?

My quality comments

Over the years that I have been actively commenting on blogs, I‘ve witnessed this form of censorship. Of all the hundreds (perhaps thousands) of comments that I’ve entered against posts on other blogs, there have been a significant number, through the bloggers’ discretion in comment moderation, that have never appeared on the Internet.

You could say that this is a reflection on the quality and calibre of my comments. Well, there are enough of them still left out there. Take a look and judge the quality and calibre of my comments for yourself.

But I have always been careful to note, when my comment was removed or excluded, if the blog had any associated comment guidelines that I may have contravened. Most bloggers do not provide comment guidelines. I put it down to raw censorship.

So you may think that the blogosphere is entirely a place for freedom of expression. Just check when you leave comments on posts that have comment moderation. You could be surprised at the proportion of your comments that never appear on the blogs you post against.

On Creativity

2010-01-19T00:57:00.001-08:00

I took my daughters out for a coffee the other day. Just before we left, Hannah who is age 19 and the older of the two, stepped out of her bedroom looking like a Vogue model. I was charmed that she took time and effort to change before going out for coffee with her old dad.

“I like your outfit, especially the belt”, I said as we got into the car.

“Two dollars in a second-hand shop”, she quipped with a cheeky smile.

That’s one way a second year Art student at AUT demonstrates her creativity to the world – by choosing appropriate clothes to dress smartly on a minimal budget.

Did she have to study Art to express her imagination this way? Certainly not. Anyone can do it if they have a mind to.

But Hannah worked very hard to secure her place in her course at AUT. When she studied Art at High School, she created many different things. Not everything she did was as successful as she’d like it to have been. But she did it all the same. It all contributed to her portfolio – time after time.

To me, the difference between the artist and the non-artist
is that the artist is the one who does it.
– Helen Garner

If a thing’s worth doing . . .

When my son, Jack, was to be married a few years back, I wrote a waltz in honour of his lovely Irish bride, Ailish. She had told me that she loved dancing to waltzes. As it happened, she liked the tune I wrote for her. I commissioned a local Irish dance band to play at the wedding.

A musician friend of mine who was a member of the band obviously didn’t like my waltz. When the band was rehearsing it under my supervision, he asked me why I composed stuff like this.

I explained that the alternative was that I did nothing at all. Then the bride would not have her own waltz for her wedding day. He quietly picked up his violin and played the music – beautifully.

Creativity has to be nurtured

Creativity is so delicate a flower that praise tends to make it bloom, while discouragement often nips it in the bud. Any of us will put out more and better ideas if our efforts are appreciated.
– Alex F Osborn

The connection between Art and creativity is so intimate, it is almost impossible to define a difference between the two. One thing is clear, and that is that creativity has first to exist before Art comes into being. Creativity tends to be the easier to recognise, while identifying Art can often be an elusive and subjective assignment.

Schools have a big part to play in encouraging creativity in learners.
But they are not the only important influences, and this has been demonstrated by the work of some of the world’s greatest artists, many of whom were influenced by factors well beyond the precincts of the school grounds.

The importance of what is within us

The mind inhabits a complex organ. The self has to be nourished from within. Two undoubtedly brilliant artists in two discrete disciplines, who lived their lives in different countries and in separate centuries, had very similar views on what nurtures and brings out creativity from within. Check them out.

Go cherish your soul;
expel companions;
set your habits to a life of solitude;
then will the faculties rise
fair and full within.
– Ralph Waldo Emerson

When I am . . . completely myself, entirely alone . . . or during the night when I cannot sleep, it is on such occasions that my ideas flow best and most abundantly.
– Wolfgang Amadeus Mozart

On the Hypotenuse

2010-01-15T13:44:00.001-08:00

The area of the square on the hypotenuse of any right-angle triangle
is equal to the sum of the areas of the squares on the other sides.
Pythagoras' Theorem

I was hopeless at Mathematics when I began High School. Teachers despaired at my ineptitude. But I had a natural interest in Science.

It was mainly due to good Scottish teaching, and a genuine willingness on my part to engage in learning, that I studied Mathematics to a level that let me reach the highest academic levels in Science.

It was also due in part to the curriculum I followed. I believe that it taught me how to think. It wasn’t that it taught me to think. I could do that. It taught me how to think, and to be able to think in specific ways.

In the 1970s, I taught High School Mathematics to senior level.

Recently, I have become familiar with fundamental changes in the way mathematical thinking is taught in High School in New Zealand.
I suspect that these are similar to changes in the Mathematics curricula in other western countries.

Get it right

The Euclidean proof of the useful Theorem of Pythagoras was one of the things I had to learn for my early qualifying examinations at High School. My mother learnt the same proof when she attended High School.

Euclid’s proof was taught in New Zealand schools until changes were made in the curriculum towards the end of last century (20^th). It is now supplanted by what I’d call a non-proof. What young minds are required to study about the Pythagorean Theorem in New Zealand today is certainly not a proof of it.

Euclid’s proof is based on the properties of rectangles and of triangles that are each of the same shape and size – as well as associated geometry ideas involving these shapes drawn between parallel lines. There are several hundred proofs of this fundamental theorem. Some are outlined in Wikipedia. A few I learnt at High School.

All of the proofs I learnt permitted me to understand, not only how the Pythagorean Theorem can be proved, but also what it is to know the significance of a universal proof. It is a way of thinking that permits a learner to appreciate that a proof needs to be watertight.

What does it prove?

Euclid’s proof can be applied to ANY right-angle triangle, not just a few special triangles. Therein is the difference between what used to be taught and what is now taught.

In High School today, a learner in Mathematics is instructed on how to show that a given right-angle triangle has the Pythagorean property. The instruction is not about any right-angle triangle, but applies only to a particular right-angle triangle that the learner draws.

Essentially, learners follow a recipe that shows that the Theorem may work for their triangle. It provides no real understanding of proof.

Here’s what they are instructed to do:

Learners in Mathematics are shown how to draw a right-angle triangle on a grid, using simple mathematical drawing equipment. They are also shown how to draw squares on each of the three sides of the triangle. By counting the number of grid squares that make up each of the squares, they can show that the Theorem is followed approximately.

Higher thinking

While this recipe permits the learner to practice skills in using drawing equipment, it provides no understanding of a mathematical proof.
It does not even show conclusively that the Theorem works. However carefully it is done, not every attempt at adding the squares will show that the Theorem is precise. Check out the squares shown above.

One can argue over the need for the knowledge of how to prove the Pythagorean Theorem. But the significant learning is nothing to do with that knowledge. The thinking skills learnt that permit the learner to understand what a watertight proof is all about are really what are far more useful and relevant to higher thinking skills.

This is the whole point of teaching the proof. It has the potential to permit the learner to realise the significance of a theorem that can be applied universally, and why it has this property. It is a way of thinking analytically that is not being taught today.

Unpacking Pedagogy – assembling elearning resources

2010-01-06T22:13:00.001-08:00

At the beginning of last decade, I attended a session for teachers. The topic was pedagogy. There were about a dozen participants – teachers from early childhood through to senior secondary.

The facilitator asked that we consider what was meant by ‘pedagogy’. We each wrote a few sentences about it on a sheet of paper, to be read and discussed later in the session.

I was amazed at the diversity of ideas that were revealed. It seemed that from a significant group of teachers, no two had the same idea of what was meant by pedagogy. Some said it was to do with the lesson plan. Some indicated that it was about how things were taught.

A few spoke of proven teaching methods and theory. Others mentioned how the learner could be involved. Of course, it could encompass all of those and more.

But the miscellany of ideas brought forward was so varied that it was difficult for me to see any commonality among it at first. I wondered about this. I wondered that in a group of a dozen or so teachers, opinion about the meaning of pedagogy could be so disparate.

Pedagogy a practice

Fortunately, as the session evolved, things became more distinct. We agreed that pedagogy was to do with what was practiced and what was found to work best in particular learning situations. It was not some idea or strategy for teaching that was dreamed up on the spur of the moment. It does not work like that.

Pedagogy is the product of a cycle practiced by a teacher, and this has components that can be considered as part of an action research cycle: theory and recognised practice – planning – application – evaluation – reflection.

Wikipedia explains pedagogy as “strategies of instruction” and “the correct use of teaching strategies”. It gives the literal meaning from the Greek as, “to lead the child.” This description suggests a definite focus on how to go about teaching a young mind.

I usually have adults in my cohort of learners. Some of them are at least as old as I am. Is using pedagogy appropriate when teaching adults too?

Elearning resources and pedagogy

Certainly, pedagogy has to be involved when digitally created resources are being chosen for a learner – scaffolding – level – cultural appropriateness – timeliness of use. It could be argued that this is when the ultimate pedagogical decision is made – whether to use a resource or not, and if chosen, how it is to be used.

What relevance does pedagogy have in the creation of digital learning resources – of the type that may be designed and built by an instructional designer? Is pedagogy any use to the instructional designer? Should its application be restricted to the realm of the teacher?

The construction of a resource and its pedagogical usefulness does not happen by chance. If it is sound enough for a teacher to contemplate its use when applying correct pedagogy to a learning situation, then it follows that a fair amount of pedagogy also has to be considered when the resource is built.

What components of pedagogy also contribute to the considerations that are part of the creation of a resource? What pedagogy is appropriate? How much should involve both teacher and designer when pedagogical considerations are being made? What, if any, should be left to the teacher?

Second Life Scripting Colour Code Explained

2010-01-03T17:48:00.001-08:00

I thought I’d start the year off with a colourful post. I’ve been doing some building in Second Life (SL) recently. I got stuck when I came to interpreting how the colour codes work when scripting some effects.

Perhaps I should explain for those who are not so familiar with SL.

All of SL, including the avatars that frequent it, is constructed from what are known as prims, or ‘primitives’ – polygonal three-dimensional shaped objects, like the ones Kallan demonstrates here.

Of course, not all that can be seen in SL is made entirely from these primitive shapes alone. They can be distorted by an effect, called sculpting, to reshape, or ‘tortured’ by changing their shape and size by other means.

Painting things in SL

Colouring, or painting prims can be done in at least two ways. Choosing a single colour by using the colour picker, is a way of painting. The S-shaped sculpted sphere, above, was coloured this way.

Another is selecting a texture, which is really an uploaded image, and using this to give a defined pattern or intricate detail to the prim.

The picture here shows my friend Lara Nguya wearing a pendant that is decorated and coloured using this texturing method.

The standard RGB colour code is used. Each colour is defined digitally (8-bit) by its Red, Green and Blue components – shown as numbers between 255 and 0, in so-called vector arrays.

The code for white is (255, 255, 255) and for black is (0, 0, 0). All other available colour combinations in the colour picker occur as permutations between these two vectors.

Scripts

One way of imparting effects to objects in SL is by using scripts. In Lara’s candle, for instance, she uses a script that gives the wick the effect of a flickering flame.

When it came to scripting, I was completely baffled at first by colour codes and how they worked. Lara, showed me that an arithmetical code is used in scripting – different from the 8-bit coding used for colours in non-scripted prims.

The arithmetical code embraces a similar RGB range of colours, with some minor limitation in the range of hues available.
The RGB components are represented by numbers between 1 and 0, instead of 8-bit digital numbers between 255 and 0.

An easy conversion

Lara explained it to me this way:

Whereas 255 is the maximum number allowable in the 8-bit digital code, the corresponding maximum number is 1.0 for scripts and for some other uses in SL.

This means that any RGB code has to be converted to the equivalent code before it can be used in a script. The numbers in the 8-bit digital codes must be divided by 255 to be corrected for use in scripting.

The code for white used in script becomes < 1, 1, 1 > and the script code for black becomes < 0, 0, 0 >.

(48, 128, 20)

The arithmetic in the code conversion for sapgreen is as follows:

48 converts to 48/255 = .19

128 converts to 128/255 = .50

20 converts to 20/255 = .08

So sapgreen 8-bit digital code (48, 128, 20) becomes < .19, .50, .08 > .

Another example is blueviolet. Its 8-bit digital code is (138, 43, 226). The code for the colour used in script is < .51, .17, .89 >.

The same process can be used for any other colour expressed in 8-bit digital code.

I am grateful for assistance and advice given to me by Lara Nguya.

Elearning Prediction / Hope 2010 – Next 10 Years

2009-12-31T22:15:00.000-08:00

My prediction and hope for 2010 are tempered by what I learnt and gathered in 2009 and before that. However, my hope does not match my prediction.

I suspect that what I hope happens will not come to pass.

I’ll not dwell on the particular. That is too narrow for the future. Instead, I’ll attempt to look to the bigger picture of where a Nirvana in elearning might lie.

Surmise

Commercialism and consumerism will rise with renewed vigour, despite the recent and global economic collapse that many experts say was brought about through, among other things, flagrant practices of commercialism and consumerism.

Rather than learn from past errors and misguided pathways, society will resume its hazardous journey and continue to career along a wavering and obstacle-strewn path to uncertain success.

Why do I feel this way? There are many reasons. I will cite only one elearning example here.

At the beginning of last decade (2000 – 2003) I watched the rise and fall of what might have been a brilliant concept in learning resource development – that of the learning object.

I may be wrong here – I don’t think I am. But my feeling is that financially pushy commercial factors, far larger than the budgets for learning itself, launched into the sky and eventually nosedived to destruction what could have been a worthwhile elearning concept, in the form of the learning object.

Pandora relic

I have one hope for this year and for the rest of time.

Sheryl McCoy’s recent post, Another Balkanized Technology Rip-Off, puts into words exactly how I feel about the way commercialism and consumerism have continued to hinder the betterment of society.

The drive to sell, through a strategy of planned obsolescence despite genuine need, continues to come in the way of establishing real expertise in the use of technology. It stymies creativity. It comes in the way of progressing to better things, while purporting to advance and progress towards improvement. It wastes time, resources and money.

I have worked through a decade of watching incompatibles, non-connectables, lack of connectivity and even incompatibility between different versions of the same commercial devices/applications/appliances.

I’ve wracked my senses, grappling with upgrades to versions of machines, computers and their applications. All in an attempt to continue to use these for the purposes that I had worked to acquire consummate ease in and reasonable expertise in.

What I discovered was that I was grounded, once again, when the latest version (of whatever) was released. It made me consider seriously and review any further dubious opportunities for ‘upgrading’.

Valuable opportunity

I hope that we can learn from the mistakes of the last decade, and of last century. Let’s not push mistakes into the past as history to be forgotten. Let’s not claim we are assured success by simply ‘moving right along’.

Let’s start putting to good use what can be salvaged in learning from our past mistakes and successes, and move to a richer and prosperous future.

Thinking and Learning

2009-12-26T18:16:00.001-08:00

A well-meaning friend once lent me a book and said, “You should read this. You’ll learn how to become very rich.” He also told me that the secret clue to becoming wealthy was found on almost every page, and that it also occurred several times on the first page.

I read the book. It is well written – a study of human nature – an interesting compendium of anecdotes and tips, directed mainly at sales-people, but not exclusively. I found the clue to becoming wealthy several times before I’d even finished reading page one.

But it didn’t help me become wealthy.

The book was Think And Grow Rich by Napoleon hill. The clue centred on the word ‘desire’. To become rich, first you must have the desire to do so.

Of course, the main reason I could not use the book for its intended purpose was that I had no burning desire to become wealthy. I’d like to be, but the necessary burning desire isn’t there.

The book did make me rich, however, but not in a financial way. It made me think about how some people can be so engaged in learning, they suck up skills and knowledge as if they were vacuum cleaners. It gave me clues as to how some people seem to learn, almost as if by instinct, and never stop learning.

Teaching and learning

When I taught Mathematics at Rongotai College, Wellington, I always asked for an Upper Fifth Mathematics class when classes were allocated to teachers at the beginning of the year. These classes were of students who had failed to qualify in Mathematics the year before.

Every year, I had a lot of fun with the learners in the Upper Fifth. I really enjoyed teaching them. I used to hold classes after school for those learners who felt they needed some extra help and tuition. It was rewarding. The after-school class was always full, though not all who attended were from my own Mathematics class.

There was one attribute common to all who attended.

Hooks for learning

Teachers speak of engagement, and practice strategies to improve student engagement in learning. Some put a lot of effort into stimulating interest in their learners and this is admirable. They look for and find the hooks that catch some learners and get them engaged.

Learning, and achieving through learning, is a bit like growing wealthy. There are many contributing factors, not all of which are related necessarily to innate ability. The learner who has a burning desire to learn will learn, despite apparent handicaps, whether it is learning to become a musician, learning to play chess or learning to read.

But to do this, they must also be able to think to apply their desires effectively. It is in teaching learners how to think that permits those who have the desire to learn to reach their goal. It ignites the fire of learning within them.

Few people think more than two or three times a year. I have made an international reputation for myself by thinking once or twice a week. – George Bernard Shaw

Compassion - What I Learnt About Fishing

2009-12-20T13:47:00.001-08:00

As a child, I was never aware of any real ability I had, other than to get into mischief or catch cold. I discovered these rich talents early on. Even as a ten year old, I bumbled along with no appreciation of any real capabilities I might have had as a human being.

My grandfather used to take me fishing. I got a buzz from the wonderfully natural places we visited. My head got filled with the summer sounds and scenery of these spots. But I was hopeless at catching a fish, having too much compassion for the poor hapless creature to get any enjoyment from the event.

I recall stabbing my finger with a fishhook, being more astonished at how easily the needle-sharp device entered the tissue than the searing pain it caused. It stuck firmly, deep in my fingertip.

My grandfather was annoyed and looked at me sternly for a moment. He fumbled in the pocket of his fishing jacket and took out a small pair of pliers, holding them tightly in his hand.

With his other hand, he grabbed mine and lifted the injured finger so high that my shoulder hurt. I watched to see what he would do.
I thought he might pull out the hook with his pliers but I was too dumb and curious to close my eyes and brace myself.

He deftly pinched the hook in the jaws of the pliers and gave it a powerful and sudden twist. What I saw made my eyes pop.

Contrary to what I’d hoped, he didn’t pull out the hook. Instead, the business end of it reappeared through the tip of my finger – a tiny fluted barb, tinged with the blood that dripped from the newly pierced hole.

Grandfather carefully snipped off the barb with his pliers and swiftly pulled out the remains of the hook. He explained that the barb would have torn my finger apart if he'd remove it the same way it went in.

As I held my sore finger, wrapped tightly in a piece of bandage,
I reflected on what it might be like for a poor fish who unwittingly takes the bait.

I stood beside a brooklet, that sparkled on its way,
and there beneath the wavelets, a tiny trout at play,
as swiftly as an arrow, he darted to and fro,
the gayest of the fishes among the reeds below,
the gayest of the fishes among the reeds below.

Angler there was standing, with rod and line in hand,
Intent upon the fishes, a sportive fearless band,
“`tis vain” said I “good neighbour, to fish a brooklet clear”
The fish will surely see you upon the bank so near.
The fish will surely see you upon the bank so near.

But skillful was the angler, and artful too,
The crystal brooklets depths defying, he hid the fish from view, and then he skill renewing,
the fishes unheeding took the bait,
and I was left lamenting, my tiny troutlet’s fate,
and I was left lamenting, my tiny troutlet’s fate.

Experience and Qualification

2009-12-18T23:59:00.000-08:00

I’ve been reflective in my thoughts on where teaching and learning, training and higher education have been leading us recently.

I find it curiously odd that there seems to be a cogent drift away from the value of qualification, in those who are actively engaged in creating educational and training resources. This, at a time when experience is already not held universally in high esteem.

By qualification, I mean a formal standard, diploma or degree, conferred by an authorised and antonymous education or training body.

By experience, I’m implying months or years actually practicing a discipline, in whatever role the position requires.

I have tremendous faith in the youth of today, so I’m not denying their worth and value. They have unbelievable potential and the future of the world as we know it lies undeniably in their hands.

But in the past decade or more, there has been a move away from recognising experience in the workplace. Fresh minds – and let’s not deny it, youth – and the promise of creativity coming from those, have been put above the true and proper value of experience.

And now, we might be misled into believing that qualification could also be discarded.

I put it to you, that by severing the effective combination of qualification, experience and innate ability of the potential appointee to a position in the workforce, we are not only doing a disservice to the workplace, we are putting the future of the world at risk.

Learning - A One Way Street?

2009-12-15T21:35:00.000-08:00

Robert Winston got it right when he corrected John Campbell on TV3's Campbell Live today. John had remarked that he was learning a lot during his interview with Lord Robert, when the surgeon politely pointed out that he too was learning a lot.

Lord Robert is Professor of Science and Society at Imperial College, London. He made the point that the brain is an ever-changing organ where (learning) connections are being made all the time.

He said that when he left the TV studio, his brain would be different from how it was when he came in. This is because neural connections would have been made in Lord Robert's brain during the time he was in the studio. He would have learnt new things.

Empty vessels

'Filling jugs' has been a favourite metaphor for teaching and learning.
It implies many things erroneously. Among which is that teaching is a one way process of transmitting knowledge from teacher to learner.

My teacher training lecturers at Moray House College of Education, Edinburgh, in the 70s, were before their time. They each passed on their message. But a common theme was that teachers should never stop learning.

Part of good pedagogy is sharing the journey with the learner. There is as much for the teacher to learn on the way as there is to be taught.

If ever there is an idea that is ‘learner centred’, that one is!

What I Learnt About Learning 2009

2009-12-12T22:57:00.000-08:00

On The Learning Circuits Blog, Tony Karrer’s Big Question for December is What Did You Learn About Learning in 2009?

I reviewed my posts over the year, following Tony’s advice, looking for things that might be relevant to this. There are several recurring themes. Some I’ve also met on other bloggers’ posts. I've selected two main ones that are related - the quick pill and learner engagement.
I’ve a lot of questions, and few convincing answers.

We are often dogged by tradition when it comes to theories of learning. They are many and varied. But it’s too easy to discard time-honoured philosophies and replace them with something new and seemingly innovative.

Thinking and learning

One theme that’s prominent is related to multi-tasking, among a series of other linked ideas that took my interest this year. It prompted me to think of how ideas on thinking and learning evolve in the first place.

The discussions I’ve followed on the merits and demerits of multi-tasking seem to be at cross–purposes to each another. Those who believe that it can be done effectively are seemingly oblivious to hard evidence that it just can’t be done.

The quick pill

Learning is not often easy. It nearly always involves concentration, thought and patience. A person looking for a learning panacea (don’t all learners do this as some stage?) may end up having to make a strategic choice, and stick with that long enough to see if it works.
It doesn’t always work. It’s no different for the teacher who is looking for a quick pill to offer learners.

Teachers have a more difficult job in many respects, for they have first to assess the learners’ progress, and interpret these assessments to see if a method works. Teachers who believe that assessment is not required or who neglect the need for these are short-changing their learners and fooling themselves.

Learners who know something about metacognition may have more facile routes to similar destinations. But they also have to assess effectively their own progress before they know if a learning technique is any use to them.

The smorgasbord of tips and ideas to do with learning that learner and teacher confront, tends to be so much in-your-face - a plethora. And there are conflicting arguments in abundance over the merit of each tempting morsel – which one works for what situation, etc – everything from where the learning is sourced, to how it’s supposed to be assimilated:

Are books a good idea? Should learners be able to read AND listen to mp3s? Does listening to music really assist learning? What type of music is best if it does? Is the Internet a fast option? Can a learner listen to or watch instructional DVDs and read the Internet at the same time?

Does the learner have a so-called digital-immigrant’s barrier to accepting these learning technologies? If so, what can the learner do about it if they have?

What other barriers to learning can impede the progress of the would-be-learner? The list goes on.

Learner engagement

Another theme I’ve seen a lot of this year is learner engagement. Again, a whole set of questions arise out of this.

What is it that hooks the learner? How can the hook be put to further use? Is there a way of maintaining an effective level of engagement once initiated? Is it individual engagement or is a community more likely to achieve a better level of success?

What influence does the support of the learning environment have on learning? Are parents, partners or other significant people important to the learner when it comes to motivation?

What circumstances are best for learning – situational or isolated instruction? Of these, are the benefits associated with either, dependent on the occasion?

Where does praising the learner fit into all this?

I find this difficult. I’ve covered so much ground this year, it’s a hard task to prioritise and select the most significant ideas or the most interesting thoughts, for I’m really not sure of their relative importance.

They are all fascinating in their own captivating way. The practice of the good teacher is to select, revise and re-activate from past actions those that work best in the ever-changing environment of learning.

What's In A Name?

2009-12-06T01:19:00.000-08:00

A rose by any other name would smell as sweet – William Shakespeare

Evening Standard columnist, Frank Furedi, believes that the educational crisis facing Britain today is in part due to the way objective academic standards are being defined and asserted in the classroom.

His claim is that society seems “to have given up on adult authority and the idea that the person who knows best in the classroom is the teacher.” He believes that “education requires the conscious and regular imposition of adult authority.”

I was reminded of Furedi’s opinion when learning recently of the debate over the move by principals and teachers in some New Zealand primary schools to have pupils call them by first name. Some teachers believe that learners bond better with their teacher when they call them by their first name.

Anthropologist James Urry claims that removing the age-based hierarchy empowers children before they have the social skill to cope with it.

Canterbury College of Education associate dean, Barry Brooker, was reported as saying that using formal titles develops a demarcation between teachers and students that gives teachers the authority to do their jobs properly.

Do teachers need authority to do their jobs properly?

At The Correspondence School of New Zealand (TCS), a distance education centre, learners always refer to teachers by first name.

When I first took up a teaching post at TCS, this idea was new to me. I’d taught in different secondary schools for many years before then.

In all the schools where I taught, in Scotland and New Zealand, students called their teachers by their surname: Mr Roberts, Mrs Gill, Miss James, etc.

When I graduated PhD, the principal of the Edinburgh High School
I was teaching in announced to the school that I was to be called
Dr Allan, from now on. I've been addressed as Dr Allan, or Sir, by students in every face-to-face school I’ve taught in since.

But I had no problem when my students called me Ken at TCS.
The policy of the school was that students always referred to teachers by first name.

Other distance education centres do the same. And you know, it seems to work. I find that learners relate to me with at least as much respect as I had earned while teaching in face-to-face schools.

Are face-to-face schools so different that students calling their teachers by first name can damage the potential for effective student–teacher relationships? What do you think?

Odd Tails – a post for bloggers

It is usual for a blog post to attract nearly all its visitors during the first few days after being published. This is so much so that the term
‘the long tail’ is often used to describe the shape of the visitor profile of a typical post.

Courtesy Google Analytics

Now and again a blogger may spot an exception.

‘Digital Natives? Digital Immigrants?’ is a post I published in mid-July this year. It was popular and attracted a couple of comments.

Normally even the tail of a popular post would dwindle quickly over a period of less than a week. After two or three months, only the occasional visitor would be registered by visitor tracking.

I use Google Analytics (GA) to track one sector of visitors to my blog.
It gives a fair indication of comparative popularity.

The July post is an exception to the long tail trend. Its visitor profile is at the top of this post. It has received recent attention of a magnitude not unlike what might be expected of a newly published post, yet it was published over four months ago.

I first took note of its unusual visitor profile when comments started to appear, again, as if out of the blue. It has since attracted a significant number of comments.

Occasionally posts generate very long tails that never really dwindle to nothing. Working With Online Learning Communities is such a post, published 1 April 2009. Its visitor profile shows recent steady traffic.

Posts with visitor profiles of this type tend to have been cited and linked on popular blogs or web pages.

Isn’t it heartening that not all posts receive the same fate as a time-capsule?

Science, Context and Humour

2009-11-30T03:04:00.000-08:00

When was the last time you laughed at a joke? Where did you hear it? Was it on TV? Or was it on a video clip or podcast?

Susan Greenfield says, “Everything that happens to you will be seen in terms of previous experiences.“

Your brain “can see one thing in terms of something else and that’s your unique perspective”, even when it comes to appreciating a joke.

Here’s what she says:

If you are a scientist or if you are just interested in Science, you may also be familiar with the erroneous opinion that Science is humourless. A joke is a cognitive jolt based on your previous experiences. This jolt can happen even if these experiences are to do with Science.

So let yourself go! Abrogate your sense of self and have “a cognitive time” with some Science humour from Brian Malow.

Resource Success? It Bears Thinking About!

2009-11-27T19:11:00.001-08:00

How do you tell if a learning resource is successful?

You have to use it of course! Or at least, it has to be observed being used by learners who may benefit from it in some way.

But there’s more to it than that . . .

A game-based resource can be seen to be popular and for this it gets a big tick in a check-box.

But does a learning resource need to be popular to be successful?
Does the popular resource assist the learner to meet the target learning objective?

Extensive research on a whole series of resources might throw some light on these questions. But let’s just limit the discussion here to one resource.

How do you know if a learning resource is effective in helping learners reach the objective or objectives the resource was designed to meet?

This needs more than just observation.

Learner focus

Attention must be focused on what the learner has gained by using the resource. This acquisition has to be very specific if the resource is to be regarded as a useful ‘learning object’.

Oops, I’ve used that term!

I know! ’Learning Object’ is not a popular term among some educators. At least the term implies that the resource actually has an objective associated with it. Whether the resource assists learners to meet the objective is quite another matter.

In fact, some very good learning resources are often found to meet objectives that are not necessarily directly related to the objective or objectives that the learners were supposed to be reaching. That’s life! Sometimes it just happens that way.

So how do we know when a resource is meeting its objective?

It’s taken me a few hundred words to get to this nitty-gritty stage.

How do we know the resource is really achieving
the learning that was intended to happen?

As obvious though the answer may seem to be, it is often something that’s completely overlooked when a resource has been planned, crafted and produced for learner use.

Follow up

One of the important stages in the development of any course module, or even one of its components, is the time consuming and difficult process of assessing its real worth. It’s one of these stages that teachers and developers would rather not get too far into, for it is both complicated and complex. And it takes a lot of time.

But it is obviously very important.It means that a series of analyses has to be performed involving the learners.

As well, it has to involve a thing called ‘learner assessment’. Oops! Another not too popular term.

That’s right! The learner has to be tested. And this is difficult, for how do we know that the assessment item designed to test learner achievement assesses effectively the objective that it’s meant to?
This brings us more or less back to where we started.

Sorry folks! It’s the dogged chicken and egg story all over again.

Before we can be sure that the assessment item is any use, first it must be tested! And of course, this always means learner involvement.

Compounding problems

We now have learner assessment as well as learning resource design to deal with. It’s a bit like the collective effect of errors, if you’re familiar with how that works.

Small errors that occur at stages of a process tend to be cumulative. They add up to one significant error in the end. Often this error can be big enough to discount the whole process.

Catch my drift?

“What does it all mean then?” you say.

Frankly, it means that teaching and learning is a difficult process to assess. The learning that could possibly take place through the planning, building and subsequent use of a learning resource by learners is actually very difficult to assess.

Can you imagine the tasks involved in checking properly a whole course made up of multiple series of resources?

Time consuming? Yes! This alone is a factor that puts teachers and developers off the whole idea of attempting that all-important final stage of checking to see if it all works.

If you think that building a successful learning resource is a quick and easy thing to do, then maybe you should think again.

Assumption

2009-11-25T21:32:00.000-08:00

Some say I have a chip on my shoulder about education.

At 9 years old, I returned to Scotland with my parents, having spent almost 3 years in Nyasaland (now Malawi). While in Africa, I was home-schooled for almost a year. I then attended St Andrew’s Primary School, in the Capital City of Blantyre, for the remainder of my stay.

I had no education in the traditional sense during the months-long journeys to and from Nyasaland on Union-Castle liners. The unusual long routes round the Cape of Good Hope, were taken at the time of the Suez Crisis when access through the Suez Canal was unsafe.

My childhood experience of living in Africa was an enriching one, but my traditional education fell sadly behind. When I re-enrolled at Dunfermline Commercial Primary School in Scotland, I sat beside the classmates that I’d been with three years before.

They were all so far ahead of me by that time. I had real difficulty catching up. My schoolroom behaviour took a turn for the worst.

I was soon to be classified as a boy much in need of counseling, and was made to attend a series of Tuesday afternoons with Mrs Len, a child guidance counselor.

My visits consisted of sessions of being helped through tests, mainly so-called association tests and intelligence assessment, presumably to determine my state of mental health and my ability.

A beautiful glen

I recall one session in particular. Mrs Len began by asking what I did on Saturdays. I explained that I spent fine-weather days down the beautiful Glen in Dunfermline. I loved the Glen and would have spent every Saturday and most Sundays there if I could.

“Why don’t you go to the films on Saturday mornings?” was her response to my story. “That’s what lots of other children do.”

I explained that I didn’t like the movies that were on at the local cinema.

“Why not?” she asked. “These films are specially chosen for children!”

Gangster cadillacs

I explained that I didn’t like watching cowboys and Indians killing each other, or wars with ‘Japs and Gerries’, or gangsters hooning about in Cadillacs, or cops and robbers blasting themselves to bits.

That was in 1957. I was ten years old.

Not that long after the war, it was still acceptable for children to see all this violence. Mrs Len’s assumption was that it was good for me to be subjected to hours watching movies of people shooting at each other.
I had a different opinion.

Educational assumptions

In fact, in discounting the years of my lost education, she made a number of assumptions.

Based on the results of the tests she gave me, one assumption was that I was unfit to attend High School. Luckily I had caring parents who insisted that there was ‘nothing wrong’ with their son and that he would attend High School no matter what.

The long and the short is that my parents eventually removed me from Commercial School to enrol me in Pittencrieff Primary School nearby.

A year later I attended High School. In 1965 I became a student at Heriot-Watt University, Edinburgh. I left that place of education in 1972 with a Doctor of Philosophy degree.

So I’m not knocking Scottish education. All things considered, I firmly believe that the system served me well. But when I think of my last months at Commercial School, there were several odd and perhaps invalid assumptions made by my teacher, the school I attended and the child guidance councilor, Mrs Len, about where I stood in relation to ‘education’.

Abominable assumption

Wikipedia defines assumption as a proposition that is taken for granted, as if it were true based upon presupposition without preponderance of the facts.

This means it’s a preset notion with no factual foundation.

Assumption can present barriers and can lead to disastrous decision making. It has dogged the view of where Earth is in relation to the centre of the universe since before the time of Ptolemy. It seeded the reason why Shakespeare’s Romeo took the fatal poison.

The legal maxim that a person is innocent until proven guilty was initiated by the recognition of its fallacy. Yet assumption is often used mercilessly by legal council in leveraging notion and supposition while swaying the opinion of a jury.

One of the greatest barriers to learning is initial and erroneous assumption in the mind of the learner.

Another is initial and erroneous assumption in the mind of the teacher.

Denial - Tumbling Walls

2009-11-21T03:33:00.001-08:00

This month’s theme from Paul Cornies’ Green Pen Society is
writing about a wall you would like to see come down.

In Wellington, New Zealand, just after 6 am on 12 September, 2001,
I learnt of the World Trade Centre Twin Towers collapse.

In New York City, it would have been just after 1 pm on 11 September.
At that time the original 7 World Trade Centre building was still standing. More than four hours passed before it too collapsed.

Official reason

The official reason given for the subsequent disintegration of the 7 WTC building described that it was damaged by debris when the nearby North Tower of the WTC collapsed. Fires were ignited on the lower floors, which continued to burn throughout the afternoon. The 7 WTC building collapsed catastrophically when a main column buckled causing structural failure throughout.

Expectations don’t stack up

There were features about the collapse of the building that puzzled me.

One was that the initial damage was caused by debris, apparently ejected during the collapse of the North Tower at speeds close to 100 kilometres per hour.

Material ejected at this speed could only have been assisted by huge amounts of energy, driven from some source other than just the collapsing of the North Tower. Any bright year-13 Physics student can prove this.

Video footage screened on television in New Zealand clearly showed the 7 WTC building fell extremely rapidly. It looked like a controlled demolition using explosives.

Recent investigations from video footage have shown that the disintegration was what’s known as a free-fall collapse. It took just over 6 seconds for the top of the building to fall onto the collapsed pile of rubble that was all 47 compacted storeys.

Only an explosion-assisted collapse of the type used in controlled demolitions could have caused such a free-fall collapse. The explosives would had to have been detonated on almost every floor.

Pancake collapse

In a so-called pancake collapse of a building, the floors remain more or less as discrete layers. Contrary to expectations, however, the rubble from the collapsed building showed no sign of layering of floors at all.
Instead, it consisted of crushed concrete, dust and twisted steel.

Danish scientist Niels Harrit carried out rigorous investigations of the debris from the collapsed WTC buildings and published a report in April this year. He and his co-workers found evidence for a significant amount of a substance known as thermite in the debris.

Thermite can consist of fine aluminium dust and powdered iron oxide. When well mixed and ignited, these substances react rapidly, forming aluminium oxide, molten iron, smoke and huge amounts of heat.

Thermite was used for welding tram tracks early in the 20^th century.

Molten iron

Observations from videos taken just before the collapse of the towers showed the ejection of huge amounts of molten iron. Experiments have confirmed that these quantities of molten iron could not have come from steel structures melting in the burning building and aviation fuel. Steel girders, roasted in a burning building, do not melt and flow freely.

Until 11 September 2001, no high-rise steel constructed building had ever collapsed because of fire – yet on that day, three WTC buildings collapsed.

There has been a series of consistent analyses conducted by independent analysts. Compositional analysis shows that the molten iron ejected from the building was what’s expected from iron made during thermite ignition.

A wall

Examination of footage of the moment of collapse of the South Tower shows clear evidence for a descending series of explosions, preceding a floor-by-floor collapse – an occurrence that could only be brought about by synchronised detonation of a type used in building demolition.

I find it almost unbelievable that the publicity surrounding the collapse of the 7 WTC building was so scant. It’s only recently, in reading about the emerging evidence for the presence of thermite in the tower debris, that my initial suspicions have been wakened.

What these facts and other evidence point to is a cover-up of some huge dimension that was apparently enacted at the time of the towers disaster, and maintained over the years since. They leave questions hanging over why the planes were involved in what seems to have been a large scale and extremely well-planned operation.

Somehow a wall appears to have been successfully built around what really caused the collapse of the World Trade Centre buildings. I would dearly love this wall to be demolished so the truth of what happened in New York CBD on 11 September 2001 is revealed.

Change - A Possible Barrier to Progress

2009-11-19T21:58:00.000-08:00

Change has come up a lot in the blogosphere recently.

Andrea Hernandez prompted me to write one of my post-type comments against her recent post on agents of change:

Seeds, Serendipity, Sustainability.

I thank her for the opportunity for that reflection. Part of my comment to her ran something like this:

Always, when I learn about change being brought about, I ask questions. I ask why we are changing and I listen. The reply I get allows me to decide whether the change that's proposed is something I'd support.

If I am confronted with the question, "Don't you support change?" my knee-jerk reaction is always to ask again, "What change or changes am I being asked to support?"

If I get back nothing but an argument on change, I become suspicious that the goal of the agent for change is simply to change, without recourse to why, how, or if a proposed change is for a real benefit.

There is always the possibility that change could mean a retrograde shift - moving back to what was - or moving to situations that are of no real benefit or worse. Yet it is always assumed that 'change' is good and that it means moving forward.

Why do I think like this?

Much of the change that I have been coerced into accepting in education over many years has not been thought through beforehand. It is only years, months or even weeks later, when in hindsight, it's seen that the enacted change was not needed, or was falsely initiated, or that there was a political agenda.

So it was for me with the introduction of unit standards to New Zealand secondary education in the mid-90s and with the introduction of NCEA this century.

When I heard of the proposed introduction of national standards to primary education in New Zealand, I experienced powerful déjà vu.
I had a dizzy sinking feeling, and something inside my head shouted, “Here we go again!”

When I hear John Hattie speak about the introduction of national standards, I think, “John! You’ve got it right mate!”

Common Sense

2009-11-18T00:28:00.001-08:00

In his book, Where Have All The Leaders Gone, Lee Iaccoca claims common sense as one of the Nine Cs of Leadership.

The Ninth International Symposium on Logical Formalizations of Commonsense Reasoning, Commonsense 2009, took place this year to explore one of the long-term goals of Artificial Intelligence, that of providing computers with common sense.

Stephen Downes claims common sense is what’s needed to avoid or prevent some Internet fraud.

In 1776 Thomas Paine published anonymously a best seller 48 page pamphlet, Common Sense, challenging the authority of British rule in America.

Have you ever thought about what makes up common sense?
Have you ever tried to explain what common sense is?

Seemingly, it’s an awareness, like the ability to judge temperature, recognise directions close to the vertical, or the talent for dress sense.

Difficult to measure

We hear a lot about common sense today. It’s something that every school teacher admires. Possessing common sense seems to be one of the key attributes for achieving success – in any walk of life.

Each of us has a quantity of it – some of us have more than others.
Yet it is extraordinarily difficult if not impossible to measure, let alone define. We are more often made aware of common sense as an entity by its absence than through its occurrence.

Intelligence & noticing the obvious

The brightest and most knowledgeable among us can succumb to a lapse of common sense. Even trainee doctors can suffer a lack of it. When it comes to recognising simple clues, it’s clear that what’s required is more than just expert knowledge or even skill.

One of the most celebrated American scientists, Linus Pauling, undoubtedly possessed a fair amount of common sense in his day.
His researches and passion for what is right earned him Nobel prizes in two disciplines.

Common sense drove him to pursue research into vitamin C and the common cold in directions that have since been proven unequivocally fallacious. This is not a criticism of Pauling. I have a huge respect for all that he did in his life. But his efforts show the illusive nature of common sense and how it can direct or mislead decision making.

Is it instinctive?

If common sense is innate, does this mean that it cannot be acquired by someone who begins life with a less-than-average amount? This idea suggests that it’s like the gene for eye-colour – you are stuck with whatever calibre of common sense you had at birth.

There’s a lot to suggest that common sense is instinctive. In action it tends to be intuitive rather than contrived. Generally the common sense decision is not brought about through a process or processes involving logical thinking strategies, though the use of these cannot be discounted when common sense is brought into play.

Can it be learnt?

If it isn’t an inborn trait, how can a person ensure that a useful amount of common sense is acquired?

I’m only too aware of the rhetorical nature of these questions,
but I’m going to ask them anyway:

Is it possible to teach/learn common sense?
Can common sense be assessed?
If so, how can it be measured?
Should common sense be included as an essential part of the school curriculum, like literacy and numeracy?

It’s All Good

2009-11-15T01:52:00.001-08:00

Design from Jabberwocky

Good that we have the radio to listen to, news and weather reports – how convenient it is to hop on a bus to work in the morning – I must post that letter before last collection today – how lucky we are to receive medical care when needed – what an amazing thing to send kids off to school to learn something before bedtime – so convenient to be able to book movie tickets on the Internet – isn’t it a great asset to switch on a light in the black of night and check a window rattling in the wind?

The list goes on

We live within a complexity system called society. What’s listed above is some of what we expect from the place we live in. It’s as if it’s always been there, and always will be. If it collapsed tomorrow, the things we accept, and indeed rely on, might vanish.

This is exactly what happened when the Soviet Union collapsed in 1992. Apparently it is something that can happen to any society, within any country. It’s only a matter of time.

In a conversation on the radio this morning, someone suggested that efficiency within a society could be looked on as a threat that could precipitate collapse or at least make for a less robust society in the face of possible collapse. Funny enough, less efficient societies tend to be more resilient and more resourceful in crisis, or so mathematicians tell us.

Complexity

Less efficient societies tend to possess repetitiveness within their makeup. They embody many processes within processes that are duplicated throughout their entirety. This feature of being recursively elaborate appears to be a strength within a society rather than a weakness.

Contrary to expectation, high efficiency makes a society vulnerable. Maintaining efficiency means that the administration of resources is fine tuned, so there are fewer margins for adjustment. When things get financially or operationally tight, high efficiency can become a critical, vulnerable weakness.

Close to crisis

A society always runs close to possible crisis and collapse when it relies on a single provider of essential commodities. The hierarchical nature of the management of these commodities means that the job of managing them becomes more complex. Unfortunately, societies tend to evolve by developing hierarchies of control like this.

Ultimately one person has to embrace the complexity of the whole system, a task that sooner or later becomes impossible and therefore unworkable. A decentralised or distributed network structure for administering such a task would be more vigorous and manageable.

If we look around for a stable, vigorous and safe system built on a distributed network structure, we need look no further than the Internet. It has no central hub. It consists of many independent, yet interlinked nodes. If one node is knocked out, the operation of most if not all of the remaining nodes can continue as before.

Competition

From a lay perspective, and not being a mathematician, I look on complexity in a system as something that’s unpredictable, yet recognisable. The collapse of the Soviet Union occurred because of its high degree of complexity - true. My hunch tells me that, perhaps, the Soviet Union contained elements that actually reduced its degree of complexity. High complexity does not necessarily mean vulnerability.

For instance, I wouldn’t consider the existence of monopolies as being a feature of complex systems. Their existence is a feature of how societies have evolved over time. Monopolies comprise complicated engines around which whole systems depend. They represent vulnerable nodes within any system.

Oligopolies contribute to what are recognisable parts of complexity systems. As a group of nodes, they fit one of the key characteristics of a complexity system, that of being recursively elaborate. If one such node becomes extinct, the system can still function comfortably by using the other nodes.

Education as we know it

Might it be that the maintenance and preservation of future society is brought about by tending a degree of recursive elaborateness within that society? It’s what has kept education simmering for hundreds of years. Yet in many countries today, the signs are that education as we know it appears to be reaching a crisis point.

Is there something to be learnt here?

Lead by Example

It could be that the purpose of your life is only
to serve as a warning to others – Ashleigh Brilliant.

This month, The Learning Circuits Blog has the theme:

‘Presenting the Value of Social Media for Learning’.

Tony Karrer puts The Big Question:

How do I communicate the value of social
media as a learning tool to my organization?

The answer I have for him is, perhaps very slowly.

In the year 2000 I used Web1.0 technology in an attempt to emulate Web2.0. At that time I didn't know what Web2.0 was.

As senior teacher, I began designing web pages and developing elearning resources permitting learner interaction and feedback. I was labelled as a geek. This was despite the organisational approval, funding and planning time provided for me to engage in the development of elearning resources.

In 2002, as a full-time elearning teacher, this opinion of my role in using digital technology was confirmed by a newly appointed manager.

When she saw what I was doing using Web1.0/Web2.0 technology, she openly declared that she was not a geek. She affirmed that she could never embrace what I was practicing, for she did not want to be seen as a geek.

In 2007, a leading light on the staff created her blog especially, but not exclusively, for staff use and interaction. I was astonished that, from an organisation that supported hundreds of teaching staff, there were so few participants who entered into discussion on the blog.

In 2008, while working in the same organisation, I started a blog.

I discovered that many of my colleagues viewed this practice as a risky business. Some were still not sure what a blog was.

They had a vague idea that web pages, blogs and wikis, were all related in some way, but their exact function, usefulness and operational value were unclear to many and often viewed with suspicion. I have many colleagues who still find Web2.0 quite elusive.

In 2009, I'm pleased to share the blogosphere with several work colleagues ( 1 ), ( 2 ), ( 3 ), ( 4 ), ( 5 ), ( 6 ), ( 7 ) who actively maintain their blogs and post regularly.

Some have been blogging since early 2007. Whether anything I did had any influence on my colleagues to do likewise is purely a matter for conjecture. It’s been a long time.

But when it comes to communicating the value of social media as a learning tool, leading by example may be as good a way as any.

My colleagues and I have been writing learner reports this week. We follow convoluted procedures to ensure no parts are missed. The process is to provide effective feedback.

I reminded myself of the complexity of it all by sneaking a look at instructions that were circulating the office. The directions were clear, linear and easy to follow.

But I had a busy confusion going on in my head as I read them.
I was looking at a block of text that filled a page.

Balance of objectives

In the days when printed instruction was it, squeezing as much text and other information as possible onto a page met some objectives. There is merit in only one page of instruction. Selecting a smaller font-size was a trick I’d seen for ‘getting it all onto one page’.

But at that time, the Science and Art of developing easy-to-follow learner instruction was well known by experienced educators. They knew that ease-of-reading and learner-interest didn’t necessarily follow when information was packed so tightly into a page that you couldn’t put your finger down on bit of white space.

Extremists

White space became a prerequisite for a ‘good looking’ page of instruction. Born out of the look and colour of a blank sheet of plain A4, the ‘white space’ practice was carried, almost to extremes, by some writers and designers who actually shunned text – minimalists who’d trim even a brief, well written instruction.

Margins were widened, headers and footers were deepened.
Text quantity was limited per page.

Tricks and impressions

One trick often used, when no more text culling could be performed on an important block of text, was to emulate the impression of white space by selecting a very pale font colour.

In this way, otherwise unwanted text could be merged into the background. Of course, it defeated the purpose of providing instruction, for it was almost impossible to read.

No, I’m not knocking white space. It works well when used properly.
It lends itself to good web design and elearning resource design. The look and form of a blog post page can even be improved by applying it.

Techniques I’ve found that reduce the busy look of a page of text are:

short paragraphs – most readers find spaces between small blocks of text easier on the eye
double space around blocked text or images – an image can be aesthetically framed by a border of text-free space; the effect is more pleasing and restful on the eye
brief subheadings – these create chunks of text-free space by default.

You may have other techniques for improving the look of a page.

Why not share some of them here?

November

2009-11-07T17:56:00.001-08:00

It’s New Zealand’s last month of spring for 2009.

When I started blogging, one of the things I became attuned to was the sheer upside-downness of the rest of the world – compared to where I live, that is.

In the first few months, it was customary for me to wait overnight for the wave of blog comments to wash across a new post from countries other than those in the South Pacific, if it happened at all.

Most activity I observe on my blog takes place after daylight. Of course, there are always exceptions. There are nocturnal bloggers throughout the world and some who seem to be active 24/7!

Unsurprisingly, most people do not consider the time zones across the world when it comes to blogging. Last year I posted a Middle-earth time widget in my side-bar to help with this.

The academic year

There is as much disparity of alignment across the world when considering the education cycle. How many countries can enjoy an academic year that begins in January or early February and finishes in December? How many countries can claim that the (actual) year starts and finishes in summer?

The upside-downness prevails when reflecting on the seasons. While Canada was in summer New Zealand was steeped in mid-winter. Now, as Kiwiland warms towards summer, starting officially on 1 December, Britain chills into winter.

I receive regular communication from people overseas who are amused and surprised at the seasonal differences – till they think about the global cycles. It’s not something that can be easily summarised in a chart, for the seasons in each country progress and change.

video of northern hemisphere seasons (check out amazing videos)

November in New Zealand starts me dreaming of summer.

The hazy balmy days have come in fast,
A garden-loose late-blooming tulip yawns,
Limp petals soft from drooping roses cast,
And daisies flourish on the feathered lawns;
A cicada wakes from the nymphal sleep
Then sheds the fragile nut-brown pupal shell,
And so begins its steady skyward creep
To chant the long percussive choric spell;
The karo's darkened pods crack and expose
The cloying seed in clusters set to fall,
A blackbird swoops down keen to interpose
And sing his warbling chronicle to all;
With these the days I long for have begun,
The warm and lazy summer days of sun.

Remember, Remember

2009-11-05T13:15:00.000-08:00

Remember, remember,
The 5^th of November,
The gunpowder, treason and plot.
I see no reason
Why Gunpowder Treason
Should ever be forgot.

Tonight is Guy Fawkes Night in New Zealand – and it will be Guy Fawkes Night in several countries on this day – potentially a fun night for most children and adults.

The history of its origin has been well documented.

The scene is a cellar, directly underneath the House of Lords (Parliament) London, early in the morning of 5 November, 1605.

In a few hours, King James VI/I, the British Parliament and many dignitaries will be in attendance for the opening of Parliament. Having learnt of a rumour of a plot to blow up the Houses of Parliament, the King has ordered a check of the cellars to be executed this morning.

Guy (Guido) Fawkes is quietly leaving the cellar, having just completed his undertakings and last minute checks on dozens of barrels of gunpowder, laid all set to explode in a couple of hours. Fawkes is apprehended by the guards and the stockpile of gunpowder is discovered.

Further investigations reveal that Fawkes and several of his accomplices had attempted to destroy Parliament in what is now known as the Gunpowder Plot.

The outcome of the trial that ensued in January the following year brought Fawkes and his cohorts to the gallows. The King ordered that the event be celebrated by burning fires all over the kingdom.

And so a tradition began for a customary annual celebration.

What intrigues me is the fierce adherence to the Guy Fawkes tradition in New Zealand, a country that is now colonised by many nationalities. What is more intriguing is that a significant portion of people who celebrate ‘Guy Fawkes’ in that country have no knowledge of the origin of this almost pagan custom. Many simply refer to the celebration as Fireworks Night.

What is even more astonishing is that it’s nearly summer in New Zealand at this time of the year. Skyrockets and exploding firecrackers (or bangers) are already banned as they are a fire hazard. It’s not uncommon for dwellings (predominantly of wooden construction in NZ) to be burnt to the ground or large areas of bush and scrub to be razed over the ‘fireworks’ season. In its country of origin, Britain, the tradition takes place during winter when there is a low fire risk.

Legislation already restricts the sale of fireworks to a brief period in November. There have been several moves in recent years to ban the sale of fireworks for use at private celebrations in favour of public municipal firework displays.

My family watch the city display from our living room window. The whole sky is lit with pyrotechnics over a period of half an hour.

Interesting isn’t it, that the fun aspect of a bygone, almost forgotten celebration should so fiercely dictate how people choose to conduct themselves? For me, a shift to a suitable mid-winter date seems obvious as a first move towards safer fun for all.

Enjoy the fireworks!

The Ubiquitous Question – a reflection on learning

2009-10-31T04:54:00.001-07:00

“. . . unless you speak up... you will not be learning . . .”
Judy Jacob’s comment on Working With Online Learning Communities

I often wonder if our current education systems drive us to make invalid assumptions about how learning happens. I’m talking about educators here, not necessarily members of their learning communities.

Curious though it may seem, I learnt lots as I bumbled my way through high school. Not because I was especially able or bright.

I had an annoying knack of being outspoken when I couldn’t understand things. I hated not knowing what was going on. I asked questions.

The teaching moment

Fortunately, I had good teachers. They recognised the teaching moments that I presented to them – on a plate. I gained the respect of my teachers, probably solely because of this attribute of asking questions, for I certainly wasn’t a model student.

Good teachers admire learners who ask pertinent questions. It makes them feel wanted. Hence their intolerance of impertinence, I guess.

Asking a question offers a teacher the opportunity to fulfil that so-often-difficult-to-attain goal of the pedagogue. The goal is to teach relevantly. While it’s true that learners tend to engage more in learning when they interact during a ‘lesson’, I’m not so sure that speaking up or even asking a question is necessarily exclusive for learning to occur.

Questions and answers

One dated definition of education is ‘the ability to learn from a book’
(this implies the educated is still learning). You can’t ask a book a question. Today, we like our educated learners to learn from the Internet, using searches, networking and the like.

It’s presumed that these media permit the learner to ask questions. And the belief persists that asking a question – or even just speaking up – is so very necessary for learning to occur.

I’ve always thought of thinking as a stream of thought statements and questions, asked and possibly answered in the mind. My assumption is that a thinker asks questions of herself or himself and that’s what initiates further thinking.

Lying in bed, just awake, on a Saturday morning, having no plan pending for the unfolding day, my thoughts might go something like this:

“Shall I get up now? Or will I just lie here blissfully embalmed in the cosy bedding for half an hour?

I wonder what the weather’s like? Perhaps I could get the garden dug? Or maybe give the shed that coat of paint?

Ah, but isn’t it nice to lie in on a Saturday morning?”

This sort of discourse assists me to learn about how I feel. It can figure how the day that’s just beginning can become a part of my life. So yes, my assumption about asking questions still works. Even if I learn nothing of what’s happening outside my head, I can learn something about myself.

Assumptions on learning

So why do teachers assume that no learning happens without questions being asked? I think they are referring to what I call active questions, spoken or typed in a txt or email, or other such method of communication between two or more people. There is an assumption that the question has to be aired. But I am puzzled at how the idea fits with learning from a book.

It’s a point of view I’ve come across before, that of the lurker who never engages, never interacts and never asks questions. The inference is that the lurker never learns.

This is not the opinion of Nonnecke and Preece, who actually coined the phrase, Silent Participants for learners who lurk. They claim that learning can take place despite no participation from the learner. My own experience aligns with their research findings.

Etienne Wenger refers to community members who do not speak up as Legitimate Peripheral Participants. He recognises that learning happens even if the participation is only peripheral, that is to say the learners don't speak up.

Teaching, learning and assessment

Teachers are geared to assessment. Often they feel compelled to possess written evidence that a learner has reached an objective before they are convinced the objective has actually been learnt.

Assessment is forced participation on the part of the learner. Without engagement at the time of assessment, it could be construed that nothing can be achieved in an assessment test. Yet not achieving is hardy unequivocal evidence that learning hasn’t happened.

A principle upheld by designers of resources for distance learning is that if the student hasn’t been asked a question about a learning objective, and responds with the correct answer, the objective hasn’t been learnt. Prompting the learner to respond in this way gives the teacher an opportunity to record that learning has occurred. It tends to subscribe to the tick-box mentality, but at least it is a recordable event.

Questioning a way to learn

I’m not entirely opposed to the suggestion that questioning is a way to learn. Nor am I questioning the idea that learners will learn nothing if they don’t ask questions. My hunch is that questions are asked in the mind all the time. The trick of learning relevantly lies in asking the right questions.

Students who always have questions, and put them, will learn. They can ask them out loud or online, to a teacher or to another learner. Or they can ask them in their own mind. As long as learners keep asking questions, there will be answers given in return and they can learn from those. This is especially the case if learners know a thing or two about metacognition, even if they don't know the word.

Do learners have to ask their questions directly? To a teacher, for instance? Do you think learners will not learn unless they speak up?

Or can they learn without asking questions?

What’s your take on learning and participation?

Expert by Appointment – media and ICT

2009-10-29T19:28:00.000-07:00

We live in an age where ‘becoming an expert’ is just another turn of phrase. Despite research and the embracing of the results of this in several chapters of Gladwell’s Outliers, and in other similar books, expertise is looked on as being easily achievable.

You’ll be an expert in no time. You can pick it up as you go along.
In March 2007, MediaSnackers promoted these options in an advert, posted on YouTube, for a ‘research genius’ among other guru-types.
It indicates distinctly that “experience and qualifications are not essential” for any of the job offers.

I fit with the ideas that creativity, right attitude, an inspiring nature and professional mentality go a long way to assisting the activities of young up-and-coming pioneers. Certainly conformists and pessimists have their drawbacks, if innovation is where the job aspirations are at. I have no problem with all of those aspects of the brief.

The advertised positions are important to, and influential in contributing to the success of a new and growing organisation. The effectiveness of the training gurus and marketing managers in particular is key to this success. Yet there is nothing more likely to engender contempt in admirers or followers than the so-called expert who clearly demonstrates that he or she isn’t expert.

Or is this point of view outdated?

I support the youth of today. However, I wonder at the culture and attitude they may have picked up associated with the worth of experience and knowledge, and that they will carry these attitudes with them as they follow their careers. Is there something that I’m missing here?

Am I carrying the values and ideas of a bygone age?

The critical players certainly need technical know-how, marketing expertise, other skills and a basket of essential knowledge. Is it really the best way to launch our ships into future business space, building them as we go, having had no real experience in shipbuilding, resourcing or navigating? Am I so old-fashioned that I can’t see the potential that these new and innovative approaches have in reaching desired destinations?

Is it simply enough to sit back and marvel at the apparent successes of these approaches? I appeal for your assistance here, for I have been puzzled by these phenomena, and for many years now. It seems that they have become so numerous that I have no time to catch breath between instances of their occurrence.

What are your thoughts?

One Voice? A post for bloggers

2009-10-25T23:08:00.000-07:00

What sort of voice do you use when you write a blog post? Do you have an informal or personal tone to your writing? Or do you prefer the more formal structured approaches?

Perhaps you like to adjust your writing style to suit the topic. Many good writers do, but my observation has been that even some of the top bloggers use essentially a single voice in most of their writing.

Randy Olson’s book, Don’t Be Such A Scientist, slams the scientist for being too cerebral when it comes to writing for the lay reader. He explains that scientists are too literally minded, are poor story-tellers and in general tend to be unlikeable when they write about their passion, Science (check out Talk of the Nation interview).

Authorship

Bill Bryson is one of my favourite authors. He has written earnestly and engagingly on Science, and often. Just read a chapter or two from his book, A Short History of Nearly Everything, and you’ll know what I mean. But he’s not a scientist.

Bryson is a journalist. Yet even for me, twice a Science graduate, his ‘voice’ immediately captures my interest in the Science he writes about. He speaks as if he is talking with me, not talking directly at me.

Can bloggers learn a thing or two from successful writers like Bryson?
I think we can. But I also feel there’s more to it than just being able to write well in a specific style.

Genre

Knowing the appropriate genre to use, as well as how to apply it, is part-way to writers’ success. My literary friend and blogging colleague, Virginia Yonkers, agrees with this point of view.

Is there a single genre that is appropriate to writing blog posts?
Or should the genre be selected according to the topic of the post? Could genre be chosen to address a particular target group within the readership of the blog?

There are six genres that embrace most of the writing styles that bloggers may use:

poetry

Which would you select when you write your next post?

Binge Thinking

2009-10-20T22:54:00.001-07:00

This month, The Big Question on the Learning Circuits Blog is to do with New Presenter and Learner Methods and Skills.

Multitasking is now every presenter’s problem. Tony Karrer posits, “that there are things that presenters and learners should do to address this.”

Multitasking is binge thinking. It has the potential to distend the capacity of the brain so that normal thinking to do with any one task, including learning, becomes severely impaired. Tony says it all here.

Scott Flansburg is a supreme example of how a person can perform amazing calculative feats. He executes thinking skills that traditionally command extremely high concentration levels and all the thinking power that permits this. His unique ability to close down areas of the brain normally associated with other peripheral tasks makes him a matchless unitasker.

Thinking tires the brain

I am convinced that people often shut down areas of their brains automatically to make it easier to think. For instance, it is now known that when making decisions, the brain’s executive resources can be taxed to an extent that cognitive ability is considerably impaired. To prevent this happening in some situations, fast track routines are adopted.

Too much decision making over a short space of time literally tires the brain. Do people make decisions when attending a presentation? You bet they do, if they make a genuine attempt to learn from it.

PowerPoint and other potential vagaries

So why is it that when the audience is supposedly concentrating on the single task of learning, the presenter insists on giving them a series of tasks to perform synchronously? Cognitive overload associated with the misuse of PowerPoint has become a talking point. It is an issue because it’s real.

Learners well know that when the presenter reads the text from a PowerPoint slide, the best thing to do is to shut the eyes and listen.

So why is the text on the PowerPoint slide in the first place? For the presenter? No! It’s there because the presenter knows nothing about cognitive overload. A better way is for the presenter to shut up and let the learner do his or her own reading.

Take note

Tony refers to backchannel as a distraction for the presenter. I’m not surprised he finds it distracting. It is nevertheless an inevitable activity if learners are engaged in taking notes, by whatever means they use.

Through years at school, university and attending hundreds of seminars since then, I have learnt to take notes while giving nearly full attention to a presentation. It’s one multitasking practice that I’m good at. But not everyone has this skill.

What I’ve found often helps is if the presenter provides printed notes on the PowerPoint bullets – before the presentation. This frees up the brain when it comes to taking notes. I just write my additional notes on the PowerPoint printout.

Cognitive engagement

But there is another aspect to presentation – and that is of intent.

What does the presenter really want the learner to take away from the experience? If the seminar has a sales pitch, it may be better not to dwell too much on the facts and details that a learner may take away.

Research has shown that the verbal content of a presentation, whether in speech or text, is only a small part of the total message conveyed to the attendee. How often has a conference goer raved about a ‘keynote’, reporting that the best thing about the presentation was its entertainment value?

What if the presentation was entirely lacking in entertainment, yet the same factual information was presented? Herein may lie a pedagogical message.

Entertainment provides two important features to the learner. It provides the necessary breaks between learning tasks and prevents the possible onset of cognitive overload brought on through multitasking. It also adds interest and factual significance by association.

The web image and how it operates are often misunderstood. Hypertext Mark-up Language, more commonly known as html, was invented to process text size, shape and colour on the Web.

When it was realised that html and related codes could be used to handle images, the Internet became a viable commercial medium.

The pixel

Close examination of images, on screen or when printed, shows that they are made up of many coloured spots, dots or squares. These are called pixels. The word pixel (picture-element pix-el) can also refer to the digital information associated directly with the coloured spot, held on a computer or transferred in a download.

What can be confusing is that ‘pixel’ is also used when referring to the smallest element that displays a single spot of coloured light on a monitor or TV screen. These tiny elements are permanent parts of the screen hardware. They are not the same as the pixels in the image that effect the display.

Image file size

A popular misconception is that the dimensions of an image, as it appears on the screen, are to do with the space the image occupies in computer memory or on disk. The term ‘image size’ can also be misleading, though this term refers to the capacity of an image to occupy space in computer memory or on disk. It’s more usual to refer to it as the image ‘file size’, measured in kilobytes or megabytes.

Image dimension

The physical size of an image on the screen is another property that’s often misinterpreted or misunderstood. Images are really two dimensional things. Despite tricks of design, it’s not possible to have an image that is triangular, round or any shape other than rectangular, unless there is some distortional fault with the printer or screen.

An image has a height and a width, which make it easy to define its dimensions. These two lengths are measured in pixels, but can also be given in mm or cm. Though variation tends to be slight, the physical accuracy of image dimensions expressed in metric units varies with the equipment used to display the image.

Optimising image file size

Digital cameras can take pictures with file sizes of several megabytes. There has to be literally tens of millions of pixels in the files so that high quality pictures can be obtained. The fineness of detail that’s displayed from such images is particularly useful if they are to be printed in a large format or viewed with full screen in a picture viewer.

Images show how pixelation increases when file size is reduced

For most web purposes, however, image files of that order of size and quality are not necessary. What’s more, huge image files can occupy valuable resource space on the host site and cause unreasonably long upload or download times.

It’s often prudent to use some form of quality reduction. Adjusting the content of the image so that it gives a satisfactory display with a smaller file size is called optimisation, or optimising the image.

Most image hosting websites, including blogs and social network sites, optimise images automatically. If the images are satisfactorily optimised before uploading to the host site, it can save time, and in some instances be a cost saving too. Sue Waters’ excellent post on Uploading Photos From Digital Cameras Into Blog Posts gives great instruction on using several free packages for doing this.

Bitmapped images

The simplest way of arranging image information in a digital file is when each pixel carries its own information, as in a bitmap. This can be an inefficient way of packing image information, however, so bitmapped images tend to have larger file sizes than other image types of the same quality.

Compressed formats

JPEG, PNG or GIF type images use different systems of file compression. Pixel information that is duplicated, as can happen when the same colours are used over large areas of an image, is stored in a formula within the image file. The result is a smaller file size than that of the equivalent bitmapped file with the same image quality.

One advantage of the GIF compressed file type is that it can also include information on how separate image frames can be constructed. A special type of GIF file can display a cyclical series of frames like a looped movie – the so-called animated GIF.

Vector graphics

The introduction of vector graphic creation tools, such as Adobe Flash Writer, has brought new dimensions to image design and the way images can be displayed. Standard bitmapped images and related image types tend to break up, or pixelate, when enlarged on the screen.

What happens on display is that the information held in the image file is stretched over a larger area than was intended. The result is an image that appears to lose detail and sharpness and may look as if it is made up of chunks of colour, which is precisely how it is composed.

A vector image, on the other hand, does not lose its sharpness or detail when it is enlarged on the screen, simply because there are no pixels in its image construction. True vector images tend to be limited to line diagrams and ones with solid areas of colour, however, and cannot be created from digital camera image files.

“What we must do now is step back from self interest and let common interest prevail.” – United Nations Framework Convention on Climate Change, Executive Secretary, Yvo de Boer, at the Closing Press Briefing, Bangkok Climate Change Talks, 9 October, 2009.

The earth is a ball of rocky material, partly covered by water and enclosed in a capsule of gas called the atmosphere. As it orbits the sun, it is bathed in a stream of radiant energy. Some of this energy is absorbed by the earth as heat.

If absorption was the only process, the earth’s temperature would rise quickly, the water would boil off and its rocky surface would melt. Fortunately, this doesn’t happen. The earth reflects some radiation away from itself. It also radiates energy out to space. Artificial satellites can take photographs of the earth by the reflected and radiated energy.

There is a balance between energy the earth receives from the sun over time and energy it reflects and radiates. In an ideal world, the earth's overall temperature would be stable.

A hothouse

Theory has it that some factors enhance the absorption of the sun’s energy. One idea is that particular gases in the atmosphere can act like the glass of a greenhouse, trapping heat energy. It is believed that gases like these, known as greenhouse gases, can cause the temperature of the earth’s atmosphere to rise.

Temperature shifts caused in this way are not necessarily evenly distributed across the globe. Some parts of the globe may even experience a lowering in the average temperature. Such is the complex nature of the earth’s atmosphere.

Some earth history

I find it fascinating that a beautiful green savanna, over a period of 6000 years, became the wasteland we now know as the Sahara Dessert.

Equally as curious is the desertion of a Neolithic settlement on Orkney 4500 years ago. Supposition is that a fall in temperature in the earth’s atmosphere, and ultimately a brutal storm, drove the settlers from their homes at Skara Brae in Orkney.

About 1500 years ago, Britain was invaded by the Saxons. One theory for the invasion is that it happened when Saxon homelands were being flooded by rising seas caused through climate change. The Saxons were looking for land that was less likely to be threatened by rising sea levels.

Earth’s varying climate

Despite the blame for climate change being levelled at the production of greenhouse gases by humans, it appears that significant climate variation is part of what has always happened.

All the above happenings took place during recorded history and are similar to situations that have arisen in other parts of the world today. They came about when human contribution was comparatively insignificant.

Is it possible that these events would have occurred even if there had been no human contribution? Is it also possible that human intervention may have little effect on future climate change?

Faithful representation

There is a deal of misrepresentation about climate variation and its consequences. Unfortunately, the cover of the most recent United Nations Environmental Programme Report is a typical example of this. Not only is the representation flawed as to what global warming is likely to do to the surface of the planet, it also conveys a completely erroneous view of possible consequences to humankind.

There is a need for faithful representation of what’s happening to our planet. Attempts to provide this are likely to be subjective and are often prejudiced politically.

Reasoned approaches

The Kyoto Protocol was adopted in December 1997, “aimed at combating global warming. The Protocol establishes legally binding commitment for the reduction of four greenhouse gases (carbon dioxide, methane, nitrous oxide, sulphur hexafluoride), and two groups of gases (hydrofluorocarbons and perfluorocarbons) . . . ”

Yvo de Boer expressed dismay at the current moves to “kill the Kyoto Protocol . . . by a number of developing countries . . . while at the same time there is not even something better in sight or on offer”.

The Kyoto Protocol attempts to take charge of those factors that may contribute to global warming and that are within human control. It represents reasoned approaches to responsibilities to the future of humankind and of other living creatures on this planet.

Global responsibility

For as much as change happening within the earth’s atmosphere is inevitable, humans apparently continue to make ruinous contributions that may well exacerbate a dangerous climatic situation.

Should we strive to deal with likely contributing factors that are within our reach to control? Or do we simply leave it to ‘Mother Earth’ to take care of all this?

The world’s nations are being alerted to the possible consequences of ignoring what appear to be clear signals from the planet. Talks are being held across the globe. My sincere hope is that nations throughout the world will adopt a unified approach to dangerous climate problems facing the planet – that they reaffirm the Kyoto Protocol and make commitments to take concerted action for the common good.

A School of the Future?

2009-10-09T22:11:00.001-07:00

I believe that education in the future may not be best achieved in schools. However, this post summarises what I think should be the components of an ideal school of the future. It is not a summary of my idea of where education should be going, or how it should be obtained.

Tania Sheko is hosting the 'Green Pen Society' (GPS) writers' club over at Brave New World, for Paul Cornies at quoteflections.

Her topic for October is:

What would your ideal school look like?
Design the school of the future – but do it now!

How could I resist a topic like that?

Having taught in many different schools, and in different countries, I’ve gathered hunches, likes, dislikes and theories that can help me with ideas for the design of the ideal school of the future. It is a difficult task.

A secondary school

The ‘ideal school’ is forever a mythical artefact, for by definition a school has to meet the needs of many. No school can serve completely all learners all of the time.

As well, its situational constraints must necessarily govern the functions that it can deliver and needs to provide.

My ideal school would be a secondary school with a roll of learners from say, ages 12 to 18 years. It will prepare all learners for further learning. It will provide pathways to employment for those learners who, for whatever reason, leave the school to seek employment before having completed all available education levels within the school.

School providers and authorities

Assuming that the school is capable of serving all situational needs of its learners, the first requisite must be that it is affordable.

Fine education costs. We should all know that by now. If it results in overspending, however, then ultimately the future availability of good education within the school will suffer.

For as much as the ideal resources, pedagogies and learning environments are important, and to whatever specification these may adhere to, if they cannot be sustained, or are not seen to be sustainable by the providing authority, they cannot form the components of my ideal school.

Governance

My school will have experienced governance, administered by a necessary board of trustees who genuinely have the future situational needs of the learners at heart. To do this, the governance must have a vision for the big picture of what education should bring to learners in the 21^st century.

Management

Counterpart to governance, the school’s management will likewise have an eagerness to use such teaching structures within the school. There will be commitment to use resources, pedagogies and learning environments that foster teaching and learning that best suit the future needs of learners.

The whole picture

As boring as all of the above may seem, without them no ideal school will succeed. They are integral parts of the whole picture.

The school will have classrooms, workshops, laboratories, a library, recreational areas and halls as fit the needs of its composition. If at all possible, it will have a roll of about 550 learners. From experience this size appears to find the optimum fit when it comes to timetabling and managing resources and courses, especially for the senior learners within the school.

Allocation of classes should aim at an optimum size of 24 learners and a ceiling of 28, with some flexibility within reason. This is an ideal school, so depending on the needs of individual learners there may be a call for smaller class sizes for some groups.

The best fit

I use the term ‘best fit’ on purpose here. Education is a complex thing.
I believe it is impossible to provide every factor that makes for good education, simply because of its complexity. Like other complex systems, however, it should be possible to make a best fit for ongoing situations, within and external to the school, that will be neither static nor exist in a state of equilibrium.

To this end, the learning resources provided in the school must also be capable of adapting rapidly to current changes. Methods used for delivering resources to teachers and learners must likewise be capable of evolving and adapting to suit emergent themes that will trace and follow the development of the immediate society.

A blended learning approach that best utilises the appropriate methods for teaching and learning to fit the learner and topic will be recognised by teachers and teacher management.

Elearning platforms

If an elearning platform must be established within the school, it should be open source. The expense of any commercial elearning platform can so easily preclude further development in platforms other than open source ones, so it is best to adopt open source from the beginning. This frees up finance, much needed within the school, for non-negotiable expenses and specific resources that may have no alternatives.

A stable, generic learner management system should embrace any learning content management system chosen to meet the needs of the school’s resource requirements. Too easily, the maintenance expenses on such systems can get out of hand, ending up like the tail wagging the dog. This is why good governance working closely with good management within the school is so important.

I’m talking in ideal big picture stuff here and purposely not mentioning commercial brands of hardware or software. A school that’s capable of adapting through emerging requirements should not be tied to any specific commercial provider or commodity brand.

And this brings me to a conclusion. The ideal school will need to be mobile, as the movement of a flock of birds. It will shift with the elements, yet remain intact as it moves bodily to meet the varying needs of the ever-changing learners within it.
