Art and the Artist

Miguel Guhlin quotes a person asking, " Is it even necessary for an art classroom to have all of the technological advancements of the modern age?" and replies, in part, "Imagine what would have happened if The Impressionists--did I mention I hate art?--hadn't been able to share their ideas with others."

I do not address his point that "The fact is, it's changing how people interact at the most fundamental levels OUTSIDE the either use it, or you don't. " - with which I am in fundamental agreement. This is about the rest of it.

The question also demonstrates a surprising lack of knowledge about art as a discipline. Art is often the first of all the disciplines to embrace a new technology. Usually, entire new disciplines evolve out of this.

Examples? Artists began using imaging technologies very early on, inventing photography, which evolved (through confluence with another art, drama) into motion pictures and television.

Artists experimented with electronic sound very early on, developing instruments like the Moog synthesizer, eventually changing the entire world of music.

Artists began using the printing process as soon as it was invented - arguably influencing the development of the Gutenberg press. Continued use of printing technologies led to the discipline of graphic design. Design software was one of the first killer applications for computers (remember Quark?) which led to things like SGML, the direct forerunner of HTML and the web.

Performance artists were among the first to catch on to the communicative capacities of the web, crating such exhibits as 'flash mobs' and other guerrilla theater pieces. These were a direct forerunner not only of social networking but also of political organization from Seattle to Howard Dean to Ron Paul and Barak Obama.

Finally - regarding your comment that you "hate art" - it sounds to me like somebody has spoiled 'art' for you some time in the past. That's too bad.

'Art' isn't a matter of walking around in galleries looking at static paintings going, 'ah, the impressionists' and nodding appreciatively at paintings you don't like.

Art - properly so-called - is totally about communication, which means that appreciation (*genuine* appreciation) is an important part of the work. It the work doesn't speak to you, if you don't like it then the work has in a certain sense failed (not in the evaluative sense (our culture is so infused with judging it's almost impossible to get away from that sort of language) but in the sense in which a person speaking French has failed to communicate with you if you speak only English.

Where 'art' becomes something that people 'hate' is when artists (and their admirers) become dishonest and pretentious. I once wrote an article, in my pre-internet days (I'll post it one day), 'On Artistic Criticism', the point of which was to respond to an artist who, after spilling some paint on his sculpture, tried to explain it as 'the randomness of the cosmos'. It was totally dishonest and simply made the work unintelligible to viewers.

Artistic criticism - like literary criticism - is full of this sort of pseudo-interpretation. They are like that character on MAD TV who, when called on to translate languages, interprets everything as "OK hot dog!" Understanding art doesn't require seeing the world through an art critic's eyes (good thing, too).

Instead of seeing art as something that is done to you, forcing you to respond to it appropriately (like a stuffy waiter at a French restaurant that sneers at your misunderstanding of 'escargot' on the menu), art becomes relevant when you take control of it and make it something you own and that belongs to you.

A work of art - *any* work of art, whether displayed in a museum, in your home, or on your web page - becomes, on this account, part of *your* vocabulary. It means what you want it to mean. It says what you want it to say.

You can use any of the arts - painting, photography, video, music, design - in any way you want to add colour, texture and depth of meaning to what you are writing. It doesn't even matter if you can't say what that element of meaning is - meaning is often ineffable, no matter what the critics say. If the artistic work 'goes with' whatever you are saying, that's fine.

In my view, it is important that communicators do this because there are ways in which words alone do not express what they mean. It's like Barak Obama's speech - you can read the words, and nod along, or listen to the words - the stress, the inflection, the pauses - and 'get it'. Art - properly so-called - is the stress, the inflection, the pauses of our lives.

Most probably, 'art' class probably never taught you that. It was probably about being able to identify impressionists on command (I remember studying paintings for a game show called 'Reach for the Top' - what a way to wreck a good painting).

Museums often do a lot of injustice to art (not always, though - it really depends on the curator) by taking one piece of a complex message and displaying it as a single artifact. It's as though you were presented with the word 'eglise' and expected to reflect on its sense and relevance, in isolation from any context in which it might be used.

To me (and you can see this in my photographs) understanding art is like walking through the streets of another culture, my use of art being my way of saying back to them, *this* is what I saw, and *this* is how I felt. It is a conversation - but not in words, not evn of something that could be expressed in words.

Look at my photos of Medellin. Can you see the conversation there? Can you see the Colombians and I engaging in this dialogue, the people of the city trying to convey their spirit through their art, and me responding in kind, expressing my appreciation, my understanding, my thoughts.

So long as 'art' remains something that hangs on a wall, this conversation can never happen. But the minute you make a piece of art your own, though its use in your own vocabulary of life, art becomes meaningful, not obscure and stuffy, but personal and alive.

Economics in a DRM-Free World

After my previous post, Doug Johnson asked me to explain the economic model of a DRM-free world. This has been done by others on numerous occasions, so what follows should only be thought of as a summary.

Today, the demand that someone (not necessarily the artist) be compensated for the creative act is driving the demand for digital rights management. Because it is today so easy to make copies of content, the idea is that any access to content must be compensated. Otherwise, we are told, the creator (or, more accurately, the rights holder) will not be rewarded.

But we have had free content since time immemorial. Not always in the form of television, obviously, but from the days the first stories were told around the campfire and the days the first paintings were drawn on the walls of caves, listeners and viewers could access that content for free.

It is important to recognize this. It is important to see that free access to content has, though history, been the rule, not the exception. That the commodification of content, that the charging of access fees, subscriptions, or some other form of tariff, is a recent invention for almost all forms of content.

Yet, somehow, through history, artists and authors and musicians managed to ply their trade. How was this possible? It was rarely through sale of recordings or reproductions. Here are some ways authors, artists and musicians can support bthemselves in a post-DRM world.

1. Sale of Original Works

The best examples of this practice are found in the visual arts - paining and sculpture, especially. Even though it is possible to create copies, the original cannot be recreated. This makes it rare, and hence, valuable. The same approach may be used in writing; witness J.K. Rowling's The Tales of Beedle the Bard, handwritten and bound, which sold for £1.95 million at a Sotheby’s auction.

Indeed, it is by selling original works that most craftsmen and artisans make their livings. We see at the Craft Fair at the local park very year everything from photographs to candle holders to wood shelves to maple syrup being sold by local merchants. And people who lay bricks, build houses, make hamburgers, and grow wheat also profit by the sale of original products. This, indeed, is the dominant form of commerce in society, one that artists would do well to consider.

2. The Sale of Services

While the musician does not frequently sell an original work, the musician is almost unique among the artists in his or her ability to offer a performance (though you can also watch painters performing). As we are frequently told, musicians typically make more money performing than through CD sales. That is why Canadian musicians have split from the recording industry.

Most people in the world make their livings from performing services. Photographs take photos by request, artists paint portraits, authors write news articles and obituaries and greeting card poems. Waiters bring us our food, receptionists greet people and ask them to sit in the waiting room, call centre staff answer questions and provide advice. The people who perform services rarely, if ever, retain rights to the work they have performed. Artists and other creative talents should consider that this might be good enough for them as well.

3. Selling Sponsorships

This is the reason we have free access to content on television and radio. Today we know this under the more generic name of 'advertising', but the sale of sponsorhips has a wide variety of models, everything from the restrained sponsorship messages on public broadcasting to the blazoning of company logos on sports jerseys and racing cars.

Advertising has always been (and remains) the major source of revenue for newspapers - so much so that even the venerable New York Times has abandoned its paid content model in order to lure more readers to view its advertisements.

Advertisers seek implied credibility by association with quality or entertaining content. So advertising is not suitable for all types of content, of course (though you would never know by the way it is relentlessly pursued). Advertising is probably inappropriate for educational content. But for many artists - especially those in video and entertainment - advertising can help pay the bills.

4. Obtaining Patronage

Mozart was employed as a court musician by the ruler of Salzburg Prince-Archbishop Hieronymus Colloredo. Michelangelo worked under the patronage of Pope Julius II. Even Ranier Maria Rilke was supported for a time by the patronage of Ludwig Wittgenstein. The glory days of patronage may have passed us by, but it remains the primary means of income for many creative workers.

My own work, for example, is funded by the Government of Canada, as I am employed by the National Research Council, an appointment that may be seen as a sort of patronage. Foundations routinely support authors and artists and others. IBM has its fellows program. Japan has its living treasures program.

5. Work for Hire

If it's good enough for tens of thousands of university professors, it should be good enough for artists as well. Professors are not compensated for the articles they write, nor do they receive income for reviewing publications. Even if they write textbooks, their earnings are minor compared to the salaries they receive for teaching and research.

The vast majority of crative workers - authors, artists, even musicians - receive no royalties or other income from their creative works. These rights are retained by their employers - newspapers, magazines, advertising agencies, and myriad other businesses and agencies. This content is, in turn, used to make money by any of the other means described in this article.

6. Bundling

Vendors compensate artists for creating or contributing content to be distributed with their products.

Prince recently created a sensation when he released his latest album for free as an insert inside the Daily Mail. This is a distribution method writers of open source software will recognize instantly, as almost everything written under the GPL eventually winds up on a magazine CD as a giveaway. Starbucks, meanwhile, has been giving away free music to coffee patrons. Even McDonald's is giving songs away with meals.

It's a bit harder to give away writing and art - there's less demand - but nonetheless very practical and useful add-ons can be given away with food, hardware, indeed, any sort of product. This will be a significant source of income for learning materials, as vendors seek to stimulate a demand for their product by teaching people about it (the book on types of coffee the vendor in McEwan Hall once loaned me made me an affectionado for life).

7. Loss Leaders and Marketing

When Ben Goodger was hired by Google, his previous position had been unpaid: he was one of the lead developers for Firefox. Like many programmers, he made his name writing open source software. The work he did became a a calling card or an advertisement for his work.

If we look around the education boogosphere we see numerous examples of the same phenomenon. Jay Cross, Harold Jarche and Nancy White all offer consulting services - and they also make their views known for free on their weblogs. Their free public writings are the best publicity they could hope for as they can clearly demonstrate their talents to others.

8. Helping People Being Creative

I call it the 'butterfly thesis'. It goes like this: people everywhere in the world decorate their homes with wooden butterflies. They are not paid for this act of creativity; quite the contrary, they actually pay for the privilege. But they want btheir houses to look nice.

In a similar manner, the vast bulk of the content on Flickr was produced not by people who wanted to make money from their art but by people who were creative and simply wanted to share.

This becomes a business model when people realize that our desire to share is itself a powerful force in society. From the scrapbooking store down the road to the photography shop to Google Video and YouTube, people have been making a living helping other people be creative.


The idea that you have to restrict access to make money is a fallacy. None of these techniques require payments or subscriptions or other fees, nor do they require digital rights management or any sort of access control at all. Indeed, many of them depend on free and open access.

Shifting Morality

Doug Johnson writes, "I am not sure that these kids are less moral - only differently moral."

I think you may also want to examine how publishers and their supporters are changing (or trying to change) the concept of 'morality'. Let me highlight some areas:

- the 'doctrine of first sale' is in the process of being repealed. What this doctrine states is that, if you buy something, you own it outright. You can, in turn, lend it, sell it, use it as a doorstop, whatever you want. Increasingly, manufacturers are retaining rights - not just regarding copying, but where something is used, how it is used, for what purpose it is used, and more. It's fair enough for them to try, but how does it become *immoral* for people to defen their rights under the doctrine of first sale?

- the doctrine of 'fair use' or 'fair dealing'. It has long been understood that a creator's rights under copyright are not absolute. In particular, under 'fair use' (or 'fair dealing' in Canada) we have historically had the right to copy a small portion of the work to use when citing, referencing, criticizing, parodying, or teaching. Publishers simply refuse to respect this doctrine - try publishing work with citations allowed under fair use but explicitly cleared by the other publisher. Or try showing a logo in a video without blurring it our. Meanwhile, DRM and similar technology makes fair use impossible. And such use, we are told, is immoral. How so now?

- the distinction between personal use and commercial use - we have had a longstanding understanding that restrictions on certain commercial activities - making copies onto blank media, for example - are perfectly legal in the noncomnmercial domain. That sharing copies among friends is a fundamentally different type of activity. In Canada, moreover, the government collects royalties on blank media, distributed to content providers, in explicit recognition of such activities. How, then, do they become immoral?

- the idea of 'free access' - from time immemorial, we have grown up believing that performances of various media are free to the viewer or listener. From listening to musicians play on the street or in bars, to watching TV or listening to the radio, to reading books in the library or billboards on the wall, if the media was available, then we could access it for free. There was never a *way* to act immorally in this regard. But now we are required to 'avert our eyes' - to not view, to not listen, to not download - in certain cases (and somehow, to magically know what those cases are). Why is this? Why is it OK to listen to a song for free on the radio but not listen to the very same song on the internet? How does the one behaviour remain moral but the other, somehow, become immoral?

- the doctrine of 'sharing' - as children we were told that sharing is good. And that when there are things that everybody can use - parks, roads, museums, culture - these are good as well. But more and more, we are being told that sharing is bad, and that everything must be owned by some person, who in turn has a 'right' to be compensated. How so? What gave *this* person, rather than the thousands of generations before him that nurtured the concept or the idea, ownership? How did sharing, always a virtue, become *bad*?

You get the idea. Children do not have some fundamentally different morality. Rather, they see - while adults, for some reason, are blind - that the game is shifting, that some very self-centered and greedy people are trying to change the rules. The children - who have no stake in this sudden 'ownership society' - are not fooled. We shouldn't be either.

Free Learning and Control Learning: On the So-Called Failure of Constructivist, Discovery, Problem-Based, Experiential, and Inquiry-Based Teaching

Text of my presentation to SURF Education Days, 13 November 2007, Utrecht, the Netherlands. Slides, audio and video are also available.

1. Introduction

I don’t have fancy slides today. I don’t have nice pictures or anything like that. I’ve spent some time over the last few days looking at a paper by Paul Kirschner, John Sweller and Richard E. Clark, which describes the “failure of constructivist discovery problem-based experiential and inquiry based teaching.”

For those of you who are familiar with my work you’ll know that a great deal of the work that I’ve done is constructivist discovery problem-based experiential inquiry based teaching. And so this sort of paper is published in Educational Psychologist, which I guess is an important journal. It’s been widely cited.

This sort of paper and the criticisms associated with that sort of paper raise questions. I do work in educational theory and I also do work in software development and I’m never completely sure that I’m doing the right thing. I raise questions. Is the work grounded in research? Is this really the way learning happens? And so I question myself and I question myself not just because it’s a good thing to do, but just because I’m not positive.

So I worry when I see papers like this. I worry that maybe the foundations of the work that I and other people are doing is not well-grounded, but then I look at a paper like this and I realize that what really needs to be done is that these arguments need to be drawn out. They need to be made explicit and it needs to be shown very clearly and not ambiguously why these are not good arguments and that is going to be my task today.

And for you who are listening to this task today, what you’ll be able to take away from this, I believe, is, first of all, an outline an idea of the theory of learning that underlies learning with blogs and wikis and other web 2.0 technologies, but also, more importantly, a way to respond to people who think that instructional technology and the use of the Internet in online learning ought to be nothing more than the presentation of instructions to students telling them what to do. That is control learning. That is the old way of learning. The web way of learning, Web 2.0 learning, is the new way. It is free learning and that is what I advocate.

2. Connectivism (Free Learning)

Sometimes this theory is known under the heading of connectivism. Connectivism is a name that was coined originally by George Siemens. Connectivism is essentially, and this is my take on it not necessarily George’s, the theory that knowledge and learning can be described and explained using network principals.

Now what do I mean by that? What I mean is: knowledge itself, to know something, is to be organized in a certain way, to have a certain pattern of connectivity in the mind, a certain neural connection in the mind. To learn on that theory is therefore to acquire that pattern of organization. To learn is therefore not to have things pushed in your head but to grow and to develop in a certain way and specifically to grow and develop in such a way that you are able to recognize patterns in the environment.

Connectivist learning theory, therefore, is based on the theory of how networks learn, that is to say, how networks grow, how networks develop, how networks form structures of connections between neurons. There are four major ways in which networks grow. And I’m not going to say that these are the only ways, these are all the ways, that this is the definitive statement. But these are ways that we have observed through history that networks grow.

One way is simple Hebbian association. What that means is that if two neurons fire at the same time and don’t fire at the same time, a connection tends to be drawn between them. That’s it. Very simple!

The second way is accidental association. If two neurons are beside each other a connection tends to join them.

The third way connections are formed is back propagation and this comes from the theory of connectionism in the field of computer science. The networks form their connection and then feedback is sent into the network according to the output that the network produces. If the network produces good output the connection will be reinforced. If the connection produces bad output the connection will be broken.

And then finally, Boltzmann learning, which is a theory based on thermodynamics, which says essentially that connections will tend to form at the most stable configuration. If you think of it as like throwing a stone into a pond, the water will settle out. Well connection in brains work in much the same way, according to this theory, and the brain settles out.

The main thing to understand here is that connectivist learning theory is about how connections form in the brain, and for that matter how connections form in networks generally. Because connectivists talk about not simply networks in the brain, they also talk about learning networks in society at large, networks of people in society who are connected to each other. The two theories work out to be two parts of the same theory.

In connectivist pedagogy, therefore, to teach is to model and demonstrate. To teach is to present experiences to people so that they can begin to form these connections in their mind. And then to learn is to actively form these connections by practicing, by repetition, and by reflecting on that practice.

Both of these imply what might be called participation in an authentic community of practice. The idea here is that to learn is to put oneself in a situation where you are practicing in the way that whatever discipline you are in is practicing. For example, you learn physics by doing physics. You learn how to take care of forests by going to a forest.

The role of the teacher in this model is to practice one’s work in an open manner. This has been a challenge, I think, for pretty much all of society, but the idea here is that instead of doing your work in secret in back rooms without being open about what you do, you do your work in an open and transparent manner so that people can see what you’re doing.

In preparation for this talk, for example, I created a summary of the Kirschner, Sweller and Clark paper and I put that on my Website and I collected notes from other people who wrote about this paper and I put it on the website and what I wanted people to see is how I go about assembling my thoughts in order to prepare for a talk like this.

To work, on this theory, is to engage in a community. Most of us, when we do our work, in whatever profession, don’t do it simply all by ourselves. We are involved in a community of practice. We have shared ways of doing things. We have a shared vocabulary, a shared understanding of what constitutes success, a shared understanding of how we test for that success. And it’s to be openly reflective to think about what we’re doing in this community and to think about whether it is the best way to do it, why we’re doing the things that we’re doing.

In this model the role of the learner is to themselves in some sort of environment like this. It may be the actual community of practice itself, which is what I recommend, or it may be a simulation of that community, perhaps a role playing game, perhaps electronic performance support systems, perhaps the actual community of practice itself. You can imagine all the different ways a learner can place themselves into one of those communities of practice. It is to observe the way people who are successful in that practice actually conduct their practice and it is to be reflective to engage in conversations about that practice.

You can see why Web 2.0 and Internet technologies like blogging and wikis and things like social networks play such an important role in these theories. These are technologies that make this sort of activity possible. These are technologies that make it possible for a person to practice their discipline in an open manner. These are technologies that make it possible for a community of practice to develop on a worldwide basis connecting people from many different countries together. They make it possible for the learner to observe experts, to interact with experts, and to learn by doing.

3. Instructivism (Control Learning)

The other view of the world is known as, well, there are different names for it, but I will call it control learning or instructivism, and it is the approach that’s characterized in the Kirschner, Sweller, and Clark’s paper.

It’s a model of learning, and especially on line learning, that is what we might call traditional on line learning. What this learning is, is learning based in the theory of learning objects and based in the theory of the learning management system.

And the model here is that our on line learning environments basically emulate the practices and the processes of the content in a traditional classroom. Learning objects contain content in the core, and pedagogy that is wrapped around that content and the idea of this traditional learning is that the content must be explicitly instructional. The content must actually guide the student or the learner through a series of instructional steps.

The idea of learning object theory is that the learning object needs to have, for example, things like learning objectives. It needs to have guided practice. It needs to have assessment of some sort.

The basis for this theory, the basis for this approach and where it is practiced the most is in environments like the U. S. military where the Sharable Courseware Object Model or SCORM was developed. And SCORM is basically a model of personal learning where you go step by step by step through the learning manual and you follow the instructions that they tell you to follow, you do what they tell you to do and that is what is supposed to produce learning.

The learning management system and we’re familiar with the learning management system, we’re familiar with systems like blackboard, for example, or even open source systems like Moodle and Sakai. The intention of these programs is to present this material step by step by step.

In the introduction (to this talk) the Buntine oration that I gave in Perth is mentioned. In that talk, there are three major locuses or loci of control; three places in which control of the learning process, control of the learning content is exerted in this traditional picture.

One is in content packaging. And if you think about content packaging what content packaging is, is you take a bunch of learning objects, put them all together, put a wrapper around them and then you compress them with a zip archive or something like that, thereby making them useless even to a browser. Content packaging is a picture of learning as a package that you put on a shelf like a book in a library.

Federated search, second. Federated search is not like Google. Federated search, which is the approach that is recommended by the people who created SCORM by advanced distributed learning is a mechanism where when you search you search this library, this library, this library, and this library and that’s it. You search only from recognized authoritative sources who have ‘the knowledge’, whatever that happens to be, authoritative sources, I guess like Educational Psychologist, the journal.

And then, third, learning design, which is a third major component, which actually has its origins here in the Netherlands with Rob Koper’s educational modeling language or EML is a mechanism for stepping you through the presentation of learning materials. Now Learning Design will put you in roles and Learning Design will branch and present different materials in different circumstances, but it’s still that theory of presenting material, presenting material, presenting material, and the theory behind that is if you are told what to do you will learn. And that’s the basics, the basis of instructivism.

4. The Argument

And so now I turn to the paper, that I intend to criticize in this talk; why minimal guidance during instruction does not work and the corollary of that is why maximal guidance does work.

And what the authors do in this paper is they set up two alternatives and on the one side, say the authors, are those people advocating the hypothesis, people like me, that people learn best in an unguided or minimally guided environment.

(Just as an aside every time I quote from them I’ve very sensitive to their use of language. Their use of language is very often loaded or prejudicial and I’m trying to be careful not to be drawn aside by that. “In an unguided or minimally guided environment.” What does that mean?)

Generally defined as one in which learners, rather than being presented with essential information, must discover (now they throw that word discover in there very deliberately because they want to tie it to discovery learning) or construct (there you go with constructivism right) essential (notice that word ‘essential’ - that word has a whole philosophy that comes with it, the whole Saul Kripke essentialism view of the world that there are certain innate natures of things) information for themselves. So that’s the bad thing.

On the other side, this is their view now, are those suggesting that novice learners should be provided with direct instructional guidance on the concepts and procedures required by a particular discipline (we’ll come back to that) and should not be left to discover, (notice how it’s changed a little bit from the first presentation) those procedures (again a very careful word) by themselves.

Just as an aside before I get into the main criticism, I was uncertain, and of course they do not discuss in the paper, what a novice learner is. There’s a certain sense in this paper that a novice learner is any person who has not learned what needs to be learned. And if you read the paper a certain way the paper says if you already know what is being taught you have no problem being taught it, but if you don’t know, then you have to be instructed, properly so called. That would be an unfair reading of the paper, but they leave it open because they don’t tell us what a novice is. Is a novice a baby? Is a novice a 10 year old? Is a novice a first year student in a college or university? We don’t know.

So what do they mean by minimally guided learning? Everything! The old theories of discovery learning, problem based learning, inquiry learning, experiential learning, and of course, the most recent thing, constructivism and, if they had thought of it and felt so inclined, they would have included connectivism and on line learning probably all in the same breath.

There are two assumptions, they say, to this unguided kind of learning. The first assumption is that students should be challenged to solve authentic problems (notice the scare quotes) or inquire information, acquire knowledge (again notice how that is phrased, ‘acquire knowledge,’ I’m going to get it from here and I’m going to put it in here) in information rich settings. And they say (notice again the loaded term, the assumption right, as though we’re just making it up) the assumption is that having learners construct their own solutions, whatever that means leads to the most effective learning experience. And then the second assumption, they say, is that the non-guided people assume that knowledge can best be acquired through experience based on the procedures (the discipline). We’re going to come back to that.

Now their argument, this is their main argument here, it’s a nice categorical syllogism. I like categorical syllogisms because they’re so easy to work with. Any instructional procedure (i.e., ours) that ignores the structures that constitute human cognitive architecture (now there again, ‘human cognitive architecture’, as though the mind is like a house) is not likely to be effective. There, you can see where this is going, right? Minimally guided instruction appears to proceed with no reference to the characteristics of human cognitive architecture. So we’re just one of those things. And indeed, what they mean now (we’ll come back to this later in the talk) by ‘human cognitive architecture’ is the characteristics of working memory, long-term memory and the relations between them. Okay, fine. We’ll come back to that. Thus, they conclude, minimally guided instruction is unlikely to result in effective learning.

You see why I certainly worry about papers like this is because what they’re saying basically is the approach that people who are talking what 2.0 learning, 2.0 blogs, wikis, social practice, communities practice and all that, has no grounding in the theory of how the mind works. And that’s a very serious charge. Turns out to be false but it’s still a very serious charge.

So this is their credo, their manifesto, a.k.a. their conclusion: after a half century of advocacy of minimally guided learning (people like me) it appears there is no body of research supporting the technique. Now, off in the distance you can hear the howls and the wails of protest from the people who have been studying this stuff for 50 years and have found that it works, but we’ll leave that aside.

Insofar that there is any evidence, they argue, it almost uniformly supports direct strong instructional guidance rather than constructivist based minimal guidance. Not only is non-guided instruction less effective (they even talk about this for a bit) it may produce negative results.

And you ask, “How can that be?”

5. The Reality Check

Well let’s do a reality check first about their conclusion. Their argument, first of all, is simply inconsistent internally. These aren’t major issues, but it’s a bit of a problem.

On the one hand when they’re busy criticizing the minimally guided research they say instructors can’t apply it, they always cheat. They always do some scaffolding. They won’t let students discover things for themselves. They’re always suggesting, telling them what to do and all of that. Okay, fair enough.

But on the other hand, they say that minimally guided instruction is failing. Well either they do it and it doesn’t work, which is bad, or they don’t do it. You can’t say both. You can’t say they’re not doing it, and it doesn’t work.

And then also the section later on in the paper they talk about how minimally guided learning, discovery learning, constructivism, and problem based learning especially, are used in 50 medical schools in the United States. Now I hadn’t heard any particular criticisms about the quality of doctors in the United States. Maybe that’s just a fluke.

But they examine this and they say the strongest criticism they find in those doctors, because the doctors turn out to be fine, but in their paper, they recommend, “unnecessary procedures,” and it strikes me knowing the American medical system, that the last cause of the recommendation of unnecessary medical procedures is the kind of learning that we do. This is the most litigious society in the world. If you drop your pencil you will be sued. That is why they recommend unnecessary medical procedures (whatever those might be) not because they were taught to use problem-based learning.

But be that as it may. Their conclusion is simply not plausible. It doesn’t make sense. It’s not believable. We know that people learn using problem based learning and inquiry based learning. There’s a huge body of research and Hmelo-Silver, Duncan, and Chinn cite numerous studies in their response to the Kirscher, Sweller and Clark paper. And even without that research we know that people learn without guidance because we see it all the time. We have the evidence of our own senses.

Nobody went to school to learn how to build the Internet. Nobody was instructed (‘they said well first you get a website, get it on the web, get some HTML’). People discovered that all by themselves, and it turns out that the mechanisms of computers are things that even small children can learn by themselves.

Many examples, I’ll just point to one. It’s called the ‘hole in the wall gang’ and what they did in cities in India is they would take a computer, they put it literally in a hole in a wall and so the make it assessable to the children in the community. These are children in India, so it’s not like they’re growing up working on their laptops at home. And so they get this computer. They’re not instructed in any way. They learn how to operate it, they learn how to program it and they learn all kind of things about this computer without being told to do anything. So we can see that this works.

Even more to the point, instructivism is a kind of learning by telling; it’s a kind of learning by giving people the information, the concepts, the facts. But we know that people have to learn by practice. Learning is not being told. Learning is doing.

Examples are all over the place. Deanna Kuhn writes that we can hope to impart the smallest fraction of knowledge in any science. How could we possible teach science by teaching facts when there is not literally, not enough time to put all the facts in people’s heads? Even if we were putting them in one after another every second of every day, there’s too many facts in science. We have to do it a different way.

Think about what you would want in medical practice. Would you want a doctor who was told about medicine or a doctor who practiced medicine?

Their argument is based on a straw man. Inquiring learning, problem based learning, are not examples of ‘minimally guided learning’ and again, Hmelo-Silver, Duncan, and Chinn talked about this at some length. They are based on the process of scaffolding, they are based on direct instruction when needed. Indeed, my criticism of problem based learning and inquiry learning is the instructor is too involved. I think there’s too much instructing happening in these kinds of learnings and that there should be less. But that’s a separate argument for a different day.

Their argument is a false dilemma and this is the easy and obvious criticism. They are offering (remember at the very beginning where I presented their argument) the choice between minimally guided instruction or strong instruction. And it begs the question who is doing the choosing, doesn’t it?

This is the example I like to use for this. Imagine my first visit to Rome. I remember getting off the train and walking out and I’m in Rome, in the train station. I have no idea what I’m doing and so a number of things present themselves here, right? I could take a guided tour. I could get a map and walk around myself. I could just walk around aimlessly and never find my hotel or… these are all things where I am choosing what to do, right? And the alternative is, to be kidnapped and to be told where to go.

Now the alternatives are not ‘being kidnapped’ or ‘being lost’. There’s all kinds of ground in between, all kinds of ways that a person can receive guidance that is not in the form of direct instruction. And so their argument is a straw man, yet again.

People who are minimally instructed are in no sense cast adrift. So in preparing this paper for today, nobody told me how to prepare this paper, but that doesn’t mean that I’m sitting all alone. I put out messages in e-mail, I log onto websites, I got all kinds of information back, really helpful useful information that mapped out the territory for me, told me about resources I hadn’t found, pointed to me through objections. I got lots of guidance when I was preparing this talk, but I was not instructed.

And this is a general criticism. This isn’t just me. There’s a social dimension to much learning and Miles Berry points to that in his criticism of the article. A lot of learning, even traditional learning in the classroom, contains a large social dimension as you interact with the other people in your class.

6. Scientific Practice

There are some deeper misunderstandings in this paper as well and I want to explore them. Let’s turn to Kirschner, Swellers, and Clark’s explanation of why learning turned out to be the way it is. And their explanation is inexplicably US-based, but we’ll leave that aside.

They identify the curricular reform that happened after Sputnik (it’s kind of neat, Sputnik happened and then I was born; I came into the world roughly the same time as Sputnik, so I am a product of these reforms, maybe that’s what really scares them). And what the reform is, they say, and it’s repeated throughout the paper, is that it’s based on the assumption that knowledge is best or can only be acquired or learned through experience that is based on the procedures of the discipline. And they repeat this four or five times, I didn’t count them, in the article.

And so they’re saying the assumption here is, if you want to learn physics you should practice physics the way a physicist does, which is what I said at the beginning of this talk. And this has led, they say, to this unguided project work (I did lots of projects when I was in school: Ecuador, the Danube River…) and a rejection of instruction (this is the key phrase, it’s repeated several times in the paper), a rejection of instruction based on the facts, laws, principles, and theories that make up a discipline’s content.

That’s a pretty common view, isn’t it? There’s probably fewer advocating wikis or weblogs or something like that, Wikipedia. People are saying, “what about the facts, what about the laws, what about the content that actually is the discipline, physics, or mathematics or whatever?”

And they say it may be, they say it is, an error to assume that the pedagogical content of the learning experience is identical to the methods and practices of the discipline being studies. So what they’re saying is that the basic fundamental assumption of my own theory is in error. And it’s a mistake to assume that instruction should focus exclusively on application (well it’s one of those weasel words, ‘exclusively on’, it’s not what they mean, what they mean is it’s a mistake to say that instruction should be application).

Well what do they think? How do they think science works? Because if it’s a mistake to adopt that method, then the nature of that method is pretty important, don’t you think?

Well, happily they explain it in a couple of places for us. One place they explain it is when they discuss Kolb (1971), and Kolb and Fry (1975) and they present a process where a person carried out an action and sees the effect, and then they see this and they understand this effect and begin to anticipate the consequence, and as a consequence of that, they generalize. They understand the general principle.

It sounds like discovery learning. And they extend this to other types of unguided or minimally guided instruction. It’s one of two major components of problem-based learning, they say in their paper: explicit teaching of problem solving strategies in the form of the HD (hypothetical-deductive) method. Barrows & Tamblyn 1980. 1980 is kind of significant because (Thomas) Kuhn was only about 1974 or so.

And then teaching, it’s the same principle. Teaching of the basic content in the context of specific case or instance. So again the same sort of set up here. You have the specific and as a student you’re supposed to generalize. That’s the law. And there’s the problem. That sort of way of going about learning, they argue, might not be the most appropriate way to solve problems. In fact, it’s really difficult, especially in clinical settings, especially in “information rich environments.” It’s really difficult to come up with generalization. You’ve got all kind of convenient hypotheses (that reminded me of Chomsky when he talks about the poverty of the of stimulus). There’s so much information it’s really hard to pick the right generalization.

But the thing is, real science - the stuff that real scientists do in real labs - is not the hypothetical deductive method. Hasn’t been since the ‘50’s. It was developed by Carl Hempel, and the ink wasn’t even dry on the page when Hempel and other logical positivists like A.J. Ayer were being criticized all over the place. Karl Popper, right off the bat, not verification but falsification, which is very much not the HD method. And numerous others. Kuhn - Thomas Kuhn. Lakatos. Lauden. Feyerabend. All pointing to the fact that scientists in practice do not practice the HD model. Nobody does it.

What is science? Science according to Thomas Kuhn (The Structure of Scientific Revolutions) is a community process. The process is not argumentation and it’s specifically not inductive argumentation. It’s explanations. The criteria for explanations are theory based or theory-bound and include things like simplicity, parsimony, testability. And explanations aren’t stand-alone facts. They depend on your expectations; they depend on your theories. As Bas van Fraassen says in The Scientific Image, the explanation of something depends not only what caused something to happen, but also in your expectation of what could have happened instead. Obviously.

7. The Prestige

Let’s turn now to the core of the Kirschner, Sweller and Clark paper, which is the ‘cognitive load argument’. This is where you’re going to give you cognitive psychology and tell you, here’s how learning works.

So their theory is based on the theory of long term and short term memory. They’re not going to be interested in sensory memory (I find that a very interesting statement I’m not going to linger on) and the manner in which our cognitive structures are organized. You’ve heard this before, right? You have short term memory, you have long term memory. Short term memory is the stuff that we are consciously aware of. Long term memory is the stuff we aren’t.

Long term memory is - and these are their words - a ‘massive knowledge base’ and anyone who understands cognitive structures knows how bad a statement that is. If you looked at the structure of the mind, it does not resemble a knowledge base at all. And I won’t get into the details of it, but neural structures and databases are two very different things.

And they say, you’re skillful in an area because your long term memory contains huge amounts of information, so it’s a theory knowledge based on quantity, piled fact on fact on fact. And then they cite – astonishingly – DeGroot’s work on chess expertise. But, you know, I play chess. And there’s this fiction that chess players who are really good chess players can predict ahead, and they can keep all these different board positions in their head. But you cannot defeat a computer like that. The computer will always predict ahead further than you. But people still can beat computers because they visualize, they recognize, successful formations. They don’t memorize a whole bunch of chess positions; they see what is going to work and what is not going to work.

This is Kirschner, Sweller and Clark again: they say the alternate means of instruction is justified by this cognitive theory of long term memory. And the aim of all instruction they say is to alter (nice word there, ‘alter’) long term memory. If nothing has been changed in long term memory they said nothing has been learned. It harkens back to the logical positivist principle of verificationism, that a difference that makes no difference is a difference at all. Or in Bergmann’s formulation, in the dark, all cows are black.

And then the other side of the theory is that working memory, short term memory (and we’ve seen the research on this) has limited capacity, has limited duration, only lasts for a few minutes and is restricted to a small number of elements - the famous number seven elements. We’ve done lots of work on that. Seven elements doesn’t mean seven digits because if you taught to cluster things you can actually remember more than seven. That’s going to form an important part of their theory.

Here’s where the prestige comes in (that’s from magic, right, the movie, you do your trick and then you do the unexpected thing and it all comes together and all the crowd goes ooh ahh). Here’s where it all comes together.

Most learners can, to use their words, construct knowledge. People can actually spot the generalizations. And to do this you must construct a representation. Now this representation, they say, is equally good whether you’re using full information or partial information. So if you have the full information you’re really not losing anything, but if you have partial information, part of your short term memory is occupied in trying to search for possible theories or hypothesis. And because you’re searching for what theory this data could fit into, you’re overloaded, your short term memory is overloaded and you are not able to focus and actually think about what you’re supposed to be learning.

And so, constructivist – because it’s making you search for these theories - is not a good prescriptive instructional designed theory. It’s too hard.

8. Personal Knowledge

Well it’s all in the search, isn’t it? And this is the putative ‘worked example effect’, where you’re doing a search for the hypothesis (imagine a logic problem, “oh what principle am I going to apply, am I going to apply transposition, composition or whatever?”). So you’re searching these hypotheses, and it’s unrelated to learning, you’re trying to find the best fit, but if you’re studying a worked example, the theory has already been picked for you and you’re looking at what has been done. You’re learning by being told.

The problem is, problem solving - real human problem solving - doesn’t work that way.

We don’t do this mental search of our internal hard drive and try to find the right theory. That’s not how it works at all. We don’t have a whole bunch of general principles or theories stored in our head. Rather we looked at the data and we recognize patterns in that data. It’s a process of seeing rather than searching. This is why is so interesting that at the beginning of this they dropped perceptual memory as though it was completely irrelevant. But perceptual memory is totally relevant because perceptual memory is a process of recognition.

There’s even in the literature there’s discussion of this (I’m not just not making this up). Stephen Kosslyn, for example, image-rotating examples, the theory where you’re going through algorithms and processes does not explain reaction time when you’re asking people to visualize the rotation of images. We work on a sub-symbolic level, not a symbolic level. Cognition is based on a process of pattern recognition at that sub-symbolic level.

And we know this. There has been a lot of discussion about experts and schemas and how an expert will acquire a frame – to use Lakoff’s term – or knowledge of organization. And they even admit, the authors even admit, cognitive research has shown that to acquire expertise in a domain the learners must acquire the necessary schemata.

But what are schemata? What is this ‘picture of domain’ that a person must have. They (Kirschner, Sweller, Clark) think it is facts, laws, principles, and theories that make up the discipline’s content. But this is simply wrong. It is an incorrect understanding of science. And they ought to know that.

Bloom’s Taxonomy talks about types of learning that are not facts, data, and all theories. Or Michael Polanyi, his book Personal Knowledge, talking about personal knowledge, the difference between ‘knowing that’ and ‘knowing how’. And what’s important about Polanyi’s work is that he says, the bulk of our knowledge, even our conceptual knowledge, is ineffable. That means it cannot be represented in words, which means that a statement (which is a theory) is not a good expression of that knowledge, and that a law is not a good expression of that knowledge. The configuration of connections in your brain, that is a good representation of that knowledge.

Knowing a discipline is knowing the practice of that discipline. It’s learning to think like a scientist or a forester or a hockey player, and learning to recognize, to see the way they see, to speak they way they speak their words, to judge the way they judge.

And that’s what we are producing in the read-write web. The read-write web, the web in which we talked about what we’re doing, we reflected, we practiced, is developing these new kinds of literacies, these new ways of people being able to express how people think - that is, how they talked, how they practiced, how they judged, how they evaluated. There’s a nice picture of this, the revision of Bloom’s verbs that includes verbs tied to the social infrastructure skills and abilities that help people learn and help people grow new mental configurations, grow in knowledge in this environment.

The pedagogy in this environment is based on personal learning. It’s based on the acquisition, the developing, the growth of capacities and aptitudes - like recognition - rather than laws and facts and theories and data. I tried to talk about this a little bit in a paper I presented the last time I was here in Holland called Things You Really Need to Learn. And I talked about the general principle, how to predict consequences. How to stay healthy. How to live a meaningful life. These are the core principles, the core things that people need to learn, not facts and data.

I’ve talked about the semantic principle, the mechanisms, the ways we design our networks in order to make the most reliable system for recognizing patterns in the environment and these principles I put under the headings of Autonomy, Diversity, Openness, and Interactivity. And I’ve talked about the principle of personal learning, the idea here that you develop your own learning yourself. You make your own learning and the way you make your own learning is you find the relevance in the environment. And that has to do with similarity or salience and Amos Tversky, interaction, communicating with your community, and then usability, just being able to speak the language, use the interactions.

That’s the theory that is really supported by, if you will, the cognitive architecture. And so that’s my refutation of Kirshner, Sweller and Clark and my presentation of the alternative connectivist theory of knowledge. And I thank you very much for your time.

Not the Edublog Award Winners

This is a list of sites that should be recognized but which, for one reason or another, were overlooked by the Edublog Awards. Sites that probably should have been nominated, and could even have won, but weren't, and obviously, didn't.

Let me note that this is not a criticism of the Awards or the nomination process. It could have been perfect, and I would still have been able to find worthy sites. This post is intended only to shine some light on some people who really deserve some praise and wider notice. Think of it as my personal 'honourable mention' category.

Best educational use of a virtual world: Media Grid Immersive Education

Immersive Education is an award-winning learning platform that combines interactive 3D graphics, commercial game and simulation technology, virtual reality, voice chat (Voice over IP/VoIP), Web cameras (webcams) and rich digital media with collaborative online course environments and classrooms."

What I like about this initiative is that it is not bound to a single platform, that it is actively contributing to specifications and technologies that help virtual worlds together, and that it is actively exploring ways in which immersive technologies can be used to support learning.

Best educational use of a social networking service: OU Course Profiles on Facebook

What makes this different from the typical use of a social networking service is that it is substantiall about using a social network service to support learning, rather than simply using it to connect the same old group of people together. What I mean by this is that it is intended for students and that it inserts a useful educational service into the social network application (in this case Facebook). Here's a slide show and more description of the app.

Best educational wiki: WikiEducator

Numerous educational wikis could have taken the podium here - Curriki, Wikiversity, more. WikiEducator is chosen as the most (apparently) active of these initiatives. "WikiEducator is a dynamic and exciting community of educators who believe passionately that learning materials should be free and open to all." Be sure to check out WikiEducator's definition of libre knowledge.

Best educational use of video / visual: Civilization III and World History

This is a 10 minute video describing how Civilization III, a computer game, is used in history classes at Kimball Union Academy, featuring Lyn Lord. This video, one of the highest rated and most viewed on the popular TeacherTube educational video hosting site, mixes screen captures and commentaries showing how the popular video game can support learning.

Best educational use of audio: iTunes University

This was probably the most publicized of the educational podcast initiatives of 2007 and certainly the most influential. The service launched in 2005 with a series of podcasts from Stanford and spread to a number of other universities. The Best of iTunes University site shows just how pervasive this initiative has become.

Some people (including myself) have criticized the initiative for being commercial and proprietary. Which it is. But it is worth noting that there is (to my knowledge ) no comparable free (libre?) and open audio content available from any other collection of universities. Although educational podcasting will already remain a niche market (it's hard to compete with Radiohead) but remains nonetheless important for thousands of people.

Best elearning / corporate education blog: Off Course-On Target

Wayne Hodgins has been around forever, but blogging is a new medium for him, as most of his work has been done in standards committees and academic papers dev eloping and advocating the concept of learning objects. Whatever your views of this persepective on online learning, his blog posts are consistently the most original and informative coming fromthe corporate perspective (and make no mistake - the corporate perspective these days is overwhelmingly the world of SCORM, learning objects, and metadata standards).

Best educational tech support blog: Computer Science Teacher

Alfred Thompson is rooted in the world of Microsoft products, a fact that irks me every time I read one of his posts. But I do read one of his posts because of the steady and consistent stream of practical advice being handed out on his blog. Though aimed ostensibly at computer science teachers, the blog is a constant source of technial advice for any teacher using computers (um, and Windows).

Thompson is (for me) the representative read from an entirely different blogging community from the one we're used to reading. He works for Microsoft and has a direct connection not only to computer science teachers but also the Microsoft developers' network. This gives him a unique perspective and an informed view.

Best library / librarian blog: ACRLog

This has been one of the most consistent high-quality blogs of any type, and I must admit to having been astonished to see it skipped over in the nominations for the Edublogs. It is probably because the blog owners resist efforts to rank it and reward it - probably the best attitude to take. Certainl a lot more dignified than shameless campaigning.

Writes one of the authors (theirs is a group blog): "I suggest that if we want to acknowlege our community’s bloggers who are doing really good work (high quality writing, regular postings, originality of ideas and topics, innovative suggestions, etc.) let’s all contribute to an annual listing - not numeric rankings - but a collection of ten blogs worthy of our praise." I concur, and that's what I'm doing in this post.

Best teacher blog: The Open Classroom

Though this category saw by far the most nominations, it still managed to overlook consistently strong entries from Clarence Fisher, Chris Sessums and Heather Ross. I was tempted to opt for a Canadian in this category, but opted to highlight Australian nglish teacher Jo McLeay, who has been writing consistently and quietly for several years now. She also practices what she preaches, linking to a number of her classroom blogs. She uses many of the Web 2.0 tools and is plugged in to the Australian edublogging community.

Most influential blog post: Death threats against bloggers are NOT 'protected speech'

Though Kathy Sierra was widely read in the blogging community at large, she was arguably an edublogger - certainly, her work was widely cited in our community and I suspect that had she not stopped blogging shortly after posting this bombshell she would have certainly shown up in the Edublog Awards in severl categories. Sierra combined an intuitive sense of design with a deep knowledge of online communication to create posts that were memorable and wity.

And yet, because of the events described in this post, I refer to her work in the past tense. She abruptly withdraw from the blogging scene after a series of harassing and blatantly sexist attacks. Her experience was hardly unique; since then I have read numerous other accounts of gender-based online abuse, and of course you can find it if you look in almos any YouTube or Digg comment stream. What these tell us about the current state of our society is disturbing. But at least - to judge both from the hit and link counts in Edu_RSS and the 1165 comments on her website, Kathy Sierra's message has certainly hit home.

Best resource sharing blog: Jane's E-Learning Pick of the Day

It was nice to be nominated in this category myself, for OLDaily, but to be honest, I expected to compete against - and lose to - Jane Hart's incredibly useful contribution to the field. Hart has a wealth of experience in the field, having most recently co-founded the consulting firm Waller Hart Learning Architects. In the meantime, her daily resource offers sites, services and tools that are invariably of interest and frequently of direct practica impact.

Best new blog: Helge Scherlund's eLearning news blog

It's hard not to want to give the nod to Sue Waters, but she was nominated, and anyways, Helge Scherlund burst onto the scene with a fresh and informative weblog summarizing resources, websites, and journal articles. She would also have been a wonderful candidate in the best resource-sharing blog category. Scherlund is summarizing - and making accessible - resources that mostly do not grace other edubloggers' pages, making her work well worth reading, especially by those now limiting their reading to a smaller circle of writers treading more familiar territory. She brings an academic edge into what is often a non-academic field, and for that should be recognized.

Best group blog: The Pulse

Hosted by District Administration magazine, the Pulse is one of those blogs that you at one wish would publish more and more and wish would cease and desist. With opinions ranging from insightful to infuriating, with a literate and experienced writing staff, the Pulse distinguishes itself with quality writing, informed opinions, and more controversy than you can shake a stick at. It is a site definitely deserving of wider attention.

I also want to add as an honorable mention in this category the ongoing dialogue between and Deb in Bridging Differences. The debate covers most of the controversial issues in education over the last 15 years, framed by two people who were at the centre of those debates. It is continually interesting to see their views at once shift and at the same time hold fast to basic convictions. Again, what makes this blog work for me is the literate and informed quality of the writing.

Best individual blog: Cool Cat Teacher Blog

This was probably the best nominated of the categories. I would have added Doug Noon, Artichoke, Christopher Sessums, Seb Schmoller and Scott Wilson. But the writer who most deserved a nomination - and didn't get one - was in my opinion Vicki Davis. A teacher from Georgia who writes with a consistently hopeful and uplifting tone, Davis is unquestionably one of the major thought leaders in the American K-12 blogosphere and certainly one of their most articulate representatives. I don't always agree with davis - and to be honest, sometimes roll my eyes - but her popularity both in my Edu_RSS statistics and the wider web at large do not lie.


Regarding my Edu_RSS statistics: I don't have anything to release because these stats are very partial and in some ways very misleading. Edu_RSS ran for only about 6 months of 2007 (and isn't running at the moment while I tune up its efficiency). I do hope to have better statistics available for next year.

Really Simple People

Posted to the social-network-portability mailing list, December 14, 2007.

Ben Werdmuller wrote:
I would argue, strongly, that user data needs a more flexible,
permissive format: an RSS for people, rather than something rigid and

data should ever be rejected because it doesn't fit into the model.

Seconded. This domain is becoming needlessly complicated.

I have argued in the past for a 'Really Simple People' format. RSP.

Here's one:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">
<name>Stephen Downes</name>

This file should be located in some obvious places. If you have an OpenID, for example,

put it here:

or put the address in the head your home page ( here, right beside your RSS:

<link rel="alternate" type="application/rsp+xml" href="" />

and in your RSS file, put it in the head (as the author of the feed) or the item (as the author of the item):

<author rsp="" />

or put the OpenID in the same place, since it leads to RSP

<author OpenID="" />

this is dead simple and introduces agency to the (semantic) web. Numerous graphs can be generated by tracing connections between resources and authors and back again. Friend list can be *derived* from such agency, rather than explicitly created.

But if you want to create friends:

<?xml version="1.0" encoding="UTF-8"?>
<rss version="2.0">

<friend rsp="" />


<friend OpenID="" />

If you wish, you can add a typology to friends. Some examples:

<friend OpenID="" relation="family" />

<friend OpenID="" type="best friend"/>

<friend OpenID="" topic="knitting"/>

That's it. That's the whole of the specification.

Oh, sure, you could add some obvious fields to RSP, like:

<home phone>

and the like. There's no reason to be really precise about this list, especially at first. See what falls out in actual usage.

And additionally, it would be possible to extend the specification using namespaces, just likie RSS. So you could add API for messages and comments, iTunes playlists, more...

<?xml version="1.0" encoding="UTF-8"?>
<rsp version="1.0"

I understand why things in the OpenID space and the social network portability space have become so complicated so quickly. We want to be ale to do a lot, and do do it reliably and securely.

But open and simple should be the default. Don't make the tightly secured athenbtication required etc etc version the default. Even simple things - like, say, email sha1sum, are a real pain for people who don't care to encrypt their email. Allow the use of an email sha1sum field, certainly, but don't make it the default in the format.

Anyhow, end of rant. If you did this, you'd get your portable social graph. Or conversely, to the extent that you're not doing this, you are pushing a portable social graph further and further from reality, pushing it into the hands of specialized agencies such as Facebook and Google.

Tax Cuts

Letter to the Editor, Times & Transcript (Moncton)
Re: Give citizens their money back (editorial, December 13, 2007, p. D6)

It's nice that we have a budget surplus of $79 million. But we should not be calling for tax breaks as a result.

There is a lot we could do with $79 million. It could go toward schools, hospital expansion, a convention centre, a stadium, or restoration of the Petitcodiac river. Or we could use the money to help pay down the provincial debt, which will cut down on the interest payments we must make every year.

Calling for tax breaks is like recommending that we take the money and go out drinking instead of buying food or paying the Visa bill. It's irresponsible, and those advocating tax breaks should know better.

Besides, we all know that we will not each get $105. Large corporations will get most of any tax break. Doctors and lawyers will get larger tax cuts. They won't spend the money in New Br
unswick, they'll invest it in their retirement savings or spend it while on vacation in the Bahamas. The average New Brunswicker will get 29 cents and a handshake. And none of us will benefit from the budget surplus.

If the editorial writers really wanted to give the money back to the people who need it, they could give the 7900 poorest people in the province $10,000 each. They would buy food or pay their debts. They would spend the money right here in New Brunswick. And it could help lift them out of poverty.

Tax cuts benefit only the rich. That's why it's always the rich people who are calling for them. Tax cuts take services and support away from the people who need them. You can't educate a child, get emergency surgery, or drive to work on a $105 rebate. But $79 million buys all of these things for us, and more.

People who are advocating tax cuts are thinking only of themselves, and are not thinking of the greater good for most people in this province.

These Principles

Responding to Vicki Davis, Non Partisan Basics of Democracy.

I am in general agreement with the sentiments expressed in Friday's post and in this post.

As noted before, I don't equate these thoughts with 'citizenship' per se. We do not, for example, have 'civics' classes in Canada. These ideas are not bound by, or limited by, any idea of statehood or nation.

It is important to understand that the institutions we create - laws, governments, courts, borders - are structures intended to serve certain ends, and are not the ends in themselves.

The founders of the United States realized this, which is why their constitution and declaration of independence are prefaced with those objectives.

It was, among other things, the value of life, liberty and the pursuit of happiness, that justified the structures they built. The structure served these values; there values were not merely 'allowed', but were foundational.

That said, I have written a great deal about this topic in the past, and have offered not only criticism but rather a wider discussion of life and society in general.

I have, if you will, in my previous work, defined a set of what might be called 'social virtues', as well as a set of what may be called 'personal virtues'.

It is foundational to my thought that these ought to be, and must be, separate; that the values of the state (or society at large) are not, need not, and cannot be, the values of the individual.

An individual may have faith, for example, but the state can not. An individual may reason, but the state can not. A collection or group of people does not have the properties of an individual person, and the presumption that the one is like the other is based on a fallacy.

I have described the social virtues in my work on groups and networks. These are the values a society needs to embody in order to function (as the U.S. founders said) as a 'more perfect union':

Autonomy - each person must be free to pursue his or her own good in his or her own way.

Diversity - the widest possible range of beliefs and opinions ought to be sought and encouraged.

Openness - each person ought to have the ability to contribute in his or her own way, and to be able to receive the contributions of the others.

Interactivity - ideas and expressions are communicated from one to the next, originating from many different sources, rather than from one to all, diffusing from a single source.


I have also described at length the personal virtues. It is these I think that Richard Dreyfus was discussing: "civility, reason, logic, clarity, dissent, and debate." See my paper, 'Things You Really Need to learn':

1. You will find in this elements of reason - how to predict consequences, for example, or how to distinguish truth from fiction.

2. You will also see elements of civility and communication - how to read, how to empathize, and how to communicate clearly.

3. And you will see elements of what may be called personal faith or personal autonomy, the things that give one self-value and meaning: how to be creative, how to stay healthy, how to value yourself, how to live meaningfully.

Now let me address the other aspect of Dreyfus's comments, specifically, that these values must be taught, or they will be lost.

I certainly agree with this, but I want to be most careful about what we mean when we say, they must be taught.

Merely standing in front of a class and uttering the words does not constitute 'teaching'.

I have argued in many places that 'to teach' is 'to model and to demonstrate'. We cannot merely mouth the values we wish to pass on. We must live them - that is, we must demonstrate in our personal conduct the virtues of reason, communication, and self-worthy; and we must align ourselves socially with the virtues of autonomy, diversity, openness, and interactivity.

To the extent that we fail to model and demonstrate these virtues in ourselves is the extent that we fail as teachers. And, so we should make no mistake, we are all teachers, not just those of us who stand in the classroom.

And as teachers, we must model and demonstrate the principle attributes of learning, so that our students can best see how to emulate and follow our example. To 'learn' is to 'practice and reflect', and we should, therefore, make a sincere effort to practice what we have been shown, and to reflect openly on that practice.

I do not embody this entire statement in everything I write, because although brief, a constant repetition of these basic principles would become tiresome.

But these principles, it should be understood, underlie everything I say, everything I do.
