There was yet another Andrew Keen inspired article last week bemoaning the age of “wikiality” — an age of supposed gullibility of us internet sorts. It begins with shocking news — people are getting quotes wrong, and Web 2.0 is at fault:

Truth: Can You Handle It?
Better Yet: Do You Know It When You See It?
By Monica Hesse
Washington Post Staff Writer

How many legs does a dog have, if you call the tail a leg? Four.
Calling a tail a leg doesn’t make it a leg.

Abraham Lincoln *

[*Note: Lincoln never said this. He liked a similar, more long-winded anecdote about a cow, but the dog version? Nope. Still, the quote is credited to Abe on some 11,000 different Web pages, including quote resources Brainy Quote and World of Quotes.

Though not technically “true,” the quote makes a nice start to this article about truth, being topical and brief, so if we want to go with truth-by-consensus (very popular now), we can go ahead and just say that he said it.]

Hesse then explains the crisis:

Andrew Keen describes it as “the cult of the amateur” in his same-named book. Stephen Colbert called it “wikiality” — meaning, “a reality where, if enough people agree with a notion, it must be true.

Information specialists call it the death of information literacy.

What’s really amusing about the Hesse article is that her initial example – the Lincoln quote – is an example where the web was more correct — and the web could have shown her that. The web has well known conventions for dealing with authority and making truth more verifiable, and when these conventions are embraced rather than rejected, one gets better results.

Follow along while we compare what it takes to verify truth on the web, and what it takes the “old world”…

Score one for wiki-world

Hesse seems to be claiming that the web (and it’s tendency to magnify casual opinion over scholarship) was responsible for this quote being wrong. But was the quote actually wrong? That seemed an important point — and nothing in the article seemed to prove the “Brainy Quote” version false — nothing, that is, beyond her simple assertion.

I decided to use the web to find older, more authoritative references to the “false” quote. It was easy once I realized that I should include the phrase “said Lincoln” to filter out simple non-contextualized quotes, such as one finds in quote lists. In fact, once I figured that out, an extremely early instance was on the first page of results [Note: my posting this article appears to have altered that result set].  It appears in a work called Lincoln’s Own Stories published in 1912:

Once when a deputation visited him and urged emancipation before he was ready, he argued that he could not enforce it, and, to illustrate, asked them: How many legs will a sheep have if you call the tail a leg?” They answered, “Five.” “You are mistaken,” said Lincoln, “for calling a tail a leg don’t make it so”; and that exhibited the fallacy of their position more than twenty syllogisms.

It took less than fifteen minutes to prove the Hesse article wrong: far from being an false product of the wild web, the quote has an extremely good provenance. There’s a small matter of it being a sheep mentioned, but it matches the “wiki” quotes far better than the “long-winded anecdote” about a cow that Hesse favors.

Incidentally, the web can even show you how the “sheep” may have become a “dog”: Christopher Morely uses the modified Lincoln quote in Parnassus on Wheels in 1917 citing a dog, Wikipedia shows us he was an editor of several editions of Bartlett’s Quotations, which probably explains why the quote appears in his editions of Bartlett’s in the dog variation (no full text online, but see cites here).

That doesn’t seem to me a problem of authority. And it certainly has nothing to do with Web 2.0.

Score zero for the world of “authority”

Then, I decided to try it the other way round — could I prove the Hesse version of the Lincoln quote was from an even more trustworthy source?

Here’s where it gets ridiculous — the article that is bemoaning that people simply believe what they read provides no source for their version of the quote. So whereas you, the reader of this blog, can click the link “Lincoln’s Own Stories” to verify my assertion, to verify something in traditional media requires launching a federal investigation.

To try to find the source for her quote, I took the fact that it involved a cow, and probably contained the core phrase “calling a tail a leg”. Google Web search turned up nothing of use. Google Scholar turned nothing up, neither did Google Book Search. Figuring the author probably read this in a book (or saw it in a documentary) I tried Amazon’s full text search. Bingo.

The keywords I had chosen occurred in the biography “Lincoln” by David Herbert Donald. But the book was not providing a useful context snippet to Amazon. So I went down to the library, and got the book out. I looked up “emancipation” in the index — far too many pages listed. Looked up cow, and of course found nothing. Ugh.

My lunch break was slipping away. In a moment of insight, I went to the terminal in the library and pulled up Amazon.com. I did “search inside the book” again. While the snippet didn’t appear, it gave me the page number: page 396. I turned to the page — Aha! There was the source of the Hesse version. It talked of a long-winded anecdote about a Western case involving a cow.

Which raises the question: why do the defenders of “truth” want to make it so hard to verify their sources?

(The answer, in case you haven’t guessed yet, is they aren’t defenders of truth. They are defenders of authority. And from Ancient Egypt on, authority was maintained by having exclusive access to information… )

I won’t belabor this much longer. The source of the quote in the Lincoln biography is an obscure quarterly from 1950, the nearest available copy of which is in Worcester, about an hour and a half away. I thought of getting the article through Interlibrary Loan, but realized from the title “A Conference with Abraham Lincoln: From the Diary of Nathan Brown” that even if I got the journal, the article relied on a diary that would not be accessible to me.

So the Hesse version appears based on a single, non-primary source which references a journal article the author didn’t read, and the journal article references a diary that neither the author of the WaPo article or the author of the biography has ever seen.

It’s a big circle of trust, none of it linkable. And yet the web people, who are insisting on verifiable, linked sources are somehow the intellectually sloppy ones.

A final check

Still, given my source was from 1912, and the unverifiable source was likely contemporary, I could only prove that the quote being bemoaned as a prodct of “wikiality” had a good history, and was more verifiable. I couldn’t prove that it was more likely. So I called in a favor. I used to be a programmer for the amazing Readex “Early American Newspapers” project, the project to create a searchable full text database of this nation’s periodicals from pre-revolutionary times until 1876. So I emailed a person I know that still programs there. I asked them if they could punch in “Lincoln” and “calling a tail a leg” into the product and send me back the first results.

Sixty seconds later I had my answer — Web: 1, Books: 0.

What Lincoln said to the party visiting him — well, it was reported in the Chicago Tribune at the time.

And it’s not a “long-winded anecdote about a cow”, but rather, it’s much closer to that quote that appears in all those crazy wikis.

Headline: Lincoln’s Own Construction of His Proclamation;
Article Type:News/Opinion
Paper: Macon Telegraph, published as Macon Daily Telegraph;
Date: 10-23-1862; Issue: 841; Page: [3];

LINCOLN’S OWN CONSTRUCTION OF HIS PROCLAMATION — A little while anterior to Lincoln’s interview with the clerical committee (says the Chicago Tribune) a couple of other abolition fanatics found their way to the President and pressed upon him the emancipation scheme, and this was his reply: You remember the slave who asked his master — if I should call a sheep’s tail a leg, how many legs would it have? ’Five’ ’No, only four, for my calling a tail a leg would not make it so.”

(Incidentally, the Readex Collection of Early American Newspapers is the most exciting thing going on in historical databases today — if your institution doesn’t have a license to it, you’re not serious about American History. Go check it out…)

I realize this is a Macon paper (hardly an uninterested party) quoting the Chicago Tribune (as was the custom in early papers). But there are plenty of other hits from other papers in the list as well — I’m staying on the clear side of fair use here, but they are there to be discovered by any user of Readex.

Suffice it to say, however, that the quote, and Hesse’s problem with it, are far more telling than she anticipated.

The subtitle of her article asks if you’ll know truth “when you see it”.

It’s a good question, but Hesse has the battery wired backwards.

The answer, from any web literate scholar, is if you make it easy for me to check it, maybe I will know it when I see it. The web does that in spades, which allows us, ironically, to repair the errors that the Washington Post generates.

SPACEWAR Is Still My Metaphor

It’s important sometimes to realize that while we are blazing new trails in mainstream education, we are really dealing with the dam of industrial culture finally breaking.

We’ve been paying attention enough to know why it’s breaking. We deserve credit for that.

In fact, we’ve been waiting for it to break.

But the ideas that fuel me (and I think possibly you) aren’t as new as most of my colleagues think. What we are looking at is the transference of a hacking culture to a mainstream population. That’s the revolution in a nutshell.

Educational institutions need to turn out more hackers. Because it’s the hackers, not the planners, that will save this planet.

So while the idea of the “hacker next door” might be novel to our co-workers, the culture is warmly familiar to us. It’s decentralized, it values recursion, iteration, intervention. It sees consumer/producer divisions as quaint. It sees five-year-plans as authoritarian and unproductive. It sees the Machine as an extension of Self.

In a way, it was all so predictable.

But I went back and reread Stewart Brand today and, well, if you haven’t read his early stuff recently, treat yourself to it. It will take your breath away. The wisdom of crowds, planner vs. hackers, machines as community builders, it’s all there.

From Stewart Brand’s brilliant 1972 article in Rolling Stone on the playing and creation of SPACEWAR:

Where a few brilliantly stupid computers can wreak havoc, a host of modest computers (and some brilliant ones) serving innumerable individual purposes can be healthful, can repair havoc, feed life. (Likewise, 20 crummy speakers at once will give better sound fidelity than one excellent speaker - try it.)

Spacewar serves Earthpeace. So does any funky playing with computers or any computer-pursuit of your own peculiar goals, and especially any use of computers to offset other computers. It won’t be so hard. The price of hardware is coming down fast, and with the new CMOS chips (Complimentary Metal Oxide Semiconductor integrated circuits) the energy-drain of major computing drops to Flashlight-battery level.

Part of the grotesqueness of American life in these latter days is a subservience to Plan that amounts to panic. What we don’t intend shouldn’t happen. What happens anyway is either blamed on our enemies or baldly ignored. In our arrogance we close our ears to voices not our rational own, we routinely reject the princely gifts of spontaneous generation.

Spacewar as a parable is almost too pat. It was the illegitimate child of the marrying of computers and graphic displays. It was part of no one’s grand scheme. It served no grand theory. It was the enthusiasm of irresponsible youngsters. It was disreputably competitive (”You killed me, Tovar!”). It was an administrative headache. It was merely delightful.

Yet Spacewar, if anyone cared to notice, was a flawless crystal ball of things to come in computer science and computer use:

  1. It was intensely interactive in real time with the computer.
  2. It encouraged new programming by the user.
  3. It bonded human and machine through a responsive broadband interface of live graphics display.
  4. It served primarily as a communication device between humans.
  5. It was a game.
  6. It functioned best on, stand-alone equipment (and diarupted multiple-user equipment).
  7. It served human interest, not machine. (Spacewar is trivial to a computer.)
  8. It was delightful.

In those days of batch processing and passive consumerism (data was something you sent to the manufacturer, like color film), Spaccwar was heresy, uninvited and unwelcome. The hackers made Spacewar, not the planners. When computers become available to everybody, the hackers take over. We are all Computer Bums, all more empowered as individuals and as co-operators. That might enhance things … like the richness and rigor of spontaneous creation and of human interaction … of sentient interaction.

Treat yourself, and go read the whole article now. It should be required reading for anybody going into learning technology.

From email from my co-worker, Jenny Darrow:

I’ve done some thinking about the physical space that we will need to promote and support technology and engagement pedagogies. I’m concerned that our emphasis has been so focused on learning, teaching, and curriculum that we’ve been delinquent in addressing physical space requirements….

She goes onto link to Stanford’s Wallenberg Hall classrooms as examples of new design thinking, which I think is exactly right.

What does Wallenberg replace the traditional classroom with? Reconfigurable space combined with media infrastructure. Few assumptions about what your class will be, but many features that can help it be what you want. Here’s how they put it (emphasis mine):

We have already addressed some of these issues with a new type of classroom design that allows learners and instructors to control the configuration of their environment. Next we propose to integrate this type of room with other learning spaces to form “flexible agenda spaces” designed to adapt, moment-to-moment to the activity requirements of the user community.

To put it even more precisely, the design avoids planning in favor of an environment that encourages hacking.

It’s strange how all these things come together. For programmers, it’s small pieces loosely coupled. For architects it’s reconfigurable space. For graphics people, it’s the move from “design” to “style”.

The upshot everywhere seems to be that design is always perfect for last year’s ideas. But last year’s ideas are not what keeps us moving forward.

If you want to keep moving forward, you’re going to have to hack your space. Metaphorical or not.

Curatorial Teaching

Finally got around to listening to this. It’s good. It’s nascent, but maybe that’s why I love it so much:

http://learnonline.wordpress.com/2007/09/20/10-minute-lecture-george-siemens-curatorial-teaching/

It’s not a total solution to the sage-on-the-stage v. guide-on-the-side but it’s a great rethinking, and it’s very practical to implement.

It’s also refreshing that Siemens approach is not kick-against-the-pricks* (an approach I’m often guilty of) — his approach respects that there is not here a complete historical break with previous teaching, but an accenting of things that were always a part of good instruction, and now need to be accentuated because of the realities of a highly networked world.

*Note on the phrase “kick against the pricks”: Since it seems this phrase is less known than I thought….”Kick against the pricks” is a Biblical phrase meaning roughly “rebel against authority despite immense pain”. It comes from a metaphor involving oxen and sharp pointy sticks. Kicking against the pricks represents an ideological yet futile rebellion against authority for the sake of doing the right thing, rather than out of hope of possible success.

It comes to me not through the Bible, but through the awesomeness of Nick Cave.

Via SmartMobs, regarding our millenials:

“Young people don’t see “tech” as a separate entity - it’s an organic part of their lives,” said Andrew Davidson, vice president of MTV’s VBS International Insight unit.

“Talking to them about the role of technology in their lifestyle would be like talking to kids in the 1980s about the role the park swing or the telephone played in their social lives — it’s invisible.”

The more you get into “tech”, the more you realize there’s no such thing. As any systems analyst will tell you: there are processes, and some pieces of them are automated and some aren’t. Some pieces have hardware components, and some don’t. Some storage is on paper, and some on tiny electric switches.

The process is inviting your friends out for a drink. It’s not using the telephone in drink invite mode. You don’t start out and say I need a product to invite my friends out for beers and optionally gin and tonics. And we don’t really worry that the phone is from one vendor, and the cab you take down to the bar is from another.

What we say is — hey, wouldn’t it be neat if instead of having to call everybody seperately I could communicate with them all at once? And slowly that process evolves…

What’s my point? I suppose it’s that from a process standpoint, if we see our personal algorithms as the higher order application, loose coupling has been the norm, more than we realize.  And given the worldview of the current crop of kids, we’re likely to get back to that. And that’s a good and powerful thing.

Loosely coupled assessment

Here’s the thing – it’s 2000 all over. Eportfolio is the new LMS.

Watching a recent vendor presentation I thought – I can’t believe this is happening again. That single phrase. In a loop. In my head.

Because remember — this happened once before. The LMS vendors came in with an assessment and management tool, and told us it was an elearning solution. At the time, I was on the other side of the equation, with a company trying to sell award-winning goal-based scenario software to colleges who were saying — but we already HAVE an elearning solution. It’s called Blackboard. Or WebCT. Or whatever.

And so Blackboard, an assessment and management tool, determined the pedagogy of colleges for eight or so years. Because teachers wanted to import rosters, we put students in a closed box and told them it was elearning.

When it wasn’t. The truth is the kids were doing more elearning on MySpace than in Blackboard.

How do we avoid it again? How do we avoid imposing something that is just pedagogically WRONG on a new set of students because we need to meet some institutional assessment needs?

There’s only one way — loosely coupled assessment.

If we are going to talk assessment, we are going to have to segregate it. Your assessment tool should ONLY assess.

We don’t need to talk more about student needs wth vendors that supply assessment tools. We need to talk to them less about student needs. It’s not their business.

Literally: it is not their business.

In fact, we should remove student needs entirely from the equation.

The students know they can get far bettter solutions to their problems for free elsewhere. They don’t need a eportfolio system to post thier resumes on.

So enough of letting assessment vendors tell us what facilities we will be forced to use in their walled garden, and expecting us to be excited about it. Enough with assessment vendors selling us “environments”. What we should be doing is describing the the enviroment that might exist – students using Wordpress, Blogger, S3, GDrive, email, messaging, etc. And then we should ask if they have a tool that can evaluate that. How will their tool interface with the learning environment we’ve constructed?

Anything else is insanity.

Where will the wave come from?

I love talking the theory, but it’s even nicer to see practical notes from people implementing solutions. From a recent post over here,  some Wordpress MU as class-space experimentation

Teachers are finding WordPress MU easy to use and I’m very happy to see that. Currently, Teacher Assistants are recording students as they read their writings in class using Audacity. We are using inexpensive mics with noise canceling, and I have to say, I’m impressed with how well they work. It’s not easy to cut out the ambient noise in a working first grade classroom.

That’s right. A first grade classroom.

I’ve been a frequent critic of primary and secondary education, and that’s unlikely to stop. But I’ve been impressed in the past year with how much faster things seem to be moving down there than up at the university level.

It’s not just scattered notes like the one above. The percentage of thought leaders in the Learning 2.0 space that are focussed on K-12 is extraordinary.

Why? One would think if you can run a blog and wiki with first graders that surely this should be cake for a university classroom.

More as a way to start this conversation, here are a few hypotheses:

1. K-12 (and particularly K-6) does not have the subject problem — there is no issue that writing belongs in one discipline, video in another, and history or math is seperate from each. Holistic approaches aren’t thwarted by an org-chart that divvies up the student.

2. K-12 is behind on the LMS wave, and having not been infiltrated by LMS vendors, they are more able to think out of the box, rather than in terms of what new LMS modules are available.

3. There’s just more teachers than university professors, which creates the critical mass needed to get a movement going.

4. They don’t have a developed IT department or large IT budget — and hence are able to experiment more with an ad-hoc bricolage of tools, especially free ones: i.e. technology decisions are not treated as budget decisions.

Those ideas are all possibly wrong — but I’d love to hear other takes on this phenemenon. Unless higher education gets its act together, it is quite likely the college freshmen of tomorrow will be entering a far LESS enlightened tech environment than the one at the high school from which they came.

Via bavatuesdays, I learn of CommentPress.

Obviously there are other non-WP group annotation tools. What’s really striking to me here, however, is how powerful the fit is between the CommentPress approach to text and the best bits of traditional literary exegesis.

So great is the fit, as a matter of fact, that I half wonder if CommentPress could become the first step toward faculty blogging — rather than the other way around…

The most invigorating job I ever had was working for CognitiveArts programming learning “simulations”. Founded by Roger Schank, CogArts was truly a company with a mission — to revolutionize education through technology rather than simply extend the current system. And we pushed the envelope in every way we could. I worked with a large team of programmers whose goal was to make the ultimate Choose-your-own-adventure multimedia learning experiences.

The core idea was simple: people learn by doing, so learning should simulate doing in a low risk environment. Schank’s favorite talking point was this “Which would you rather your airplane pilot have — 90 hours of the flight simulator, or 90 hours of book study?”

Simulations would generally lead a person through a “goal-based scenario”: perhaps as a Governor’s economic advisor they had to make decisions for a hurricane torn state on things like price controls and rationing, and observe the effects of the action. Perhaps they had to negotiate a house price as part of Harvard Business School Publishing’s Negotiation class.

The key to the system was failure-based learning paired with just in time instruction. Students would be encouraged to develop expectations about what would happen as a result of their actions. When they failed, they would be provided with context-sensitive instruction, and encouraged to try again. It had been shown in a number of studies  that by providing the bulk of the instruction after failure that you could get retention of information significantly higher.

The system was later copied (often poorly) by other corporate training companies, and is now a pretty standard offering of most custom elearning vendors (although I would argue that the desire of many vendors to push such modules into a one-size-fits-all assessment harness profoundly degraded the experience — at CogArts we built an LMS that was precisely tailored to the needs of our scenarios).

This autodidactic gaming approach to elearning seems miles away from the PLE and the Inverted LMS (I still haven’t quite resolved if those are the same thing yet — please excuse my transitional use of both terms). The Inverted LMS is inherently social and collaborative; the CogArts model was solitary and self-taught. Indeed, if there was one flaw with what we did at Cognitive Arts, it was probably that in the move from CD-based non-networked learning to web-based instruction we were not radical enough in our rethinking of the social element of education.

Despite that, I’d argue that simulations are very close to the PLE/Inverted LMS in theory. Why?

Because both focus on learning by doing. Where there is high-risk to real life failure simulations make a lot of sense. And where the definition of success in a field or task is very narrowly defined, simulations shine. The flight simulator, one of the first computer applications ever built, still remains the model here.

But the web has introduced us to plenty of low-risk ways to engage in disciplines. And that’s where the new approach comes in.

An example? At CogArts, one of the apps I admired most was the “Is it a Rembrandt?” simulation, which provided students with detailed pictures that could be faked paintings or undiscovered Rembrandts. The students, through learning about Rembrandt’s style, had to make the call. Experts were there to give them the just in time instruction should they fail — explaining this or that about brush strokes or subject matter.

I’d still pay good money to use that sim — I think it remains a wonderful way to learn, and one that appeals to our gaming culture. Put software like that in a current high school, and you’re going to blow the doors of education. In a good way.

But what is striking nowadays with the web is how it supplies plenty of real low-risk problems for students to engage in. The Rembrandt simulation was built during a mid-90s rash of discoveries that certain Rembrandts were fakes. Ten years later if such a thing happened, there’d be a good chance you could get hi-res photos of detail from the fakes, if you asked nicely.

So what happens then? You gather your students, you put up a wiki and series of student blogs, you roll your sleeves up, and you get your class analyzing the paintings. Google becomes your just-in-time learning application, which is cool, because that’s what your JIT solution will end up being in real life. Success or failure is determined, as in life, somewhat fuzzily by the reaction of the experts in real life: if you can get them to engage with your work at all, that’s a high level of success; if they actually start agreeing with you or noting things as valuable insight, even better.

I miss both producing and playing with the Schank software, just because of how much fun it was, and if I could buy those titles shrink-wrapped from the local Staples today, I’d spend my own money to buy a title a week. Heck, I may go home tonight and play the Cable & Wireless simulation, which I still have a disc of somewhere. In a perfect world the government would fund more of these sorts of simulations.

But the brilliance of the internet is how much it matches, for a certain subset of problem, the perfect learning environment CogArts was simulating in its courseware. As with the simulations, on the internet you can try out ideas without much risk, you can get information from Google on a Just-in-Time basis, and you can talk to experts about the validity of your decisions. And, yes, it’s a lot fuzzier, and I certainly don’t want my pilot to have put in 90 hours of BLOGGING, but for certain types of learning (and possible for most learning), it’s a preferred method of engagement.
