Teaching Naked

Wow!  I've been mulling over the idea of teaching naked, the last couple of days since I first saw this posting on Dean Sharski's blog.  My initial thoughts were wait a second.  Content is supposed to be what we're all about in schools.  Then Jose Bowen turned up again on the NPR all tech considered podcast, and I started to more fully understand his ideas about turning learning around.  He contends taht students come to class without any understanding of the subject, listen to a lecture, study like crazy and try to show that they understand.  Instead, he proposes a model where students listen to the lecture ahead of class, take a quiz or some other assessment to show that they listened to the material, and then discuss and explore the content in class.  As he states in the video above, most lectures last for 48 minutes and then have 2 minutes of questions, this way he can offer the same content and fifty minutes of questions.  To me these are powerful ideas.  I've already shared them with our high school faculty.  Several of the teachers are interested in giving it a try.

Then I drilled into Jose Bowen's site a little and found a set of podcasts that serve as the listening ahead of class for hs hstory of jazz course.  I listened to the bop and hard bop podcasts. I was struck by the fact that at the beginning of this podcast, he launches in right away noting that any categories are provisional, and this is just one way to organize and categorize the whole movement of Hard Bop.  Reminded me right away of David Weinberger and Everything is Miscellaneous. Very interesting ideas.  Even Bowen's old courses at Georgetown look like they built on diverse ideas. Anyone who can incorporate Wagner into a course on politics and culture has a lot of interesting thoughts.

Taxonomy of Knowledge

David Weinberger's video (based on his new book Everything is Miscellaneous) represents a whole series of new powerful ideas. Equaly interesting are his series of interviews with physicist Neil DeGrasse Tyson, Markos Moulitsas ZĂșniga(founder of he Daily Kos), Arriana Huffington (founder of the Huffington Post), Jimmy Wales (co-founder of Wikipedia).
The main threads running through all of these is how everything has changed. "Web 2.0 changes everything" is a common rallying cry among Educational bloggers, but the how is often missing. I believe that David Weinberger is starting to put his finger on it. According to him, there are three orders of data. There is the data itself, say the pictures in an archive. There is metadata, the card catalogue. But when data and metadata are digital, they become interchangeable. For example, if you know that Charles Dickens wrote a Tale of Two Cities, you can Google and the four or fifth hit gives you the text of the A Tale of Two Cities. Conversely if you knew the line, "It was the best of times, it was the worst of times", but were unsure of its source, you can Google the phrase and see that it was written by Charles Dickens. Weinberger's important observation is that metadata is what you know. Data is what you don't.
In terms of Web 2.0, Weinberger mak. es two observations. Firstly that all taxonomies are arbitrary. There is no perfect order, waiting to be revealed. If everyone can organize their own knowledge in any way they see fit, that is incredibly liberating. The Web 2.0 tool that allows users to do this is tagging. As I was writing this I realized that tagging is a constructivist tool. It allows people to attach their own meaning.
Secondly, he notes that traditionally editors have exercised power by controlling what goes on the front page of a newspaper. Thanks to Web 2.0 tools, everyone is their own editor and can use tools like NetVibes to pick what stories they want to see, and in what order. To me that is a revolution on par with Martin Luther's "Every man is his own priest," and sums up very well how Web 2.0 changes everything.
