Producing music, producing knowledge

What is knowledge and how is it produced are pretty important questions in the KPS space. When I grew up, knowledge was something that you had, more or less, in your head. To some extent there is still an element of this today but, IMHO, that is much reduced in its importance as about a billion folk set participate in all manner of conversations and debates using various bits of so-called Web 2 software to produce knowledge. As David Weinberger of Everything in Miscellaneous fame, has argued in a number of podcasts, knowledge resides in the conversations, the email lists, the blogs, the wikis. Of course, you don't need the online stuff to do it as the post from Edutopia flags. The creative arts have always been a place to look to find KPS-like stuff happening. More often than not the teacher is also a practising artist and is thus well placed to articulate what goes on in the classroom with what goes on in the world outside.
