Free Range Learning

Threshold Magazine (which is part of Cable in the Classroom) has a recent issue out that is devoted to new media literacies and learning in a participatory culture. Much of it was written in conjunction with the New Media Literacies Project at MIT, which is Henry Jenkins' old haunt. While the articles are focused primarily on the K-12 context, they're pertinent to higher ed as well.

A previous issue of this same journal has a number of interesting pieces related to learning online.
