This seems like a cool thing:
An open, connected course on Design Based Research, hosted by the Digital Media and Learning Commons which, according to an email I got through the xmca list, is a recently launched space funded by the MacArthur Foundation and managed by Mimi Ito. The course runs from March 23-May 31, and has a bunch of neat guest facilitators. I'm assuming the materials will still be available after the course is over, but I couldn't find confirmation of that. I hope so.
