Ryan Cordell and I had been exchanging tweets on the use of blogs, wikis, and the like in class. Since 140 characters is good for many things, but not this, I promised him I’d write up a quick description of the practice I’ve developed over the last few years.
The context for this is the Moodle Learning Management System (LMS), which I’ve been using in its 1.x and 2.x versions. There’s no reason why you couldn’t do this with loose wiki, blogging, and microblogging systems. But I’m still reluctant to require students to release their school work publicly.
