In response to Rolling's questions I thought it might be useful for others if I describe the process as I try to design and implement a class blog for my college English Composition classes. This seems like a better use of my spare time than the hours I waste playing Call of Duty when I should be doing lesson plans or learning how to be a good composition teacher.
My goal for the class blog is twofold. I am hoping that having a single blog for which everyone is a contributor will help to foster idea sharing and a sense of community among the class members. In a perfect world, students will read what other students have written and incorporate that into their own posts. In addition to that, I'm hoping that the blog will function as a big repository of rough ideas that students can use when they can't think of anything to write about.
There is also the fact that my composition students don't get a ton of variety in their official "papers:" three types of summaries and three types of summary/evaluations. So hopefully this will give them a chance for some less formal writing.
I had a lot of trouble deciding how to sign students up. I finally decided that I would do the following: for each class I made a wordpress blog for each class and I'm going to send an invite to the student emails (every student gets an email through the college). That way, all they have to do is give themselves a screen name and they will automatically added to the correct blog as a contributor.
We'll see how it goes. I'm not going to start the process until next week when the roster will be finalized and the introductions will have been gone through.
