The Wonderful, Wacky World of Wikis

I enjoyed tonight's class, mainly because I'm so enamored with wikis right now. I'm working to get one up for my mentor teacher, though we've already run into a technical roadblock. I think the possibilities are endless--I particularly like the idea of posting a wiki for each new unit, so it becomes a collaborative clearinghouse for students to return to for discussions, links to other resources, study/test prep;etc...I'm sure there are other ways to do this, but if a district doesn't have a Blackboard type of set-up, it seems like a cheap, relatively easy way to get at the same basic set up. Some people seem concerned with confidentiality, but for that, there's always email or google docs, and besides, I look at it like hanging students' work up in the classroom--it's a way for them to show off what they can do, and if they're self-conscious, they can either edit it or request that the teacher take it down. This is something I will most definitely be using, probably more than anything else we've worked on so far (except for Thinkfinity).
