I personally like Wikispaces, which, by default, has a discussion board attached to each page. That could be good to ensuring that discussions between students about changes, are tied to a particular page, rather than getting lost in other discussions/ emails that they're having. I've recently been to ALT-C - a conference in the UK for Learning Technologists. One of the papers ( http://www.alt.ac.uk/altc2007/timetable/abstract.php?abstract_id=1220 ) looked at how students were using wikis etc. They found that students found the group work aspects very difficult, and the most common way of creating a wiki was for them to divide up the content and create a "page" each. Reference was made in the presentation to a different session, when "Wiki etiquette" was discussed (not sure which session, as i didn't go to it). They made the point, however, that they'd spend a lot more time discussing how much work most students need to help them effectively use a wiki. (The presentation doesn't seem to be linked to from the page. Others that I went to were, so hopefully this one will appear at some point) I know that when I had students creating wikis, they were definitely of the "I'll do that page & you do that page" variety. So, getting them to understand what a wiki really involves is, I think, going to take quite a bit of work. -- New URL: Blog: http://userweb.port.ac.uk/~duke-wie/blog/
