Wikis in Education

[Helen W]

I'm in the process of writing an article about the uses of wikis in teaching and learning. I'm particularly interested in wikis in Higher Education, but any examples from any level of education, schools too, and FE, is welcome. If you can help - if you've had a wiki project (successful or not), or know of interesting projects, resources, website, could put me in touch with someone else who has information about wikis, please put the information in this forum.

Do you think wikis are useful in the classroom (virtual or real)?
