What is a wiki? Well basically it is a website that can be changed and update, the one that you have probably heard of is Wikipedia. When changing a wiki the revised version become the current version. But you can track the history of the document as it is revised becuase the older versions of the document are stored.
Wikis are becoming more popular in a classroom. Students can use them to share data or research. They can also be used for students to work in groups. But they aren't only useful for students teachers can use them too. Teachers can use them to "collaboratvely author the structure and curriculum of a course."
I think I would have my students use wikis to work together for groups projects.But I don't suggest they use them as a source of research because they can be changed the facts might not be correct.
