Technology Tools Wiki
I spend the weekend setting up a wiki about Technology Tools that are useful for educators. Check it out at http://wiki.usask.ca/db/index.php/Main_Page
Wikis are useful for keeping online class resources easily available to students, but their most powerful use is in collaborative projects because team members can share ideas/research, and edit team projects without having to meet face to face.
A wiki available to an entire class is a great way for faculty to increase their own knowledge of online resources as students add their research to the site.
