Q: I'd like to create Wiki page for my class. How do I start?

A: Wiki  proved to be a great tool for collaboration. You can request Wiki through ASU Blackboard: http://help.asu.edu/sims/selfhelp/SelfhelpKbView.seam?parature_id=8373-8193-4586 

or build your own outside of Blackboard.

Here is the link to a brief response and resources: https://educators.pbworks.com/w/page/18697857/StudentWikiAssessment
The advantage of using Wiki instead of Google documents is: you can track individual contribution of the student to evaluate his/her participation in the collaborative project: http://community.wikia.com/wiki/User_blog:Meighan/Tracking_Contributions:_Recent_Activity
