Q: What platform would your recommend for an educator who wants to share his/her teaching practices online?

A: The best way is to create the educational video and distribute it at TED-Ed:

http://ed.ted.com/about

TED-Ed’s commitment to creating lessons worth sharing is an extension of TED’s mission of spreading great ideas. Within the growing TED-Ed video library, you will find carefully curated educational videos, many of which represent collaborations between talented educators and animators nominated through the TED-Ed platform. This platform also allows users to take any useful educational video, not just TED's, and easily create a customized lesson around the video. Users can distribute the lessons, publicly or privately, and track their impact on the world, a class, or an individual student.

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
