A nice back-channeling story

What is backchanneling? Imagine being able to talk and ask and answer questions that were arising from watching a video or listening to a speaker. Imagine it being done in a "chat room" of some kind and not orally. That is backchanneling.

This is one of the best descriptions of a class period in whcih the students tried their hands at this kind of learning. Chris Webb is the author. Give it a read.
