I tried a couple of things for back channel use in class. Some groups are doing review and I thought it might be useful for students to be able to post queries and help each other work out answers to problems. I tried using todaysmeet first. This didn’t work as the thread would get very untidy very rapidly. If someone asked a question, the answer would not be associated with it. It also took too much policing as it wasn’t clearly useful.
I thought wallwisher might help with the issue of associating questions with answers. Turns out it functioned so slowly with the group we simply abandoned this one.
Basically, I think this is an idea that doesn’t fit my classroom very well – I would rather have people just talk to each other. The idea that the conversation could carry on beyond the room would only work if it involved something like facebook pages.
