Yesterday I posted a “Twitter Matrix” for education, which generated a fair amount of buzz in the micro-blogging world. A few people sent me messages asking if I could explain how I make my class backchannel, so here goes.
First of all, I think of the backchannel as the conversation that might otherwise normally happen in class within students’ minds, or between each other. It’s the communication that happens between two or more students about their experience of class and their own learning. To be clear, classes have always had backchannels of conversation, the difference now ist that technology allows us to put them to better use. When these conversations become public, students and teachers have an opportunity to learn from each other, and questions get answered, and issues get addressed.
