Backchanneling is a digital conversation that runs in the background while a face to face activity is occurring. This gives students an opportunity to engage in conversation at a different level.
5 WAYS BACKCHANNELS GET STUDENTS AND TEACHERS TALKING
In the example below, the teacher has created a "backchannel" using the Conference tool in itslearning. In this case, the students are viewing a video covering the water cycle. While watching the video, the students can join this conference by clicking "Start conference in new window". The students can ask questions, post comments and interact actively with what's happening in the video instead of being passive viewers.
