This document discusses using backchannel technologies to enable in-class collaboration and feedback. Backchannels allow students to ask questions, respond to polls, review questions and answers from their peers, and make notes during a lecture. This provides benefits like rapid feedback, reinforcement of concepts, and a sense of community. It also benefits educators by supporting engagement, reducing clarification questions, and providing analytics on engagement and retention issues. The document recommends several resources on using backchannels and their impact on inclusive teaching and active blended learning.
