Many of us already make adjustments to class activities in real time based on student response, whether it’s by watching faces/body language to get a sense of what they’re understanding, using clickers, or using some of the free “backchanneling” apps available to get students actively involved in lectures (e.g., PollEverywhere, Kahoot!, Socrative). But sometimes the possibilities are overwhelming. It’s hard enough to pick up on the physical cues of student engagement and integrate them in real time; harder still to layer on some of these technologies and use them well.
