So the professor developed a backchannel tool that allows students to submit questions online during class and receive real-time answers from a teaching assistant. Question-askers remain anonymous to fellow students, but Samson and his TA can see their names. As Samson suspected, students had plenty of inquiries when offered an alternative method to raise them.

They found that the use of the backchannel dramatically increased student inquiry in class.
