I realized something strange was happening. The room was silent, and students sat in their seats with chips, fruit, and soda—all laptop lids were up, and earphones in. I asked students to look up and examine what they saw. I told them that when I had offered this opportunity the previous year, the room was noisy and filled with student banter, jokes, and eye-to-eye engagement. Did they see a problem with the fact that we were having a "party," but they weren't talking to each other?
