Hi Rob! Thanks so much for your insightful observations. It's so true that floating or getting physically into the learning environment, as opposed to behind a lectern or desk, is crucial to student engagement. I might suggest also varying your lectures/presentations with related mini-activities that could further engage students in the learning process. There is an old saying about the "seven-minute rule" - change the presentation/interaction stimulus about every 7 minutes to help keep students from drifting or shutting down.
