Dr. Barfield is a professor in Health & Human Performance. As a result of the 2013 Faculty Technology Institute he implemented AirSketch in his classes.
I use Air Sketch in kinesiology and personal and community health (summers) and plan to begin using in biomechanics class. The Air Sketch (app) allows me to make notes on PowerPoint slides in real time and can even have the students participate (by having them write on the slides). It is especially helpful when I walk around the room and can make points from anywhere (without being tethered to the teacher station by a cable). I think the students think it is cool too the I can actually use technology, simple as it may be.
