I guest lectured at Fanshawe College this morning. In presentations in classroom settings, I have recently found myself opting for the whiteboard and marker over the projector and slidedeck. I have an untested, anecdotally-based hypothesis that people are getting tired of looking at screens all the time. Maybe we are unconsciously intrigued (and reengaged) when someone starts doodling, scrawling something imperfect in real time? I wonder if there is a tipping point where the ‘non-digital’ becomes a ‘special, attention-grabbing feature’ in education and communication?
