In defense of the lecture as a method of teaching.

"Listening continuously and taking notes for an hour is an unusual cognitive experience for most young people. Professors should embrace — and even advertise — lecture courses as an exercise in mindfulness and attention building, a mental workout that counteracts the junk food of nonstop social media. More and more of my colleagues are banning the use of laptops in their classrooms. They say that despite initial grumbling, students usually praise the policy by the end of the semester."
