Here’s a thought that occurred to me this week. I’ve read hundreds of scholarly books and written one. But I’ve been in the classroom maybe a thousand hours so far, and I’ve seen other people in my department teach for maybe two hours, tops. The only exception is team teaching, which I’ve done once before and am doing again this semester. Planning a class and actually watching a colleague teach at length is really eye opening, and gives me all sorts of new ideas for teaching.
