That’s not what happens in Wijnands’s classes, though. “See,” he says as the students burst into the room and hurry to their desks—oddly, without sitting down. “I don’t do anything.” It’s 8:30 a.m. on a normal Wednesday in September, and Wijnands’s classroom does not look like one. None of the desks are in rows facing the front of the room. Instead, they’re positioned so groups of four students can face one another.
