"Mr. Erma’s school is a showcase campus. Last summer, at a conference in Peru, he spoke about adopting Finnish teaching methods. During a recent afternoon in one of his school’s advanced math courses, a high-school boy fell asleep at his desk. The teacher didn’t disturb him, instead calling on others. While napping in class isn’t condoned, Mr. Erma says, “We just have to accept the fact that they’re kids and they’re learning how to live."
