Teachers are amazing, but they're not superhuman ... Michael B. Horn is a speaker and the author of several books, including the award-winning "Disrupting Class: How Disruptive Innovation Will Change the Way the World Learns." "We've spent the last century-plus adding new responsibilities to a teacher's job," he says. "Every few years, we identify a new social ill ... and we say, 'Schoolteacher, that's now your job.' That's hard for a teacher. Turns out teachers are not super-human. They're people. Asking them to do all these things is a struggle. It can lead to burnout. That's a source of seeking to do things in different ways. To make their lives simpler and manageable." Listen as Michael and host Levi Belnap discuss innovation in education.
