Tyler DeWitt: Hey science teachers — make it fun

High school science teacher Tyler DeWitt was ecstatic about a lesson plan on bacteria (how cool!) — and devastated when his students hated it. The problem was the textbook: it was impossible to understand. He delivers a rousing call for science teachers to ditch the jargon and extreme precision, and instead make science sing through stories and demonstrations. (Filmed at TEDxBeaconStreet.)
