In an NPR interview with Philip Sadler of Harvard:

“Students are not empty vessels,” he says. “Students are full of all kinds of knowledge, and they have explanations for everything.” From birth, human beings are working hard to figure out the world around us … cognitive science tells us that if you don’t understand the flaws in students’ reasoning, you’re not going to be able to dislodge their misconceptions and replace them with the correct concepts …

Teachers who find their kids’ ideas fascinating are just better teachers than teachers who find the subject matter fascinating.”
