"What is the name for the part of our ear that vibrates when it gets hit by a soundwave? Anyone? Anyone? Bueller? Bueller?" We all know the scenario. But what's the best response? And how do teachers actually respond? This article offers best practice ("cold call, wait three seconds before asking a student to respond, correct wrong answers, and offer a hint") and, more interestingly, looks at five ways teachers go wrong. What also struck me was my own reaction - thinking that this sort of article (or data supporting this sort of research) will go in to training future automated tutors.
