You must not do “chalk and talk” at the blackboard. You must have a “workshop” in every single reading period. Your students must be “active learners,” and they must work in groups. As one circular distributed to principals put it: Your teachers must transform themselves from the “sage on the stage” to the “guide on the side.”
