"Teaching as the direct delivery of some preplanned curriculum, teaching as the orderly and scripted conveyance of information, teaching as clerking, is simply a myth.
Teaching is much larger and much more alive than that; it contains more pain and conflict, more joy and intelligence, more uncertainty and ambiguity. It requires more judgment and energy and intensity than, on some days, seems humanly possible.
