Let’s suppose behavior in schools is as good now as it’s ever going to be. How good can schools be if we just assume that children’s behavior during the day will range from extremely annoying to delightfully charming depending on what’s happening and whose point of view we adopt? Can we start from here and see how far we can go with learning and achievement if we applied to curriculum delivery issues the same resourcefulness we’ve allocated to behavior problems? Control in the Classroom begins with this premise and applies the scientific explanation of behaviour, Perceptual Control Theory, to the matter of curriculum delivery. Teachers will appreciate the clear guidance and numerous examples to help them organize their classroom instruction so that everyone in the class has the opportunity to achieve the goals that are important to them.
