How do children learn? How are they taught? These are two fundamental questions in education. Caleb Gattegno provides a direct and lucid analysis, and concludes that much current teaching, far from feeding and developing the learning process, actually stifles it. Memory, for instance, the weakest of the mental powers available for intelligent use, is almost the only faculty to be exploited in the educational system, and holds little value in preparing a student for the future. Gattegno's answer is to show how learning and teaching can properly work together, what schools should achieve, and what parents have a right to expect.
