Do children have anything to teach teachers? Jean Piaget believes that they do. As a beginning teacher, I focused on elaborate preparation of explanations and demonstrations on content. To piaget and his co-workers I owe a special debt for their ingeneous methods of exploring children's thinking and their theory of intellectual development. A study of Piaget's work, together with direct observations of children, has been instrumental in my transition to another stage of development as a teacher.' -Ed Labinowicz
