This three-part report discusses the concept of intelligence and its importance for educators. Part 1 considers the basic question of what intelligence is. Part 2 discusses the implications of notions of intelligence for schooling, dealing with both the training of content knowledge and the training of intellectual skills. Each of these first two parts is divided into sections which discuss the psychometric view, the Piagetian view, the information-processing view, and comparison and evaluation of alternative approaches. Part 3 presents an outline of a program of instruction for intellectual skills, based upon a particular theory of intelligence. A bibliography is included. (JM)
