This report describes the Cognitively Oriented Curriculum based on Piagetian theory which is used in the Perry Preschool Project. The purpose of this long-term project is to help educationally disadvantaged Negro children develop the concepts and abilities necessary for academic success. The Piagetian theory of cognitive development is discussed with reference to the main premise underlying the Cognitively Oriented Curriculum; i.e., there cannot be a basic understanding of self and world without the ability to place the self in time and space and to classify and order subjects and events. Teaching techniques and teacher attitudes are discussed, with emphasis placed on an orientation in which the teacher identifies Piagetian learning goals, observes the children to determine operant levels, and plans sequences of activities which best implement these goals. Other specific topics covered are: classroom routine and equipment and their importance to the curriculum, language learning, sociodramatic play, and planning the curriculum. Home visits are described in terms of teacher and parent response, and implementation of the program. An extensive classroom activity guide and sample daily schedules and commentary are included.
