A Piagetian Method of Evaluating Preschool Children's Development in Classification.
Kamii, Constance; Peper, Robert
A preschool curriculum for lower class children was developed based on Piaget's theory. Evaluation procedures were developed to parallel a Piagetian curriculum. According to Piagetian theory, the mechanism of classification is the coordination of the intensive and extensive properties of a group of objects. The ability to dichotomously classify all objects in a group occurs at a rather high developmental level, attained in four stages delineated by Piaget, and discussed at length in this report in relation to the development of logic. In a nonncontrolled experiment, Pre- and posttests were given to 23 disadvantaged white and black nursery school children using three sets of objects. These scores were compared with scores of 16 middle class nursery school children. The Piagetian exploratory method was used, allowing the examiner to help the child to understand the questions. It was concluded that curriculum significantly increased the children's ability to make both first and second dichotomies and to shift criteria. The middle class children's classificatory ability remained at the same level. Both groups progressed in their ability to give verbal justifications. With suggested modifications, the testing method seems valuable because it evaluates the ability to coordinate both intension and extension. (NH)
