The purpose of this program was to help disadvantaged preschool children overcome some of the handicaps which hindered their educational, social and emotional development, to increase the interaction between the home and school, and to make the teacher sensitive to the particular needs of his disadvantaged pupils. The program, which operated in four North Philadelphia, Pennsylvania, elementary schools, was staffed by home-school coordinators, social workers, regular teaching staff, and student volunteers from Temple University. Three of the 4 home-school coordinators lived in the neighborhood of the school. Moreover, parents were encouraged to participate as teacher aides in the classroom or on field trips. Home-school contact was further strengthened through parent conferences and a health program. Featured in the instructional program were learning experiences to develop the child's language facility, visual and auditory discrimination, and ability to pay attention. Other educational experiences were designed to enhance the child's self-image and to increase his knowledge of basic scientific, mathematical, social studies, and health concepts. Followup research was conducted to determine the impact of the program on pupils' social and intellectual functioning and on their attitudes toward learning and testing. (LB)
