This 3-year program has three goals: (1) to devise a curriculum for disadvantaged 4-year-olds, (2) to develop a model for introducing new curriculums into a school setting, and (3) to develop parent group-work programs to foster achievement, inner control, and cognitive development in the child. The sample consists of 50 Negro and 50 white (including 50 boys and 50 girls) each year. The curriculum includes work in inner control, is based on Piaget's operative and figurative aspects of knowledge, and uses a modified Bereiter method for language patterning. The second goal was achieved by involving the teachers in curriculum development and using a supervisory team to help teachers effectively practice the curriculum theories through an orientation and inservice training program. In the parent group-work program, two experimental groups met in three sessions studying behavior modification, inner control, and cognitive development. A control group went to P.T.A. meetings only. The program's goals will be evaluated on its short and long term effects on the children and its general effects on parents. Dissemination includes observations, reports, and conferences. Tables and a bibliography are included. (JS)
