This final report is a general description of the activities of the Demonstration and Research Center for Early Education (DARCEE), an Appalachian preschool program for disadvantaged children. Included in the document are: a general overview of the program, histories of the three Early Training Centers, and objectives and publications of the DARCEE Information Office. DARCEE's direct service has been to demonstrate research, and train individuals to promote the educability of young children from low income homes. DARCEE has worked intensively with 135 families in periods varying from 8 months to 2 1/2 years. Most of these families (with the exception of 25 mothers of infants) have had several children present in the home. In addition, 140 children have been enrolled in DARCEE classroom programs for periods of one year each. The report of the dissemination office, which includes writings, public presentations, and mention of the 4500 visitors, shows the broader impact of DARCEE. The work on the diffusion of training effects within a family, and above all, work with parents, have suggested cost-efficient training models. (Author/MS)
