The educational park environment that the District of Columbia schools are planning is seen as a learning environment consisting of a cluster of facilities, services, technological resources, and staff, and operating within a flexible administrative structure conceived and designed to optimize the advantages of the economies of size. The study, financed by a Title III, ESEA grant, indicates that the establishment of such a park for 18,000-20,000 students from early childhood to grade 12 would be advisable for Washington, D.C. Educational data related to this report are contained in a series of appended tables and graphs. (Author/MLF)
