When designing schools, one should assign space for athletic fields, arrange halls so that traffic will not disturb classrooms, separate grade levels, provide playgrounds exclusively for younger children, and provide lighting and ventilation. Unit plans should be designed so that all educational and domestic activities can be executed in the vicinity of the classroom, the classroom can adjust to changing studies, and the classroom provides uniform environmental conditions. Housing development ideas include the neighborhood unit theory; joint use of schools and their facilities; the open school concept; and sharing a school common area. Modules and systems building are economic techniques for school construction. Multipurpose open spaces and conceiving of the school environment as a means for learning are essential elements in school architecture. V-type organization facilitates adjustment to different subjects, as well as individualized and autonomous learning. The construction of open schools is no more expensive than that of conventional schools. The issues involved in the planning process include constraints, educational demands, noninstructional demands, and community demands. Included are 36 illustrations (13 of which are floor plans), 1 table, and 10 photographs. (RG)
