A floor plan accompanies each of six chronologically arranged schemes for housing educational programs. Scheme A represents the in-line corridor plan whose main characteristics are--(1) double loaded corridors with fixed bearing walls, (2) single window walls providing minimal light and ventilation, and (3) small classrooms with fixed desks and limited equipment. The finger plan of scheme B provides bi-lateral daylighting and cross-ventilation through use of exterior sheltered walkways instead of corridors. Scheme C, the economically based back-to-back plan, is characterized by--(1) open peripheral corridors, (2) single window walls, and (3) the potential for flebility. Scheme D modifies the back-to-back plan by introducing folding partitions between classrooms, improved mechanical systems, and shared team teaching preparation space. The cluster plan of scheme E groups 4 to 6 classrooms about a central activity area. It is characterized by flexibility and dependency on artificial light and ventilation. Scheme F represents the modular space shell which provides for new information media in a flexible, mechanically integrated environmental shell. (MH)
