Colleges need appropriate large group instructional facilities for effective and efficient use of instructional aids and media. A well planned system of facilities must provide space for learning; production, origination, and support; storage and retrieval. Design begins with a building plan--a statement, made jointly by the administrator and policymaker, to translate philosophy and goals into specific building requirements. The architect designs a facility to meet the requirements. He must take into consideration factors such as optimum viewing area, seating type and arrangement, and building codes when deciding on room shape and capacity. The need for flexibility, adjunct service areas, and an integrated system for aids, media, and instructional methods must also be considered. A centrally located, remotely controlled projection area, a single large television screen, a display surface, sloped floors and a coordinated color scheme are desirable. Windows constitute an unnecessary distraction, so adequate air conditioning is a necessity. Lighting, acoustic treatment, and sound insulation must be coordinated with the mechanical and structural elements of the design. Eleven design studies are presented. An experimental classroom at Rensselaer Polytechnic Institute and some communications centers are discussed. (JY)
