Intended to assist educators and trainers who must make recommendations about facilities to architects and school authorities, this ERIC information analysis project summarizes research on the design of both classrooms and individualized learning spaces that will optimize learning. Six teaching/learning space topics are considered: (1) light and color; (2) heating, ventilation, and air conditioning; (3) acoustical and background noise; (4) furniture and ergonomics; (5) electrical wiring and conduit requirements; and (6) computer requirements. The relationship of physical properties of learning facilities and behavioral science data is considered, and the specific environmental variables that influence the student--temperature and humidity, noise, light and color, seating position, classroom design or openness, density and privacy, and the presence of windows--are discussed. Research findings on requirements for materials storage, minimum light for learning spaces, colors and learner activity, and ideal temperatures for student activities are summarized in four tables, and diagrams of classroom space configurations for various audiovisual media are provided.
