THE NATION'S SCHOOLS SCHOOL OF THE MONTH IS A BUILDING DESIGNED WITH AN OPEN INTERIOR. THERE ARE NO SEPARATE CLASSROOMS. THE MAIN SPACE IS DIVIDED INTO THREE LEARNING AREAS, PRACTICAL ARTS, ADMINISTRATIVE, AND COMMONS. FLEXIBLE PARTITIONS AND MOBILE CHALKBOARDS ACT AS VISUAL BARRIERS TO LIMIT DISTRACTIONS WHILE CARPETING AND ACOUSTIC BAFFLES REDUCE NOISE. HEAT GENERATED BY PEOPLE AND LIGHTING SUPPLEMENTED BY ELECTRIC COILS KEEP THE BUILDING WARM--AIR CONDITIONING COOLS IT IN THE SUMMER. THIS ARTICLE IS A REPRINT FROM NATION'S SCHOOLS, AUGUST, 1967. COPIES MAY BE OBTAINED FROM MCGRAW-HILL, INC., 330 WEST 42ND STREET, NEW YORK, N. Y. (BD)
