REPORTS FROM SEVERAL SCHOOL DISTRICTS ON THE USE OF AND PLANNING OF LANGUAGE LABORATORIES ARE PRESENTED. LABORATORIES SHOULD BE ARRANGED FOR FLEXIBLE USE. THE AVERAGE HIGH SCHOOL STUDENT CAN USE A LAB PROFITABLY FOR 20 TO 25 MINUTES. THERE ARE THREE DIFFERENT TYPES OF LANGUAGE LABORATORIES THAT ARE DESCRIBED. THE SATELLITE LAB IS DIVIDED BY A…

In order to serve college administrators, architects and physics educators, a collection was made of material reflecting the state-of-the-art of physics building design. This body of material, including drawings, diagrams, and photographs, resulted largely from extensive interviews with about 50 institutions who had recently built such facilities.…

In recent years, the use of laboratory animals for bio-medical research has shown marked increase. Economic and efficient housing is a necessity. This two part report established guidelines for design and selection of materials for conventional animal housing. Contents include--(1) production and breeding facilities, (2) quarantine facilities, (3)…
