The author, working with a 4-member teaching team, sought to determine how a group of pupils and their teachers would respond to an open space program proposed for a new senior high school building. A test program was conducted in temporary quarters with an experimental group of 25 randomly selected seventh grade students and a control group of 25 students from the regular junior high school building. The Comprehensive Tests of Basic Skills, administered to both groups, showed no significant differences in cognitive achievement between the groups. An attitude test, drawn up by the teaching team and administered to the experimental group only, showed a high level of favorable student attitude. The teachers found both advantages and disadvantages in the open space arrangement, but that the disadvantages were largely of a nature to respond to corrective measures. Those people involved in planning, implementing, and evaluating the open space program concluded that it warranted expansion into the new building, but that study of the concept should be continued, using additional methods of evaluation.
