Four schools were visited in an attempt to assess the merits of combining several classrooms in a large space as a method of school construction. Interviews with students and teachers as well as personal impressions form the basis for evaluation. Satisfactory results were found for schools-without-walls, school carpeting, acoustic control, team teaching, and nongraded systems. Special considerations include minimum use of space dividers, isolation of office and foreign language areas, hard floor surfaces for wet construction areas, and inclusion of gymnasium and instructional movement center. Report includes detailed analysis of four open plan schools and description of a typical nongraded program. (MM)
