This report reviews the research on school and classroom environments, discusses the implications of such research for the design and evaluation of secondary school programs, and provides an annotated bibliography of the relevant literature. Topics discussed in the review include: (1) the semantics of school environment research; (2) the structural basis for concepts of multiple environments in schools; (3) the relationship between environments and educational outcomes; (4) the relationship of adolescent attitudes and behavior to educational environments; (5) the importance of extending urban secondary school reforms into the community; and (6) new knowledge and issues addressed in the 1970s that suggest directions for secondary school reform. The attached annotated bibliography provides approximately forty citations of published works that deal with plans for reform and research of urban secondary school and classroom environments and their effects on students.
