This study focuses on Thornlea Secondary School's social relationships and the way in which they affect the implementation of innovation. The study is largely descriptive and utilizes taped interviews of students, teachers, administrators, and citizens of the community as the primary source of information. The study's concern about innovativeness centers on both the frequency of innovation and the quality of specific innovations. One chapter provides the background and traces the events that led to the establishment of the school, and another chapter discusses the problems associated with the objectives of the various groups in the school. Two other chapters analyze the administrative and social structure of the school and describe various specific innovative practices that have been adopted. In the final chapter, the main implications and conclusions of the study are identified. A descriptive overview, issued by Thornlea for parents and prospective students, is reproduced in the appendix. (Author/DN)
