In the spring of 1970., the Policy Institute of the Syracuse University Research Corporation was "asked to investigate the causes of violent unrest and educational disruption in a fair sample of the nation's urban high schools, and to identify strategies that appeared to be successful in mitigating the worst of the troubles. This report is the result of an in-depth analysis conducted by the Policy Institute staff. The data collected involved approximately 60,000 students from 27 public secondary schools selected within 19 large cities. Interviews were also conducted with administrators, teachers, parents, community people, police and district officials. Questionnaires were completed from secondary schools in the United States that met certain criteria. A copy of the questionnaire, statistical tables, bibliographies, summarization of findings and recommendations for policy-making are included in this final report. (LS)
