Since 1985, the National Crime Prevention Council and the National Institute for Citizen Education in the Law have collaborated to support the implementation of the Teens, Crime, and the Community (TCC) curriculum in schools, community-based organizations, and juvenile justice settings. The curriculum is intended for youth at seventh- through ninth-grade levels. TCC combines education and action and focuses on prevention and student responsibility. This report covers two evaluation activities: the revision and field testing of student knowledge, attitudes, and behavioral instruments and a student impact assessment. The two program models selected for evaluation were TCC as an infused unit in ninth-grade civics and TCC as a ninth-grade social studies elective. The impact assessment included 218 full TCC students, a control group of 173, and 38 using only the textbook. TCC students increased their correct posttest answers and had an increased level of social bonding on the posttest. The TCC group exhibited an overall decrease in mean frequency of delinquent acts. Using the book alone increased knowledge, but did not affect attitudes and behavior. Seven appendixes discuss methodology, the pretest and posttest, and the study protocols, and present data tables. (Contains 15 tables and 16 appendix tables.) (SLD)
