The booklet is part of a grade 10-12 social studies series produced for bilingual education. The series consists of six major thematic modules, with four to five booklets in each. The interdisciplinary modules are based on major ideas and designed to help students understand some major human problems and make sound, responsive decisions to improve their own and others' lives in the global society. Students are taught to: (1) comprehend and analyze the issue and synthesize their understanding of it; (2) effectively interpret the topic and clarify their values; and (3) participate in activities stressing development of critical reading and expository writing skills and use and interpretation of illustrations, graphs, and charts. Each booklet is published with Spanish and English on facing pages. A "student edition" (not included here) and the "teacher's edition" are identical, except for occasional marginal notes in the latter. This booklet looks at social change and how it affects institutions in society. Case study topics include: the growing pains of a small but rapidly expanding Southwestern town; a Los Angeles family forced out of its home by an urban renewal project; and a young couple's debate with parents over changing sex roles. A glossary and a resource list are included. (MSE)
