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 flatter. The three case studies in this booklet focus on values clarification and decision-making, and students take part in the final decision made in each. Case study situations include two different contexts in which young people must make decisions with different degrees of importance, a youth facing problems with conflicting solutions, and a problem demanding an immediate solution. A glossary and a recommended reading list are included. (MSE)
