The guide was designed to assist secondary school classroom teachers in developing and implementing units on cultural diversity. The activities stress the impact of diversity globally as well as in Latin America and can be used as models for examining diversity in other geographic areas. Diversity refers to the heterogeneity of cultures and social structures. The document is presented in four chapters. Chapter I discusses the role of diversity in cultural studies, examines the influence of diversity on global issues, lists objectives, explains the unit format, and provides information on teaching techniques. Chapter II focuses on diversity in the geographic and cultural setting of Latin America. Topics deal with student perceptions about Latin America and attitudes toward cultural diversity. Chapter III examines the relationship of diversity to four global themes--communication, interdependence, conflict, and change. Topics include language barriers, international trade, international relations, and change in urban and rural areas. Activities involve students in class discussion, data analysis, attitude surveys, map and newspaper work, formulation of hypotheses, reading and writing assignments, educational games, role-playing exercises, and completion of 17 handout assignments. For each activity, information is presented on background, objectives, grade level, time and materials required, procedures, follow-up, and evaluation. The final section provides information on evaluating student learning as a result of participating in the unit. (Author/DB)
