This teaching and resource unit on Mexican Americans is designed for advanced level students of Spanish, mainly in the eastern United States, who are of a middle-class, suburban background. One of its chief purposes is to increase the understanding of needs of minority groups so that future voting citizens of the majority culture will be more disposed to change and to finance change. The objectives of the unit are presented along with details on suggested books and materials, method and content with areas of emphasis, organization and activities, and means for evaluation. A sample test and attitudinal survey are included. Supplementary information includes a Chicano glossary, a chronological outline of Mexican history, a listing of members of the Chicano Press Association, a listing of sources of information, an annotated bibliography on Mexican Americans and Mexico, and a list of Mexican American resource persons in the Washington, D.C. area.
