This publication presents two suggested Mexican American studies curriculum units. In total they represent a cross-section of materials that have been developed to deal with the learning problems of students with special language difficulties. Originally developed for grades 7 through 12, these units may be adapted for use in adult education or at any other grade level. The units were developed by the Calexico Intercultural Design and were classroom tested during 1970-75 in the Calexico Unified School in California. The units are entitled "Mexican Immigrants in the United States," and "Imperial Valley," and each unit has an English and a Spanish version. The units include a series of reading passages, a glossary of relevant vocabulary, suggestions for extended activities, and worksheets to accompany the readings. The units are followed by a bibliography, suggestions for teachers using the units, and answer sheets for the worksheets. (CLK)
