Comprised of 27 classrooms from grade levels 1-6, the program was primarily designed to provide bilingual education for pupils with limited English speaking ability. However, due to parental requests, almost 16% monolingual English-speakers were accepted into the program. Of the 717 pupils participating in the program 84.6% were Mexican American. Goals for the Mexican American pupils were to: prevent their educational retardation by instructing them in Spanish while developing their command of English; enhance their understanding and cognitive development in both languages; give them the advantage of becoming literate in both languages; and instill a knowledge of and pride in their bicultural heritage. Goals for the other pupils were to: develop understanding and respect for both cultures; develop oral communication skills in both languages; and develop reading and written communication skills in both languages. This report discusses the test results from the: Psychomotor Skills Learned and Demonstrated--Mexican games, songs, and dances; Boehm Test of Basic Concepts; Prueba de Lectura (Spanish Reading Test); Projected Self-Concept Inventory; and Comprehensive Test of Basic Skills. Both English and Spanish versions of these tests were administered on a pre- and posttest basis. Comparisons of the achievement test results for grades 1-5 are included. (NQ)
