This Child Development Associate (CDA) training module, the last in a series of 16, focuses on preparing trainees in a competency-based bilingual/bicultural preschool teacher training program to help Mexican American children to develop positive self-concepts. The first four sections of the module text deal with the effects of the following factors on the development of the child's self-concept: (1) interactions with family members in the home, (2) teachers' attitudes and expectations (with emphasis on negative attitudes toward Mexican Americans and Spanish accents), (3) conflicting cultural values (e.g., cooperativeness vs. competitiveness) and (4) attention to arranging the school environment so that it expresses a positive attitude toward the child's culture. The final section of the text suggests techniques and strategies for the selection and presentation of activities which enhance the child's development of a positive self-concept. The module includes trainee learning activities, and a pre-test and a posttest of the trainee's understanding of the material. The module focuses on the specific behaviors which directly relate to CDA Competency 2. (BH)
