The basic objectives of the ABC Project, conducted at Tolleson Elementary School during the 1968-69 school year, were to give all disadvantaged migrant children the opportunity to develop a positive self image, build basic language communication patterns, and learn about their present environment in a natural and intellectually stimulating environment. The project attacked 4 areas of concern for migrant Mexican American children: (1) each child was provided a balanced lunch each day to aid nutritional deficiencies; (2) provisions were made for physical examinations and health care; (3) guidance functions included testing, placement, and referral; and (4) an integrated instruction program was provided in experiencing, listening, speaking, reading and writing, and the social skills that underlie these activities. Students were grouped by age and reading levels into 4 groups. The evaluation indicated that there were significant differences in communication patterns and concept formations. (DK)
