This is the fourth in a series of reports comprising a nationwide review of the Teacher Corps program; it assesses the program at the University of Southern California and participating schools in Los Angeles and Riverside counties. The program focused on the special educational needs of Mexican-American and black children living in the Los Angeles metropolitan area. Corps members worked with individuals or small groups of children who had language difficulties, disciplinary problems, or were slow learners. Some regular teachers adopted corps members' techniques but others believed that the innovations were not of particular benefit. Corps members were instrumental in the development and operation of learning centers which provided elementary school children with materials for developing their knowledge of mathematics, science, and social studies, and which continued operating after the end of the program. Members also organized or participated in community activities. Eighty-two percent of the interns continued in teaching, most in areas serving low-income families. The university developed two teacher preparation programs modeled in some respects on the Teacher Corps program. The General Accounting Office believes the effectiveness of the programs could be increased by the wider dissemination of information on successful experiments and teaching techniques.
