A special Training Institute on Problems of School Desegregation was held at the North Carolina Advancement School; the project was undertaken to determine the degree of attitude change related to group learning method, social attitude set, and characteristics of race, sex, and age among 72 teachers and counselors participating in an adult education program. The program, an institute on problems of school desegregation, provided an intensive educational experience which attempted, during an eight week period, to change cognitive and affective components of attitudes of prejudice among the participants. The study was concerned with the rational-irrational, social distance, and sympathetic identification dimensions of prejudice. Evidence has been presented supporting a fundamental postulate of the study that attitude change is related positively to participation in an intensive adult education experience. Attitudes of the subjects changed in the predicted direction as related to participation in the institute on all dimensions of prejudice included in the study. The findings of this research support and strengthen the postulate as a basis for future research. (se)
