The purpose of this study is to analyze and test the effects of desegregation on the self-concept and attitudes of black secondary students in Pointe Coupee Parish, Louisiana. In particular, the study investigates the extent to which black students attending public schools in America which harbor "de jure segregation" acquire negative self-concepts and negative attitudes toward an understanding of the educative process -- which attitudes could be detrimental to their psychoeducational development. One of the salient findings derived from this study is that black students in predominantly black schools involved in the study exhibit higher self-concepts and more favorable attitudes than black students in predominantly white schools. It is recommended (1) that the study be replicated and expanded to include a large cross sample of all senior high students and (2) that research should also be conducted to compare the changes in self-concepts exhibited by a group of black students only in just one racial composition.
