An institute to retrain teachers (K-8) for multicultural education was evaluated to determine 1) types of knowledge relevant to teaching in a minority community that can successfully be taught in an 8-week summer institute and 2) changes in attitude and conceptual structure associated with the institute. The program included sensitivity training sessions, role playing activities, and educational seminars. Participants were certified teachers with at least one year of experience in the district (Ravenswood, California); they were employed for the succeeding year to complete the inservice curriculum-development part of the project. Instruments developed for use in evaluation were a 28-item attitude inventory to measure attitude toward racial and ethnic groups; two 20-item word association scales to assess attitude toward concepts given emphasis in the training; and a 150-item final examination covering the six instructional units: Black Experience in Literature, Racism and Prejudice, History of the Civil Rights Movement, History of Tropical Africa in the 19th Century, Afro-American History, and Contemporary Education of Afro-Americans. Instruments were administered as pre- and posttests to participants (N=25) and as posttests to a control group (N=20). Although findings indicated more success in correcting misinformation and imparting new knowledge than in changing attitudes, the institute was considered successful.
