A STUDY ATTEMPTED TO DETERMINE WHETHER HIGH SCHOOL STUDENTS WHO HAVE GAINED KNOWLEDGE AND UNDERSTANDING OF CONCEPTS IN ANTHROPOLOGY WOULD--(1) ACHIEVE GREATER SELF-INSIGHT, (2) BECOME LESS ETHNOCENTRIC IN THEIR ATTITUDES TOWARD OTHERS, AND (3) INCREASE THEIR ABILITY TO THINK CRITICALLY ABOUT SOCIAL PROBLEMS. A 1-YEAR EXPERIMENTAL COURSE ON WORLD CULTURES PRESENTED LEARNING EXPERIENCES USING INTELLECTUAL AND EMOTIONAL STIMULI FOR STUDENTS TO TAKE THE ROLES OR ATTITUDES OF OTHER ADOLESCENTS IN OTHER CULTURES. ONE EXPERIMENTAL AND TWO CONTROL GROUPS OF STUDENTS RECEIVED A BATTERY OF PRE- AND POST-EXPERIMENT TESTS. RESULTS SHOWED THAT THE EXPERIMENTAL GROUP GAINED IN ACHIEVING LESS ETHNOCENTRISM AND THAT OTHER HYPOTHESES WERE NOT PROVEN. OTHER IMPLICATIONS WERE DISCUSSED. (JM)
