The purpose of this study is to examine how particular courses that are inclusive of diversity in their content and methods of instruction, what educators will call "diversity courses," promote the importance students place on taking personal responsibility for social issues and problems. Two types of courses are compared in this study: diversity and traditional courses. Data were gathered from students enrolled in two separate diversity courses and an introductory management course. The diversity courses, a social diversity course and a women's studies course, had a combined enrollment approximately equal to the enrollment in the management course. This study makes several important contributions to one's understanding of how diversity courses can influence students' interactions with diverse peers and the importance they place on social action engagement. The results demonstrate that previous enrollment in diversity courses and enrollment in one of the diversity courses in this study (compared to enrollment in a management course) are positive, significant determinants of the quality of students' interactions with diverse peers. As such, diversity courses in general and the particular diversity courses in this study are preparing students for the inherent challenges that await them as they enter an increasingly diverse workforce.
