This study addresses the question of whether multicultural online supplements can reduce ethnocentricity in students. The results based on data collected through an established "global-mindedness" questionnaire in both a traditional International Business course and one with an online addition, suggest that online supplements are a valuable tool to reduce levels of ethnocentricity and increase international competence. The students in the class with an online supplement showed reduced ethnocentric attitudes, and increase in multicultural awareness and global-mindedness compared with those in the class without the online supplement. Based on these findings, multicultural hybrid course structures can aid in educating the next generation of graduates to perform successfully in a global setting. (Contains 7 tables.)
