ABSTRACTThis study expands the literature of online human diversity courses in social work by comparing the effectiveness of these courses to face-to-face instruction. To measure effectiveness, pre- and posttests were completed by 117 students. The instrument used measured awareness of and ability to recognize cultural diversity and oppression and the level of belief that our society is just. The findings suggest that online and face-to-face students showed an increase in their awareness of diversity and oppression issues with little to no significant difference between the two groups. Although not statistically significant, the online students’ belief in a just world decreased, whereas their face-to-face counterparts showed an increase, which was an unexpected finding. Implications for online social work classes are discussed.
