A graduate course on culture, diversity, and cultural competence was developed based on constructivist learning theory and Campinha-Bacote's constructs of cultural awareness, knowledge, skill, and encounters. The epistemology, structure, assignments, and activities used in both online and classroom courses were highly effective and well received by the students. Student course evaluations and outcome assessments of students' cultural competence levels, as compared to precourse levels, provided supportive evidence that the course design produced intended outcomes. Course resources are shared, making them available for use by others in cultural competence education.
