The author discusses the use of role-play to teach research ethics in three semesters of a research methods class. Small groups of students were assigned one of nine ethical norms discussed in the course textbook and the American Sociological Association Code of Ethics. Each group role-played the violation of their assigned ethic to the class. The class guessed the ethical norm that was being violated. Written, open-ended feedback from students demonstrates overwhelming approval and appreciation for this activity. Role-playing the violation of ethical norms is appropriate for a course in any discipline that includes a discussion of research ethics. (Contains 2 tables.)
