A diversity training initiative at the University of Wisconsin-La Crosse involves social action theater. Participants in the United We Learn Social Action Theatre present brief plays developed on the basis of their experiences or of campus or community events. A diversity issue is presented in the play in a way that creates a conflict among the actors. When the conflict reaches a critical juncture, a moderator halts the action and calls on audience members to ask the actors questions. After the first question-and-answer period, the moderator again stops the action. Eventually, the actors introduce themselves and answer questions from the audience on the basis of their real-life experiences. The play is a vital part of the diversity training, but the moderated audience-actor dialogue facilitates the critical learning experience. Social action theater, if used ethically, is a safe and creative way to improve race relations. Assumptions underlying social action theater, determining the level of campus support, ethical considerations, identification of issues, selection of themes for scenarios, script development process, roles, facilitating discussion, and evaluation are discussed.
