A teaching technique called guided design is used in this exercise to help college students enrolled in introductory world history courses learn about the Nazi persecution of the Jews. Providing a change of pace to traditional lectures, readings, exams, and papers in history courses, guided design, as used in this activity, confronts students with the documentation of past Nazi events and leads them to productive discussions involving the moral and practical decisions demanded by those events. Included are teacher instructions and student materials. Intended for use during a single 50-minute period, the exercise requires no prior announcement, no special reading, and no library assignment. Previous exposure to general textbook accounts and lecture material on totalitarianism, World War II, and Nazi generals is helpful. At the beginning of the class, students are divided into three or four person decision groups. Prepared materials are distributed, and the ground rules of the guided design are explained. Student groups are presented with questions which they must discuss, and then reach a group consensus. Each group presents its consensus to the class as a whole. (RM)
