This booklet on the educational techniques of role playing describes a method designed to help children become decision-makers by providing a life-related way to help them learn to solve problems between people. Part 1 describes the role-playing method in which children act out the ending of an unfinished "problem story" which stops with a dilemma usually demanding a choice between a personal interest and a social value. Part 2 on how to guide a role-playing session focuses on each step in the process: warming up, selection of participants, preparing the audience, role playing, discussing and evaluating, replaying the revised roles, sharing experience and generalizing. Part 3 discusses the planning of a curriculum to provide a program in intergroup education. Part 4, "A Strategy for Intergroup Education," includes six problem stories with discussion of their use in individual group acceptance, intergroup relations, and sensitivity training. Part 5 on involvement contains a problem story focusing on a "busybody or good Samaritan" dilemma. Part 6 describes special uses of role playing, e.g., how it can be used to relieve a disturbing classroom situation and to bring help to a handicapped child. Part 7 illustrates how children can write their own problem stories. Part 8 on role playing for younger children includes discussion of pantomime, dramatic play , and use of problem pictures as a stimulant for role playing. A 53-item bibliography is included. (JS)
