"Teachers and students play games quite as much as lovers, diplomats, husbands, and wives. Teachers come to class equipped with 'Threat' cards and students with 'Mischief' and 'Defiance' cards." Exercises in this book can help people, including teachers, students, administrators, and community groups, to overcome their reliance on "game-playing". These exercises, called psycho-social learning experiences, are group activities which generate feelings that are then shared with the group in discussion. One of the authors describes his experience in teaching a course which focused as much on group dynamics as on subject matter. Another author tells about some exercises he used to open up communication in a workshop for teachers. Exercises are listed which focus on the major problems encountered in groups: conflict, problem-solving, leadership, self-concept, and transfer. A glossary of terms and a bibliography, with each selection illustrated by a game presented in it, round out the book. The authors write in the personal, open style they recommend for the reader. (JK)
