This guide on group discussion leader training provides for a four session course structured to enable each trainee to practice and be evaluated. Session 1 stresses the nature and uses of discussion, and introduces trainees to role playing. Other sessions concentrate on summarizing and decision making; on group satisfaction or problem solving and the relation of discussion leaders to resource persons; and ways of dealing with individual problems. Appendixes provide sample topics for practice sessions, followed by possible variations on sample discussions and training design.
