This book recounts experiments with small groups of social workers and teachers who came together in order to improve their understanding of human relations and personality development. The technique employed can be called non-directive tutoring, and is a type of group-centered discussion. The role of the leader is to clarify and interpret what is happening in the group rather than to direct its content. An account is given of how the group process starts and develops and how the members move toward deeper personal involvement. The changes in the group culture are illustrated by reports of group sessions, including members' personal statements of their experiences. It is shown that such groups provide a form of learning which enables their members to gain a better understanding of themselves and their relations to other people. The group work, though for normal people, is found to have a therapeutic aspect and the type of insight into human behavior so gained is a special feature of this method. (There is a bibliography and a list of books in the International Library of Sociology and Social Reconstruction.) (author/pt)
