Human relations units are presented in this guide designed for teachers of secondary grades. The aim is to educate students in the philosophy of humanism. Emphasis is upon social interaction in an attempt to help pupils not only realize their own potential, but moreover, to respond to the needs of others. Each of the four activity units deals with factors in human relations and outlines the focus, broad goals, generalizations, instructional objectives, and learning activities. Unit one examines the development of personality in an attempt to help students gain self-understanding by studying the effects of heredity and environment. Focus in unit two is upon students understanding and perceiving themselves and others. Problems and conflicts among individuals and groups is the topic for unit three. Unit four stresses effectiveness of communication. Books, articles, and films are included in a resource list. Appendices provide worksheets, charts, and cartoons. (Author/SJM)
