This manual presents a course designed for persons who have direct contact with youth, on an individual or group basis, in a service capacity. The intent of the course is to train youth workers to develop a basic framework for understanding adolescent development, acquire intervention and decision-making skills, and facilitate the growth of adolescents, focusing on basic concepts in order to increase understanding of adolescents, personal perspectives on youth, and individual self-awareness. The materials, presented in modular format, address the following areas of concern: (1) themes of adolescence, (2) labeling and stereotyping of adolescents, (3) personal attitudes toward youth, (4) decision-making skills, and (5) personal learning plans and assessment records. A resource manual of articles dealing with adolescence and a bibliography are also provided. (Author/HLM)
