"Exploring Careers" is a career education resource program, published in fifteen separate booklets, for junior high school-age students. It provides information about the world of work and offers its readers a way of learning about themselves and relating that information to career choices. The publications aim to build career awareness by means of occupational narratives, evaluative questions, activities, and career games grouped in fourteen occupational clusters. This tenth of the series, "Mechanics and Repairers," presents an overview of jobs in mechanical and repairing occupations, such as watch repairers, business machine repairers, and telephone installers. Narrative accounts focus on an auto mechanic, a computer service technician, and a jeweler, describing what they do and how they prepared for their careers. Exploring sections relate skills needed for these occupations to students' personal characteristics, and learning activities such as making metric conversions and building a small computer from a kit are suggested. A Job Facts section lists nature and places of work, training and qualifications, and other information for twenty-eight mechanical and repairing occupations, grouped into occupational clusters of telephone crafts, and other repairing occupations. ("Exploring Careers" is also available as a single volume of fifteen chapters.) (KC)
