This manual provides curriculum materials for implementing a career exploration class in transportation occupations within a Practical Arts Education program for middle/junior high school students. Introductory materials include the program master sequence, a list of transportation occupations (land, water and aerospace transportation families), an overview of the competency-based instructional system for practical arts, and a narration for a slide-tape presentation. The instructor's guide to learning activities contains guide sheets for each task assignment sheet; these guide sheets present objectives, attitudes and values to be developed, one or more checkout activities, recommended references and audiovisuals, notes and suggestions for instruction, and references and necessary tools and equipment. Master copies of learning activities are included. Appendixes include lists of vocabulary, practical arts videotapes, references appropriate for career exploration, and ideas for addressing students with special needs. The 12 student task assignment sheets are also included. Each contains these components: an introduction, objectives, learning activities, checkout activities, vocabulary, instruction sheets, and a copy of the instructor's final checklist. The tasks focus primarily on auto mechanics and include such activities as disassembling, repairing, reassembling and maintaining two- and four-cycle engines. (YLB)
