An instructor's manual and student activity guide on basic electricity are provided in this set of prevocational education materials which focuses on the vocational area of trade and industry. (This set of materials is one of ninety-two prevocational education sets arranged around a cluster of seven vocational offerings: agriculture, home economics, distributive education, health occupations, world of work, trade and industry, and office occupations.) The instructor's guide is organized into the following elements: title of activity, duration of activity (six to ten classes), activity goals, instructional objectives (seven), related vocational clusters, and activity implementation (description, materials needed, safety considerations, teacher preparation prior to class, during the class, follow-up activities, answer key to student check point activities and masters for duplication [i.e., job supervisor's material list, wiring plans]). The student activity guide, organized for different groups (salespersons, delivery persons, inspectors, job supervisors, and workers), provides step-by-step instructions (narrative and illustrations) for completing each instructional objective. Objectives include identifying electrical symbols and items, stripping and joining wire, and taking material orders. At the end of each set of instructions is a student check point (evaluation activity). An occupational description for an electrician concludes the document. (JH)
