An instructor's manual on choosing a career is provided in this set of prevocational education materials which focuses on the world of work. Objectives include writing in information required on an occupational listing form concerning jobs in the community, developing a tentative occupational plan, and writing in information concerning an area vocational center. (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 eight periods), activity goals, five instructional objectives, related vocational clusters, and activity implementation (description, materials needed, teacher preparation prior to class, during the class, follow-up activities, masters for duplication [e.g., occupational listing form, tentative occupational plan], and a set of transparencies).
