One of six staff development training manuals for career guidance infusion in the elementary school curriculum (K-6), this manual focuses on responsible assertiveness training. It is divided into the following six major sections: (1) a list of the major goals and activities covered in the manual; (2) an overview chart displaying the goals, concepts, time, process, and instructional mode of each activity; (3) specific directions for each activity, including objectives, preparation requirements, and materials/equipment requirements; (4) leader's summaries presenting the background information needed to lead the activities; (5) participant worksheets and handouts; and (6) participant summaries. (See CE 018 130 for the final report of this project.) The material covered by this manual includes basic assumptions and techniques of assertiveness training for both teachers and children and the uses of imagery and relaxation training as tools in assertiveness training. In addition to the other five staff development training manuals (CE 018 139-143), a career guidance methods guide for grades K-6 (CE 018 137) is available. (BM)
