A project was undertaken to develop and disseminate an activity-based learning experience booklet to enhance student self-development in career orientation classes at the junior high school level. Included among the major project activities were the following: identification of an appropriate needs assessment instrument; administration of a needs assessment survey to 447 students in 25 Arkansas junior high schools to determine their perceived career educational needs; development of a set of self-developmental activities for inclusion in a series of three workbooks dealing with life planning, values, and decision making; a review of the workbooks; and implementation of day-long training sessions for 21 Arkansas career orientation teachers. After necessary revisions were completed on the workbooks, 400 copies of them were disseminated to career orientation teachers throughout Arkansas. A comparison of the results of pretests and posttests designed to measure students' self-development and career educational needs supported the effectiveness of the project-developed materials in teaching self-development concepts in grades 7, 8, and 9.
