One of five sections of materials for a program to change teacher attitudes toward career education, the leader's guide presents a plan for a three-day teacher inservice workshop involving role playing by both dissonant and consonant groups. The dissonant group consists of persons with low change orientation who assume roles advocating career education. However, the consonant group participants reflect their measured attitudes, either for or against, in the role playing. Included are workshop activities for each day, materials and suggestions for the leader, workshop handouts, a post-workshop evaluation form, and typical career education lesson plans. (Author/MF)
