A product of a research project designed to improve the teaching effectiveness of vocational teachers of disadvantaged students, this handbook includes the specific procedures and materials that can be utilized in an inservice program for vocational teachers of disadvantaged youth. (The final report of this project is contained in a separate document.) The program is divided into six instructional sessions with each session encompassing two areas of study: Aggressive behavior, classroom interaction, withdrawal behavior, classroom management, supporting behavior, teacher language, reciprocating behavior, instructional concepts, closing behavior, group processes, theory, and role playing. The handbook contains all the informational notes, directions, and practice exercises necessary for each session. The facilitator's guide is also included in the handbook and contains directions, teaching aids, worksheet and transcript answers, and source of materials information for each of the six sessions. The units are designed so that, with minor procedural modifications, they can be studied and completed either during a scheduled inservice meeting or by an individual at home. (BM)
