THE PURPOSE OF THIS PROJECT WAS TO TEST THE EFFECTS OF INVOLVING VOCATIONAL AGRICULTURAL TEACHERS IN THE DEVELOPMENT AND EXPERIMENTAL USE OF INSTRUCTIONAL MATERIALS. A GROUP OF 16 TEACHERS AT A SUMMER WORKSHOP PARTICIPATED IN PLANNING THE CONTENT AND DESIGN FOR 13 OVERHEAD PROJECTION MASTERS AND MADE PLANS FOR USING THEM EXPERIMENTALLY. THE TEACHERS ALSO AGREED TO EXAMINE THEIR INSTRUCTION PROGRAMS AND TO SEND THE PROJECT DIRECTOR SUGGESTIONS ON CONTENT FOR OTHER USEFUL PROJECTION MASTERS. AT THE TIME OF REPORTING, THE MATERIALS WERE BEING USED BY 14 OF THE 16 TEACHERS. SEVEN SIGNIFIED A DESIRE TO ATTEND ANOTHER INSTRUCTIONAL MATERIALS DEVELOPMENT WORKSHOP. REPRODUCTIONS OF THE PROJECTION MASTERS WERE INCLUDED. THIS VOLUME REPRESENTS PART 11 OF THE 13-PART FINAL REPORT ON THE VOCATIONAL-TECHNICAL EDUCATION RESEARCH AND DEVELOPMENT PROJECT OF WASHINGTON STATE UNIVERSITY.
