THE RESULTS OF THE FIRST PHASE OF THE STUDY INDICATED THAT THE CLUSTER CONCEPT WAS AN ACCEPTABLE FORM OF VOCATIONAL EDUCATION AT THE SECONDARY SCHOOL LEVEL, AND PROVIDED A SERIES OF COURSE OUTLINES FOR THE OCCUPATIONAL CLUSTERS OF CONSTRUCTION, METAL FORMING AND FABRICATION, AND ELECTRO-MECHANICAL INSTALLATION AND REPAIR. THE SECOND PHASE AIMED TO DEVELOP TEACHERS CAPABLE OF IMPLEMENTING PILOT CLUSTER CONCEPT PROGRAMS AND A TEACHER PREPARATION CURRICULUM FOR SUCH PROGRAMS. ELEVEN TEACHERS WERE SELECTED ON THE BASIS OF STAFF EVALUATION TO PARTICIPATE IN THE PROGRAM. DURING THE SPRING SEMESTER, IN 16 SESSIONS, THEY DEVELOPED INSTRUCTIONAL PLANS FOR IMPLEMENTING THE PROGRAMS, REVIEWED AND EVALUATED INSTRUCTIONAL MATERIALS, AND ARRANGED THE CONTENT OF EACH CLUSTER INTO AN INSTRUCTIONAL SEQUENCE. DURING A 6-WEEK SUMMER WORKSHOP, THEY WORKED WITH INDUSTRIES TO DEVELOP THE TECHNICAL SKILLS AND KNOWLEDGE REQUIRED FOR IMPLEMENTING THE PROGRAMS AND PREPARED OCCUPATIONAL INFORMATION UNITS AND DEVELOPED INSTRUCTIONAL MATERIALS FOR EACH CLUSTER. AS AN OUTGROWTH OF EXPERIENCES AND OBSERVATIONS OF THE WORKSHOP SESSIONS, TEACHER PREPARATION CURRICULUM WAS DEVELOPED. MAJOR DIVISIONS WERE PROFESSIONAL COMPETENCY DEVELOPMENT FOR CLUSTER CONCEPT PROGRAMS, ORGANIZATION AND ADMINISTRATION, TECHNICAL COMPETENCY DEVELOPMENT, AND INSTRUCTIONAL MATERIALS DEVELOPMENT. EACH DIVISION CONSISTED OF UNITS CONTAINING PURPOSE, TIME, TOPICS, PROCEDURES AND ACTIVITES, AND RESOURCES. THE CURRICULUM IS INCLUDED. THREE OTHER VOLUMES (VT 004 163, VT 004 164, VT 004 165) PRESENT THE INSTRUCTIONAL PLANS FOR EACH OF THE OCCUPATIONAL CLUSTERS. (MM)
