THE OBJECTIVE OF THIS STUDY WAS TO IDENTIFY THOSE FACTORS WHICH FACILITATE OR HINDER THE EFFECTIVE TRAINING OF JOURNEYMAN ELECTRICIANS AND TO EVALUATE THE EFFECTIVENESS OF NEW TEACHING AIDS IN TRAINING THEM, IN HOLDING THEIR INTEREST IN VOLUNTARY TRAINING PROGRAMS, AND IN LEADING THEM TO ENROLL IN FUTURE TRAINING COURSES. ALL JOURNEYMAN ELECTRICIANS WHO WERE MEMBERS OF LOCAL 617, INTERNATIONAL BROTHERHOOD OF ELECTRICAL WORKERS, IN SAN MATEO COUNTY, CALIFORNIA, WERE SURVEYED BY MAILED QUESTIONNAIRES TO DETERMINE THEIR ATTITUDES TOWARD TRAINING AND THEIR TRAINING NEEDS. THE EXPERIMENTAL DESIGN CONSISTED OF TEACHING THE COURSE "INTRODUCTION TO INDUSTRIAL ELECTRONICS" TO A GROUP OF 96 JOURNEYMEN INSIDE WIREMEN BY THREE MODES OF INSTRUCTION. THE INSTRUCTIONAL MODES WERE (1) SELF-PACED INDIVIDUALIZED INSTRUCTION USING A BRANCHING TYPE ELECTRICALLY OPERATED TEACHING MACHINE WITH A HIGHLY QUALIFIED JOURNEYMAN ELECTRICIAN WHO HAD NO PREVIOUS TEACHING EXPERIENCE AS A MONITOR, (2) SELF-PACED INDIVIDUALIZED INSTRUCTION WITH AN OPPORTUNITY TO DISCUSS PREVIOUS MATERIAL AND OUTSIDE READINGS WITH AN EXPERIENCED INSTRUCTOR, AND (3) THE CONVENTIONAL CLASSROOM ARRANGEMENT. EACH MODE WAS MADE UP OF TWO CLASSES WHICH MET FOR 3 HOURS ONCE A WEEK FOR 9 WEEKS. THE MODES WERE DESIGNED TO FOLLOW THE SAME SEQUENCE OF INSTRUCTIONAL INFORMATION TO CONTRAST INSTRUCTIONAL PROCEDURES, NOT CONTENT. PRE- AND POST-ACHIEVEMENT TESTS WERE USED TO MEASURE THE DEGREE OF LEARNING. SOME CONCLUSIONS BASED ON DATA ANALYSIS WERE (1) AUTO-INSTRUCTION WORKED AS WELL AS CONVENTIONAL INSTRUCTION, (2) AUTO-INSTRUCTION WITH LIVE INSTRUCTION YIELDED HIGHER STUDENT SATISFACTION, AND (3) THE UNIQUE PROBLEMS OF ADULT EDUCATION REQUIRE INSTRUCTORS FAMILIAR WITH AND CAPABLE OF TEACHING ADULTS. "TECHNOLOGICAL CHANGE AND THE JOURNEYMAN ELECTRICIAN--AN EXPERIMENTAL STUDY IN CONTINUING EDUCATION, VOLUME II," (VT 002 912) PRESENTS INSTRUCTIONAL METHODS USED IN THE PROJECT. (HC)
