A COMPREHENSIVE STUDY OF INSTRUCTIONAL MEDIA MANPOWER REQUIREMENTS AND RELATED PROFESSIONAL EDUCATION PROBLEMS WAS CONDUCTED. THE SPECIFIC OBJECTIVES WERE (1) TO ESTABLISH A JOB CLASSIFICATION SYSTEM FOR MEDIA SERVICES, (2) TO SUGGEST DIMENSIONS FOR FUTURE STUDIES OF MANPOWER REQUIREMENTS FOR MEDIA SERVICES, (3) TO SPELL OUT PROCEDURES FOR OTHER SIMILAR STUDIES, AND (4) TO SUGGEST DATA WHICH COULD BE GATHERED TO CONTRIBUTE TOWARD THE DEVELOPMENT OF EDUCATIONAL OBJECTIVES, CURRICULUM, AND TRAINING MATERIALS FOR PERSONS WORKING IN ANY OF THE MEDIA FIELD SPECIALITIES. PROCEDURES INCLUDED COMBINING THE TECHNIQUES OF FUNCTIONAL JOB ANALYSIS AND THE CRITICAL INCIDENT TECHNIQUE TO PROVIDE (1) QUANTITATIVE INDICATORS FOR GROUPING MEDIA JOBS ACCORDING TO AREAS OF PERFORMANCE OR CAPABILITY, INTERESTS, AND SATISFACTIONS AND (2) SOME QUALITATIVE DIMENSIONS FOR CLASSIFYING EDUCATIONAL REQUIREMENTS FOR THE OCCUPATIONAL GROUPS DERIVED. A COMPUTER-BASED MULTIVARIATE STATISTICAL ANALYZER SYSTEM WAS ADOPTED FOR "FINDING" THE RELEVANT OCCUPATIONAL GROUPS AND RELEVANT VARIABLES. THE MULTIDIMENSIONAL PERFORMANCE SPACE OBTAINED PROVIDES A WAY OF VIEWING THE CHANGES TAKING PLACE IN JOBS. FINDINGS REVEALED--(1) AS MORE TECHNOLOGICAL CHANGES OCCUR IN INSTRUCTIONAL SERVICES TO SCHOOLS AND COLLEGES, THE RELATIONSHIP BETWEEN OCCUPATIONS IN DISCRETE WORK FIELDS IS EXPECTED TO DIMINISH, (2) THAT SEVERAL DIFFERENT JOBS EXIST TO ACCOMPLISH THE SAME FUNCTIONAL TASKS, AND (3) A WHOLE NEW RANGE OF JOBS, EACH ASSOCIATED WITH PARTICULAR SKILLS AND KNOWLEDGES HAS BEEN IDENTIFIED -- EDUCATIONAL TECHNICIANS, EDUCATIONAL SPECIALISTS, EDUCATIONAL COMMUNICATIONS SPECIALISTS, AND EDUCATIONAL MANAGERS.
