THIS PROJECT WAS AN ASSESSMENT OF 74 INSTITUTES OFFERED IN 1965-66, UNDER THE PROVISIONS OF THE NDEA, FOR 3,149 EDUCATIONAL MEDIA SPECIALISTS. THE PROJECT'S MAJOR CONCERNS WERE (1) HOW DOES ATTENDANCE AT AN EDUCATIONAL MEDIA SPECIALIST INSTITUTE CHANGE PARTICIPANTS, (2) IN WHAT WAYS DO THESE INSTITUTES INFLUENCE PROFESSIONAL PROGRAMS FOR THE PREPARATION OF EDUCATIONAL MEDIA PERSONNEL, AND (3) WHAT MAKES A "GOOD" EDUCATIONAL MEDIA SPECIALIST INSTITUTE. DATA WAS GATHERED VIA REPORT FORMS, INTERVIEWS, QUESTIONNAIRES, AND OBJECTIVE TESTS. FINDINGS SHOWED THAT THE INSTITUTES IMPROVED PARTICIPANTS' KNOWLEDGE AND ATTITUDES RELATING TO EDUCATIONAL MEDIA. AS A RESULT OF THE INSTITUTES, PROFESSIONAL PROGRAMS IN EDUCATIONAL MEDIA RECEIVED GREATER ATTENTION AND ENROLLMENT, IMPROVED COURSE CONTENT AND CONTACTS WITHIN THE FIELD, AND USED NEW METHODS. THE "GOOD" INSTITUTE SHOULD BE WELL PLANNED, ADMINISTERED, AND STAFFED, AS WELL AS SELECTIVE, VARIED (IN TYPES OF INSTRUCTION), INNOVATIVE, PROFESSIONAL, AND PRACTICAL. RECOMMENDATIONS ARE MADE FOR FUTURE INSTITUTES OF THIS KIND. (MS)
