IN 1963 THE NEW YORK ACADEMY OF MEDICINE, WITH THE NEW YORK CITY MUNICIPAL BROADCASTING SYSTEM, INAUGURATED AN EXPERIMENTAL PROGRAM OF WEEKLY ONE-HOUR TELEVISED CLINICAL SCIENCE SEMINARS TO EXPLORE THE ACCEPTABILITY AND EFFECTIVENESS OF OPEN-CIRCUIT TELEVISION AS AN ADDITIONAL MEDIUM OF CONTINUING MEDICAL EDUCATION IN A LARGE METROPOLITAN AREA. THIS REPORT PRESENTS FINDINGS OF THREE AUDIENCE SURVEYS CONDUCTED BY THE ACADEMY AND THE BUREAU OF APPLIED SOCIAL RESEARCH OF COLUMBIA UNIVERSITY AND PRESENTS RESULTS OF A SUBSEQUENT STUDY OF THE EFFECTIVENESS OF THE PROGRAM. THERE WAS A STEADILY GROWING AUDIENCE FOR THE WEEKLY BROADCAST, 408 IN PRIVATE PRACTICE ALONE ESTIMATED AS AVERAGE IN JANUARY 1964. THE EFFECTIVENESS IN RAISING INFORMATION LEVELS OF VIEWERS DIFFERED GREATLY FROM PROGRAM TO PROGRAM AND ALSO ACCORDING TO INITIAL EDUCATION-SPECIALIZATION LEVEL. BENEFITS MAY LIE IN REFRESHING KNOWLEDGE, STIMULATING FURTHER SEARCH, SHORING UP EXISTING KNOWLEDGE, AND IMPARTING SENSE OF JUDGMENT. (INCLUDED IN THE DOCUMENT ARE 17 TABLES AND THE TEXT OF TEST QUESTIONS.) THIS ARTICLE APPEARED IN THE BULLETIN OF THE NEW YORK ACADEMY OF MEDICINE, SECOND SERIES, VOLUME 42, NUMBER 8. (RT)
