AN INSERVICE TEACHER EDUCATION PROJECT UTILIZED CLOSED CIRCUIT TELEVISION AS A MEDIUM OF CLASSROOM OBSERVATION. IT WAS HYPOTHESIZED THAT CLOSED CIRCUIT TELEVISION COULD MAKE STAFF INTERVISITATION MORE EFFECTIVE. CLOSED CIRCUIT TELEVISION WAS USED IN 46 INSERVICE EDUCATION SESSIONS AND 51 SESSIONS WITH OTHER RELATED SCHOOL PURPOSES DURING THE EXPERIMENTAL PERIOD. THE RESEARCH DESIGN WAS ESTABLISHED TO GATHER JUDGMENTS FROM OBSERVERS, TEACHERS, AND TELEVISION PROJECT STAFF. DATA WERE GATHERED BY MEANS OF (1) WRITTEN DESCRIPTIONS AND APPRAISALS BY OBSERVERS AT VIEWING SESSIONS, USING AN OBSERVATION AND EVALUATION SCHEDULE, (2) INTERVIEWS CONDUCTED THROUGHOUT THE DISTRICT WITH PARTICIPATING TEACHERS, USING THE SCHEDULED INTERVIEW PROCEDURE, AND (3) FORMAL EVALUATION DISCUSSIONS WITH THE SUPERVISORY STAFF. THE RESEARCH REPORTED 16 CONCLUSIONS WHICH RANGED FROM EQUIPMENT CONSIDERATIONS TO CRITERIA FOR INSERVICE EDUCATION SESSIONS. (HB)
