THE PURPOSE OF THIS STUDY WAS TO LOCATE CLOSED-CIRCUIT TELEVISION (CCTV) INSTALLATIONS IN EDUCATIONAL INSTITUTIONS ACROSS THE UNITED STATES, COMPILE A DIRECTORY OF THESE INSTITUTIONS, DESCRIBE THE EQUIPMENT AND FACILITIES IN USE, LOCATE PATTERNS OF UTILIZATION OF CCTV SYSTEMS, AND DESCRIBE THE DEVELOPMENTAL PROCESS OF THIS NEW FORM OF EDUCATIONAL INSTRUMENTATION. THE METHODOLOGY INVOLVED LOCATING CCTV INSTALLATIONS IN EDUCATIONAL INSTITUTIONS, PREPARING A QUESTIONNAIRE ENTITLED "CLOSED CIRCUIT TELEVISION DATA FORM," CONDUCTING A COOPERATIVE STUDY TO DETERMINE THE POTENTIAL NUMBER OF SCHOOLS RECEIVING EDUCATIONAL TELEVISION SYSTEMS, VISITING VARIOUS CCTV INSTALLATIONS, AND ATTENDING A NUMBER OF CONFERENCES ON EDUCATIONAL TELEVISION. THE FINDINGS OF THE STUDY WERE SUMMARIZED IN THE AREAS OF FACILITIES AND EQUIPMENT AND UTILIZATION. THESE CCTV SYSTEMS RANGED FROM A SINGLE CAMERA-RECEIVER INSTALLATION TO A STATEWIDE NETWORK, ALTHOUGH MOST SYSTEMS OPERATED WITHIN A SINGLE BUILDING OR INSTITUTION. CCTV HAS DEVELOPED ABOUT TWICE AS RAPIDLY IN INSTITUTIONS OF HIGHER EDUCATION THAN IN INSTITUTIONS OF ELEMENTARY AND SECONDARY EDUCATION. THE NUMBER OF INSTALLATIONS AND INSTITUTIONS HAVING CCTV SYSTEMS INCREASED SHARPLY, THIS WAS LARGELY DUE TO THE NATIONAL DEFENSE EDUCATION ACT OF 1958 (NDEA). CCTV ASSISTED EDUCATORS IN MANY WAYS, ALTHOUGH CCTV WAS USED MAINLY AS A SYSTEM OF COMMUNICATION OR AS AN AUDIOVISUAL TOOL. CCTV FACILITIES WERE AN INTEGRAL PART OF MANY SCHOOLS AND INSTITUTIONS OF HIGHER EDUCATION WHERE THE USE OF INSTRUCTIONAL TECHNOLOGY WAS IN OPERATION.
