THE 3 MOST OBJECTED-TO FEATURES OF INSTRUCTIONAL TV ARE (1) RESTRICTIONS IMPOSED BY THE USE OF A SPECIAL STUDIO, (2) LOSS OF TEACHER-STUDENT CONTACT, (3) THE LIMITED VIEWING AREA OF TV SCREENS. THIS STUDY INVESTIGATED 4 CLOSED-CIRCUIT TV COURSES IN AN ATTEMPT TO MINIMIZE FEATURES (1) AND (2). OVER THE ACADEMIC YEAR 1957-58 AT THE CASE INSTITUTE, COURSES IN GRAPHICS 1 AND 2, CHEMISTRY, AND ELECTROMAGNETIC FIELD THEORY WERE TAUGHT BY CLOSED-CIRCUIT TV. A 2-WAY VIDEO AUDIO SYSTEM PROVED SUCCESSFUL IN PRESERVING STUDENT-TEACHER CONTACT. IT WAS FOUND THAT CONVENTIONAL CLASSROOMS CAN BE SATISFACTORY TV ORIGINATING POINTS. A LIVE CLASS WAS PRESENT IN THE ORIGINATING ROOM. EQUIPMENT WAS CHOSEN FOR MAXIMUM MOBILITY AND DEPENDABILITY. EQUIPMENT USED AND OPERATING COSTS ARE DISCUSSED. THERE WAS NO CONTROLLED EVALUATION OF STUDENT ACADEMIC ACHIEVEMENT. STUDENT AND INSTRUCTOR ATTITUDES WERE MEASURED BY QUESTIONNAIRE. STUDENTS GENERALLY PREFERRED LIVE INSTRUCTION, WHILE INSTRUCTOR ATTITUDES VARIED. IT WAS CONCLUDED THAT TV IS MOST VALUABLE AS AN INSTRUCTIONAL AID, NOT AS A MEDIUM. TV WAS NOT FOUND SUITABLE FOR TEACHING ABSTRACT MATERIAL. TV SHOULD BE USED AS AN INSTRUCTIONAL MEDIUM ONLY WHEN TEACHING STAFF OR LECTURE FACILITIES ARE NOT ADEQUATE. STUDENTS WERE FAVORABLE TOWARDS TV AS AN AID. FURTHER DETAILS AND SUGGESTIONS ARE GIVEN. (MS)
