THE EFFECTIVENESS OF TELEVISION TEACHING WAS INVESTIGATED UNDER VARIED CONDITIONS OF SCHOOL ORGANIZATION SUCH AS URBAN-RURAL, SEGREGATED SCHOOLS, AND HOMOGENEOUS GROUPING. ADDITIONAL OBJECTIVES OF THE PROJECT WERE TO (1) INTRODUCE TEACHING BY OPEN-CIRCUIT TELEVISION AMONG INDEPENDENT SCHOOL DISTRICTS IN THE HOUSTON AREA, (2) DEVELOP PRACTICAL WORKING RELATIONSHIPS BETWEEN THE TELEVISION STATION OF THE UNIVERSITY OF HOUSTON (KUHT) AND THE PUBLIC SCHOOL SYSTEMS, (3) INVESTIGATE TEAM TEACHING AND IMPROVEMENT OF TEAM TEACHING, AND (4) IMPROVE THE QUALITY OF INSTRUCTION OF HIGH SCHOOL PHYSICS. THE SUBJECT OF HIGH SCHOOL PHYSICS WAS CHOSEN BECAUSE OF ITS POTENTIAL FOR DEMONSTRATION TEACHING AND BECAUSE OF CURRICULUM NEEDS. THE TEST RESULTS INDICATED THAT TELEVISION-TAUGHT HIGH SCHOOL CLASSES ACHIEVED EQUALLY AS WELL AS THE TRADITIONALLY TAUGHT CONTROL CLASSES. THERE WAS ALSO EVIDENCE THAT HOMOGENEOUS CLASSES WERE MORE EFFECTIVE THAN HETEROGENEOUS CLASSES WITH TELEVISION TEACHING. IN ADDITION, THE RURAL HIGH SCHOOL CLASSES AND THE NEGRO HIGH SCHOOL CLASSES MADE SATISFACTORY GAINS WITH TELEVISION TEACHING. INCLUDED IN THE REPORT WERE DISCUSSIONS OF THE ADMINISTRATION OF TELEVISED INSTRUCTION IN RELATION TO INDEPENDENT SCHOOL DISTRICTS, AND THE ROLE OF THE TEAM TEACHER AND HIS CLASSROOM TECHNIQUE. (GD)
