| Summary: | This study attempted to provide definitive answers to the question of the effectiveness of television instruction in high school chemistry under varied conditions. The sample obtained included predominantly white and negro schools using television (four of each), and predominantly white and negro schools not using television (six and one). Gross qualitative judgments of the (1) adequacy of laboratory facilities, (2) quality of teachers, and (3) mental ability of students were used as controls. Effectiveness of television teaching was measured by a comparison of student grades on a standardized chemistry test given in both the television and nontelevision schools. While significant differences were noted, the resultant data proved inconclusive, probably because of (1) the inadequacy of the sample size, (2) the inability to obtain adequate controls, and (3) the gross measures used in the variables. It was suggested that in future studies steps should be taken to insure control of the television users so performance differences can be assigned to the specific influence of television or to other factors.
