Japan's educational television and radio network, NHK, conducted surveys and studies on the use and effects of its programs from 1960-68. The major surveys, each of which is summarized in this booklet, cover four categories: the utilization of educational programs, analysis and evaluation of selected programs, the effect of educational programs, and the effect of non-educational broadcasting (entertainment and adult programs) on children. The first category includes surveys on the utilization of school broadcasts by schools, on school teachers' views of educational broadcasting, and on the daily life of high school students taking correspondence courses and their utilization of broadcasts. The second group of studies analyzed a fourth-grade science class and a junior high school English class and also included a study on the function of audiovisual methods in concept formation. Studies in the third category looked at the effects of television programs in teaching English, in teaching moral guidance, and on children in isolated villages. Included in the fourth category are studies on the effects of violent scenes on children and on ways of changing children's choice of programs. (JK)
