This study investigates whether the effectiveness of educational television programs is influenced by the frequency of text inserts and the amount of information each insert contains.Quasi-experimental design was used for this study. An effective sample of 250 students enro- lled in the National Open University was divided in to seven groups,and a three-by-two experimental design was used.To maxi- mise the reliability and effectiveness of this study,video- taped teaching material was employed and a purpose-specific competency test was used. The finding of this study indicate that the form of presentation used in the television medium influences the presentation of information and has varying effects on educa- tional effectiveness.In an age where distance education is grow- ing in importance,carefully planned research is needed on the form of presentation used in media-based education. This will enhance the effectiveness of broadcasting;zh_TW
