The Purpose of this research was to analyze how the objectives which the producer had were reflected in the content, construction and representation techniques of the program he made and to evaluate to what extent students could understand it. In order to clarify the objectives of the program adopted in this research a brief interview was held with the producer beforehand. The measurement tools were a pre-test, a post-test (both of them developed by our research members) and a response analyzer. The TV program used in this research was "Living things in the tidepool" which was broadcast on June 5th in 1984. (NHK) The main results were as follows. (1) According to the producer, the most important objective of the program was "understanding of the program as a whole" or "understanding of how living things in the tidepool adapt to their environment. "Analyzing the test results, it was found to be almost achieved. (2) The test scores in relation to factual knowledge were low. But the memorization of facts was not an objective of the program. So this result is not thought to be the evidence of the program's fault. (3) There were two special representation techniques used in the program. They were effective in terms of arousing affective response of the students. (4) There was no difference in the degree of understanding of the program between the two grades (6th-9th). Furthermore, there was little difference between the teachers and the students. This is a desired outcome of the program of this kind. (5) The results of the response analyzer showed that there was a main difference between the cognitive and affective response pattern of the students and the importance response pattern of the teachers. By this, it could be said that the teachers and the students, both receivers of the same program, tend to be differently affected by the program depending on whether the purpose to watch it is the preparation for instruction or the learning of new information. The conclusion is that the program evaluated in this research was effective in terms of the attainment of the producer's objectives.
