I. Problem and Purpose The school broadcast for moral guidance should aim not only to promote the acceptance of the advocated value, but also to let the children grasp the meaning of its content, differing from other persuasive means of communication, such as propaganda and commercial advertisement. The purpose of this experiment is to examine how the four combinations of the two factors-treatment of the content and utilization of the program-will affect each other and to see the most ideal combination for the realization of the best acceptance of advocated value. II. Hypotheses (1) A "self-contained" program which draws the conclusion explicitly is more valuable for the acceptance of its advocated value. However this type of program, accompanied with group discussion, will decrease the acceptance of advocated value. On the other hand, it is expected this type of program interferes with the children being able to consider and draw conclusions by themselves so they do not grasp the real meaning of the content. Also the discussions will not supplement this shortage. (2) An "open-end" program which intends to make an audience consider and draw the conclusion (advocated value) will promote both the acceptance and the understanding with discussions following. Without having discussion it will be inferior to a "self-contained" program on both effect. III. Procedures a. Subjects: 291 (8 classes of) second grade boys and girls of the Forth Musashino Middle High School and the Kitatama Komae Middle High School took part in the experiment. b. Subject groups (1) Discussion Group I - who listened to the "self-contained" program with the classroom discussion after it. (2) Discussion Group II - who listened to the "open-end" program with the discussion after it. (3) Non-discussion Group I - who listened to the "self-contained" program without discussion after it. (4) Non-discussion Group II - who listened to the "open-end" program without discussion after it. c. Procedures (1) Transcribed programs: the original version ("self-contained" program) and the revised version ("open-end" program) of "Akirameyoka" in a series of "Aozorahan Note (Our Group Activities)" presented by NHK. (2) Moral test sheets (3) Sheets for the test after listening to the program Those tests were conducted in April and May, 1964. IV. Conclusions The hypotheses on the acceptance of advocated value for it were all supported. On the other hand, those hypotheses on the understanding of the program content were not clearly proved because the desirable understanding was acquired by only a considerably few. But it was found that in the case of "openend" group with discussions (Discussion Group II) the discussions decreased the "undesirable" understanding and increased the "ambiguous" understanding of the program.
