説明

The writer studied the Audio-Visual Education from the standpoint of Information Theory: first, the reaction of primary school pupils at the time of televiewing was searched by utilyzing program analyser or paper-analyser method, and the values of their Y. N. reaction were got. Then the results were plotted on the trilinear co-ordinates. The above research shows that these results are useful in deciding whether before-and-after guidance for TV programs in televiewing is necessary or not. These results, however, are different according to classes or the content of different programs. It is also shown that when the value of M-reaction (between the values of Y and N reaction) begins to decline after having risen to maximum, in most of the cases, the value of Y-reaction rises, while the value of N-reaction rarely rises. This fact being considered from the standpoint of Information Theory, the value of entropy for information was calculated: from this result it is understood that when the value rises to maximum, the eagerness for learning of the children is highest. Then the value decends, while the value of Y-reaction rises: this phenomena can be explained that the effect of learning has risen, and that the integrated value of entropy by the axis of time may have a meaning as the mass of learning. In this treatise as shown in the above, the writer searched for the value of the Y-N reaction of the pupils at the time of their televiewing. Then utilizing trilinear co-ordinate and the value of entropy in the information theory, the writer considered the result to be one of the methods in deciding the necessity of before-and-after-guidance for TV programs, and in considering the eagerness for learning and the effect of learning of the pupils. Hereafter further examinations concerning the results as these will be done with various examples.
