At first, the author discussed the utilization of Audio-Visual method to the science teaching on a standpoint of the communication theory, then that the recognition of students (as a receiver) consists of three steps, such as physical reflection, animal reaction and human reflection, and compaired these to the 1st and 2nd signals of Pavlov's reaction. Next, the author considered the education of scientific consideration on a standpoint of scientific recognition, there are many steps of methods for teaching the scientific consideration. On each step, we make concept and this concept goes to higher concept with the progress of steps, then we make the net of concepts in our brains. To make these concepts, we needs various kinds of Audio-Visual methods and there are steps in these methods such as sensitivity, understanding and reason. Then the author discussed the each Audio-Visual aid for the science teaching, at first for the model that represents roughly actual existence, then went to the photograph, the slide, the silent cinema, the tape-recording, the radio, the talkie and the television by turns, these series of Audio-Visual aids changes with the growth of artificial technology, at first separate a little from the actual existence and go on, then at last come back again near the actual existence with the growth of the artificial technology. These specialities are very useful for the science teaching and I suppose that the reasons of this artificial technology as the science teaching, are very important and must be studied in future. At last, the auther discussed the Audio-Visual method, not only as a teaching aid, but also as an action of students, and concluded the necessity of the utilization of the Audio-Visual method for the science teaching theoretically.

The reform of the educational system in U.S.S.R. was carried out in accordance with the thesis of H.C. Хрущев's speech in Central Executive Committie and Cabinet Council of CCCP in 1958,. "On the Intensification of the Connection between School and Actual Life and the Further Development of the Public Educational System." Some of the most important points in the reform of the educational system are as follows; 1.One more year is added to the 7 year course of study in the lower secondary school (ВосЬмилетнеи школе) (compulsory education). 2.All students must learn the study of production (производственное обучение) in the upper secondary school (среднеи шкопес производственное обучение)It may be said that the производственноеобучение is a professional education. So labour in a factory or a collective farm and learning of its fundamental science are carried on simultaneously. And on this occasion, it gives rise to the apprehension that the systematic learning of the fundamental course of study may be disturbed. Besides it is feared that the reform shows a tendency that the studencls specialize themselves at an early stage in their education. Those facts infringe Lenin's interpretation of poly-tecnical education (политехничсекоеобучение) in his note. To conquer these difficulties and to intensify the connection between labour and learning, a proper dealing must be taken in the concreate curricurum, as has been discussed among many pedagogists of U.S.S.R .For this purpose the fundamental knowledge which is useful to all industries, must be taught in the lower secondary school. So it is desirable to complete all course of studies in the lower secondary school. On the other hand, the fundamental study of science must be closely connected with the study of production which students take part in. So the scientific principles of the production must be contained in the process of systematic learning of the fundamental subjects which have relation to the production. From these points of view the author examined the coures of study that had been perfomed in the country, and found many defects in it. He investigated how in the course of study newly established the old defects were corrected, and reported the results. Briefly speaking the corrections are fairly adequate but not fully realized.

The author said the various experimental equipments for physics and chemistry, I will set the main point, not only on the result of these things, but also the attitude of the teachers who are always making efforts for the improvement of the fixed teaching for their science experiments. Actually, I made these students used these equipments for experiments and gainded the good results.
