Abstract
This article was intended to clarify the logic of cooperation of youth school (seinen gakko) and training of skilled worker historically. I use the concept of cooperation in the meaning of a way to solve dual-issue between school and enterprise. I needed four research tasks for historical clarification of the cooperation theory. In other words, it was factor and contents of dual-issue, reform movement for a way to solve the issue and reason of setback. Through these analyses, the following things became clear. The factor of dual-issue was caused compulsory youth school (post advanced elementary education) for boys and obligation of training of skilled worker. The contents of dual-issue were complicated and multifaceted issue that occurred from nation, enterprise, workshop, institution of education and training, student (training worker). The reform movement for a way to solve the issue was proposed by "Nihon kogyo kyokai (The Japan Association of Industry)" and "Shigemi Kirihara". The logic of both was based on "unification" and "full-scale training" and "graded selection training method". However, "unification" was not adopted by the proposed amendment of the Ministry and Welfare. The reform movement was at a standstill for reinforcement of the war regime by wartime exception. Finally, as results of research, I can point out the characteristic of cooperation. Firstly, the logic of cooperation had been included five types. Secondly, the muting process of the logic is possible to divide the logic into three periods according to their special features. Thirdly, the logic came to the conclusion for the recurrence to dual supervision theory of education and training. In this way, these three points became clear; therefore we can understand the logic and muting process of cooperation. The argument of cooperation provided many useful suggestions in regarding relationship of education and industry.
