Research on modern Japanese education , from the viewpointo of nationwide private school

本研究是对日本“BIG3”预科学校(私立高考学校)在全国范围内推广的历史考察。直到20世纪50年代，预科学校还只提供课程。比赛不是由他们自己的工作人员进行的。他们购买了教科书出版商出售的现成考试。没有关于信息的战略。20世纪60年代以后，一些预科学校意识到了信息控制的重要性。在所有这些案例中，位于名古屋的Kawajuku是在东京的高中和分支机构之间铺设管道的先驱，这是在自己的领土之外。最终，它们开始成为对高中和规模较小的预科学校产生影响的“全国性预科学校”之一。

This research is a historical survey about nationwide expantion of Kawaijuku,that is one of the "BIG3" Japanese preparatory schools(private schools for students preparing for university entrance examinations).Until 1950s', preparatory schools provided lessons only. Competitions were not made by their own staffs. They bought ready-made tests sold by textbook publishers. There were no strategy about information. After 1960s', some preparatory schools found the importance of information control. Among all those cases, Kawaijuku, that was located in Nagoya, was the pioneer to make pipelines between highschools and built branches in Tokyo, that was out of own territory. In the end, they started to be one of the "nationwide preparatory schools", that make impact for highschools and smaller preparatory schools.
