The Fomative Process of the School-subjects in the Post World War II -On the Case of Arithmetical and Mathematical Courses-

作为小学科目之一的算术课程（Sansuka）是在第二次世界大战后新制定的。1947年3月20日出版的学习课程中规定了这一科目。但内容的主题清楚地表明，在研究过程中的算术和数学课程，发表于1947年5月15日。因此，算术课程的形成似乎与研究课程的形成是统一的。日本和美国官员的会议记录都保存在国立国会图书馆GHQ/SCAP文件中的这一研究课程的会议报告中。通过将其划分为以下三个时期，理清了学科形成的全貌;（1）1946年6月至10月，（2）1946年10月至12月，（3）1947年1月至3月。并对"课程“和”课程“这两个词的含义的形成过程进行了梳理。

The arithmetic course (Sansuka) that is one of the elementary school subjects was newly made after the World War II.This subject was specified in the course of study that was published in March 20, 1947. But the contents of the subject were shown clearly in the course of study of the arithmetical and mathematical courses that was published in May 15, 1947. Therefore, the formation of arithmetic course seems to be united with the formation of the course of study.The minutes of the official both on the Japanese side and the American side are kept in the conference reports of this course of study in the GHQ/SCAP Document that are possessed in the National Diet Library. I cleared the Whole figure of the course of study formation by dividing it into the following three periods ; (1) from June to October in 1946, (2) from October to December in 1946, (3) from January to March in 1947.Also, I made a re-consideration about the formation of the stop-gap textbooks that were used in 1946, and I cleared the formative process about the meaning of the two words 'course of study' and 'curriculum'.
