The present study investigates how the Japanese Language teaching policy changed during the time of Colonial Korea in 1910s and 1920s from the view point of language education. I found the answer in YAMAGUCHI Kiichiroʼs and ASHIDA EnosukeʼsʻTheories of Teachingʼpolicies. Two scholars who also edited The Japanese textbook.

The main materials used for the analysis of this study are“Japanese Language textbook in elementary school in 1912”(hereinafter referred to as“Yamaguchi edition textbook(1912)”)and“Japanese Language textbook in elementary school in 1923”(hereinafter referred to as“Ashida edition textbook(1923)”). Analyzing the five aspects of Language learning,that is:Listening,Speaking,Reading,writing and Spelling in both the first and second Education Low of Chosun,I discovered that Yamaguchi and Ashida textbooks are important to the development of Language proficiency in Japanese teaching.

As a result,the Japanese Language Education changed their focused from“The Japanese Language teaching policy as a foreign language”,to “The Japanese Language teaching policy as a national language”. Meaning that, they changed the Japanese Language Education their focus from the Spoken Language for language development in the 1910s,to focus on written language in Reading and Writing Education in 1920ʼs. Hence,I believe that the main difference between the Japanese language teaching policy as a foreign language and Japanese Language teaching policy as a national language, lies in the different perspective between that Yamaguchi and Ashida had, between the spoken language and the written language.
