| Research Abstract |
The purpose of this study is to quantitatively analyze the English textbooks of the Meiji, Taisho and early Showa eras (1968-1940). In 2004 one set of the five Books of Girls Pacific Readers (Kairyudo, 1938), authored by Sawamura, was digitalized. The digitalized file was put into the textbook English corpus, which consisted of the digitalized texts of 14 sets of the English textbooks that were used in Japan during the span of 140 years. The textbook corpus was quantitatively analyzed in terms of (1)tokens, (2)types, (3)new types, (4)token/new type ratio, (5)Flesch Reading Ease, (6)Flesch Kincaid Grade Level, (7)passive sentences and (8)nominative relative pronoun. The results of these analyses shed light on some aspects of the development/change of the English textbooks of Japan over the 140 years. In particular, the comparison of the quantitative indices of the 14 sets of the textbooks revealed that the new words and tokens of the textbooks were drastically decreased over the 140 years and that, in contrast, the new type/token ratio was drastically increased. These findings were combined with the findings of the qualitative analysis and a comprehensive interpretation and evaluation was conducted on the process of the development/change of the English textbooks of Japan over the span of 140 years.
The findings of these analyses were published in Ozasa and Erikakwa eds. Historical Study of English Textbooks (2004, Jiyusha, in Japanese). They were also published in seven national and international journals and orally presented in eleven national and international conferences.
