Jung, Hye Rim Major in English Education Graduate School of Education Sungshin Women's University

This study is a corpus-based analysis of authenticity of vocabulary used in English textbooks of 2007 Educational Curriculum Revision. The purpose of the study is to examine whether vocabulary used in English textbook is authentic or not. For the study, the texts of four kinds of English textbook by Gwan, O-liang of Kumsung(KS), Kim, Sung-gon of Doosan(DS), Kim Duk-gi of Chunjae(Ch-K), and Lee, Jaeyoung of Chunjae(Ch-L) which are from Middle school to High school were used to compile four corpora. Then, four word lists were made through AntConc 3.2.1w. To achieve the purpose of the study, first, basic word list that is suggested by 2007 Educational Curriculum Revision was compared with BNC(British National Corpus) 100 word list. Second, four word lists of English textbooks were investigated how much they included the basic words of 2007 curriculum. Third, each word list of four English textbooks consist of the most frequent 100 words was compared with BNC 100 word list. In addition, each word list of four English textbooks consist of the most frequent 500 words and 1000 words separately was also compared with BNC 500 and 1000 word list. The results of this study are summarized as follows. First, the basic word list of 2007 curriculum had most of 100 BNC word list except three or five words. This indicates that the basic word list consist of authentic words. Second, the reflection rate of basic words of 2007 curriculum which were used in English textbooks was high except a textbook by DS. Except this textbook, the average rate was about 83%. Third, KS excluded 25 words of BNC 100 word list, DS excluded 26 words of BNC 100 word list, Ch-K excluded 28 words of BNC 100 word list, and Ch-L didn't have 32 words of BNC 100 word list. Moreover, the word lists of four English textbooks didn't include BNC words fully in 500 and 1000 word list. Considering the result of the first which showed that the basic word list included most of BNC 100 word list and the second that indicated the reflection rate of basic words of 2007, these textbooks except DS should have had more words of BNC 100 word list in their 100 word lists. Also, this result means that three textbook used authentic words, but they didn't use those words frequently. Based on the finding above, this study proposes two points. First, DS needs to reflect the basic words of 2007 curriculum in the textbook. Second, English textbooks need to increase not only the use of authentic words but also the frequency of the use in textbooks.
