Chung, So-Woo. 2014. A Corpus-based Analysis of the Frequency and Text Coverage of Coxhead (2000)’s Academic Words in Research Articles on English Education. Korean Journal of Linguistics, 39-4, 997-1019. The purpose of this paper is two-fold: 1) to examine whether the vocabulary size of a text or its topic affects the overall text coverage of AWL words, and 2) to analyze the frequency and text coverage of AWL words in research articles on English education written in English by Koreans. Using a concordance program, Antconc, this paper found that the number of AWL words occurring in a text may increase in proportion to its vocabulary size, but the overall AWL text coverage does not. It showed that the text coverage of the AWL words accounted for around 11.83% in 55 research articles on English education written by Koreans and published in Korea, which was a little bit higher than the coverage ratio of 11.49% observed in the data of 33 research articles on teaching English as a foreign language, published in England and the USA. But, it was much higher, by around 2.31%, than the coverage ratio of 9.52% in the data of 20 research articles on teaching English as a mother tongue that were published in the USA. It also revealed that, in research articles on teaching English as a foreign language published in Korea, England and the USA, the AWL text coverage was a little bit higher in the abstract, introduction and conclusion sections than in the methods and results sections. It further identified 45 word families which are not included in West’s General Service List and Coxhead’s AWL, but whose average frequency is higher than that of the word families in those two lists.
