고등학교 영어 교과서 읽기 자료의 코퍼스 언어학적 비교 분석

The purpose of this study was to examine and compare the linguistic features of Korean high school English textbooks to explore similarities and differences of the textbooks developed for the revised national curriculum. For this study, we created a corpus of the reading text materials from seven textbooks and analyzed it using Coh-Metrix, a comprehensive computer tool with a rich set of linguistic measures. The results showed that the ba ic counts, word frequency, readability, syntactic complexity, lexical diversity, semantic cohesion, and coreferential cohesion measures of the reading materials varied greatly across textbooks, indicating the lack of specific guidelines and an evaluating tool to control linguistic feature of text materials. Given these results, implications were drawn regarding the benefit of a corpus-based tool for more effective textbook development.
