The main purpose of this study was to analyze the continuity of the reading scripts inthe Korean middle school English 1, 2, 3 textbooks using an automated languageanalysis program, Coh-Metrix. Coh-Metrix is a computer program which can beapplied to evaluate English textbooks based on many linguistic and psycholinguisticmeasures. The Coh-Metrix measures analyzed for this study include basic counts (thenumber of words, the number of sentences, average sentence length), word frequency,standard readability scores (Flesch reading ease score, Flesch-Kincaid grade level),syntactic complexity (subject density, noun density), lexical diversity (type-token ratio),co-reference cohesion, semantic cohesion, pronouns, and connectives. In general, thefindings of this study showed that the continuity among the middle school English 1, 2,3 textbooks was controlled properly for the basic counts and the subject density score.
However, the continuity among the middle school English 1, 2, 3 textbooks was notcontrolled suitably for the other measures. The findings of this study embrace valuableimplications for the development of English textbooks.
