Abstract
The aims of the present study were (1) to empirically evaluate validity of a newly developed readability index, Ozasa-Fukui, Ver. 2.1, by correlation analyses, and (2) to compare the readability data of fourteen Japanese EFL textbooks measured by the new index and those by Flesch-Kincaid Grade Level. The correlation analyses revealed that Ozasa-Fukui was the most powerful in differentiating the readability of selected 84 EFL sentences. It was also found out that the coefficient between Ozasa's criterion and Flesch- Kincaid was also remarkably high, much higher than that of Flesch Reading Ease. The comparative analyses revealed that Ozasa-Fukui was more powerful in differentiating Book 1 texts, and that Flesch-Kincaid was rather powerful in differentiating the texts of higher years.
