| Research Abstract |
The present study aimed to develop a readability index with a powerful explanatory power and a computer program for estimating readability of English texts of Japanese EFL textbooks. In developing Ozasa-Fukui Year Level index, Ver. 2.1, non-linear analyses were computed using a linear function Diff (Diff=0.0995*Words/S+0.4302*Syllables/W+0.9800*WordDiff/W+0.0633*IdiomDiff/S+0.2815) as independent variable and three experts' readability evaluation of 916 sentences as a dependent variable. The computation yielded a non-liner function expression which proved to be much more powerful in predictive power or explanatory power (r^2) than the other currently used linear functions. NewDiff=4.6579*exp (-17.7116*0.3716^Diff)+1 (r^2=.8217) [Diff=0.0995*Words/S+0.4302*Syllables/W+0.9800*WordDiff/W+0.0633*IdiomDiff/S+0.2815]. A computer program was also developed for computing readability using this index.
