Exploring the connectedness of listening tasks according to grades in High School English textbooks

The purpose of this study is to examine the connectedness of listening task difficulty in three Korean High School English textbooks. To achieve the purpose, a corpus which consists of 262 unicode text files was built. The tool for analysis was Coh-Metrix, an automated web-based software tool which was designed to measure and evaluate the coherence of texts. Coh-Metrix was applied to investigate differences among the textbooks according to each grade and differences among the units of each textbook. The measured value of each text was compared and classified into the surface linguistic features (the basic count and readability) and the deep linguistic features (co-referential cohesion, lexical diversity, semantic cohesion, and syntactic complexity). The findings were as follows: First, there was no significant difference among the textbooks according to grades. The case of the 1st grade textbook and 2nd grade textbook in B was the only exception. Therefore, we can't say that there is some connectedness among the textbooks according to grades. Second, there was no systematic connectedness among the chapters in all English textbooks. All these results suggest that more systematic and objective criteria should be applied to the development of English textbooks.
