基于Coh-Metrix的艺术类大学英语教材难易度研究

A Coh-Metrix Based Study on the Complexity of English Teaching Materials for Art Universities

摘要: 本研究选取由清华大学出版社出版的2016年12月第1版的第一册与第二册艺术类大学英语综合教程为分析对象，从中提取出60篇阅读文本语料，使用由美国孟菲斯大学研发的网络文本分析工具Coh-Metrix对文本的难易度进行研究。结果表明：艺术类大学英语教材阅读语篇所选取的主题丰富、内容全面。在叙述性、句法简单性、单词具体性、深度衔接以及可读性五个层面基本符合当代大学英语教学的需求，但在篇章阅读难度、生僻词汇以及长难句等方面仍存在很大的改进空间。为此，教材编写应注重基础英语知识教学，合理调整文本难度，从而夯实学生英语水平、优化教学成果。

Abstract: This study selected the first volume and the second volume of the first edition of College English Course for Arts published by Tsinghua University Press in December 2016 as the objects of analysis, extracted 60 reading texts as the corpus, and used Coh-Metrix, a network text analysis tool developed by the University of Memphis in the United States, to study the text complexity. The results show that the topics selected in the reading texts of art college English textbooks are rich and the content is comprehensive. The five aspects of narrative, syntactic simplicity, word concreteness, deep cohesion and readability are basically in line with the needs of contemporary college English teaching, but there is still a lot of room for improvement in reading difficulty, rare vocabulary and long and difficult sentences. Therefore, teaching materials should pay attention to basic English knowledge teaching, reasonable adjustment of text difficulty, so as to consolidate students’ English level and optimize teaching results.
