【摘要】：本文主要基于如何预测初中英语教科书文本可读性的问题展开讨论。在国内外文本可读性研究成果的基础上,借鉴前人研究思路、研究方法对我国初中英语教科书文本可读性进行研究,试图为教学者与学习者选择适宜水平的学习材料提供简便的衡量方法。本文在文献综述的基础上得出了一个包含句子、词汇两个大维度,词长、句长七个小维度的英语文本可读性影响因素分析框架。鉴于该分析框架基于国外的已有研究,不能直接应用于我国初中英语教科书文本可读性的分析。本文在已有研究总结出的分析维度的基础上,编制了针对初中英语教科书文本可读性影响因素的调查问卷,通过对四所初中学校不同年级的120名学生进行了调查,最终得出包括两个大维度、九个小维度,共计20种影响因素在内的初中英语教科书文本可读性影响因素分析框架;基于该影响因素分析框架,本文对从人教版与外研版两个比较有代表性版本的英语教科书中选取的61个样本进行了文本分析,并得出了各个影响因素的适度区域值;接下来,在前面研究的基础上,本文通过相关性分析以及多元回归分析的方法建立起了一个可以预测初中英语教科书文本可读性年级水平的简易公式:Y=7.590+0.620X1—0.118X2+0.029X3—0.098X4,其中,Y为文本的年级水平;X1为每百词连词数;X2为每百词主题词数;X3为每百词五级词汇数;X4为每百词简单句数。该公式有较好的拟合度,能够解释71.4%的变异,但该公式的有效性仍需要进一步的实践检验。最后,笔者对整个研究过程进行了理性思考,对本研究中存在的不足进行了总结,并指出了未来的研究方向。
[Abstract]:This paper mainly discusses how to predict the readability of middle school English textbooks. On the basis of the research results of readability of English texts at home and abroad, this paper studies the readability of English textbooks in junior high schools in our country by referring to the previous research ideas and methods. This paper attempts to provide a simple measurement method for teachers and learners to choose appropriate level of learning materials. On the basis of literature review, this paper presents an analytical framework for the readability of English texts, which includes two dimensions of sentence, two large dimensions of vocabulary, seven small dimensions of word length and sentence length. Since the analysis framework is based on existing research abroad, it can not be directly applied to the readability analysis of junior high school English textbooks in China. On the basis of the analysis dimension summarized by the previous studies, this paper compiled a questionnaire to investigate the factors affecting the readability of English textbooks in junior high school, and investigated 120 students of different grades in four junior high schools. Finally, an analysis framework for the readability of junior high school English textbooks is drawn, which includes two large dimensions, nine small dimensions and a total of 20 influencing factors, which is based on the analysis framework of the influencing factors. This paper analyzes the text of 61 samples selected from two representative versions of English textbooks, one is the educational version and the other is the extrapolated edition, and the appropriate regional value of each factor is obtained. Then, on the basis of the previous research, the paper makes a textual analysis of the text of the 61 samples selected from the two representative versions of the English textbook. By means of correlation analysis and multivariate regression analysis, this paper establishes a simple formula for predicting the readability of junior high school English textbooks: yang7.590 0.620X1-0.118X2 0.029X3-0.098X4, where Y is the grade level X1 of the text. X2 is the number of thematic words per hundred words, X3 is the number of five levels of vocabulary per hundred words, and X4 is the number of simple sentences per hundred words. The formula has a good fitting degree and can explain 71.4% variation, but the validity of the formula still needs to be tested in practice. Finally, the author makes a rational thinking on the whole research process, summarizes the shortcomings of this research, and points out the research direction in the future.
