【摘要】：近年来,可读性公式由于在测试文本难度时简单易用和操作性高的特点受到了广泛的关注。然而其信度和效度却受到了很大的争议。尤其在EFL领域,是否可以利用可读性公式来测试文本难度成为很大的争议。但是以往大多数研究都只是对可读性公式进行简单,片面的利用研究,没有对多种可读性公式进行综合,全面的研究。本文综合应用了六种可读性公式,通过Main Divergence和Index Means对可读性公式结果的综合分析探讨了可读性公式在测试EFL文本难度的可行性,旨在回答以下问题： (1)对EFL课本阅读材料的可读性指数进行综合分析能否得出与在课本中的难度指数相符合的结果? (2)可读性指数综合分析得出的结果在不同语言水平的表现是否一致? (3)四个不同可读性公式在测试文本难度得出的结果是否一致?如果不一致,哪个公式表现最好,哪个最差? 本文测试了四个语言水平的20篇EFL文本的难度。文本难度是通过对六个可读性公式结果的综合分析得出,对可读性指数进行了Main Divergence和Index Means分析。结果显示通过可读性公式综合分析得出的文本难度与其在课本中的文本难度有一定偏差。六个可读性公式在测试难度水平最低和最高文本最能达到一致,而在难度中等的文本中分歧较大。我们可以得出可读性公式在EFL领域的综合应用只能给我们一个大概的难度分类,对单个文本很难提供准确,有效的测试结果。
[Abstract]:In recent years, readability formulas have attracted wide attention due to their ease of use and high maneuverability in testing text. However, its reliability and validity have been greatly disputed. Especially in the field of EFL, it is controversial whether the readability formula can be used to test the text. However, most of the previous studies are only simple, one-sided use of the readability formula, there is no comprehensive and comprehensive study of the various readability formulas. In this paper, six kinds of readability formulas are synthetically applied, and the feasibility of the readability formula in testing the difficulty of EFL text is discussed through the comprehensive analysis of the results of main divergence and Index means. The purpose of this paper is to answer the following questions: (1) can a comprehensive analysis of the readability index of EFL textbooks produce a result consistent with the difficulty index in the textbook? (2) the results of the comprehensive analysis of the readability index are in different languages. Is Ping's performance consistent? (3) are the results of the four different readability formulas consistent in terms of the difficulty of testing the text? If not, which formula performs best and which is the worst? this paper tests the difficulty of 20 EFL texts at four language levels. The difficulty of the text is obtained by synthetically analyzing the results of the six readability formulas, and the main divergence and Index means are used to analyze the readability index. The results show that there is a deviation between the difficulty of the text and the difficulty of the text in the textbook by comprehensive analysis of the readability formula. The six readability formulas are the most consistent in the lowest and the highest text level, but diverge in the middle difficulty text. We can conclude that the comprehensive application of readability formula in EFL can only give us a rough classification of difficulty, and it is difficult to provide accurate and effective test results for a single text.
