尽管词汇教学中越来越多地使用“文本覆盖率”来衡量阅读材料的可理解性，但迄今为止，很少有研究涉及影响可靠的文本覆盖率计算的方法论变量。本文的目的是调查不同的词汇量、文本长度和样本量如何影响文本覆盖率的稳定性，并确定相关的参数。本研究以英国国家语料库中的23个不同大小的高频词和时间年鉴语料库中的26个不同长度的文本为样本，在1000次迭代中使用10种不同的样本量来计算文本覆盖率，并用平均得分和标准差的分布对结果进行了分析。研究结果表明，词汇量越大，语篇长度越长，使用的样本越多，语篇覆盖率越稳定。研究还发现，较短样本数目较大的文本覆盖率的稳定性比较少较长样本数目的文本覆盖率稳定性更大。作为教育工作者的实用指南，在计算文本覆盖率时，包括了一个显示最小参数的表格，以供参考。
Although the use of "text coverage" to measure the intelligibility of reading materials is increasing in the field of vocabulary teaching and learning, to date there have been few studies which address the methodological variables that can affect reliable text coverage calculations. The objective of this paper is to investigate how differing vocabulary size, text length, and sample size might affect the stability of text coverage, and to define relevant parameters. In this study, 23 varying vocabulary sizes taken from the high frequency words of the British National Corpus and 26 different text lengths taken from the Time Almanac corpus were analyzed using 10 different sample sizes in 1,000 iterations to calculate text coverage, and the results were analyzed using the distribution of the mean score and standard deviation. The results of the study empirically demonstrate that text coverage is more stable when the vocabulary size is larger, the text length is longer, and more samples are used. It was also found that the stability of text coverage is greater from a larger number of shorter samples than from a fewer number of longer samples. As a practical guideline for educators, a table showing minimum parameters is included for reference in computing text coverage calculations.
