项目摘要

This research investigated the relationship between vocabulary knowledge measured in three dimensions, size, organization, and recognition speed, and general language proficiency. To measure vocabulary size, J8VST was used, which sampled words from the most frequently used 5,000 words in the JACET 8000 Word List and challenged test-takers to choose the English word among four choices that represents a Japanese word stimulus. To measure vocabulary organization, LOT was used, which challenged test-takers to choose two words among three that form the strongest connection of three possible combinations of the three words. To measure recognition speed, LEXATT was employed. In Part 1 of LEXATT test-takers find a common word hidden in a string of letters and the reaction time is measured. In Part 2 of LEXATT, test-takers try to recognize a word as quickly as possible and choose the meaning of the recognized word. The participants of the study took all three vocabulary test and the TOEIC test … More and the relation among the test results was sought. The regression analysis found that a TOEIC score can be predicted by the scores of the three vocabulary tests but the confidence interval is too large to trust estimated scores. The Structural Equation Modelling analysis adopted a model that best explains TOEIC scores. The model does not include LOT scores because the reliability of the test was very low, .31. The model found a moderate correlation between size and access speed scores, which means that learners with a large vocabulary size have faster access speed. However, access speed did not have any relation with TOEIC reading or listening scores. It was found that only vocabulary size was responsible for TOEIC scores. This may be due to the validity and reliability of the lexical organization test and the lexical access test. Further studies should aim at improving the validity and reliability of these tests. The three tests developed can be accessed at: http://mochvocab.sakura.ne.jp/. Less

本研究考察了词汇知识在大小、组织和识别速度三个维度上的测量与一般语言水平的关系。为了测量词汇量，使用了J8VST，它从JACET 8000单词列表中最常用的5000个单词中抽取单词，并要求测试者从代表日语刺激的四个选项中选择代表日语单词刺激的英语单词。为了测量词汇组织，使用了LOT，要求考生从三个单词中选择两个单词，这两个单词构成了这三个单词的三种可能组合中最强的联系。为了测量识别速度，使用了LEXATT。在LEXATT的第一部分中，考生发现一个隐藏在一串字母中的常见单词，并测量了反应时间。在LEXATT的第二部分中，考生试图尽可能快地识别一个单词，并选择识别单词的意思。这项研究的参与者参加了所有三项词汇测试和托业测试…并对试验结果之间的关系进行了探讨。回归分析发现，托业成绩可以通过三个词汇测试的分数来预测，但可信区间太大，不能信任估计的分数。结构方程模型分析采用了最能解释托业成绩的模型。该模型不包括批次分数，因为测试的可靠性非常低，0.31。该模型发现词汇大小与词汇获取速度得分之间存在中等程度的相关性，这意味着词汇量较大的学习者具有较快的获取速度。然而，通达速度与托业阅读或听力成绩没有任何关系。研究发现，只有词汇量才是托业成绩的决定因素。这可能是由于词汇组织测试和词汇通达测试的效度和可靠性。进一步的研究应该着眼于提高这些测试的效度和可靠性。开发的三项测试可在以下网站上访问：http://mochvocab.sakura.ne.jp/.较少
