Development of a Vocabulary Test Battery Estimating English Skills and Proficiency : Integrating Vocabulary Size, Organization, and Access Speed

本研究从词汇量、词汇组织和词汇识别速度三个维度考察了词汇知识与总体语言水平之间的关系。为了测量词汇量，使用了J8 VST，它从JACET 8000单词列表中最常用的5,000个单词中抽取单词，并要求考生在代表日语单词刺激的四个选择中选择英语单词。为了测量词汇组织，LOT被使用，它要求考生从三个词中选择两个词，这些词构成了三个词的三种可能组合中最强的联系。为了测量识别速度，采用LEXATT。在LEXATT测试的第一部分中，考生在一串字母中找到一个隐藏的常用单词，并测量反应时间。在LEXATT的第二部分，考生试图尽快识别一个单词，并选择所识别单词的含义。受试者参加了所有三个词汇测试和托业考试 ...更多信息 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次词汇测试的成绩来预测，但置信区间太大，无法相信估计的成绩。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LOT评分，因为测试的可靠性非常低，为0.31。该模型发现，规模和访问速度得分之间的适度相关性，这意味着学习者具有较大的词汇量有更快的访问速度。然而，访问速度与托业阅读或听力成绩没有任何关系。结果发现，只有词汇量的大小是负责托业成绩。这可能与词汇组织测试和词汇通达测试的效度和信度有关。进一步的研究应致力于提高这些测试的效度和信度。所开发的三个测试可在以下网址查阅：http://mochvocab.sakura.ne.jp/。少

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.
