Estimation of English Proficiency by Measuring Three Dimensions of Vocabulary Knowledge: Vocabulary Size, Organization, and Lexical Access Speed

这项研究旨在开发一套多维词汇知识测试，测量网络英语词汇的大小、组织和词汇通达三个维度，其结果可以用来评估考生的整体英语水平。共有392名参与者参加了测试，并提交了他们的托业成绩。结构方程模型的分析表明，当词汇大小和深度构成一个结构时，结构方程模型最适合，词汇测试分数可以预测55%的托业成绩。

This study aimed at developing a battery of multidimensional vocabulary knowledge tests that measure three dimensions of English vocabulary on the web: size, organization, and lexical access and whose results can be used to estimate test-takers'overall English proficiency. A total of 392 participants took the tests and submitted their TOEIC scores. An analysis of Structural Equation Modelling shows that it best fits when vocabulary size and depth constitute one construct and vocabulary test scores can predict 55% of test-takers' TOEIC scores.
