不同课程水平英语学习者词汇复杂性研究

The Effects of School Type and Writing Proficiency on EFL Learners' Lexical Complexity Across Course Program Levels

本研究依据课程水平调查学校类型和作文水平对英语学习者词汇复杂性的影响。词汇复杂性分为表层和深层两个维度。多元方差分析发现,不论在何种课程水平中,学校类型和作文水平在词汇复杂性层面均没有交互作用。它们在同一课程水平中不同时发挥作用,且只影响表层词汇复杂性,对深层词汇复杂性没有影响。词汇复杂性不同层面的发展存在竞争关系和补偿效应。

This article investigates the effects of school type and writing proficiency on EFL learners' lexical complexity across course program levels.Lexical complexity is categorized into surface and deep types.The former is measured by lexical sophistication and lexical diversity,whereas the latter by semantic co-referentiality and hyponymy.As multivariate ANOVAs indicate,there is no interaction between school type and writing proficiency on lexical complexity regardless of course program level,and they do not influence lexical complexity simultaneously within each course program level.They exert their effects on surface lexical complexity,but not on deep lexical complexity.Besides,competing relationships and compensatory effects are found to exist between surface and deep lexical complexity.
