起始年龄、语言学能、动机、语言使用与中国英语学习者语法学习成效关系的结构方程模型研究

A SEM Analysis on the Relationship among Age of Onset, Language Aptitude, Motivation and Language Use on Chinese EFL Learners’ Grammar Attainment

二语学习的年龄效应是二语习得领域的一个重要研究问题。大量的研究和学习经历都表明儿童的二语学习比青少年或成人更为优越,但是目前国内外学术界还没有对年龄效应的本质达成共识。本文运用结构方程模型,综合探讨作为认知机制的语言学能以及社会心理因素(动机和语言使用)与我国英语学习者语法学习成效的关系,以期发现各因素对于二语语法学习成效的效应结构,从而为我国的英语教育实践提供参考。

Age of onset (AO) in second language learning has been one of the major topics in SLA studies. Many empirical studies and learning experiences have indicated that children have advantages over teenagers or adults in L2 attainment, but researchers have not reached an agreement on the nature of age effect. This study is intended to explore the relationship among language aptitude, motivation, language use and grammar attainment of Chinese EFL learners by using the PLS-SEM. We hope to establish the effect structure of factors which influence the grammar attainment and provide some plausible suggestions for English teaching and learning in Chinese context.
