EQS在应用语言学中的应用——基于英语学习策略、学习观念和自我效能相关性的例证

The Application of EQS in Applied Linguistics——The Case of the Relationships Among Learning Strategies, Learning Belief and Self-effect

EQS是结构方程模型（SEM）的应用软件之一，它能同时分析多变量之间错综复杂的关系，处理非正态分布和缺失值，具有多重拟合指标。近年来，EQS在应用语言学领域应用较少。文章简要归纳了国内外应用语言学中运用EQS的情况，并介绍了EQS的基本操作原理及建模步骤，此外，运用EQS对中学生学习策略、学习观念及自我效能相关性这一实例进行了建模研究，以期为应用语言学和外语教学的研究提供一些借鉴作用。

EQS, one of application softwares for the Structural Equation Modeling, can be used to analyze the complex relationships among multi-variables at the same time, and solve non-normal distribution and missing values with multi-fit indexes. Although EQS hasn't been widely used in applied linguistics in recent years, this article briefly reviews the literature in this area, and introduces the basic theory and operational steps of EQS; moreover, it illustrates the detailed steps of modeling the relationships among learning strategy, learning belief and self-effect by using EQS, so as to provide implications for applied linguistics and English teaching research.
