本文以某综合性大学在校本科生为调查对象，通过问卷调查收集数据（N＝291），构建结构方程模型，探讨高校学生使用Web 2.0技术辅助外语学习意向的影响因素。研究结果表明使用意向受感知有用性、感知易用性、感知愉悦和便利条件的直接影响；其中感知有用性和感知易用性在研究模型中具有重要的中介效应。该模型能够解释使用意向75.5％的方差变异，表明该模型对促进高校学生使用Web 2.0技术辅助外语学习行为有指导意义。

Computer assisted language learning has been an increasingly important method to improve university students’ language learning experience. To investigate the factors influencing university students using Web 2.0 applications in foreign language learning, this study proposed a research model on the basis of technology acceptance model. Data were collected from undergraduate students (N = 291) at a university through questionnaire. Subsequent structural equation modeling analysis revealed that perceive usefulness, perceived ease of use, perceived enjoyment and facilitating conditions exerted significant direct positive influence upon behavioral intention. Overall, the proposed model accounted for 75.5% of the variance of behavioral intention.
