CQPweb在ESP写作教学中的应用研究

Applying CQPweb to an ESP writing course

CQPweb是基于网络的语料库在线检索平台。本研究创建了农科英语论文语料库HZAU CQPweb,用于辅助本科生ESP写作教学。写作教学引进了数据驱动学习方式,对学生进行检索技术培训。在微观层面,学生利用CQPweb检索解决写作中选词、搭配、同义词辨析等问题;在宏观层面,学生通过CQPweb检索归纳写作要点和经典句型、了解不同写作群体的观念态度差异、掌握写作要点的语篇分布及其功能。写作课程结束后的问卷调查结果表明,CQPweb是一种有效的语言学习资源和工具,有利于英语学习者写作质量、写作信心及自主学习能力的提升。调查结果也凸显了语料资源有待丰富、学生不太适应CQPweb的复杂检索模式等问题。

CQPweb is an online corpus query platform. In this study, HZAU CQPweb, an agricultural science corpus of English papers, is created and applied to the teaching and learning of an ESP writing course. CQPweb search techniques are imparted to the students and Data-driven Learning （DDL） is adopted in the writing course. Microscopically, the students are guided to solve such puzzles as diction, collocation, synonym discrimination through corpus search in the course of writing. Macroscopically, the students are exposed to the key moves and useful expressions in writing, the differences in general attitudes held by different writer groups, and the distribution of key moves and their discursive functions. The questionnaire survey following the writing course indicates that as an effective language learning tool and resource, CQPweb improves the students＇ writing quality, confidence, and autonomous learning ability. The survey also reveals that the existing corpus remains to be enriched, and CQPweb search needs to be simplified.
