利用Bachman语言能力模型重塑全英文教学的化学课堂

Using Bachman Communicative Language Ability Model to Reconstruct Chemistry Class Instructed in English

针对全英文授课中的一些普遍问题,结合作者近年来在相关化学课程全英文教学的实践和思考,借鉴了Bachman语言能力模型,提出一种全英文化学课堂的设计新方法。课堂上积极主动、丰富的交流和反馈是形成有效教学的关键。鉴于此,全英文课堂中要特别关注五个要素:专业知识、语言知识、策略能力、语言环境和个人特征。因此在课程准备的过程中就需要从这五个方面入手,对教学方法和策略进行重新设计。同时,设计中必须意识到全英文教学中专业知识和英语能力培养的两个维度应该是相互支持和依赖的。实践表明,这一新的教学模式通过活跃课堂气氛、正向激励、及时反馈和促进主动学习显著提高了教学质量和课程满意度。

Aiming at common problems of classes instructed in English,we propose a new design method by referencing the Bachman communicative language ability model,based on the author’s practice and thinking in recent years.Active communication and feedback in class are the keys to effective teaching.In view of this,we should pay special attention to five elements in English-based class:professional knowledge,language knowledge,strategic ability,language environment and personal characteristics.Therefore,we need to redesign the teaching method and strategies from these five aspects.At the same time,teachers must realize that the two dimensions of professional knowledge and language ability should be mutually supportive.Our practice shows that the new mode can significantly improve the teaching quality and curriculum satisfaction by activating the classroom atmosphere,promoting positive motivation,timely feedback and active learning.
