Krashen二语习得理论框架下的商务英语写作教学探索

A Study on the Teaching of the Course of Business English Writing within the Theoretical Framework of Krashen's Second Language Acquisition Theory

Krashen的二语习得理论认为只有获得可理解输入且情感过滤足够低,输入才进入语言习得机制,二语习得即得以发生。基于Krashen的"输入假说"和"情感过滤假说"理论框架,从材料任务的真实性、小组合作学习、教师角色的转变、多模态教学手段、课后任务的设置等方面探讨在商务英语写作教学中如何通过输入可理解的材料和降低情感过滤,以提高商务英语写作教学效果。

According to Krashen’s second language acquisition theory, people acquire second lan-guage only if they obtain comprehensible input and if their affective filters are low enough to allow the in-put “in”. When the filter is “down” and appropriate comprehensible input is presented, the acquisition is inevitable. Based on theoretical framework of Krashen’s Input Hypothesis and the Affective Filter Hypoth-esis, the thesis studies how to improve the teaching effect of business English course by selecting the ap-propriate comprehensible material and lowing the affective filters in business English course designing and teaching.
