试论二语图式的建构

图式理论在国内外二语习得研究及教学中得到广泛的重视和应用。人们对新知识的解读和处理取决于大脑中已存在的图式，并且母语已有图式会对二语学习造成干扰和负迁移。但是不断接触新的事物，新的图式也会不断形成。因此，我们应该为二语学习者提供真实、有意义的认知资料，营造良好的语言环境，使他们在环境和社会交际相互作用中积极构建知识。

On Construction of the Schema for Second Language

The schema theory plays an important role in the SLA research and teaching.Intending to bear out its impact on Chinese students in their second language learning,this article holds that although the schema of our mother tongue existing in our brain determines the interpretation and handling of new knowledge and such schema produces interference and negative transfer on the learning of second language,we do not always rely on the same mapping and instead new mappings will form with experience of new exemplars.Therefore,we need to furnish the students with authentic teaching materials and create a communication-oriented situation to help the students voluntarily construct knowledge through interaction with the environment and social negotiation.
