基于动态系统理论的第二语言发展生态观

The Ecological Perspective of Second Language Development Based on DST

目前二语习得研究大多注重研究变量之间的线性因果关系,强调用量化的方法进行数据分析而忽视语言发展的动态变异。动态系统理论在方法论上摒弃了传统的语言研究方法,指出第二语言发展是一个复杂的生态系统,该生态系统具有自组织性、变异性和异质性的特点。从变异性和多因子交互的角度审视语言生态系统的稳定和变异关系,能够探寻出第二语言发展的路径,为第二语言发展变化提供科学的解释。

Most of the current studies on second language acquisition focus on the linear causal relationship between different variables and emphasize the quantitative methods to process data,thus neglecting the dynamic variability of the language acquisition.The Dynamic Systems Theory(DST)has abandoned the traditional research methodology,pointing out that the second language development is a complex ecosystem,which has the characteristics of self-organization,variability and heterogeneity.The examination of stability and variation of the language ecosystem from the perspective of variability and multi-factor interaction can help investigate the trajectories of second language development and provide a scientific explanation for the development and changes of the second language.
