复杂理论:二语习得研究的新视角

Complexity Theory:A New Perspective in SLA

二语习得/发展可以被看成异质的、动态变化的、非线性的、自适应的、开放的复杂系统,系统中各要素交互作用引起了二语习得发展的变化。"复杂理论"就是对系统中各要素的变化、要素间交互作用的变化、系统轨迹的变化及系统与其它系统的关系进行描述、解释和预测。在复杂理论的新视角下,二语习得领域中值得探索的方向包括语法中的"怪现象"、二语能力的测试、二语习得系统的建模、二语发展轨迹的个体内差异研究、方法论研究等。

Second language acquisition or development can be observed as a heterogeneous, dynamic, non-linear, adaptive and open complex system, in which the interaction between various elements causes the change. ＂Complexity Theory＂ describes,explains and predicts the changes of elements, the changes of interaction, the variability in trajectory and the relationship between systems. Under the new perspective of complexity theory, there emerge some feasible and meaningful topics to be explored, including ＂weird grammar＂, the measurement of second language level, the simulation of second language acquisition system, the intra-individual differences in second language development trajectory and methodology researches.
