本研究以复杂动态系统理论为基础，采用质性个案研究方法对东北某高校五名英语专业维吾尔族大学生的英语学习能动性进行了调查。通过对反思日志、自绘轨迹图和半结构化访谈数据的分析，发现维吾尔族大学生英语学习能动性发展具有非线性、个性化和时空情境性特征，发展轨迹既有交汇又有偏离，存在明显的个体差异。能动性发展是个体和外部环境因素之间互动的结果。本研究对高校少数民族英语教学及少数民族地区基础教育有一定启示。

Based on the Complex Dynamic Systems theory, this qualitative case study investigated the English learning agency of five Uyghur students majoring in English at a university in Northeast China. Through the analysis of reflective journals, self-plotted graphs and semi-structured interviews, the study found that the development of Uyghur university students’ English learning agency was characterized as non-linear, personal and spatially temporally situated. The developmental trajectories were both converged and deviated and there were distinct individual differences among the five students. In addition, the development of agency was the result of the interaction between individual and external environmental factors. These findings have implications for minority students’ English teaching at universities and basic education in minority areas.
