中国英语学习者书面语水平发展个案动态研究

A dynamic case study on the development of Chinese EFL learners’ written language proficiency

本研究以某大学四名非英语专业学生为受试,依据动态系统理论,对他们英语书面语语言准确性、流利性、词汇复杂性和语法复杂性四个方面的变化进行了48周的跟踪研究。结果表明:经过48周的学习,学生在语言准确性、流利性、词汇复杂性和语法复杂性四个方面的变化轨迹呈非线性,存在波峰和波谷、进步和后滑,书面语语言发展具有明显的动态性和变异性。学生个体的发展趋势与群体变化的发展轨迹并不相同。群体数据反映出的变化是较缓慢的过程,但不同个体会在不同时期出现突变。有些表面相同的变化下有着不同的原因,其中包括生活经历、语言输入、写作时间以及情感因素等。

Based on Dynamic Systems Theory,this study,which lasts for 48 weeks,explores the development of four non-English majorslinguistic accuracy,fluency,lexical complexity and grammatical complexity in English writing.Results show that the changing trajectories of studentslinguistic accuracy,fluency,lexical complexity and grammatical complexity in English writing are non-linear,with peaks and troughs,progress and backsliding.The development of their written English is obviously dynamic and variable.The developmental path for each individual learner differs from that of the group,which shows a slower process.As for different individuals,however,they have great changes at different times.Different factors,including social life experiences,language input,writing time and affective factors,lead to the seemingly same changes.
