任务复杂度与写作方式对二语写作中学习机会和语言产出的影响

发布时间：2023-05-04 01:18

　　自从Robinson提出了认知假设,许多研究证实了任务复杂度在个人或两个人任务中的影响。但是,这些研究大多侧重口语任务,而且很少研究探究任务复杂度在合作写作中对互动和学习结果的影响。为了弥补前人研究的不足,本论文基于Robinson的认知假设和合作学习的理论,研究任务复杂度和写作方式对学习机会和语言产出的影响。具体有以下研究问题:(1)任务复杂度分别对个人写作和两人合作写作任务中的学习机会和语言产出有什么影响?(2)在不同任务复杂度的条件下,二语学习者在个人写作和两人合作写作中学习机会和语言产出的表现有什么影响?(3)任务复杂度和写作方式对学习机会和语言产出有没有交互影响?为了回答这三个研究问题,本研究采用两个不同任务复杂度的叙述任务,简单任务是有故事结构的任务,而复杂任务没有故事结构。两种写作方式分别是个人写作和两人合作写作。来自广东外语外贸大学的51名中等水平的一年级英语专业学生参加了本实验,其中,17名学生被随机分到个人组,另外34名学生分至两人组,共17对。个人组学习者独自完成简单任务和复杂任务,在完成写作任务的同时进行有声思维。两人合作组则是两人合作共同完成简单任务和复杂任务...
