限时写作条件下任务前构思和在线构思对二语写作语言表现的影响

The Effects of Pre-task Planning and On-line Planning on L2 Written Linguistic Performance in Timed Writing

本文探讨了任务前构思与在线构思两种不同的构思方式在限时写作条件下对二语写作语言表现的影响。两个二语水平层次的120名中国大学非英语专业学生参与了实验,对他们的文本进行了流利度、准确度、复杂度的统计与分析。结果发现,写作者在任务前构思的条件下写作的流利度有显著提高,准确度、句法复杂度也有提高,但幅度不显著,而词汇复杂度在在线构思的条件下有一定提高,但幅度也不显著。二语水平与不同构思方式对写作的流利度和准确度没有交互影响,对写作的复杂度有交互影响,任务前构思对二语水平高的写作者在句法复杂度和词汇复杂度方面都有促进作用,而对低水平写作者没有帮助。以上结果表明任务前构思与在线构思对二语写作语言表现有不同的作用,这对二语写作教学与测试都有一定的启示。

This article reports the results of a study on the effects of pre-task planning and on-line planning on L2 written linguistic performance in timed writing. 120 Chinese university non-English majors of two different L2 proficiency levels participated in the experiment. Their written texts were coded and analyzed in terms of fluency,accuracy and complexity. Results showed that pre-task planning improved the learners' fluency significantly while a little with accuracy and syntactic complexity. On-line planning helped to improve the learners' lexical complexity,but not to a large extent. There was no interaction between planning style and L2 proficiency affecting fluency and accuracy,but the interaction could be observed in terms of both syntactic complexity and lexical complexity,which indicated that learners of high L2 proficiency benefited from pretask planning in complexity while learners of lowL2 proficiency did not. The findings indicates that pre-task planning and on-line planning have different effects on L2 written linguistic performance,which provides some implications for L2 writing teaching and testing.
