语境再现线索导向对二语读后续写协同效应的影响

Effects of Cue-Induced Contextual Recurrence on Alignment of the Continuation Task

读后续写为开放性写作,不同学习者的续作往往差别较大,无法确保其协同强度和促学效果最大化。本研究设计可再现前文语境的线索导向,以加强续写内容与前读材料之间的联系,旨在解决上述问题。在本研究中,两组英语学习者分别对同一材料的甲、乙两个版本进行读后续写。甲版本在结束处植入可再现前文语境的线索导向,乙版本则无该导向。结果发现,该线索导向:(1)显著增加了读后续写的续作长度;(2)显著提升了被试对前文词语和词块的采用率;(3)显著减少了冠词偏误,但却催生了更多的中式英语,对主谓一致、冠词、系动词、不定式、时态等方面的偏误则无显著影响。研究结果表明,线索导向可增强读后续写的协同效应,从而弥补读后续写的促学短板。

The continuation task faces a general problem,i.e.,it fails to ensure strong alignment and thus high efficiency in promoting L2 learning because learners’ continuations usually vary substantially.The present study intends to address the problem by designing a cue to induce recurrence of the preceding context in the task to bind the continuations and the reading text closely.Two groups of L2 English learners were invited to partake in the task with and without such a cue respectively.It is found that the cue significantly increased the length of L2 learners’ writings,enhanced their adoption of the words and lexical chunks in the reading material and had a different impact on the number of errors they made.The findings indicate that the cue can strengthen alignment of the task and thereby make up for its shortcoming.
