Abstract

This study investigates the extent to which second language (L2) graduate students’ collocation use in academic writing improves with the independent use of a corpus tool, by analyzing the writing assignments of 115 Chinese EFL graduate students from an academic English course. The experimental group (N = 73) received brief in-class training on the use of a corpus tool developed for collocation use (Linggle) and was required to use it for their two homework assignments, whereas the control group (N = 42) was not made aware of the tool before their homework submission. The mean mutual information (MI) scores of the collocations used in the two writing assignments were compared between the experimental and control groups to evaluate the effect of independent corpus consultation (ICC). Overall, the results showed a marginally higher mean MI score for the experimental group, and the differences varied by collocation type. Survey results further revealed that fewer than 40% of the participants frequently used the tool, and the participants reported difficulties in using the query syntax, understanding corpus results, and maintaining technical access to the tool. Our findings have useful pedagogical implications for considering independent corpus consultation as a supplementary tool for academic English instruction.

针对第二语言研究生在学术写作中使用搭配的独立语料库咨询

本研究通过分析学术英语课程中115名中国EFL研究生的写作作业，探讨第二语言（L2）研究生在独立使用语料库工具后，学术写作中搭配使用的改善程度。实验组（73 人）在课堂上接受了关于如何使用针对搭配使用开发的语料库工具（Linggle）的简短培训，并被要求在两次家庭作业中使用该工具，而对照组（42 人）在提交家庭作业之前并不了解该工具。实验组和对照组比较了两次写作作业中使用的搭配的平均互信息（MI）得分，以评估独立语料库咨询（ICC）的效果。总体而言，结果显示实验组的平均互信息得分略高，且差异因搭配类型而异。调查结果显示，只有不到 40% 的参与者经常使用该工具，而且参与者表示在使用查询语法、理解语料库结果和保持对该工具的技术访问方面存在困难。我们的研究结果对于将独立语料库咨询作为学术英语教学的辅助工具具有有益的教学意义。
