This study investigates differences in the writing performance of L1-Korean learners of English as a foreign language (EFL) in response to tasks requiring different genres of writing. Utilizing data controlled for L1 and proficiency level from the Gachon Learner Corpus, the study partially replicates a study by Yoon and Polio (2017), and examines genre effects by comparing descriptive and argumentative essays. A total of 481 essays (270 descriptive and 211 argumentative) from two proficiency groups were analyzed in order to evaluate the effects of different genres on EFL learners' writing performance. Using syntactic complexity and lexical complexity measures, the analysis found statistically significant differences between the two genres. The L2 learners produced more subordination, more of particular structures, and more sophisticated vocabulary in argumentative writing than in descriptive writing. These findings of genre effects can be interpreted on the basis of either the cognition hypothesis or the role of genres' communicative function. No proficiency differences were detected between the two genres except in lexical diversity. The study's findings suggest that existing corpora may be useful for studies seeking to confirm or extend experimental research.

使用语料库分析扩展实验研究:L2 写作中的体裁效应

本研究调查了英语作为外语 (EFL) 的 L1 韩语学习者在应对需要不同写作体裁的任务时的写作表现差异。该研究利用来自 Gachon 学习者语料库的 L1 和熟练程度控制数据,部分复制了 Yoon 和 Polio(2017 年)的研究,并通过比较描述性和议论性文章来检查体裁效应。分析了来自两个能力组的 481 篇文章(270 篇描述性文章和 211 篇议论文),以评估不同体裁对 EFL 学习者写作表现的影响。使用句法复杂性和词汇复杂性度量,分析发现两种类型之间存在统计学上的显着差异。L2 学习者产生了更多的从属关系,更多的特殊结构,议论文中的词汇比描述性写作更复杂。这些体裁效应的发现可以根据认知假设或体裁的交际功能的作用来解释。除了词汇多样性外,在这两种流派之间没有检测到熟练程度差异。该研究的结果表明,现有的语料库可能对寻求确认或扩展实验研究的研究有用。
