Learner Corpus Writing Ability Assessment Criteria Development Index

项目摘要

The purpose of the present study is to explore significant rating criteria and development indices that could be used for assessing L2 (a second language) writing abilities appropriately. As a first step, argumentative essays in English produced by Japanese EFL (English as a Foreign Language) college students were collected and compiled as a learner corpus. These essays were all analytically rated by two native speakers of English.Two kinds of correlation analyses were then performed using rating scores: 1) a correlation analysis between the total scores and their analytical sub-scores in the corpus and 2) a correlation analysis between the total scores and some quantitative values (such as the essay length, average sentence length, and average word length) automatically computed from the essay data. Our findings show that analytic scales "Content" and "Language Use" are significantly correlated with the total score of the essay and that the essay length is also significantly correlated with the total score of the essay. The significantly positive correlation between the total score of the essay and the student's English proficiency was also observed.Since the size of our newly-developed corpus is small, the findings we obtained are not generalizable across all Japanese EFL learners. However, the present research seems to point to a new line of learner corpus-based L2 writing assessment research. The findings from future research are expected to provide some useful insights into classroom teaching of L2 writing.

本研究的目的是探索可用于评估二语写作能力的重要评分标准和发展指标。作为第一步，本研究收集了日本EFL（英语作为外语）大学生的英语议论文，并将其汇编成学习者语料库。这些文章都是由两名以英语为母语的人进行分析性评分的。然后使用评分进行两种相关性分析：1）语料库中总分与其分析分之间的相关性分析; 2）总分与一些量化值之间的相关性分析例如，文章长度、平均句子长度和平均单词长度可以是从文章数据自动计算的。研究结果表明，分析量表“内容”和“语言运用”与作文总分显著相关，作文长度与作文总分也显著相关。作文总分与学生的英语水平之间也存在显著的正相关。由于我们新开发的语料库规模较小，我们获得的结果并不能推广到所有的日本英语学习者。然而，目前的研究似乎指出了一个新的路线，学习者语料库为基础的二语写作评估研究。未来的研究结果有望为二语写作课堂教学提供有益的启示。
