作文自动评价系统已成为写作反馈一种不可忽视的形式。迄今鲜有论文专门探讨作文自动评价系统是否会影响学生写作中的语言复杂性以及如何影响的问题。该研究在较长的实验周期内检验了句酷批改网对学生写作中词汇复杂性和句法复杂性的影响。文章使用了双因素重复测量方差分析等统计方法,分析了三个水平组 45 名学生在 32 周的时间里在批改网上完成的作文,结果发现,基于批改网的作文自动评价有利于学生语言复杂性的发展,同时有无混合教师人工批阅对句法复杂性的影响大于词汇复杂性的影响。

Automated writing evaluation (henceforth AWE) has become an issue of substantial controversies and debates, as well as a source of written feedback that can’t be ignored. So far there are few researches exploring whether and how AWE impacts the complexity of students’ writings. The current study examined the effectiveness of Juku Pigai Website on the lexical and syntactic complexity of students’ writing. The participants were 45 homogeneous average learners in College English class; they were divided into three groups according to three feedback modes, including two experimental groups —a Pigai feedback only and Pigai with human instruction —and a control group using global scoring. Statistical methods, such as two-way repeated measures ANOVA, were used to measure the linguistic properties of the compositions written in 32 weeks on Pigai Website. The result revealed a significant gain for the complexity in both experimental groups using AWE provided by Pigai Website; the experimental group using Pigai Website assisted by human feedback shows greater changes in syntactic complexity than in lexical complexity.
