Sustaining University English as a Foreign Language Learners' Writing Performance through Provision of Comprehensive Written Corrective Feedback

Writing is regarded as a crucial skill in English language curricula at the secondary and tertiary levels in the Chinese education system. Currently, Chinese teachers of English as a foreign language (EFL) often adopt a product approach to teaching EFL writing, in which they emphasize the quality of their students' written products and show little concern with the writing process. To help L2 learners achieve sustainable development of their writing proficiency, teachers employ a comprehensive approach to correct their students' language errors as a common practice. However, empirical studies regarding its efficacy on different dimensions of L2 writing are insufficient. This study intended to fill this lacuna in a Chinese EFL context, which investigated the effects of sustained comprehensive written corrective feedback (WCF) on accuracy, complexity, fluency, and content and organization quality of EFL students' writing. Quasi-experimental in design, it involved a comparison group and a treatment group receiving four sessions of direct comprehensive WCF. Results show that such WCF contributed to writing accuracy and fluency over time. Our textual analysis further reveals that it particularly benefited students' grammatical accuracy, reducing some rule-based grammatical error types. However, it showed limited effects on complexity, content, or organization of students' writing. Interestingly, the comparison group did not improve any dimensions of their writing. Possible implications are also discussed.
