Dynamic Written Corrective Feedback in First-Year Composition: Accuracy and Lexical and Syntactic Complexity

First-year composition courses must balance a range of writing instruction priorities including genre and audience awareness with language instruction, particularly for second-language writers. Despite the attested efficacy of "dynamic" written corrective feedback for language gains in intensive English programs, little research has investigated dynamic written corrective feedback in supporting language and discourse development among L2 first-year composition students. In the present study, pre- and post-test writing from 63 second-language first-year composition writers was analyzed for grammatical accuracy as well as lexical and syntactic complexity. Writers with dynamic written corrective feedback intervention (n = 30) failed to outperform a control group on nearly all measures, and in fact made significantly more verb errors and demonstrated significantly less syntactic complexity over time compared to the control group. Results suggest that while dynamic written corrective feedback is efficacious in some settings, it may be at cross purposes with other first-year composition discourse-based goals such as genre and audience awareness.
