Self-Regulated Strategy Development With and Without Peer Interaction: Improving High School Students’ L2 Persuasive Essay Revisions

High school students for whom English is a second language (L2) often struggle with effective text revision because of limited ability to self-regulate their writing, that is, to manage the subprocesses of writing and to use writing-related knowledge and strategies. To help students in China acquire effective text revision skills for English persuasive essays, self-regulated strategy development (SRSD) revision instruction was applied both with and without peer interaction targeting knowledge of six writing dimensions. An experimental design involving 120 Chinese 11th-grade students in three conditions, that is, SRSD revision instruction with and without peer interaction (two treatment conditions) and conventional instruction without SRSD (control condition), was applied to examine the instructional effects on students’ writing and text revisions. Analyses of covariance revealed a statistically significant increase in text length and improvement in students’ text quality regarding higher-order content-level writing dimensions in both treatment conditions compared to the control condition in a post-intervention test. Notably, the most substantial improvement regarding both text length and text quality was observed in the SRSD plus peer interaction condition. Further, students in both treatment conditions made more text revisions involving longer text segments aimed at improving quality and changing meaning compared to those in the control condition. Among these, the students in the SRSD plus peer interaction condition exhibited the highest frequency of high-quality text revision during the posttest. The findings provide new insights into the effectiveness of SRSD revision instruction and peer interaction in developing L2 high school students’ self-regulation in revising English persuasive essays.
