Engaging in dialogic peer feedback in L2 writing development: A microgenetic approach

Recent research on the multifaceted nature of student engagement indicating that students engaged with peer feedback dynamically, varying with the interaction of individuals and the environment, while neglecting the impact of engagement with peer feedback on L2 learners’ writing development. Grounded in sociocultural theory, this longitudinal case study aimed to investigate the roles of dialogic peer feedback as a mediating tool for promoting L2 writing development. Four first-year English major students participated in eight tutorials over 16 weeks in a university in China. Data were collected from peer feedback dialogue, pre- and post-mediation drafts, retrospective verbal reports, self-reflection, and focus groups through microgenesis. The findings revealed that dialogic peer feedback enhanced student engagement from various dimensions. Engaging in dialogic peer feedback facilitated the diagnosis of writing problems and appropriate mediation through interaction. Mediation rather than correction in dialogic peer feedback was critical in assisting learners in achieving L2 writing goals.
