This study evaluates the effectiveness of blended learning for enhancing graduate students’ academic writing and delineates design features associated with improved outcomes. Building on evidence that blended environments can yield performance advantages over purely face-to-face or fully online instruction in higher education (Means et al., 2010; Bernard et al., 2014) and theoretical accounts of their potential to support deep, feedback-rich learning (Garrison & Kanuka, 2004), we conducted a systematic review of empirical studies targeting graduate-level academic writing. Searches across ERIC, PsycINFO, Scopus, and Web of Science (2000–2024) identified studies that implemented blended interventions aimed at research writing or genre-based academic prose, included a comparison condition, and reported performance outcomes using validated rubrics or analytic measures. Risk of bias was appraised using established criteria, and findings were synthesized via random-effects meta-analysis where feasible and narratively otherwise. Across a small, heterogeneous body of eligible studies, blended approaches were generally associated with positive—often small-to-moderate—gains in writing quality and writing self-efficacy relative to traditional or single-mode instruction. Interventions that integrated explicit genre pedagogy (Hyland, 2004), iterative drafting with timely formative feedback and peer review (Nicol & Macfarlane-Dick, 2006), and structured support for scholarly writing practices (e.g., writing groups and supervisor-mediated feedback; Aitchison & Lee, 2006) were more consistently linked to improvement. However, the precision of pooled estimates was constrained by limited sample sizes, variability in outcome measures, and incomplete reporting. The findings support the promise of blended learning to enhance graduate academic writing when designs intentionally combine explicit genre instruction, scaffolded practice, and multi-source feedback aligned with self-regulated learning principles. Future research should employ preregistered, adequately powered trials with common outcome metrics to strengthen causal inference and to isolate active design components. References: Bernard, R.
