Science Writing Interventions and Student Achievement: A Systematic Review and Meta-Analysis (Stage 3, 2:08 PM)

• In Event: e-Lightning Ed-Talk Session 4 - Stage 3

Abstract

This meta-analysis synthesizes 10 experimental studies (N = 3,255) to examine the effects of science writing interventions on K–12 students’ science and writing achievement. Grounded in cognitive and sociolinguistic frameworks, the study explores writing genre, grade level, and outcome domain as moderators. Robust variance estimation revealed a significant overall effect (g = 0.726), with explanatory writing yielding stronger outcomes than argumentative writing. Moderator analysis showed limited but suggestive genre-based variation. Findings support writing-to-learn as a promising instructional strategy in science education and underscore the importance of genre-sensitive scaffolding. Implications are discussed for equitable, literacy-integrated science instruction.
