q3 i? Across PD studies, larger teacher-level impacts were linked to significantly larger mean impacts on student achievement. → Lynch 2025

Lynch, K., Gonzalez, K., Hill, H., & Merritt, R. (2025). A Meta-Analysis of the Experimental Evidence Linking Mathematics and Science Professional Development Interventions to Teacher Knowledge, Classroom Instruction, and Student Achievement. AERA Open. https://doi.org/10.1177/23328584251335302

q3 · i? · quant-synthesis · r?

Meta-analytic regression approach linking per-contrast mean effect sizes for teacher outcomes (all outcomes, knowledge, and instruction separately) to student achievement impacts. The article reports the link was "signifi- cantly larger" without printing a coefficient or effect size, so no magnitude is coded.

"Programs with larger impacts on teacher-level outcomes also tended to have signifi- cantly larger mean impacts on student achievement."

Related Claims¶

• Prior meta-analyses report moderate positive pooled effect sizes of teacher PD on instructional practice and teacher knowledge outcomes — related
• Prior meta-analysis reports a pooled mean effect size of 0.21 SD on student achievement for mathematics and science teacher PD and curriculum improvement interventions — related
• Mathematics and science PD interventions causally improve in-service teachers' knowledge and classroom instruction, with a pooled average impact estimate of +0.52 SD across randomized studies — related
• Teacher coaching programs improve teachers' instructional practice by a pooled 0.49 SD across 43 causal studies — related
• A practitioner review reports a meta-analysis of causal coaching studies as finding positive effects of coaching on teachers' instructional practice and student achievement, though one contrasting study found coached teachers no more effective — related
• Teachers with higher Framework for Teaching scores tended to make larger contributions to student achievement (value added) — related
• In elementary grades, students in schools with extensive standards-related professional development reported significantly larger improvements in academic demand, rigor, instructional clarity, and teacher support than students in schools with limited professional development — related
• The Math Solutions video-based PD program showed limited impact on teacher knowledge and no impact on instructional practice or student achievement — a narrower finding that bears on this claim
• Educators tend to perceive meaningful effects of the developers' curricula on student outcomes, but standardized measures tend not to reflect the same level of impact as proximal assessments — related
