Meta-analyses aim to provide educators with relevant evidence to guide their decisions in practice. However, a new meta-review by Pellegrini and colleagues examined whether education meta-analyses actually use strategies that make findings relevant, applicable, and accessible to practitioners.
The researchers reviewed 103 meta-analyses of school-based academic interventions published between 2021 and 2023, coding for stakeholder engagement in the review process, reporting of study characteristics, and accessibility of findings through effect size metrics and visualizations.
Results revealed limited attention to practitioner needs. Most reviews (83%) did not mention involving stakeholders in the research process. While certain study characteristics were commonly reported—such as grade level (81%) and intervention type (62%)—others important for decision-making were rarely considered. Notably, no reviews reported the cost of materials or teacher training, information essential for educators assessing whether programs fit their contexts.
Regarding accessibility, only six reviews transformed effect sizes into metrics more meaningful for practitioners (such as Cohen’s U3). Forest plots were the most common visualization (56%), despite evidence that non-researchers find them difficult to interpret. About 39% of reviews included no visualizations at all. Only half of the reviews discussed implications for practice.
The authors concluded that while meta-analyses have potential to inform educational practice, researchers need to better engage stakeholders, report characteristics relevant to implementation decisions, and present findings in accessible formats.
