As evidence becomes increasingly important in educational policy, it is essential to understand how research design might contribute to reported effect sizes in experiments evaluating educational programs. A total of 645 studies from 12 recent reviews of evaluations of preschool, reading, mathematics, and science programs were studied. Effect sizes were roughly twice as large for published articles, small-scale trials, and experimenter-made measures, compared to unpublished documents, large… Expand
Investigating Science Education Effect Sizes: Implications for Power Analyses and Programmatic Decisions
TLDR
This meta-analysis examines the relationship between science education intervention effect sizes and a host of study characteristics, allowing primary researchers to access better estimates of effect sizes for a priori power analyses and support programmatic decisions by setting realistic expectations about the typical magnitude of impacts for science education interventions. Expand
Interpreting Effect Sizes of Education Interventions
Researchers commonly interpret effect sizes by applying benchmarks proposed by Jacob Cohen over a half century ago. However, effects that are small by Cohen’s standards are large relative to theExpand
Do Published Studies Yield Larger Effect Sizes than Unpublished Studies in Education and Special Education? A Meta-review
Meta-analyses are used to make educational decisions in policy and practice. Publication bias refers to the extent to which published literature is more likely to have statistically significantExpand
Peer tutoring and mathematics in secondary education: literature review, effect sizes, moderators, and implications for practice
TLDR
Conclusions suggest the implementation of same-age over cross-age tutoring, during programs of fewer than 8 weeks, in sessions of less than 30 minutes is optimal for improving students' academic outcomes. Expand
The perspective of “limited malleability” in educational effectiveness: treatment effects in schooling
ABSTRACT In this article, several ways to adjust gross school effects are discussed to set the stage for estimating treatment effects in schooling. Although it is quite hazardous to hypothesizeExpand
Effects of policy and educational interventions intended to reduce difficulties in literacy skills in grade 1
Abstract In two large-scale studies, the effects of policy and educational interventions on literacy skills were examined in children schooled in zones with specific educational needs. To calculateExpand
