Meta-Analysis of Educational Interventions

What is Meta-Analysis of Educational Interventions?
Meta-analysis of educational interventions statistically combines effect sizes from multiple randomized controlled trials (RCTs) to determine the overall efficacy of programs in reading, language teaching, and skill development.
This approach synthesizes quantitative data from RCTs to compute pooled effect sizes, addressing heterogeneity via I² statistics and publication bias through funnel plots and Egger's test. Turkish studies have applied meta-analysis to listening education (Doğan & Özçakmak, 2014, 53 citations), computer-assisted math (Demir & Başol, 2014, 27 citations), and effect size reporting (Özsoy & Özsoy, 2013, 38 citations). Over 20 foundational theses and 10 recent reviews exist in Turkish educational journals.
Why It Matters
Meta-analyses guide policymakers in scaling effective interventions, such as computer-assisted mathematics programs with moderate effect sizes (Demir & Başol, 2014). They reveal gaps in multicultural education attitudes (Karacabey et al., 2019, 83 citations) and 21st-century skills frameworks (Cansoy, 2018, 128 citations), informing teacher training. In PISA contexts, they predict reading performance impacts on math/science (Koyuncu & Fırat, 2021, 66 citations), enabling evidence-based curriculum reforms.
Key Research Challenges
Heterogeneity in Effect Sizes
Educational RCTs vary by intervention type, student age, and context, inflating I² values above 50% (Yılmaz, 2021). Random-effects models help, but subgroup analyses strain small sample sizes (Doğan & Özçakmak, 2014). Detecting true moderators remains difficult.
Publication Bias Detection
Positive results dominate journals, skewing pooled effects; funnel plot asymmetry occurs in 30% of education metas (Özsoy & Özsoy, 2013). Egger's regression and trim-and-fill adjust, but fail with few studies (Demir & Başol, 2014). Fail-safe N underestimates hidden nulls.
Effect Size Reporting Gaps
Only 20% of Turkish education papers report Cohen's d or Hedges' g consistently (Özsoy & Özsoy, 2013). Inconsistent metrics hinder pooling, as seen in reading theses (Elbir, 2013). Standardization protocols are lacking.
