Subclaims¶

q3 i? Country of evaluation significantly moderated science effects (F = 3.51, p = .03), driven by a significant difference between U.S. (g = 0.46) and Turkish (g = 0.96) studies. → Polanin 2024

Evidence¶

Polanin 2024¶

Polanin, J. R., Austin, M., Taylor, J. A., Steingut, R. R., Rodgers, M. A., & Williams, R. (2024). Effects of the 5E Instructional Model: A Systematic Review and Meta-Analysis. AERA Open. https://doi.org/10.1177/23328584241269866

q3 · i? · quant-synthesis · r3

Exploratory moderator analysis of country (added after the preanalysis plan) for the science domain: "statistically significant differences in effect sizes between studies conducted in the U.S., Turkey, or another country (F = 3.51, p = .03)".

"Further posthoc analyses indicated that the significant difference (p < .01) was between studies conducted in the U.S. (g = 0.46, SE = 0.13) and Turkey (g = 0.96, SE = 0.11)."

q3 · i? · quant-synthesis · r3

In the exploratory meta-regression (Model 1), country coefficients were no longer statistically significant and were considerably smaller than the bivariate moderator estimates, suggesting confounding with other study characteristics.

"our meta-regression model results indicated that studies in Turkey and other-non-U.S. and non-Turkish countries would have consistently lower effects relative to U.S. studies; however, neither of the coefficients were statistically significant (p > .05)"
