Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q4 i? Heterogeneity was high (I² > 95%), indicating significant variability across studies. → Björn Haßler 2025

q4 · i? · quant-synthesis · r3
The same pooled meta-analysis reported very high heterogeneity across included studies, described in the text as "high (I² > 95%)". No moderator fully explains the variability.
"However, heterogeneity was high (I² > 95%), indicating significant variability across studies."
Discussion¶
Related Claims¶
- EdTech's direct effect on student attitudes is small and non-significant (d = 0.1308), but attitudes correlate significantly with attainment (r = 0.694) — a narrower finding that bears on this claim
- EdTech interventions significantly improve student motivation (d = 0.375), but motivation does not significantly correlate with attainment (r = 0.608, p = 0.2763) — related
- Intensive mathematics interventions for K-3 students with or at risk for MD yield an overall pooled mean effect size of β = 0.61 with substantial heterogeneity — a broader claim this one bears on
- Emerging technologies show a small-to-moderate positive overall effect on TEFL outcomes (g = 0.38, corrected to 0.28 for publication bias) — related
- GenAI-supported writing instruction yields a statistically significant positive pooled effect on L2/EFL writing performance (g = 0.80) with very high heterogeneity — related
- Technology-supported educational interventions are associated with higher metacognitive outcomes on average (g = 0.653), with substantial between-study heterogeneity — related
- Flipped classrooms are associated with higher theoretical knowledge scores than lecture-based teaching in medical education (pooled SMD = 1.26), with very high heterogeneity — related
- Gamified flipped classroom/animation knowledge effects are inconclusive due to few studies and extreme heterogeneity — related
