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 i2 Across 35 experimental and quasi-experimental studies, AI-supported instructional interventions produced a statistically significant positive overall effect on STEM student achievement (g = 0.670, 95% CI [0.491, 0.848]). → Doğan Yunus 2026
q4 i? The included studies showed a significant and high level of heterogeneity (Q = 199.76, I2 = 82.98% under the fixed-effect model), indicating the effect is context-sensitive rather than uniform. → Doğan Yunus 2026 (2)

q4 · i2 · quant-synthesis · r3
Random effects model meta-analysis of 35 experimental and quasi-experimental studies of AI-supported instruction in STEM, with Hedges' g calculated from post-test means, standard deviations, and sample sizes. The article reports "g = 0.670 (95% CI [0.491, 0.848])" with Z = 7.35, p < 0.001.
"Under this model, the effect size was found to be g = 0.670 (95% CI [0.491, 0.848]), with Z = 7.35 and p < 0.001, while the between-study variance was accounted for more appropriately under the REM (I2 = 15.75%)."

q4 · i? · quant-synthesis · r3
Fixed-effect analysis of the same 35 studies quantified between-study inconsistency with the Q test and I2 statistic, showing "a significant and high level of heterogeneity", which the authors say means effect sizes do not display a homogeneous distribution.
"The meta-analytic findings indicate that there is a significant and high level of heterogeneity among the included studies (Q = 199.76, I2 = 82.98%)."
Studies bearing on this claim¶
Does building AI tools into instruction raise achievement over teaching the same content without them, and in which settings? This table gathers the studies behind this claim and the 10 narrower claims that bear on it: 9 distinct studies (3 causal, 3 design, 2 review, 1 quant-synthesis), q2–q4, 4 of 9 with an effect size coded. One row per study, codes as each entry records them; no effect is averaged and no verdict is drawn. Built by scripts/synthesize_claim.py from eval/synthesis/; a row that looks wrong is fixed on the claim it comes from.
