Subclaims¶

q3 i? Students taught by trained teachers outperformed those in the control condition, both in the experimental (estimated difference of 12.31, 95% CI [0.34, 21.86]) and training (15.15, 95% CI [0.84, 31.10]) conditions. → Luiz Rodrigues 2026 q3 i? The experimental and training conditions did not differ from each other (−4.33, 95% CI [−17.29, 7.23]). → Luiz Rodrigues 2026

q3 · i? · causal · r2

Robust linear mixed models nesting 221 students within 19 classes tested learning gains (IRT proficiency difference, 0–100 scale) across three randomly assigned classroom conditions. The article reports the experimental condition "outperformed the Control one" with Est = 12.31, while experimental and training conditions did not differ.

"the Experimental condition outperformed the Control one (Est = 12.31, SE = 5.77, t = 2.13, CI [0.34, 21.86]), as did the Training condition (Est = 15.15, SE = 10.15, t = 1.49, CI [0.84, 31.10]). In contrast, the Experimental and Training conditions did not differ (Est = −4.33, SE = 5.93, t = −0.73, CI [−17.29, 7.23])."
