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.
q3 i2 Eighth graders using the POED-based VR approach significantly outperformed the POEE-based VR control group in chemistry learning achievement (η2 = 0.12). → Kuan‑Fu Chen 2025

q3 · i2 · causal · r1
Quasi-experiment with 55 eighth graders (28 experimental, 27 control) learning factors affecting chemical reaction rate; ANCOVA with pretest as covariate. The article reports "the experimental group significantly outperformed the control group (F = 7.19, p = 0.01, η2 = 0.12)".
"The results showed that the experimental group significantly outperformed the control group (F = 7.19, p = 0.01, η2 = 0.12), indicating that the POED-based VR approach could effectively enhance students' learning achievement in chemistry."
