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 i? Introductory biology students randomly assigned to PS-I scored significantly higher than I-PS students on the near-transfer post-test, controlling for prior knowledge. → Cheng-Wen He 2025

q3 · i? · causal · r3

Randomized classroom experiment with 367 introductory biology students assigned to I-PS (n=183) or PS-I (n=184), analyzed with non-parametric Quade ANCOVA controlling for prior knowledge test score. The results indicated that "significantly outperformed the I-PS students" on near transfer, supporting the productive failure hypothesis.

"the PS-I students ( M=6 .34,SD = 4.21 ) significantly outperformed the I-PS students ( M=5 .07,SD = 3.76 ) on the near-transfer test, F(1,365) = 7.18 , p = .008"
