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 With initial instruction, participants using retrieval practice scored significantly higher on the final generalization test than those studying worked examples (ηp² = .10). → Meng Cao & Paulo F. Carvalho 2026

Experiment 1, a mixed-design online experiment (2 variability × 2 strategy, strategy within-subjects, 39 participants per variability group after exclusions), tested transfer on 25 novel items. Retrieval practice beat worked examples with a printed effect size of ηp² = .10 ("F(1,76) = 8.08, p = .006, ηp 2 = .10").

"worked examples, F(1,76) = 8.08, p = .006, ηp 2 = .10 (see Fig. 2). The interaction between variability and learning strategy was not significant, F(1,76) = 0.02, p = .877"
