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 i? In Experiment 2 the contrast on the transfer test was not significant. → Lachner 2020 q3 i? In Experiment 1 none of the contrasts on the transfer test were significant. → Lachner 2020 (2)

q3 · i? · causal · r2

In Experiment 2's contrast analysis on the two-question transfer test (gas turbine and two-stroke engines), the contrast was not significant, "F(1, 121) = 1.43, p = .234, ηp2 = .012"; transfer performance was very low across conditions.

"Regarding students' transfer, as in Experiment 1 the contrast was not significant, F(1, 121) = 1.43, p = .234, ηp2 = .012."

q3 · i? · causal · r2

In Experiment 1, contrast analyses on the transfer test showed no significant contrasts (F < 1), with similar and very low transfer performance across the three conditions.

"Regarding students' performance on the transfer test, contrary to our expectations, none of the contrasts were significant (F < 1), indicating that students showed similar (and very low) transfer performance across all experimental conditions"
