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? There was no significant interaction between condition and prior knowledge level on immediate or delayed gains, and the delayed advantage was significant within both low (d=.35) and high prior knowledge (d=.37) subgroups. → Bruce M. McLaren & Deanne M. Adams & Richard E. Mayer 2015

q3 · i? · causal · r2

Median-split analysis (200 low, 190 high prior knowledge) plus a stepwise regression on pretest as a continuous variable found "no significant interaction between condition and prior knowledge level". Separate ANCOVAs showed significant delayed gains for both subgroups (d=.35 and d=.37).

"However, there was no significant interaction between condition and prior knowledge level for gains between either the pretest to the immediate posttest (F(1386)=.36, MSE=145.69, p=.55) or pretest to the delayed posttest F (1386)=.67, MSE=27.44, p=.41)."
