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? Inferences during free recall did not differ between the relevant-problem group (mean 9.56) and the control group (mean 11.19) when recall was tested immediately after study. → W.S. de Grave 2001

q3 · i? · causal · r2
Null ANOVA on inference counts from the same randomized study; the article reports means of 9.56 (SD 6.19) for the relevant-problem group and 11.19 (SD 5.45) for controls. Equivalence was not tested.
"Analysis of variance, however, yielded no significant differences between the two groups with respect to the number of inferences during recallF(1,46) = 0.914,MSe = 34.56, p< 0.34"
Discussion¶
Related Claims¶
- Problem-based tutorial discussion of a relevant problem before studying an expository text increases the number of accurate propositions recalled from that text — related
- Participating in a relevant group discussion, whether explaining or listening, raises immediate recall relative to an irrelevant discussion, but this advantage does not persist one month later — related
- The recall benefit of prior problem-based discussion applies to both explanatory and descriptive propositions, with no interaction between treatment and proposition type — related
- Elaboration during a problem-based discussion interacts with relevant prior knowledge on immediate text recall, with the interaction approaching significance at a medium effect size — related
- Prior problem-based discussion does not change the number of inaccurate propositions recalled — related
- Analyzing a problem before reading facilitates subsequent recall of a relevant text for both novices and experts — related
- Problem analysis through small-group discussion particularly stimulates the production of explanatory propositions, via a significant treatment-by-proposition-type interaction — related
