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? The quantity of generated solutions did not mediate the effect of condition on conceptual knowledge, and neither path of this mediation was significant. → Charleen Brand 2023
Evidence¶
Charleen Brand 2023¶
Charleen Brand, Christian Hartmann, Katharina Loibl, Nikol Rummel. (2023). Do students learn more from failing alone or in groups? Insights into the effects of collaborative versus individual problem solving in productive failure. Instructional Science. https://doi.org/10.1007/s11251-023-09619-7
q3 · i? · causal · r2
Mediation analysis (N = 135, PROCESS model 82, 5000 bootstrap samples, cluster-corrected standard errors) in the randomized PF experiment. The indirect effect through solution quantity was a1b1 = 0.01 with a confidence interval including zero.
"The bootstrap confidence interval showed no evidence for an indirect effect of the condition on conceptual knowledge that is mediated through quantity of solutions, a1b1 = 0.01, SE = 0.05, 95% CI [− 0.06, 0.14]."
