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? Condition interacted with prior knowledge on conceptual knowledge (F(2, 166) = 3.13, p = 0.047); the moderation coefficient was b 3 = 0.34, p = 0.011. → Christian Hartmann 2021
q3 i3 Within conditions, prior knowledge correlated strongly with conceptual post-test performance in VF-process (r = 0.53) but not in PF (r = 0.13, non-significant). → Christian Hartmann 2021 (2)

q3 · i? · causal · r2
Regression moderation analysis (PROCESS Model 1) following up the significant condition × prior knowledge interaction, F(2, 166) = 3.13, p = 0.047, found "prior knowledge significantly moderated the effect on conceptual knowledge in the PF and the VF-process conditions, b 3 = 0.34, p = 0.011". No standardised effect size was printed for the moderation.
"prior knowledge significantly moderated the effect on conceptual knowledge in the PF and the VF-process conditions, b 3 = 0.34, p = 0.011"

q3 · i3 · causal · r2
Follow-up simple-correlation analyses within conditions: in VF-process prior knowledge correlated with the conceptual post-test at r = 0.53, p < 0.001 (a large printed effect size), whereas in PF the correlation was r = 0.13, p = 0.345 and not significant.
"While prior knowledge did not affect the post-test performance in the PF condition, r(55) = 0.13, p = 0.345, students in the VF-process condition gained more from observing the process when they had higher prior knowledge, r(56) = 0.53, p < 0.001"
Discussion¶
Learner Variables¶
- Prior Knowledge — moderator: an instructional effect differs with it
Related Claims¶
- Instructional guidance that helps novices can become redundant or counterproductive as expertise grows. — the general claim this finding bears on, with the studies behind it
- PF students reported more awareness of knowledge gaps than example observers, but awareness of knowledge gaps did not correlate with conceptual knowledge acquisition — related
- Observing the complete problem-solving-and-failing process (VF-process) was more effective for conceptual knowledge acquisition than generating one's own failed solutions (PF) prior to instruction — related
- Students who generated their own solutions or observed the full process did not significantly outperform students who only viewed the outcomes of failed solution attempts on conceptual knowledge — related
- The three preparatory conditions did not differ on procedural knowledge acquisition — related
- Productive Failure Improves Conceptual Learning — related
- Ability moderates the hierarchical-organization advantage: low-ability subjects showed no significant benefit, while medium-ability subjects did — related
- Neither the quantity nor the quality of PF students' own solution attempts correlated with their conceptual knowledge acquisition — related
- Vicarious failure with high solution diversity is as effective as engaging in Productive Failure oneself for conceptual knowledge acquisition — related
- Prior knowledge score did not significantly moderate the sequence effect within either experiment, though each experiment covered a restricted prior-knowledge range — reports the opposite
- Contrasting cases without explicit guidance on their use showed no significant effect on conceptual understanding or solution-attempt quality — related
- Improvement in conceptually-laden in-game challenges over gameplay is strongly moderated by prior physics knowledge — related
- Students observing high-diversity vicarious failure (VF-high) significantly outperform students in VF-low and DI conditions on conceptual knowledge — related
- Collaborative and individual problem solving in traditional PF do not differ in conceptual knowledge after instruction — related
