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 i3 Groups showed a significantly higher mean proportion of P4 turns and lower proportion of P3 turns on the scaffolded task compared to the non-scaffolded task. → Parks 2026

q3 · i3 · causal · r1
Repeated-measures ANOVA across 11 undergraduate engineering groups comparing turn proportions on scaffolded vs. non-scaffolded tasks. Mean P3 proportion was 0.768 (non-scaffolded) vs. 0.586 (scaffolded); mean P4 was 0.070 vs. 0.221. The article reports "a main effect of task on the proportion of P3" with η2 = 0.644 and P4 with η2 = 0.516.
"A repeated measures analysis of variance indicated a main effect of task on the proportion of P3, F(1,10) = 18.12, p =.002, η2 = 0.644, and the proportion of P4, F(1,10) = 10.67, p =.008, η2 = 0.516."
Discussion¶
Learner Variables¶
- Problem Solving — outcome: instruction changes it
Related Claims¶
- Groups' final solution scores were significantly higher on the scaffolded task than the non-scaffolded task — related
- Groups' distribution of the four problem-solving processes deviated less from the ideal distribution (lower Gini coefficients) on scaffolded than non-scaffolded tasks — related
- Explicit scaffolding prompts elicited P1 (exploring) and P2 (planning) engagement at task start that groups did not show on the non-scaffolded task — related
- Video-graph analysis shows scaffolded tasks produced more diverse process episodes, more fluent transitions between processes, and more P3–P4 oscillation than non-scaffolded tasks — related
