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 A repeated-measures ANOVA showed a main effect of task on groups' final solution scores, with scaffolded task scores significantly higher on average. → Parks 2026

q3 · i3 · causal · r1
Repeated-measures ANOVA on rubric-scored final solutions from 11 groups. Scores were out of 5 for the non-scaffolded task and 6 for the scaffolded task (adjusted to a 5-point scale). "a main effect of task on the groups' scores, F(1,10) = 4.36, p =.044, η2 = 0.713" indicates higher solution quality on the scaffolded task.
"A repeated measure analysis of variance indicated a main effect of task on the groups' scores, F(1,10) = 4.36, p =.044, η2 = 0.713. These results indicate that the quality of groups' final solutions for the scaffolded task was significantly higher on average than the quality of the groups' final solutions for the non-scaffolded task."
Discussion¶
Learner Variables¶
- Problem Solving — outcome: instruction changes it
Related Claims¶
- Scaffolded ill-structured tasks elicit a higher proportion of solution-evaluation (P4) turns and a lower proportion of problem-solving (P3) turns than non-scaffolded tasks — 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
- 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
- The scaffolding intervention unintentionally increased small groups' independent working time, roughly doubling it from premeasurement to postmeasurement — related
- Teachers who completed a scaffolding intervention program increased the contingency of their support far more than non-participating teachers — related
