Subclaims¶

q2 i? Groups showed more diversity of process turns, more uninterrupted transitions between processes (37 vs. 28 instances), and more oscillation between solving and evaluating on the scaffolded task. → Parks 2026

q2 · i? · causal · r1

Qualitative video-graph comparison of thematic episodes across 11 groups' transcripts. "There are 37 instances depicted in the graphs of groups transitioning between problem-solving realms without a break for the scaffolded task, whereas in the non-scaffolded task this is depicted 28 times." All but two groups oscillated between P3 and P4 on the scaffolded task.

Discussion¶

Learner Variables¶

• Problem Solving — outcome: instruction changes it

Related Claims¶

• Groups' distribution of the four problem-solving processes deviated less from the ideal distribution (lower Gini coefficients) on scaffolded than non-scaffolded tasks — related
• 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
• Explicit scaffolding prompts elicited P1 (exploring) and P2 (planning) engagement at task start that groups did not show on the non-scaffolded task — related
• Groups' final solution scores were significantly higher on the scaffolded task than the non-scaffolded task — related
