Subclaims¶

q2 i? Four groups engaged in exploring the problem (P1) at the start of the scaffolded task but not the non-scaffolded task; four groups engaged in planning (P2) during the first half of the scaffolded task but not the non-scaffolded task. → Parks 2026

q2 · i? · causal · r1

Video-graph episode analysis of 11 groups. "Four groups responded to the prompt to engage in exploring the problem at the start of the scaffolded task, but did not during the non-scaffolded task." Similarly, four groups engaged in P2 during the first half of the scaffolded task only, and five more showed more P2 there.

"Four groups responded to the prompt to engage in exploring the problem at the start of the scaffolded task, but did not during 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
• Minimal guidance is less effective for novices than explicit instruction — a broader claim this one bears on
• 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
• Groups' distribution of the four problem-solving processes deviated less from the ideal distribution (lower Gini coefficients) on scaffolded than non-scaffolded tasks — related
