Subclaims¶

q3 i? 52.3% of impasse turns occurred while identifying relevant concepts, 18.1% during strategy, and 14.5% during execution, and impasse type depended strongly on practice (χ2(10) = 2313.9, p<.001, Cramér's V=.42). → Ahtisham 2026

Cross-tabulation of 6,630 impasse turns across eight problem-solving practices in 1,260 authentic tutoring sessions, with a Pearson χ2 test of independence. The article reports "Impasses were concentrated in the planning phases of problem solving" and impasse type depended strongly on practice (χ2(10) = 2313.9, p<.001, Cramér's V=.42).

"Impasses were concentrated in the planning phases of problem solving (Table 2): 52.3% occurred while identifying relevant concepts, 18.1% during strategy development, and 14.5% during execution."

Related Claims¶

• Early dropouts are trapped in recursive concept-elicitation loops before reaching problem execution — related
• Next-turn recovery from impasses declines steadily as impasse depth increases, with help-seeking impasses declining most sharply — related
• Prompt specificity changes AI tutor pedagogy: a no-direct-answer guardrail alone produces uniform questioning, while a detailed guided protocol produces varied, impasse-sensitive responses — related
• The association between tutor questioning and impasse recovery decays as impasses persist, while addressing the student's error becomes more beneficial — related
• After a failed scripted question, repeating it is followed by lower recovery than switching to addressing the student's error — related
