q2 i? Among high-prior students, %KBR correlated with CKTpre (r(9) = 0.76, p < 0.05) and PSTpre (r(9) = 0.64, p < 0.05). → Fathima Ameen 2026 q2 i? Among low-prior students, %KBR did not correlate with CKTpre (r(9) = 0.21, p = 0.54) or PSTpre (r(9) = 0.15, p = 0.67). → Fathima Ameen 2026 (2)

Evidence¶

Fathima Ameen 2026¶

Fathima Ameen, Tasmia Shahriar, Aditi Mallavarapu, Shiyan Jiang, Noboru Matsuda. (2026). Beyond prior knowledge: the predictive role of knowledge-building in tutor learning. Behaviormetrika. https://doi.org/10.1007/s41237-026-00294-9

q2 · i? · associational · r?

Pearson correlations on the median-split groups from the classroom study; among high-prior students %KBR and pre-test scores "were highly correlated", consistent with their knowledge-building capacity being already developed.

"correlation analyses showed that among high-prior students, CKT pre and %KBR were highly correlated, r (9) = 0 .76,p < 0.05, as were PST pre and %KBR, r (9) = 0 .64,p < 0.05."

q2 · i? · associational · r2

Pearson correlations among low-prior students in the same ad hoc analysis; neither correlation was significant, suggesting their knowledge-building responses "may not be determined by prior understanding but rather through interaction with the adaptive questioning framework."

"the correlation between %KBR and CKTpre was not significant for low- prior students, r (9) = 0.21, p =0 .54, nor was the correlation between %KBR and PST pre, r (9) = 0.15, p =0 .67."

Discussion¶

Learner Variables¶

• Prior Knowledge — predictor: learners who differ on it differ in outcomes

• Tutors' proportion of knowledge-building responses to an agent's adaptive follow-up questions predicts conceptual and procedural post-test scores — related
• Prior conceptual and procedural knowledge did not significantly predict tutors' proportion of knowledge-building responses — reports the opposite
• Low-prior-knowledge tutors with high %KBR outperformed their low-%KBR counterparts at post-test and scored statistically equivalent to high-prior peers — related
• Tutors showed significant pre-to-post gains in both conceptual knowledge and procedural skill after teaching with adaptive follow-up questioning — related
