Subclaims¶

q2 i? For the learn parameter P(T), all posterior contrast estimates were centered near zero with credible intervals spanning zero for both spacing and color cues; equivalence was not tested. → Siddhartha Pradhan 2026

Evidence¶

Siddhartha Pradhan 2026¶

Siddhartha Pradhan, Yanping Pei, Morgan Lee, Puyuan Zhang, Erin Ottmar, and Adam C. Sales. (2026). StanBKT: Rethinking Parameter Estimation in Bayesian Knowledge Tracing. https://arxiv.org/abs/2605.23048 doi:10.48550/arxiv.2605.23048

q2 · i? · design · r2

Null finding from the posterior contrasts in Table 7 of the Multi BKT reanalysis of the perceptual cue intervention (688 students, nine conditions). "no credible effects are observed" for the learning rate; the article reports credible intervals spanning zero rather than a formal equivalence test.

"ForP(T), no credible effects are observed, with all estimates centered near zero and credible intervals spanning zero across both spacing and color cues, indicating no meaningful influence on learning rate."

• In the perceptual-cue reanalysis, the only reliable forgetting and slip deviations were a small forgetting reduction under incongruent color and a modest slip reduction under congruent spacing — related
• In a perceptual-cue intervention reanalysis, incongruent spacing and incongruent color conditions were associated with reduced guessing relative to neutral conditions — related
• Readers' judgment explanations support a cautious hierarchy of perceptual cues: content, then color, then space, then graphic features — related
