Subclaims¶

q2 i? In a questionnaire-based expert evaluation with 32 STEM instructors, PIVOT consistently outperforms the baseline across nearly all evaluation dimensions, with an average gain of +1.67 points in Physics and +0.76 in Computer Science. → Xinchen Ma 2026 q2 i? The largest improvement is observed in Error Explanation, suggesting misconception-aware remediation improves conceptual understanding. → Xinchen Ma 2026 (2)

q2 · i? · design · r2

Questionnaire-based expert evaluation with 32 STEM instructors (3 physics, 12 mathematics, 5 chemistry, 12 computer science) on five-point Likert items, with display order randomly shuffled; Figure 3 reports ratings across seven dimensions in four STEM domains.

"Physics shows an average gain of +1.67 points over the baseline across comparable dimen-sions, while Computer Science improves by +0.76 points."

q2 · i? · design · r2

In the same expert evaluation, the authors interpret the largest dimension-level gain as showing that "misconception-aware remediation improves both conceptual understanding"; this is the authors' interpretation of rating differences, not a learner outcome measure.

"Notably, the largest improvement is observed inError Explanation, suggesting that misconception- aware remediation improves both conceptual under- standing and potential learning effectiveness by cor- recting learner misunderstandings."
