Description¶
The article formalizes misconception acquisition from two perspectives. The Novice Student Misconception Model simulates an individual student holding one specific misconception and must satisfy Misconception Replication on applicable types plus Correct Reasoning Preservation on non-applicable types. The Expert Tutor Misconception Model captures the spectrum of misconceptions a tutor encounters across students, a computational analogue of teachers' Knowledge of Student Misconceptions, and must replicate every training misconception while maintaining Overall Correct Accuracy across all problem types. Both use thresholds where "We setθm =θ c = 90%in all experiments."

Claims¶
- Instruction-tuning a student model on a single misconception overgeneralizes the error across problems and degrades correct-solving accuracy [+M]
- Tutor models trained on ten misconceptions simultaneously learn each misconception while overall correct accuracy remains stable or improves (93% to 98%) [+M]
- Mixing correct examples into student-model training resolves the misconception-accuracy trade-off, with correct examples as low as 25% preserving both properties [~M]
