A new research paper introduces Truncated Reasoning AUC Evaluation (TRACE) as a method to detect answer-driven reasoning in LLM-based educational tutors. The study found that when LLMs like Qwen2.5-3B-Instruct have access to answer keys, their explanations become significantly more likely to reveal the correct answer early in the generated text. This suggests that LLMs may be generating explanations that are tailored to already know the answer, rather than deriving the answer from the problem itself. AI
