Research questionHow can language models produce reliable educational answers with reasoning that is verifiable?Language models may produce correct-looking answers while giving explanations that are inconsistent, weakly grounded, or difficult to check. Educational question answering therefore requires both reliable answers and reasoning that can be validated.

The evidence covers a Qwen2.5-3B-Instruct-based system using formal-logic, formula-, and unit-aware verification, evaluated on 438 held-out examples; the reported gains were stronger for reasoning depth than for hybrid answer correctness.research paper · Sep 4, 2026
