This addresses a meta-reasoning bottleneck in LLMs for educational applications, but it is incremental as it builds on existing error detection tasks.

The paper tackled the problem of LLMs failing to locate the first error step in stepwise math solutions, even with access to reference solutions, and proposed a method that generates corrected intermediate solutions to improve performance, achieving gains on datasets like VtG and PRM800K.

Large language models (LLMs) demonstrate remarkable performance on math word problems, yet they have been shown to struggle with meta-reasoning tasks such as identifying errors in student solutions. In this work, we investigate the challenge of locating the first error step in stepwise solutions using two error reasoning datasets: VtG and PRM800K. Our experiments show that state-of-the-art LLMs struggle to locate the first error step in student solutions even when given access to the reference solution. To that end, we propose an approach that generates an intermediate corrected student solution, aligning more closely with the original student's solution, which helps improve performance.
