New AI framework enhances math grading by detecting AI assistance

By PulseAugur Editorial · [1 sources] ·

Researchers have developed AICG, a novel framework for automated mathematical short answer grading that addresses limitations in current AI-based systems. AICG utilizes a two-branch multi-task approach, with one branch focusing on individual answer grading using RoBERTa and the other associating responses with assessed skills via a Q-matrix to predict mastery and learning gain. A key innovation is the integration of a Generative AI detector that estimates assistance probabilities, converting them into reliability weights to mitigate unreliable cognitive evidence during learning assessment. Experiments on a large dataset demonstrated that AICG significantly reduces mean absolute error and improves grading accuracy compared to standard RoBERTa regression. AI

IMPACT This framework could improve the accuracy and fairness of automated grading systems, especially in subjects like mathematics where AI-generated content is prevalent.
