However, in the field of mathematics, the existing QDA methods still face three challenges: (1) Lack of labeled data: The mainstream machine learning methods rely on real difficulty labels, but the commonly used datasets (such as Math23K, Ape210K) lack such labels, and the cost of manual labeling is high and the quality is difficult to guarantee; (2) Contradictions in feature modeling: The existing difficulty features of questions mostly originate from educational and psychological theories, and there are questions where some difficulty features cannot be automatically extracted and calculated; (3) Complex experimental verification: The difficulty of mathematics application questions covers features such as question length, syntax, and reasoning, as well as features such as the concealment of conditions, and different difficulty features require appropriate automatic extraction and calculation methods. In addition, differences in feature selection lead to poor comparability of assessment results. To address these issues, this study proposes the CLT-Math difficulty feature model based on the cognitive load theory, and combines the LLM adaptive learning optimization (LLM-ALO) method to construct the Math Question Difficulty Assessment-Large Language Model (MQDA-LLMA) automatic identification framework. CLT-Math and MQDA-LLMA together form the systematic framework of Math Question Difficulty Assessment (MQDA), achieving precise identification of text features and efficient generation of mathematical expressions and answers. Experiments show that the MQDA framework can train an assessment model with an accuracy of 0.908 on Math23K using only a small number of samples (significantly reducing the labeling cost), and its generalization performance on Ape210K verifies its effectiveness, and the correlation analysis further confirms the rationality of the difficulty feature model.
