In the realm of intelligent education, knowledge tracing (KT) has emerged as a crucial tool for enhancing educational efficiency and enabling personalized learning. Traditional KT methods primarily rely on students’ historical response data to evaluate their mastery of specific skills and forecast future performance. However, focusing solely on basic interactions, skills and response outcomes, makes it challenging to capture the complexities of real learning environments and accurately reflect students’ genuine knowledge states. To address this issue, we propose an innovative multi-feature based memory-enhanced knowledge tracing (MMKT) method. The key innovation of the MMKT model lies in the introduction of ‘memory features’ and ‘interaction features’. Memory features account for features such as the interval between repeated responses, the total number of responses, and memory interference during the overall learning process. In contrast, interaction features include response time, number of attempts, and hints. To integrate these features, we employ a self-attention mechanism coupled with a memory enhancement module and a recurrent neural network. This approach effectively uncovers variations in knowledge states while balancing the influence of global and local interactions. Our experimental results from different public datasets emphasize the benefits of the MMKT model in predicting future performance, underscoring the significance of integrating multi-feature and real-world relevant memory improvements.
