Abstract

Abstract: With the continuous advancement of education digitalization, intelligent education has developed rapidly. As a core research task in the field of intelligent education, Knowledge Tracing (KT) aims to capture students' mastery of knowledge concepts based on their historical learning data to provide personalized learning paths and resources to meet the objectives of Artificial Intelligence (AI)-assisted education. Traditional KT methods primarily rely mainly on Bayesian and logic models, which have good scientific explanatory properties but exhibit limited performance when processing massive amounts of educational data. Because of its excellent feature extraction ability and performance, deep learning technology is more suitable than traditional KT methods for capturing learners' knowledge status from massive data. Therefore, a comprehensive review of research on deep learning-based KT in the field of intelligent education is conducted. First, the relevant concepts, research backgrounds, and current development status of KT in intelligent education scenarios are introduced. The KT methods based on deep learning in recent years are then analyzed and divided into four categories: Recurrent Neural Network (RNN), self-attention network, memory-enhancing neural network, and Graph Neural Network (GNN). The basic ideas and algorithm processes of these four classical and mainstream methods are systematically classified and sorted in terms of learner and exercise characteristics. Subsequently, the public education datasets currently available to researchers are introduced, and the performance of different methods on these datasets is compared. Finally, this paper summarizes deep learning KT in intelligent education and discusses possible future research directions in this field.

Key words: intelligent education, deep learning, digitization of education, Knowledge Tracing (KT), Graph Neural Network (GNN)

摘要： 随着教育数字化的不断推进,智能教育得到了快速发展。知识追踪作为智能教育领域的核心研究任务之一,旨在根据学生的历史学习数据捕获其对知识概念的掌握情况,从而提供个性化的学习路径和资源,实现人工智能(AI)辅助教育的目标。传统的知识追踪方法主要依赖于贝叶斯模型和逻辑模型,尽管具有良好的科学解释性,但在处理海量的教育数据时性能受限。深度学习技术凭借出色的特征提取能力和优异的性能优势,尤其适用于从海量数据中捕获学习者的知识状态,因此本文对智能教育领域的深度学习知识追踪研究进行了全面综述。首先,介绍了智能教育场景中知识追踪的相关概念、研究背景和发展现状。接着,分析近年来基于深度学习的知识追踪方法,将其分为基于循环神经网络(RNN)、自注意力网络、记忆增强神经网络和图神经网络(GNN)4类,并从学习者和习题特征的角度对这4类经典和主流方法的基本思路和算法流程进行归类整理。然后,介绍了当前可供研究者使用的公开教育数据集,并比较了不同方法在这些数据集上的性能。最后,对面向智能教育的深度学习知识追踪做出了总结并探讨了该领域未来可能的研究方向。
