📝 摘要(中文)
个性化编程辅导,如练习推荐,可以提高学习者的效率、动机和成果,这在现代数字教育中愈发重要。然而,缺乏足够且高质量的编程数据,以及线下评估与真实学习之间的不匹配,阻碍了此类系统的实际部署。为了解决这一挑战,许多方法尝试模拟学习者的实践数据,但往往忽视了编程学习的细粒度和迭代特性,导致缺乏可解释性和细致性。为填补这一空白,本文提出了一种基于大语言模型的智能代理——CoderAgent,旨在以细粒度的方式模拟学生的编程过程,而无需依赖真实数据。我们设计了与人类认知架构相一致的CoderAgent结构,并引入了编程思维树(PTOT),将过程分解为四个步骤:为什么、如何、在哪里和什么。实验评估表明,CoderAgent提供了对学习轨迹的可解释性洞察,并实现了准确的模拟,为个性化编程教育铺平了道路。

📄 摘要(原文)
Personalized programming tutoring, such as exercise recommendation, can enhance learners' efficiency, motivation, and outcomes, which is increasingly important in modern digital education. However, the lack of sufficient and high-quality programming data, combined with the mismatch between offline evaluation and real-world learning, hinders the practical deployment of such systems. To address this challenge, many approaches attempt to simulate learner practice data, yet they often overlook the fine-grained, iterative nature of programming learning, resulting in a lack of interpretability and granularity. To fill this gap, we propose a LLM-based agent, CoderAgent, to simulate students' programming processes in a fine-grained manner without relying on real data. Specifically, we equip each human learner with an intelligent agent, the core of which lies in capturing the cognitive states of the human programming practice process. Inspired by ACT-R, a cognitive architecture framework, we design the structure of CoderAgent to align with human cognitive architecture by focusing on the mastery of programming knowledge and the application of coding ability. Recognizing the inherent patterns in multi-layered cognitive reasoning, we introduce the Programming Tree of Thought (PTOT), which breaks down the process into four steps: why, how, where, and what. This approach enables a detailed analysis of iterative problem-solving strategies. Finally, experimental evaluations on real-world datasets demonstrate that CoderAgent provides interpretable insights into learning trajectories and achieves accurate simulations, paving the way for personalized programming education.
