📝 摘要(中文)
有效的个性化AI辅助学习需要能够生成准确的学习者特定教育材料并动态适应不同学习者的系统。然而,现有教育代理主要集中于讲座内容自动化和模拟,往往无法针对个体学习者建模多模态和具身的教学方法。为此,我们提出LectūraAgents——一个通过端到端适应性具身教学实现个性化学习的多代理框架。LectūraAgents模拟教授与学生的关系,由ProfessorAgent领导一组专门的下属代理,进行研究、规划、审查和适应学习者需求的讲座内容的具身传递。该框架的三大贡献包括:1)用于端到端个性化学习的分层多代理架构;2)适应性具身教学机制,ProfessorAgent在教学环境中执行可见且具有教育动机的教学动作;3)教学动作-语言对齐(TASA)算法,通过显著性启发式和时间语义分割生成与学习者特征一致的连贯教学动作序列。实验结果显示LectūraAgents在讲座内容质量、具身教学质量、评估和个性化方面均优于现有方法。
🔬 方法详解
问题定义:本论文旨在解决现有教育代理在个性化学习和具身教学方面的不足,尤其是在动态适应学习者需求方面的挑战。
核心思路:LectūraAgents框架通过多代理系统模拟教授与学生的互动,提供个性化的学习体验,强调适应性和具身教学的重要性。
技术框架:该框架包括一个ProfessorAgent和多个专门的下属代理,负责研究、规划和传递适应学习者需求的讲座内容,形成一个分层的多代理架构。
关键创新:最重要的创新在于引入了适应性具身教学机制和TASA算法,使得教学动作与学习者特征之间能够实现有效对齐,提升了教学的连贯性和针对性。
关键设计:在设计中,ProfessorAgent执行可见的教学动作(如手写、标记等),并通过显著性启发式和时间语义分割生成教学动作序列,确保教学内容与学习者的需求相匹配。

📄 摘要(原文)
Effective personalized AI-assisted learning demands systems that can not only generate accurate learner-specific educational materials, but also dynamically adapt their instruction to diverse learners. However, existing educational agents have primarily focused on lecture content automation and simulations, which often fall short of modelling multimodal and embodied instructional methods tailored for the individual learner. To this end, we propose LectūraAgents - a multi-agent framework that enables personalized learning through end-to-end adaptive embodied teaching. At its core, LectūraAgents mirrors a professor-student relationship, in which a ProfessorAgent leads a collaborative team of specialized subordinate agents through research, planning, review, and embodied delivery of lecture contents that adapt to a learner's needs. The framework offers three main contributions: (1) a hierarchical multi-agent architecture for end-to-end personalized learning; (2) an adaptive embodied teaching mechanism, wherein the ProfessorAgent executes visible and pedagogically motivated teaching actions (e.g., handwrite, highlight, underline, etc.) over contents in a teaching environment; and (3) a Teaching Action-Speech Alignment (TASA) algorithm that employs salience-based heuristics and temporal semantic segmentation to generate coherent teaching action sequences aligned with learner profiles. We evaluate LectūraAgents on diverse courses at high school, undergraduate, and graduate levels using sample-specific rubric-based analysis; with generated lecture materials and teaching actions assessed and validated by expert educators. Experimental results show consistent gains in lecture content quality, embodied teaching quality, assessment, and personalization over existing approaches, positioning LectūraAgents as a pedagogically well-grounded framework for personalized learning at scale.
