基于强化学习的教育推荐系统方法:为学习者技能提升优化的上下文性汤普森采样

A Bandit-Based Approach to Educational Recommender Systems: Contextual Thompson Sampling for Learner Skill Gain Optimization

Lukas De Kerpel, Arthur Thuy, Dries F. Benoit

AI总结:

本文提出基于上下文性汤普森采样的方法,通过优化学习者技能提升来生成个性化练习序列,有效适应不同学习者需求。

摘要:

近年来,运筹学(OR)、管理科学(MS)和分析领域中的教学实践越来越倾向于数字化环境,在这些环境中,大量且多样化的学习者群体使得为个体提供适应性练习变得困难。本文介绍了一种方法,通过在每一步选择最可能促进学习者对目标技能理解的练习,生成个性化的练习序列。该方法利用有关学习者及其过去表现的信息来指导这些选择,并将学习进度测量为每次练习前后估计技能水平的变化。使用在线数学辅导平台的数据,我们发现该方法推荐与更大技能提升相关的练习,并能有效适应不同学习者之间的差异。从教学角度来看,该框架实现了大规模的个性化练习,突显了具有持续强学习价值的练习,并帮助教师识别可能需要额外支持的学习者。

英文摘要:

In recent years, instructional practices in Operations Research (OR), Management Science (MS), and Analytics have increasingly shifted toward digital environments, where large and diverse groups of learners make it difficult to provide practice that adapts to individual needs. This paper introduces a method that generates personalized sequences of exercises by selecting, at each step, the exercise most likely to advance a learner's understanding of a targeted skill. The method uses information about the learner and their past performance to guide these choices, and learning progress is measured as the change in estimated skill level before and after each exercise. Using data from an online mathematics tutoring platform, we find that the approach recommends exercises associated with greater skill improvement and adapts effectively to differences across learners. From an instructional perspective, the framework enables personalized practice at scale, highlights exercises with consistently strong learning value, and helps instructors identify learners who may benefit from additional support.
