中文摘要 AI 辅助
我们提出了一项互动式课堂活动，旨在解决入门贝叶斯统计教学中的一个核心挑战：如何将主观知识和可用信息形式化为先验分布，并随后用经验数据对其进行更新。学生们扮演赛车队的数据分析师，通过将定性工程报告转化为先验分布、通过虚拟赛车游戏收集一手数据，并使用Beta-Binomial模型为车队策略提供信息，来评估候选轮胎。这种基于发现式的练习使小组能够直接观察到不同的先验选择和样本数据如何共同塑造后验推断。学生反馈（n=32）显示，该活动带来了高度的愉悦感、参与感和概念清晰度的提升。我们提供了实施该活动的开放获取材料，并附有将其改编至其他教学情境的建议。
英文摘要
We present an interactive classroom activity designed to address a central challenge in teaching introductory Bayesian statistics: how to formalize subjective knowledge and available information into prior distributions and then update them with empirical data. Role-playing as data analysts for a racing team, students evaluate candidate tires by converting qualitative engineering reports into prior distributions, collecting primary data via a virtual racing game, and using a Beta-Binomial model to inform team strategy. This discovery-based exercise allows small groups to observe directly how different prior choices and sample data jointly shape posterior inference. Student feedback ($n=32$) highlights high enjoyment, engagement and improved conceptual clarity. Open-access materials to implement the activity are provided, alongside recommendations for adapting it to other teaching contexts.
