一句话：对108场匿名无主持P2P编程辅导对话进行混合分析，揭示其对话动态与满意度，为可扩展同伴辅导系统设计提供依据。
许多人想学编程却缺乏传统课堂指导，而Stack Overflow、ChatGPT等在线工具可能缺乏个性或强化不良开发习惯。匿名点对点（P2P）辅导有望提供可扩展支持，但尚不清楚如何为CS教育有效设计。本文对Python Tutor平台上108场匿名、无主持的点对点CS辅导会话进行混合方法分析：新手（Learner）在共享编码环境中向志愿者（Helper）求助。研究提出基于质性证据的用户动机、对话动态与学习者满意度模型。结果显示，59%的辅导交互获得有用帮助，78%的消息低毒性，无需主持即可运转；83%的对话反映软件开发关键阶段，17%的对话建立了个人联系。作者识别了与满意度相关的行为，并讨论了对可扩展同伴辅导系统设计的启示。
Many people want to learn to program but lack access to traditional classroom instruction. Teaching these novices at scale is crucial for building a more diverse and capable software engineering workforce. While online tools like Stack Overflow and ChatGPT offer help, they can be impersonal or reinforce poor software development practices. Anonymous peer-to-peer (P2P) tutoring has the potential to be an additional place for scalable support, but we lack a firm understanding of how to best support it for CS pedagogy. We present a mixed-analysis study of n=108 anonymous, unmoderated P2P CS tutoring sessions. We analyze text-based conversations from Python Tutor, a widely-used learning platform. In this setting, novice programmers (Learners) request help from volunteer programmers (Helpers) in a shared coding environment. We present a qualitatively-backed model of user motivations, conversational dynamics, and Learner-reported satisfaction. Surprisingly, Learners often receive useful (\(59\%\) of tutoring interactions), low-toxicity (\(78\%\) of messages) help without moderation. P2P chats reflect key phases of the software development process (\(83\%\) of chats) and occasionally foster personal connection (\(17\%\) of chats). We identify behaviors linked to satisfaction and discuss implications for scalable peer tutoring system design for CS education.
