AI 中文总结
本研究分析Stack Exchange网络中7900余万条帖子，针对计算机科学教育工作者的讨论主题建模，发现其关注IT与非IT多领域，为支持其专业与教育需求提供参考。
AI 中文摘要
Stack Exchange是一个广泛使用的问答网络，促进不同领域的知识交流。在该网络中，计算机科学教育工作者Stack Exchange（CS Educators Stack Exchange）提供了一个专门平台，供计算机科学教育工作者交流想法、寻求建议并讨论教学实践。本研究分析了79,854,463篇Stack Exchange帖子，其中包含32,187,805个问题和47,666,658个答案，特别关注由CS Educators参与者贡献的英文帖子。通过主题建模，我们识别、手动标记并分层组织了潜在的讨论主题，随后检查了它们的分布和复杂性。我们的研究结果显示，讨论模式在技术（IT）和非技术（Non-IT）领域均有演变：在IT类别中，编程和软件开发是最突出的主题，而数学、教育和人文在Non-IT类别中受到大量关注。这些结果凸显了CS教育工作者共享的广泛兴趣和专业知识，并为他们不断演变的优先事项提供了见解。我们希望这项工作有助于更好地理解CS教育工作者的知识共享实践，并为未来更好地支持他们的专业和教育需求提供信息。
英文摘要
Stack Exchange is a widely used question-and-answer network that facilitates knowledge exchange across diverse domains. Within this network, the Computer Science (CS) Educators Stack Exchange provides a dedicated platform where CS educators exchange ideas, seek advice, and discuss teaching practices. In this study, we analyzed 79,854,463 Stack Exchange posts, comprising 32,187,805 questions and 47,666,658 answers, with a particular focus on English-language posts contributed by CS Educators participants. Using topic modeling, we identified, manually labeled, and hierarchically organized the underlying discussion topics, then examined their distribution and complexity. Our findings reveal evolving discussion patterns spanning both technical (IT) and non-technical (Non-IT) domains. Within the IT category, programming and software development were the most prominent topics, whereas mathematics, education, and the humanities received substantial attention within the Non-IT category. These results highlight the broad range of interests and expertise shared by CS educators and provide insights into their evolving priorities. We hope this work contributes to a better understanding of CS educators' knowledge-sharing practices and informs future efforts to better support their professional and educational needs.
