AI 中文总结
本研究针对学生提交信息沟通失效的教学问题，设计了教育游戏WDYM，可提升相关意识与反思，但对提交信息编写实践的改善证据有限，仅适用于研究场景。
AI 中文摘要
本文报告了一项基于本地需求的混合方法案例研究，旨在解决软件工程教师持有的与教学相关的疑虑：学生编写的提交信息常常无法发挥其预期的沟通作用。为了凭经验检验这一疑虑，我们使用已确立的提交信息质量分类法的部分复制品，分析了学生和工业案例研究项目中的提交信息。结果证实，两种场景中均反复出现沟通和质量问题，印证了教师最初的担忧。受此发现的启发，我们设计了What Do You Mean?（WDYM），这是一种轻量级、基于角色的教育游戏，旨在在大学课程的限制范围内揭示并解决提交信息的沟通故障。对游戏玩法观察和参与者调查的分析显示，WDYM在提高对提交信息沟通问题的认识并促进相关反思方面是有效的，但它仅提供有限的证据表明提交信息编写实践能立即或持续得到改善。总体而言，本研究提出WDYM作为一种有用但并不完美的、受场景限制的干预措施，用于解决本地观察到的教学问题，不声称其在研究场景之外具有普遍适用性。
英文摘要
This paper reports on a locally motivated mixed-methods case study addressing a teaching-related suspicion held by software engineering instructors: that commit messages written by students frequently fail to serve their intended communicative role. To examine this suspicion empirically, we analyzed commit messages from student and industrial case-study projects using a partial replication of an established commit-message quality taxonomy. The results confirm that communication and quality issues occur recurrently in both contexts, substantiating the instructors' initial concern. Motivated by this finding, we devised What Do You Mean? (WDYM), a lightweight, role-based educational game intended to surface and address commit-message communication breakdowns within the constraints of university coursework. Analysis of gameplay observations and participant surveys shows that WDYM is effective in raising awareness and fostering reflection on commit-message communication issues, although it provides limited evidence of immediate or sustained improvement in commit-message writing practices. Taken together, the study presents WDYM as a useful, though imperfect, context-bound intervention for addressing a locally observed instructional problem, without claiming general applicability beyond the studied setting.
