一句话：通过分析32个本科团队963条冲刺回顾陈述，揭示学生反思的内容、质量及团队差异。
该研究关注本科团队软件项目中的冲刺回顾：学生反思什么、质量如何、团队间有何差异。作者对两所北美大学四门课程中32个团队（182名学生）的963条回顾陈述进行内容分析，并按是否为停止、继续或开始某策略提供理由评估质量。结果显示，团队最常反思工作、沟通与协作；近三分之一聚焦一般工作实践，近一半聚焦软件开发生命周期具体领域，尤以 pull request、issue 和编码/测试/调试为主。仅13%的反思为策略提供理由；团队间内容与质量差异显著。作者与已有学术和工业研究比较，并讨论对软件工程教育的启示。
The retrospective, or retro, is a fundamental component of the Agile process, widely used in both software engineering courses and industry. In a retro, teams come together at the end of a sprint to reflect on their team's performance. We conducted an empirical study to explore three research questions concerning retros in undergraduate team projects: (1) What do students reflect on? (2) What is the quality of their reflections? (3) How do teams' retros vary in terms of content and quality? Our study analyzed a corpus of 963 statements documented in the retros of 32 undergraduate software teams (n = 182 students) enrolled in four software engineering courses at two North American universities. A content analysis revealed that teams reflected most often on their work, communication, and collaboration practices. Nearly a third of teams' reflections focused on their general work practices, while nearly half focused on specific areas of the software development lifecycle-most prominently, pull requests, issues, and coding/testing/debugging. An analysis of the quality of teams' retro reflections showed that only 13% provided justification for a strategy to be stopped, continued, or started. An analysis of team-by-team results indicated significant differences in teams' retro content and quality. We compare these results to previous studies of retros in academia and industry, and consider their implications for software engineering education.
