2020年的COVID-19大流行极大地加速了许多学院和大学在线学习和教学的采用。视频作为在线教育的重要组成部分，很大程度上影响着学生的学习体验。尽管已经报道了许多设计教育视频的指南，但显示视频长度对学分课程中学生学业成绩影响的定量数据仍然有限，特别是对于在线翻转大学工程课程。大流行的强制封锁为解决这一研究空白提供了合适的环境。在本文中，我们提出了第一步来研究在这种情况下短视频对学生学业成绩的影响。我们的结果表明，与长视频组相比，短视频可以极大地提高学生的视频观看时间 24.7%，期末考试成绩提高 9.0%。定量李克特问卷还表明学生对短视频的偏好超过长视频。我们相信这项研究对未来在线翻转工程课程的课程设计具有重要意义。
The 2020 COVID-19 pandemic has greatly accelerated the adoption of online learning and teaching in many colleges and universities. Video, as a key integral part of online education, largely influences student learning experiences. Though many guidelines on designing educational videos have been reported, the quantitative data showing the impacts of video length on students’ academic performance in a credit-bearing course is limited, particularly for an online-flipped college engineering course. The forced pandemic lockdown enables a suitable environment to address this research gap. In this paper, we present the first step to examine the impact of short videos on students’ academic performance in such circumstances. Our results indicate that short videos can greatly improve student engagement by 24.7% in terms of video viewing time, and the final exam score by 9.0%, both compared to the long-video group. The quantitative Likert questionnaire also indicates students’ preference for short videos over long videos. We believe this study has important implications for course design for future online-flipped engineering courses.
