使用教学视频-无论是作为补充内容或在翻转教室-已成为越来越受欢迎的学生和教师在高等教育CS课程。然而，制作或找到合适的视频可能是昂贵和耗时的。这份经验报告描述了一种新颖的、成本相对较低的方法来创建定制的视频资源，只需要很少的教师时间。这种方法利用广泛使用的屏幕捕获和播客技术，从全长现场讲座片段中制作一套2-5分钟的“播客亮点”视频。播客重点将讲座的概念提炼成简短的片段，补充注释有助于进一步说明这些概念。本科生只需少量的教师监督就可以快速创建播客亮点。我们为四门本科CS课程创建了播客集锦视频。在对其中两个班级的试点研究中，许多学生经常使用重点视频，并称赞它们在预览和复习课程概念方面的有用性。本报告介绍了播客亮点制作过程，学生的反应和使用播客亮点视频，以及创建和部署这些定制的教育视频的最佳实践。
Using instructional videos - either as supplemental content or in a flipped classroom - has become increasingly popular among students and instructors in higher education CS courses. However, producing or finding appropriate videos can be expensive and time-consuming. This experience report describes a novel, relatively low-cost approach to creating customized video resources that requires very little instructor time. This approach leverages widely available screen capture and podcasting technologies to produce a suite of 2-5 minute "podcast highlights" videos from full-length live lecture footage. Podcast highlights distill lecture concepts into short segments, and supplementary annotations help illustrate these concepts further. Podcast highlights can be created quickly by undergraduates with just a small amount of instructor supervision. We created podcast highlights videos for four undergraduate CS courses. In a pilot study with two of these classes, many students used the highlights videos regularly and praised their usefulness for both previewing and reviewing class concepts. This report presents the podcast highlights production process, student reaction to and use of podcast highlights videos, and best practices for creation and deployment of these customized educational videos.
