传统的以讲座为中心的课堂正在受到主动学习混合课程的挑战。在资源有限且主要是非传统学生的小型研究生课程中，探索如何使用在线技术来优化教授在课堂上的角色势在必行。然而，这方面的研究很少。在这项研究中，使用短的统计计算视频教程进行了探讨，在一个小的公共卫生计划在新墨西哥州大学的试点研究。这些视频在两个硕士水平的生物统计学课程和学生的视频感知进行了评估，使用定量调查和定性焦点小组。16名调查对象和12名焦点小组参与者的结果在两个课程中呈现。视频的观看率很高，16名受访者中有15人表示经常或总是观看视频。总体而言，对视频作为学习工具的看法是积极的，16名受访者中有14人同意视频为他们提供了优势。在我们的分析中出现了两个突出的主题：（1）视频的可用性和便利性;（2）通过提供视频促进了更深入的学习。我们的结论是，短视频教程是一个有用的学习工具，在我们的研究人群。
Traditional lecture-centered classrooms are being challenged by active learning hybrid curricula. In small graduate programs with limited resources and primarily non-traditional students, exploring how to use online technology to optimize the role of the professor in the classroom is imperative. However, very little research exists in this area. In this study, the use of short statistical computing video tutorials was explored using a pilot study in a small Public Health Program at the University of New Mexico. The videos were implemented in two Master's-level biostatistics courses and student perception of the videos was assessed using quantitative surveys and qualitative focus groups. The results from 16 survey respondents and 12 focus group participants are presented across the two courses. Viewing rates for the videos were high, with 15 out of 16 respondents reporting usually or always viewing the videos. Overall perception of the videos as a learning tool was positive, with 14 out of 16 respondents agreeing that the videos offer advantages to them. Two prominent themes emerged in our analysis: (1) the usability and convenience of the videos and (2) the deeper learning facilitated by having the videos available. We conclude that the short video tutorials were a useful learning tool in our study population.
