Topics related to energy transformation and metabolism are important parts of an undergraduate biology curriculum, but these are also topics that students traditionally struggle with. To address this, we have created a short online Interactive Video Vignette (IVV) called To Ferment or Not to Ferment: That is the Question. This IVV is designed to help students learn important ideas related to cellular respiration and metabolism. Students in various courses across four institutions were assigned the IVV as an out-of-class preinstruction homework assignment. To test the effectiveness of this IVV on student learning, we collected and analyzed data from questions embedded in the IVV, open response reflection questions, and pre- and postassessments from IVV watchers and nonwatchers. Our analysis revealed that students who completed the IVV activity interacted productively with this online tool and made significant learning gains on important topics related to cellular respiration and metabolism. This IVV is freely available via https://www.rit.edu/cos/interactive/MINT for instructors to adopt for class use.

在线互动视频小插曲，可帮助学生学习发酵和呼吸的关键概念

与能量转换和代谢相关的主题是本科生物学课程的重要组成部分，但这些也是传统上学生难以解决的主题。为了解决这个问题，我们创建了一个简短的在线交互式视频小插图（IVV），称为“发酵或不发酵：这就是问题”。该IVV旨在帮助学生学习与细胞呼吸和新陈代谢有关的重要思想。在四个机构中，各个课程的学生都被分配了IVV，作为课外课前作业。为了测试该IVV在学生学习中的有效性，我们从IVV中嵌入的问题，开放式反应反思问题以及IVV观察者和非观察者的评估前后，收集并分析了数据。我们的分析表明，完成IVV活动的学生与该在线工具进行了富有成效的互动，并在与细胞呼吸和代谢相关的重要主题上获得了重要的学习成果。该IVV可通过https://www.rit.edu/cos/interactive/MINT免费获得，以供教师采用以供课堂使用。
