YouTube Fridays将一小部分课堂时间用于学生选择的与课程主题相关的视频，例如热力学。然后学生们根据视频中的事件写并解决一个类似家庭作业的问题。最近的三个试点项目涉及300多名学生，他们开发了一个视频和问题数据库，以强化能量平衡和相行为等重要的课堂概念。本文介绍了二年级工程热力学课程和二年级材料与能量平衡课程中的一组例题和视频。学生评估发现，绝大多数（79%）的学生通过参加“YouTube星期五”活动，在将现实世界的现象与热力学联系起来方面感觉更好。总的来说，YouTube Fridays是一个由学生主导的活动，提供解决开放式课程相关问题的练习。
YouTube Fridays devotes a small fraction of class time to student-selected videos related to the course topic, e.g., thermodynamics. The students then write and solve a homework-like problem based on the events in the video. Three recent pilots involving over 300 students have developed a database of videos and questions that reinforce important class concepts like energy balances and phase behavior. A set of example problems and videos are presented from a sophomore level engineering thermodynamics course and a sophomore level material and energy balances course. Student evaluations found a vast majority (79%) of the students felt better at relating real world phenomena to thermodynamics from participating in YouTube Fridays. Overall, YouTube Fridays is a student led activity that provides practice of problem solving on open-ended, course related questions.
