Perspective on Developing Educational Lecture Videos for Power Electronics Courses

Abstract

Online learning resources are gaining wider attention, especially as flipped-learning and massive open online courses are becoming more popular. Various types of lecture videos were developed for an introductory power electronics course, implemented based on the flipped learning educational model. The approach and pedagogy is outlined for these flipped-learning courses and video lecture development. Feedback and responses from students is used to evaluate and discuss the effect of video quality on student learning and explore effective video qualities. Generally, self-made and professional videos both show similar learning effectiveness. Student feedback indicates that many students prefer the self-made videos over the professional videos, which takes significantly less prep time for the instructor. Students in the classes generally reacted positively to flipped learning using online lecture videos and expressed a demand for more educational video content on power electronics.
