Instructional Videos in an Online Engineering Economics CourseThe use of video lectures is a common method of delivering course content in online learningenvironments. Over time, our understanding of what makes an effective online video has evolvedwith advances in educational research and technology. In the past decade, free online videoservices such as YouTube have allowed widespread dissemination of instructional videos.Prevalence of high-quality instruction produced by organizations such as Kahn Academy hasadvanced our knowledge of effective video techniques and increased our students’ expectations.Recent research has explored the elements of lecture videos and presentation styles that eithercontribute to, or detract from, student engagement. This paper explores one instructor’sexperience with teaching an online course in engineering economics multiple times, the originaldevelopment of lecture videos and the subsequent editing and rework of those videos. Untilrecently, the effectiveness of the course videos was judged primarily from student feedback incourse evaluations. However, the most recent version of our institution’s learning managementsystem allows collection of detailed student viewing data on the videos, including number ofviews, average view time and drop-off rates. Correlation between video viewing habits andstudent performance is explored and recommendations and lessons learned are provided.
