The participants of #NumericalMOOC will have noticed that we made only one video for the course. I thought that maybe I would do a handful more. But in the end I didn’t and I don’t think it matters too much.
Why didn’t we have more video? The short answer is budget and time: making good-quality videos is expensive & making simple yet effective educational videos is time consuming, if not necessarily costly. #NumericalMOOC was created on-the-fly, with little budget. But here’s my point: expensive, high-production-value videos are not necessary to achieve a quality learning experience.
The fixation with videos in MOOCs, online courses and blended learning is worrisome. At the edX Global Forum (November 2014), it was often mentioned that producing a MOOC is a high-cost operation, with an estimated average expense of $100,000 per course. This is probably a somewhat overindulgent price for appearance, rather than substance. There is no evidence justifying the “production value” from a learning perspective. In fact, as far back as 1971, Donald Bligh concluded that “there is not much difference in the effectiveness of methods to present information.”  In this sense, a video—however nicely produced—is not better than a lecture.
