(Well, technically you can, but it\u2019s a bad idea.) A well-established guideline related to students\u2019 attention span says that for<em>\u00a0online lecture clips and screencasts, shorter is better and about\u00a0six minutes is a good target.<\/em><\/p>\n<p>Marketing gurus at Wistia Blog have analyzed 564,710 videos with more than 1.3 billion plays and have found that (as you would expect) the longer the video, the less likely people are to complete it. Very short videos of less than two minutes hold a viewer\u2019s attention best, but videos that short are generally not that useful for covering the amount of content we want to present. You can see the data <a href=\"https:\/\/wistia.com\/blog\/optimal-video-length\" target=\"_blank\" rel=\"noopener\">here<\/a>.<\/p>\n<p>Okay, I hear you say\u2014that\u2019s well and good for marketing. Surely, I can use longer videos than THAT when I\u2019m teaching college students.<\/p>\n<p>Well, again, let\u2019s look at the evidence. In a 2014 study, some MIT professors studied viewer persistence data from 6.9 million video sessions in four EdX MOOC offerings (<a href=\"http:\/\/groups.csail.mit.edu\/uid\/other-pubs\/las2014-pguo-engagement.pdf\" target=\"_blank\" rel=\"noopener\">Guo, et. al, 2014<\/a>). They found that video length was \u201cby far the most significant indicator of engagement\u201d as measured by the length of time students watched the video and whether they attempted embedded assessment questions. Median engagement time was six minutes regardless of video length, leading to the authors\u2019 recommendation that <em>videos should be edited into short chunks of less than six minutes in length<\/em>.<\/p>\n<p>So what should you do in your short videos? The MIT folks have answers for that one, too. It turns out that tutorials in which you do step-by-step problem solving (think Khan Academy) are more effective than PowerPoint slides. (Then again, what isn\u2019t, except for showing pictures, diagrams, and charts with minimal verbiage?) Filming in a more informal setting where you can make eye contact, such as with a laptop webcam in your office, may be more effective than a fancy professional studio production. Finally, it works better to plan these videos specifically for the online format instead of just videotaping a class and hoping for natural stopping points.<\/p>\n<p>The next big question, of course, is how do I\u00a0get students to watch the videos and truly engage with the material? There are answers aplenty for that question, which we\u2019ll take up in a future blog. In the meantime, whatever you do, make those online videos short!<\/p>\n<p>Guo, P.J., Kim, J., &amp; Rubin, R.
