No Film At 11: the Case For the Less-Video-Is-More MOOC 87

theodp writes: In Why My MOOC is Not Built on Video, GWU's Lorena Barba explains why the Practical Numerical Methods with Python course she and colleagues put together has but one video: "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." When the cost of producing an MOOC can exceed $100,000 per course, Barba suggests educators pay heed to Donald Bligh's 1971 observation that "dazzling presentations do not necessarily result in learning." So what would Barba do? "We designed the central learning experience [of #NumericalMOOC] around a set of IPython Notebooks," she explains, "and meaningful yet achievable mini-projects for students. I guarantee learning results to any student that fully engages with these!"

    On YouTube that is pretty good... And I guarantee you that it didn't cost a hundred grand to make... You just need a camera - and a $200 Canon works great for this - and a good presenter. Guess what: good teachers usually make good presenters, and since you are already paying them to do that, that solves that problem. If you want to get really fancy, you can even spring for an external mic to clip onto the shirt they are wearing...

      The other students are the worst part of MOOCs. I've taken a number of them, and any sort of discussion forum that's offered quickly becomes a place where people from developing nations beg for special treatment. They want sumbission deadlines (every single one of them!) extended because of obscure "religious days of significance". They want exams to be optional. They demand their certificates/diplomas, before the course has ended (or sometimes before it even has begun!) and without fulfilling any of the re

        Hah. I have seen a bit of what you mean and I cringed myself. I am from a developing country (and studied in the West). Its just that the educational culture is a bit different over here. Students can get rather needy. Project work expectations are pretty low here (unlilke test performance) and they might be having a harder time to adjust. Its probably not a bad idea to have regional realms of some sort, so that students of similar cultures can participate, without stepping on other's toes.

    • This. The class I'm taking right now has videos that consist entirely (except for the intro) of the professor writing on the screen with a Wacom tablet. It's exactly like watching a lecture, except the whiteboard is a computer. By the way, I've previously taken an in-person class taught by the same guy [when I was an undergrad], so when I say it's the same I know what I'm talking about.

      The cost of producing a large amount of well-thought out, cohesive, modular, high-visual-quality video is in the labor, not the cost of the tech. What the professor is saying is that she doesn't have the time to write 200 hours of script (or even write out 200 hours worth of detailed notes), record the 200 hours (which'll take more than that to record - no-one can do 200 hours of high-quality video on the first take), go back and edit stuff (even just cutting out uhms & ahs takes long than you think - step 1 will be to re-watch the 200 hours of video to find them :) ), etc, etc.

      The $100,000 figure struck me as being weird, as well, but the professor's point is that producing 10 hours of video for each of 20 lessons in addition to all the other course materials is way, way too much to just demand that someone do.

      Besides, for stuff like this you mostly want a good book anyways. Something that you can read a short paragraph of, stop and think about for a bit, come back and re-read in order to make sure that you got it, read another paragraph the same way, maybe work through a problem or two. Videos of this would be nice, but they're window-dressing around the main event.

    • FTA: "Their recommendations to make videos better are sound (keep them short, informal, etc.), but the overall emphasis is too much on the instruction, and too little on the student—which is where learning really happens."

      It doesn't matter how good your videos look if the teacher is the one doing all the interesting work. Shift the load to the students in creative ways; they'll do the learning.

    I usually have a basic view of the MOOC topic ; at least the textbook allows me to skim it and dig deeper on the points that I'm interested in.

      I have never been able to stand more than 5 minutes of a MOOC video before telling myself 'OK, I'll find a proper textbook.'.

      You take the words right out of my mouth. There are many subjects that are not well suited to a video presentation; in fact, in my view there are very few subjects that benefit much from combining graphics, talk and soundtrack. Perhaps if you can't appreciate a mathematical subject as it is presented in its dry text form, then it isn't something you are likely to ever understand - the beauty lies in the insight it provides, 'wow factor' should be irrelevant.

      I think one of the problems with the video format is that it entices you into being passive; when you read proof in a book, you get stuck from time to time because there are things you don't understand, so you look up the things you don't understand etc, but in a video you are carried on without understanding, and although it is easy enough to stop and rewind, you tend not to because you are passively watching a video. Also, studies have shown that people tend to remember and understand less of presentations involving graphics, text and speaking, because the three forms crowd each other out.

        I dunno. I find animations of mathematical concepts to be quite effective in communicating the intuition behind them, much better than text.

        Perhaps, you just haven't seen good use of multimedia.

        > I think one of the problems with the video format is that it entices you into being passive

        I prefer videos over lectures. The reason is that I can pause them, replay them, for technical stuff, try things out.

        You might say: Well, you can do that with a book. For me, the lecture uses a more approachable language than the more formal format of the book (good for further exploration and lookups). A video demonstration is just more compact and more effective because it is multi-modal, than the full description in text.

        > because the three forms crowd each other out.

        In a well-done presentation, they are complementary... multi-modal.

        • For me, the lecture uses a more approachable language than the more formal format of the book (good for further exploration and lookups).

          Yup, and the reason that the lecture survives to this day is because people speak more naturally and use a lot more supportive redundancy. Natural redundancy tends to be edited out of books on the erroneous grounds of being needless repetition. Natural pacing is lost too, and the text becomes too dense.

          A video demonstration is just more compact and more effective because it is multi-modal, than the full description in text.

          > because the three forms crowd each other out.

          A video has the potential to be more effective because it is multimodal, but it also has the potential to do more harm than good, which brings us back to the thrust of the article -- doing video properly take

              We're clearly coming from different places. I studied for a degree and a half with the Open University in the UK, and their production qualities were top class. The other notable thing about the OU was how little of the material was actually in video form -- typically you'd get 6 books, 4 tapes/CDs and 1 VHS tape/DVD for each course. The video was designed with very specific points in mind, and a lot of it would be interviews. Most of the core learning material was in the books.

              > which brings us back to the thrust of the article -- doing video properly takes more time than it's worth

              We have an article because these lecturers are the exception (IPython Notebooks are quite good teaching tools though). If I wanted a simple presentation with no expectation of effort on media, I'd normally just go download some course lectures from iTunesU.

              A good presentation does not need a whole lot of effort. A screen cast format is not bad at all. It can involve slides, live code building, refer to web resources, screen drawing etc. That's pretty multi-modal and does not need a complex set up.

          Perhaps, you just haven't seen good use of multimedia.

          The article talks about videos, a small subset of multimedia, and the same can be said about animations. Good use of multimedia IMO tends to be when you insert illustrations into a mainly textual context; these illustrations can themselves be animations, video clips or soundbites. The reason this works is that you are still the one that does the work by reading the text, and the illustrations serve to support the meaning of the text; but if the whole thing was produced as a video, you would in a sense outso

      Depends. I've taken quite a few via coursera, and that experience you describe, I've had it with some courses, but not others. Odersky's classes in Scala or Andrew Ng's courses in machine learning have been very nice, and I don't feel like I'm missing anything I could do with a proper text book.

      After getting burned on a couple of online courses, I discovered the affordable and approachable Dover books on mathematics and computing. They seem to fit my attention span and learning style better, where I might have to spend a lot of time thinking about a short passage or an equation to understand what's important about it. They're also easier to read when I'm on a plane or at the gym.

    Reminds me of Pascal's quote of not having the time to write a shorter letter.

    As a some-time presenter myself, and having the typical introverted personality (including slow speech due to all the thought processes going on to calculate the right way to say something), I have found that it takes quite a while to prepare a good presentation (non-boring and engaging, let alone one that the audience can learn something from). I would say at least 8 hours for a 40-minute presentation, but that is after some experience already. Longer gives me more time to prepare better.

    I have seen quite a few tutorials and presentations where it seems the presenter hasn't spent much time planning the presentation through. First run through gets recorded and uploaded without too much editing either. To the point that I only watch a video to learn something as a last resort.

    Other problem is of course in areas with buggy network connectivity, or very basic connectivity like much of the third world, video is all but impossible to use.

  • How the hell is it costing $100,000 per course? Most coursera courses are just some guy talking to a webcam or a fixed camera.

So unless the check boxes on the quizzes cost $200 each something is fishy with this number.
