I agree with the author's sentiment 100%. As others have stated, the reason that video is worse than text for learning is because A. The rate at which you can read is faster than you can listen B. Video technology is often a hassle when you need to skip around. C. It's cheaper to write and revise text than video. D. Videos consume large amounts of data. But I'm going to add another point. E. Lecturers most often don'…

> My ideal alternative would be to remove lectures entirely and to have interactive labs where teachers and TAs help students complete assignments based on assigned readings. The instructor for the course would be responsible for overseeing the teaching assistants and preparing the course outline. The TAs would help guide the students in completing the assignments or mini projects. Then a couple of time a semester th…

I'm in a class that's doing it right now. There are problems.

Often nobody knows what's going on. You can argue that confusion is good, but it's not fun and it feels wrong. You can argue that class should be challenging and active, but this method led to a minor student revolt.

Discrimination and prejudice happen. Women are underrepresented (with respect to the ratio in the class) in the conversations that happen.

We haven't figured out the right incentive structure to make people actually do the readings yet. Sometimes people don't do them.

Personally, I love this new method. It has problems on the scale of a 60ish person class in a technical subject (nonlinear dynamics). When we're working in small groups, that helps, but whenever we try to do something as a class it devolves into an impromptu lecture (most of the time by a student).

If we want to learn this way we need to know how to scale it. It seems drastically more effective, and I think that college would be so much better if this method was normal.

Simply: The average person can read at ~300 words per minute, and listen at ~150 words per minute. I'm not a big fan of video as a tool for conveying information in general. Not only can I read faster than I can listen, but I can skim and skip around as well. There are situations where video is the best way to impart certain information, but those seem to be the rare cases. I hate it when websites make me sit through…

I recently picked up a video series on Udemy with a 90% off coupon I found, and this is my exact problem. If I'm following along, I have to pause and rewind the video so often, and other times I'm flipping through reddit because he's dragging on about something or having technical difficulties while recording. Every time I need to rewind the video, it buffers for several seconds, or sometimes freezes and needs me to…

While I agree with you generally on all the reasons video's worse than text, _some_ of this is addressable with an offline video player. This is why I download virtually _everything_ I watch (desktop) via youtube-dl (it's pretty much a generic video download tool) and play it in mplayer or Xine.

In theory, VLC allows queuing of online content for playback, though in practice it's flaky enough that it crashes, loses the playlist, and/or gets confused during playback. I much prefer mplayer as a general rule.

Agreed, I would be more inclined to watch videos if they were highly edited. If you want to watch a MOOC on linear algebra the videos you will find are little more than a camcorder stuck in the corner of a classroom and dumped online. For a topic that really doesn't change decade after decade at some point someone is going to come along and produce a highly edited video that contains all of the key points, presented…

The best videos are both highly edited and extremely well scripted. Some time back there was a bit posted by a university lecturer (I want to say Harvard or Yale or similar) who described his process for preparing a lecture. It's about 10:1 prep time vs. lecture time, including multiple rehersals.

Once you've got a given lecture prepared, it's easier to edit and modify it. But getting there is the hard part.

Well said. Where's the video version of Wikipedia? Hacker news/reddit?

As a teaching tool, video doesn't lend itself to iterative refinement or discussion. It's an excellent audiovisual experience, but also a bet that the content is best delivered in a read-only format. (Practically, you can't update a video, only redo it -- presumably at full cost.)

I see video as a supplement to lesson formats that can be improved over time (text, or whatever medium comes next).

There are a lot of bloggers (John Sonmez is the most notable), who I have stopped following because they have shifted to video. I really don't have the time to watch a video, when I can read the same content in text form 2-3x faster, and do a Ctrl-F to find any terms of interest later when I want to review the content. It's a singularly inappropriate form of communication for technical subjects.

I imagine it has to hurt their Google rankings as well, especially when they don't include a transcript.

In my experience, both with self-study and at university, the best way to gain and retain knowledge is by working problems. To do this you need: demonstrations of the concepts, problems, hints and solutions. Hints and solutions can be time consuming to obtain at university (office hours) and might be impossible if you can't find instructor manuals for self-study. Khan Academy makes the most sense to me. You work the…

Oddly enough, I found this to be the case, even in my humanities courses. I learned more about a subject by having to write about it, than from merely reading or memorizing for an exam.

I've been watching the SICP videos this weekend with the goal of making it all the way through this time (I tried watching them about a year and a half ago after taking my first programming MOOC).

What struck me this time was how much the emphasis is on practical software engineering rather than Lisp. That's what Ableson is so intensely passionate about in the video, not the theory. And so picking up the book and looking at the parallel text, I reread it in a whole new light. It was like rereading Eco's Name of the Rose after 25 years and not as the piece of pop fiction I thought it was the first time.

Which brings me to my point that video is just another communication channel. It conveys particular information efficiently and other information less efficiently. Text is no different. Without the video I would never have picked up that SICP and Code Complete have many similarities in subject matter and one just starts with a clean slate and the other in the messy middle.

Video does not need to be fancy to be effective. See Jeffery Ullman's Finite Automata on Coursera. It's PowerPoint and a small talking head and a red pen: And it's better than reading the book he wrote with Who because though dense, it's an order of magnitude less dense than the text.

On the other hand, University of Phoenix operated its online courses with NNTP and was reasonably interactive though asynchronous. It's a matter of curriculum development I suppose. Dan Grossman at University of Washington compares developing a MOOC to writing a textbook and that probably captures the domain of possibilities.

The video poison is spreading to software documentation too. I can't imagine a bigger waste of time than watching someone type code or work on a command line, yet I've gotten the request many times. For GUIs I can somewhat sympathize, especially if the software changes the layout with every release (I'm looking at you, Blender), and it really does take 1000 words to describe where to click. But typed, word-oriented communication does not benefit from videos. And unless you're Vi Hart, teaching mathematics probably isn't going to benefit from an all-video presentation either. So, kudos to the author.
