3b1b shows us what’s possible in math pedagogy. I’m excited for the future of the space, but sad it will take so long to adopt methods like this for teaching ma

  The amount of effort to do a single 30 minute video of this sort when scaled out to a half or full year math class is significant. Another consideration is that we learn things from it because we want to learn it. We are engaged with the topic the instant we hit play because we want to watch it. Compare that with a high school or college setting where the majority of the class is taking it because they have to - not because they want to. This means that there's no initial engagement and a professor can't call out the student in the 3rd row from the back that is starting to fall asleep. This can work really well for the people who want to learn it. However, it potentially adds to people who don't want to become competent in the material falling further behind.

    I agree you can’t get around people fundamentally not being interested in the material. That being said, I still think that the power of 3b1b does should not be understated. It can cultivate interest as well!

    > The amount of effort to do a single 30 minute video of this sort when scaled out to a half or full year math class is significant. This is true if Grant is the only person doing the work, however having a well educated and scientifically engaged populace seems important enough that we (the human race) should devote a few more resources to creating high quality (and freely available) courseware for all curricula/year levels.

    I’ve had classes where I didn’t want to learn shit but I learned anyway because of videos like this. Like the explanation is so clear that as long as you don’t fall asleep you absorb it. I didn’t become interested in science and math until later in my life and I spent much of my childhood in classes where I didn’t care.

    I usually watch 3b1b without any prior “want to” or any idea what it will be about. For me it’s the format that drives interest. Although I’m from a natural-math-guy group, in a sense that I usually have no issues with understanding the material, in contrast to these “so interesting, but I understand nothing” comments below it. I always wonder why they watch it, cause it must be just a set of vector animations then.

    High school math has a standardized curriculum that doesn't change significantly - it's 100% possible to create this high quality material for the whole n years and make use of it year after year. Especially that the most important part of this is the software used to make these semi-interactive graphics (which is open-source), so a teacher can just do it their own way, incorporating animations fit for their examples - no need to pre-render a video for each day. Do a "normal" class and visualize important aspects.

  There is no royal road to geometry just like the route to Carnegie Hall is practice practice practice.

  Yes and no... Ultimately it would be impossible to come up with these greatly simplified explanations without the complexities and notation taught in the pedagogy you are dismissing. Granted though, as students, the gifted ones often already have this picture in their mind, so the intuition is obvious. So to bring those less gifted or familiar with a topic up to speed, things like this make a ton of sense.
