I have made a tiny unfinished side project for creating an e-book like format for your videos. I wrote a few myself. It was quite similar to the blog posts you are talking about, inspired by https://eater.net/quaternions webpage.

My take is that they are definitely useful, not just because of quizzes, but even for revision (I'm a student). If I want to religiously study all the material from your videos, it does help if it is in the form of a blog post, as the videos are engaging but don't help much in either retention or revision.

I think it will be definitely beneficial for people who just want to have a quick look over concept that they want to revisit or old school people like me who prefer a book type setting over tutorial and videos. Visualizations can be added to blogs too so it's a win win situation.

Also, hats off to you for such a great work _/_

I'd love more quizzes!

Yes, surprised it needs to be mentioned at this stage in the development of civilization but please write things down.

I would definitely use your written content to supplement the videos!

I've been a viewer of your content from the 1st release and many of your works on Kahn Academy. I established KRV SCIENCE INC a 501c3 scientific educational nonprofit foundation to help promote STEM education. With your permission we would like to promote you site and content as an educational free resource to all that cross our path. Please let me know if you're OK with that. The website is under construction currently.

I'll also be asking the same of Kahn Academy and many others.

Thank you for your consideration.

Hi Wiliam, I'd of course be honored if you included my site, thanks for thinking of me.

Can’t thank you enough

The written version is a huge help. I find information tends to stick a little better with reading. But video can be helpful for clarifying more complicated concepts. Having both modalities is the perfect solution.

On the topic of quizzes: I think this sample quiz feels a bit too much like a short written exam after a university course. Questions like "what does ASIC stand for?" are not that fun to me. Some of the first questions were pretty interesting, especially those questions that were not just about regurgitating things that were said in the video. It would be interesting as a bonus material, maybe following a track parallel to the video itself, like solving another problem step-by-step that relies on the same kinds of results or intuitions, but then it would have to be thought about by yourself when you are doing a video, and I do not know whether this is something you would enjoy doing (if so, I would absolutely love going thtough these quizzes). I hope that made sense.

Also, this "Think fast!" question was not really about thinking fast, which was confusing.

As for written material with a few interactive animations: YES. I do not think that these sliders are enjoyed by the devs more than the users: there is a reason a lot of people love the Explorable Explanations that Nicky Case put together (including a few that they actually made). I discovered myself learning about character recognition, something that I did not think I would enjoy reading about, as the interactive part of it was really keeping me going and making me have fun going through the whole thing.

Hi Mathias,

I'm Michael, the founder of Retainit.

Thanks very much for taking the time to write such thoughtful feedback. It's extremely helpful that you've made specific points about this quiz (e.g., the point about the ASIC question) as well as wider points about the form you'd want future quizzes to take. We're updating this quiz today based on initial feedback, and your comments will be factored into the quiz-writing process moving forward.

We're building a Discord community for feedback on quizzes before they go out to a wider audience. If you'd be interested in joining, we'd love to hear your feedback in future! (If you send your email address with the title '3B1B Discord' to michael@retainit.app, I'll add you to the community.)

Thanks again,

Michael

Yes please, It is a huge plus to have a written format as a reference, as i for one a prefer it on the go for review purposes.

Make a video about Arnoldi and Lanczos algoritms (visalizations for orthogonalization) or regularization techniques like Tikhonov. We look forward for it!
