I'm a secondary math teacher. I often teach seventh to ninth graders, and I have a story I tell to all new classes about how I became a math teacher. In primary school, I was behind in math. I didn't enjoy it. I didn't like memorizing multiplication tables, etc. When I entered seventh grade, I was tested at fifth-grade level. My school didn't have traditional math instruction. It had a "reading lab" model for math, with each lesson as a one-pager with problems on the back of the page, all in a box at the front of the room. Kids took the cardboard lesson next in the curriculum to their seats, read, and worked on the practice. Once they finished, they took their work to the teacher to check. If they passed, then they did the next lesson. Forever. So it was Khan in a pre-computer age. I finished fifth grade, then sixth. Then seventh, then eighth. So in one year of seventh grade, I went from being two years behind to being a year ahead. By the end of eighth grade, I was two years ahead. Self-paced education lets kids take time when they need to, and move fast when they can. They can go from behind to ahead in a single year if they are given the chance. One more thing -- running in formation in the military is always slower than the slowest person. You might think it's as slow as the slowest, but it's even slower than that.

I’m in 9th and I’m not that great at math but I want to go into science I know that math is a major part of that. Honestly math is extremely interesting to me, but I’ve had a lot of holes in my math education because I was never really taught how to look at the big picture to retain the main ideas. I’m trying to fill in my holes from 9th grade and below this summer as well as get ahead in geometry and possibly even a little bit of algebra 2. It makes me feel so horrible when I realize I’ve forgot simple concepts that I learned so long ago but I’ve realized if I want to be good at it I really have to self study it because in school they tend to leave you behind feeling lost.

[@themysteriouspencil4766]

I entered 9th grade taking algebra 1 and, through self studying, I am now on a track to graduate with calculus 3 (now between 10th and 11th)

OMG OMG OMG Sal Khan and 3blue1brown? I lived in Latvia for two years and went to the 7/8 th grade there. But I didn't understand almost anything, cause the lessons were in Russian and Latvian. So what I did was going to school every day, and then after school I would open Khan academy and start learning online. I learnt so much there, the knowledge I got from there is the basic of my current understanding of science. It helped me SO much. Thank you Sal, thank you Khan academy, you must have changed life of millions.

Around the time Sal is talking about editing things out, I remember in his differential equations course a long time ago, in one of the modules he pauses because he hears someone coming in into his house. Sal says "I thought a critter was getting into my house, turns out it was my wife." I don't know if anyone else saw this video.

My first class on my first day of college was a multivariable Calc class and I had never been taught matrix math in school, so when the professor assumed everyone knew how to do a determinant it really threw me for a loop. I vividly remember sitting in the library afterward, frantically searching online for a good explanation of it and other matrix math concepts. I stumbled across khan academy and watched maybe an hour's worth of videos and did some practice on paper until I had a handle on it, and it really saved my skin going forward in that Calc class. I haven't watched any other khan academy content since then, but Sal's voice and tone and general demeanor have always stuck with me, and in my mind he'll always be the guy that got me through multivar

[@xValkyrie93]

Amazing conversation. Really interesting to listen to. When I was in Primary School, up to 12 yrs old, there was 12-18 kids. Only 2 teachers. The conversation about learning where its based upon the speed you actually learn really hit home because i distinctly remember going to a new school the year after, and thinking, Ive done all of this math before 1-2 years ago. For me it didnt feel like i learnt at a fast pace, but it was in comparison to others. But it allowed me to just learn with no boundaries. Really hope that the world is slowly moving towards this as I do see this being very positive.

[@MehbubulHasanAlQuvi]

Huge thanks to Khan Academy and you for the Multivariable Calculus videos. I enjoyed every single video and learned a lot from them. The extraordinary visualizations helped me learn in a way I could never imagine!.

I was fortunate enough to go to a school in the UK which was setup by a businessman and funded by industry which was an incredible experience, kudos to parents who do have the open mind required to experiment with new styles, in the future many of the people you've taught will look back warmly on the experiences you've provided them with.

I really resonate with the final statement in the podcast. Too many educational videos fail due to not having enough silence.

[@artako]

On the last podcast Grant mentioned that before writing the script for a video he would hop on to a Zoom call with a person and teach that topic to figure out the structure of the script. Imagine being the person on the other side of the call. Sounds like so much fun! Great podcast Grant!

Gosh. These podcasts are incredible. It was great learning more about Mastery-based learning and it is more suitable for student's learning journeys than traditional learning.

[@sirpikapika1129]

Listening to this I realize that I would be amazing at teaching. I have ASD and I constantly felt confused about so many things growing up. I remember that feeling of helplessness, exhaustion, and embarrassment very vividly. My personal ASD features hyper empathy, and combined with my experiences I can model people’s knowledge and headspace very well. On top of that, I make an effort to always assume that nobody knows about something rather than assuming everyone knows about it. It feels so alienating to have someone casually talk about stuff that makes no sense to you, I will gladly take the minor annoyance of having something re-explained to you in order to avoid that alienation.

Yay!!..the Soh Ka Toa, dude! Congrats to both of you and to Sal, you have probably been the most influential person in the modern age! and regarding the idea of actual communication across the media membrane, editing videos takes away the spontaneity of it. Sal's self correcting comments in the middle of a video adds to the value of the communication and his willingness to rerun the tape if you didn't get the content. I have spent many hours issues of differential calculus to understand Maxwell's equation and there is a beauty in the message that ta carried to people everywhere, including S-E Asia and Africa. Fantastic work!!

[@JoelRosenfeld]

One thing I'd like to comment on is the "checking ID" in university classrooms. We absolutely did that when I was a graduate student TA'ing for Calculus 1. When I was a graduate student, we proctored mass exams with about 150 students per lecture hall, and there were something like 5 lecture halls with the same exam. There were approximately 3 proctors to each room. There were such stringent requirements for the exam. You couldn't leave until 20 minutes have passed, and no one could join after 20 minutes (to keep people rushing out and giving away the questions), students had to sit with at least an extra seat between them, and there had to be at least three different copies of the exams (color coded) to prevent cheating. Students weren't allowed to wear their hats, no calculators, and all bags had to be at the front of the room. About half way through the exam, two of the three proctors would circulate and check IDs against the name on the scantrons and the exam. If someone didn't have their ID, it always ended up being a bit of a fuss, because our supervisors expected every single ID checked. This was always annoying, since we had to cram ourselves between every table and desk to speak with each student in the middle of their exam. Highly disruptive, but that's what we were told to do. You can imagine we got a lot of nasty looks and grumbles. This setup was for every large lecture hall class. Including Precalculus, Calculus 1 - 3, and Differential Equations. And this was at the University of Florida, the flagship university of our state.

[@themasstermwahahahah]

I COMPLETELY agree that having fewer teachers, or just sal makes it easier and more enjoyable to learn. I have never talked to sal in person, yet i think of him as a personal mentor, i trust him, and he is engaging. He is a living example of a renissance man, and allows me to build enthusiasm for a completely unrelated subject, by building off shared enthusiasm for math for example. I have a parasocial relationship with him, and i can get straight to learning in every subject, without having to familiarize yourself with yet another person. I think this can also be seen in person, when you have a teacher again for a different class.

[@gabrielgarcia8256]

I am extremely grateful for this video. I was introduced to so many new concepts and I hope as a teacher that I can help make the vision presented here a reality. Similarly,, I don't know how many people know about the modern classroom project which is training teachers to create classrooms like the one Mr. Khan describes. I wonder if Mr. Khan and Mr. Sanderson are aware of this project and if some collaboration could occur.
