0:00 welcome to the three takeaways podcast which features short memorable conversations with the world's best thinkers Business Leaders writers politicians scientists and other newsmakers each episode ends with the three key takeaways that person has learned over their lives and their careers and now your host and board member of schools at Harvard Princeton and Columbia Lynn tomman hi everybody it's ly tomman welcome to another episode today I'm here with s KH founder of KH Academy the free remote learning platform KH Academy is unique no one comes close to them in bread or in scale they offer lessons for all ages from prek through college they also offer a wide range of classes including math English History Science computer science and many others and they've achieved scale with over 30 million students per month and every month students spend about 2 billion minutes of learning time on conic

1:00 Academy today we'll find out what Khan Academy is doing now and how s reimagines education welcome Sal and thank you so much for our conversation today great to be here ly can you tell us how you came to start Con Academy yeah you know it goes back to 2004 uh my original background was in in computer science and in math but in 2004 I was a year out of business school post business school I found myself as an analyst at a hedge fund and I had just gotten married and my my family from New Orleans was visiting me in Boston right after our wedding and it just came out of conversation that my 12-year-old cousin naadia was having trouble with math I offered to tutor her she agreed so she goes back to New Orleans and we did you know distance learning uh a while ago and you know the early days was just trying to deprogram her her lack of self-confidence uh but then slowly surely she started to get that

1:53 confidence back she started to learn unit conversion which is where she had difficulty that was what caused her to be placed into a slower m class and then she got caught up and actually got a little ahead of her class and at that point I became what I call a a tiger cousin and I called up her school and I said you know I really think NAIA ran should be able to retake that placement exam they said who are you I said I'm her cousin and they let her take it the same naadia who you know was being placed into a remedial math class was then put into an advanced math class so I was hooked it was a cool way for me to stay connected with my young cousin I enjoy teaching tutoring I enjoy the academic subject so then I started working with her younger brothers then you fast forward about 12 months 18 months the little firm I was working for was just me and my perolio manager at the time his wife became a professor at Stanford so we

2:41 moved out to Northern California but more relevant to to your question word spread in my family that free tutoring was going on and so I found myself every day with 10 15 cousins family friends from around the country doing you know kind of distance learning and I saw a pattern that a lot of them just had gaps in their knowledge that they weren't it wasn't the issue that they weren't bright it wasn't the issue that they didn't have great teachers it's just that if you're in an algebra class but if you had a gap from fifth grade dividing decimals or a gap from sixth grade negative numbers it's very hard to address that in an algebra class that's just trying to teach you the algebra and so I started writing some software for them for them to practice and fill in all of their gaps and and all of these different skills and that was the first Gan Academy had nothing to do with videos uh and I write wrote a little

3:23 database so that they I could keep track of what they were doing and uh I was showing that all my friends knew that I had this crazy family project that I was writing software for them and tutoring them every night after work and my friend zulie said well why don't you how are you Skilling your lessons up and I said well it's hard you know even with 10 or 15 cousins I feel like I'm repeating the same thing over it's hard to cater to their individual needs and he said well why don't you record some of your lessons' videos and upload them onto YouTube for your family and I immediately thought that was a horrible idea I said YouTube is for cats playing piano it is not for serious mathematics but I went home got over the idea that it was not my idea and I I gave it a shot you know I just started making videos on stuff that I I was getting a lot of questions on and I started telling my cousins look watch

4:11 this at your own time and pace and that way when we get on the phone we can go a little bit deeper and after about a month of that I asked them for feedback and they somewhat famously and gave me the backhanded compliment that they they like me better on YouTube than in person and I took that as positive feedback and and at first it's counterintuitive like why would they like this video version of their cousin versus versus their cousin and they were saying well they weren't saying that they didn't appreciate me calling them and having the live Human help that was essential but what they were saying is it was really valuable to kind of have a a tutor on demand have an infinitely patient tutor to be able to access the explanations in the middle of the night to be able to access an explanation maybe they're a nth grader but they need an explanation for something from fourth grade they don't have to feel

4:54 embarrassed about it anymore and it also liberated our phone calls to go even deeper I was able to focus more on motivation I was able to focus more on uh unblocking them and and trying to understand their life circumstances versus just explaining the academics so I kept going as soon it became clear that people were not my cousins were watching and you know by 2009 there was about 50 100,000 folks using it and so that's when I quit my day job set it up as a not for-profit with a mission of free worldclass education for anyone anywhere and tried to fund raise for it and that first year was a tough year we were living off of savings our first son had just been born but by the fall of 2010 about a year into this you know quitting my a day job to do it we got some of our first real philanthropic support to to become a real organization and over the last 10 years we got to what we were just talking about it's

5:42 over a 100 million registered users now and tens of millions of folks around the world but you know I I still feel like we have a long way to go what you've done is extraordinary when you talk about starting this in 2014 most people don't realize that the iPhone hadn't even been created yet the iPhone came out and 2007 and yet you were scaling to 100,000 users you just said by 2009 so it's incredible what you've built so congratulations I appreciate that and there's so many things that have fallen KH Academy's way and my way frankly to help this become what it is but I tell a lot of folks I did a thought experiment I wrote a letter to 2010 s last year it's just kind of a 10 year anniversary of of when KH Academy became like a real organization and I think 2010 s could would look at 2020 n or 2020 KH Academy and say oh my God like we've grown beyond our dreams but the reality is the mission of free world-class education

6:36 for anyone anywhere it still hasn't been achieved and I think KH Academy from 2010 to now we've kind of proven that we can do something highly efficacious highly costeffective high social return and do it at scale at the scale of tens of millions but I think the next phase of KH Academy is actually going to be even more interesting can we scale a billions can we actually deliver over the next few Decades of literally almost everyone or everyone has access to a free world class education for someone who's listening now and isn't that familiar with Khan Academy can you explain a little bit about how it works and what makes KH Academy unique yeah so it's current incarnation of of khad you can imagine there's many ways to try to provide a free worldclass education for anyone anywhere and I I wouldn't claim that we've solved it as I just said it's a journey a lot of our early users and still a lot of those 30 million that are

7:27 coming every month are folks who need help with the topic so they might do a web search a lot of them have now know about Khan Academy so they might go directly to Khan Academy and look up the topics they need it's practice and the practice we provide on KH Academy isn't just you know four questions and once you do them you're kind of done whether you got them right or wrong for every skill and this is true in math we have math from prek all the way through the core of college we have science all the Sciences at the high school level we're hoping to build at the middle school elementary school level we have Humanities at the high school level we're the official practice for the SAT but the practice component of KH Academy allows for personalization and Mastery so for every skill there's actually from a student's point of view a functionally infinite set of questions usually there's about 30 questions per scale but

8:10 a student might do five or six at a time but students get as many shots as goal to establish Mastery and Mastery isn't just by getting four or five questions right of a specific seill they have to do that then they have to do it in a context switching mode then they can do it on unit tests and course challenges and then to support that practice there's solutions for everything there's hints there's videos those early videos that I was making for my cousins were really in support of the practice and they still are and we're hoping to add as many supports as possible including one of our strongest supports today is tools for teachers they should be able to be empowered with the same data that I was empowered with when I was tutoring my cousin so know who's progressing who's not how much time are they spending who's engaged who's not and what are actionable insights so that they can know who to intervene uh with

8:53 different students so our goal anyone can go it's all free it's all not commercial we have a KH Academy kids kids app that's actually reading writing and social emotional learning for the ages 3 to seven crowd and then we have the older KH Academy for elementary middle and high school and and early college age students where they can get as much practice and feedback as they need and you know the vision the hope is that we can keep doing this cover all core academic subjects do it in a personalized highly engaging way and eventually actually do some form of of credentialing why are we unique I think there's two layers of it I think one is maybe the ambition of the mission I think I think there there aren't a lot of organizations that are actually striving to do what we're doing of actually Tred to provide all core academic subjects across so many subjects in grades and practice and do it in a Mastery learning framework

9:41 that's engaging but I think if you get to kind of the the core of even you know how all of this started and and why maybe some of that original content that I was making for my cousins resonated and hopefully continues to resonate I think it it was fortunate that this started as a family project and I think people can sense that there is a I mean I don't want to cheesy but there's a love there's a love in it I don't know if that was grammatically correct there's a love there's love in it that thought came across that first content I was making for my family even in the videos it was very comfortable very conversational it really felt like we were at you know sitting at the kitchen table together I would crack jokes because I really didn't think anyone was listening and I think that eccentricity that Comfort I am someone my wife will tell you most of my friends will tell you that I get excited very

10:26 easily especially when I'm learning and so people I think can hear that and hopefully you know there's other people who also make content now but I tell everyone on our team you should not do what you're doing unless you're excited about it because whoever is the consumer of what you're doing is going to be able to sense and obviously that's obvious in a video but I actually think that's true whether you're writing software whether you're writing a text or even managing I think it's really important that you care and that you have passion for what you're doing because that translates into into all of the output but I I actually do think that is one of our secret sauces I can't tell you how many you know billion dollar publishing houses will put an Army of very smart people on something but the end product seems very sterile kind of stripped of all passion sounds like your GPS the next step of photosynthesis is where you

11:07 know it's just like you know as human beings we check out on things like that what are the other parts of your your magic your secret sauce I I I think it's that I think it's the comprehensiveness you know we cover across subjects and grades it's strange for me to say this I but when you think about the education space and you think about the notion of like a brand there's a lot of companies that you can list that have been in education for many years you know you can list the publishing houses but when people say are there brands in education you know where if you say that entity is producing something to you it evokes something hopefully something positive I think that's where we didn't set out to build a brand but I think when if you were to ask a lot of students you know what does Khan Academy mean they'll say oh that's like the this is the tutor my family could not afford KH Academy

11:54 helped me learn entire subjects at a rigorous at a rigorous world class class level that my class wasn't offering uh teachers will say it feels like my teacher's assistant hopefully they say I I feel like I know S I feel like I know the people who work at K Academy they've got my back uh K Academy is about Wonder it's about curiosity and I think that that you know hopefully carries through in our content it it has been said that data is the new oil you have millions of monthly users and hundreds of millions I guess billions as you said of of minutes of of learning views and 15 or so years worth of data you have the most data on education of anyone what have you learned from all that data we've been able to use data to understand which content is more engaging understanding which learning mechanics are more likely to keep someone engaged or not what which ones are more likely to drive learning outcomes and I think we're just

12:49 starting we're just scratching the surface I think as we go five 10 years in the future I'm hoping that Khan Academy can actually help push forward some of the learning science uh because it is a platform where we could very easily run experiments and with very very large data sets to understand what's what can really help students better learn who does KH Academy work best for well it depends what the use case is I think if you compare KH Academy as kind of a standalone resource and then you compare it to what the students had before like a textbook I think for almost all students KH Academy is going to be more engaging than their textbook and Khan Academy is going to provide more practice with more feedback and more supports than her textbook there it's a very clear benefit for for all students if you say what are the category of students that could just kind of run with Khan Academy on its own

13:41 and we see that we see millions of these kids but they're not the norm uh but there are millions of kids you know there's a young girl in Afghanistan who after the Taliban kept her from going to school KH Academy became her school and she just went super fast forward on it starting when she was age 12 by age 17 18 she had learned learned calculus physics chemistry biology economics she wants to go school in the US she lies to her parents goes to Pakistan to take the SAT because it's not offered in Afghanistan she does amazingly well she's trying to get to the US to learn theoretical physics Nicholas Kristoff writes a story about her meet Sultana the taliban's worst fear and that's what got her political Asylum last time I heard she was doing Quantum Computing research at Caltech so there are people like that and for them I do think K Academy is something like of a lifeline and it gives me incredible joy that that

14:28 we can play a part in you know unlocking people like that makes you wonder how many other people are like that if we can just you know get to them but I think there's a spectrum there's Sana at one end and then there's at the other end there's kids that need significant other supports and that's why we've always emphasized that KH Academy is best used when it's used with a really incredible teacher in a classroom and a social context because then you can get Best of Both Worlds kids can learn at their own time and Pace on KH Academy and as we said KH Academy is far better than you know paper worksheets or textbook in terms of supports and feedback and gamification but it also provides data to the teacher and far better to data than the the textbook or the worksheets would have provided and then the teacher can see okay who's progressing maybe they have some sultanas in the room but who needs some

15:10 more supports and they can take those kids aside do a more focused intervention it could be an intervention academically or could be like figuring out what's going on in their head they might have something going on at home and so that allows a teacher to get more leverage more scale and and really unblock the kids who need it most what are some of your recommendations building habits or anything else you see students succeed you see students struggle you see students persevere yeah well you know I'm a big believer in in habit generally you know for any parents and students watching whatever you think you or your child are capable of I guarantee you if you just pick a direction and dedicate even 20 minutes a day to that direction but that 20 minutes can't just be revisiting or redoing what you already know and what you feel comfortable with if you're willing to engage in things that are

16:00 essentially at your learning Edge that 20 minutes every day you'd be shocked how much it can build even in a month or two to completely changing your capabilities in that space and your perception of yourself in that space and we see letters all the time from folks who dropped out of high school who thought they weren't good at math or science or some other topic and then as you know maybe as an 18-year-old they want to go back to college or as a 20- year- old they want to go back to college they said yeah I spent the summer I just spent 30 minutes a day an hour a day on kic I started at 1 plus 1 equals 2 and I just relearned everything or filled in all my gaps and these letters these people are both happy and thankful but they're also angry they're like why couldn't I have done this before and now math is intuitive for me there's nothing it's not rocket sence even rocket science isn't rocket science

16:44 if you learn all of the fundamentals and learn it intuitively and get a chance to get practice and feedback so that's my my biggest advice is that you know pick a direction build a habit be willing to step out of your comfort zone and KH Academy is a great tool for doing that especially an academic context tell us about Khan Academy and Co what are you doing now yeah you can imagine when schools started closing you know when we even thought it they might close in back in early March is one of those moments where you you you look left and you look right and you say I guess this is us uh we could have never imagined this scenario but people would need something that is accessible that could work even on a cell phone at home that also has kind of a teacher School lens that covers across many subjects in grades that is hopefully that is trusted and if you put those constraints on it it's kind of KH Academy and even in theory

17:35 mult available in multiple languages where there's 46 translation projects of KH Academy around the world and so we started essentially creating kind of a war room within the organization of like what will the world need if schools get closed this is before we we knew that they were going to get closed we said okay we're gonna have to run webinars for teachers and parents to understand how to do this we're going to have to create schedules and learning plans for students so that teachers and parents know how to structure dat days where going as K Academy fit in but how can you use other things Zoom video conferencing to have a a decent distance learning experience for students to make sure that they don't atrophy and then soon as the schools Clos we saw traffic we were talking about the numbers earlier on a normal day during the school year we were seeing about 30 million learning minutes a day we saw

18:17 that hit 90 million learning minutes a day I suspect we go back to school this year it's going to go even higher and we just kept saying like what else does the world need okay the world's going to need better ways to fill in kids gaps because a lot of kids if they didn't stay engaged during Co they're going to have even larger gaps when they returned to school whatever return means and so we created get ready for grade level courses these are courses that have all the prerequisites up to an including the grade level that a students are able to enter they can take a course challenge if they get 80 or 90% of the course challenge then the teacher or the student or the parent can feel confident that they're ready for grade level if they don't they can keep working filling those gaps they can do that in parallel while they work at on their own time and Pace at the grade level course so we're

18:57 just trying to do a full court press right now and you know we're entering into a school year that is very likely to be distanced and you know people I know in the know on the vaccines and the therapies they think this is going to be a year there's a 75% chance that this time next year covid is essentially under control either because we have therapies that make it less scary or maybe the vaccine is is been broadly been available it's effective but they're telling me there's a 25% chance that this is a next school year might be affected as well and so you know we're trying to have that mindset what what do we need to build that's going to be useful for Co and frankly Beyond and we're also trying to Advocate that many people think in that way because right now I think in most of the education system they've been thinking of as this more as a rolling kind of one month or two month crisis and if you think of it

19:42 that way you're never going to come up with really strong Solutions where would you like to see KH Academy in five years or so well I think we want to cover all the subjects in grades and core academic you know from prek through the core of college I hope that our and this includes English and language arts and history and you know things that we we don't have as filled out yet I hope that you know our software is only that much more engaging that it can really you know we've really tweaked it so that kids get addicted to it in a good way we we see evidence that that's already happening for certain kids but hopefully that's happening for more kids and I hope that there's actually Pathways for folks work on KH Academy to be translated into opportuni so that like hey you learned X Y andz on KH Academy that's enough to get you this apprenticeship that's enough to get you this job that's enough to get you into

20:27 higher education and we have helped teachers really feel empowered really reimagine their classrooms really get to this you know utopian state or closer to a utopian state of where a teacher in a classroom of 30 is able to cater to the individual needs of all 30 students make sure that no kids are left behind so to speak in a world where anything is possible your your Isaac aimof kind of world the future and education is reimagined what would education look like it's a fun question I I would say it's a competency based world that if you know the material if you know and you know it could be academic material you know calculus or it could be like if you're a really good public speaker or you have deep empathy there's a way for you to prove it and if you prove it it's recognized anywhere around the world and it can immediately be translated into opportunity then there's many paths to get there and different paths are going

21:20 to work well for different folks I would hope that K Academy is a significant part for some folks K Academy might be the path the sultanas of the world for others it might be part of their path maybe it's Khan Academy plus their Community College in conjunction are able that to get them to the competencies that they care about that can immediately be translated into opportunity I hope that K Academy you know I have a Skunk Works project right now called Schoolhouse do World which is outside of KH Academy but I'm hoping to bring it in one day if it if it proves itself that it works which is matching human beings with each other to tutor each other and help each other and even evaluate each other and credential each other you know I hope that five or 10 years or dream state that you've you've allowed me to answer that that exists too that not only are you learning but you're able to connect with people

22:05 around the world and that adds a whole another dimension not only that would help engage people and help them learn the content and they can get credentials and get evaluated it'll create a true Global Community it'll create true empathy not to get hokey but you know you could imagine a t a student in Israel being tutored by a student in Iran or student in Pakistan learning from a student in India when you do that kind kind of stuff not only will they be helping each other as individuals but that I think kind of thing could build a lot of global empathy that is a wonderful Vision before I ask you for the your three takeaways the three key insights you'd like to leave our audience with today is there anything else you'd like to discuss that you haven't already touched upon as you you probably tell I I tend to you know sometimes have my head in the clouds but then I I very quickly want to make make

22:51 it happen but you know this situation we're in with covid I think you know we need to underline that if we don't get this thing right it's going to be a catastroph and getting it right is like we have to have a baseline a point of view of what decent distance learning looks like how do we support folks especially some of the most vulnerable students out there and I'm I'm I'm afraid right now because you know we're trying to do what we can we're trying to work with as many districts as we can we're trying to be a stop Gap if kids and families don't have anything else ideally we're able to use by the districts by the teachers so that we get the best of both worlds but I I actually think this might be a bigger deal than the pandemic I the pandemic is a big deal I don't want to make light of that but if you know historians 10 years or 50 years in the future if we have a year or two of 30 40 50% of the kids not

23:39 being able to really develop themselves I think that's going to have Cascades into society that we're going to notice in 10 or 15 or 20 years I would like to see more people acting with more urgency on this dimension of the crisis right now which might turn into a catastrophe and what are the three key takeaways that you'd like to leave our audience with today well you know what I just said is a little pessimistic but I think we can fix it you know the takeaways are I generally believe almost anyone can learn almost anything and that sounds very bold and very but I see it time and time again at Kan I get letters probably while we're talking I probably got a few letters from folks essentially talking about their own narrative saying I didn't think I could learn it now I can so that's one I think uh the second thing is you know there's some institutions or ways of doing things in our life that are so ingrained in us

24:25 because they've always existed they just seem like they were just delivered with that God came down and said Thou shalt do it this way and you do it this way but I think education is one of those systems where you know the education system we know was essentially developed about 150 200 years ago it really took its modern form its modern form in 1890 and I think there's a really interesting opportunity so that we can take it to the next level so not only will people learn more but all of the people involved in it the teachers the students Family actually enjoy it more and get more from it and have more energy for it so that's the second one and I think the third one is if we are able to do this if we're able to allow people to tap into their potential at a global scale I do think you know this is my science fiction hat on it would be like a a birth of a new Humanity that you could get to another another book I enjoy is

25:14 Arthur C Clark's childhood's end it ends with the Earth kind of Disappearing and stuff so you know I don't want to say that's what I want to happen but it talks about kind of humanity elevating to another level and obviously we've done that many times over our past the Advent of five the Advent of writing the Advent of of Agriculture I think if we truly had Global worldclass education for anyone anywhere and if it was truly connected to opportunity and people were really able to connect with each other we're going to get 10x the number of cures for diseases 10x figuring out ways to travel the cosmos 10x ways to avoid Wars and famines and figure out ways to feed ourselves and provide solve issues like climate change so yeah that's what gets me excited that's a very nice and optimistic way for us to end our discussion today thank you so much s for your comments today thank you so much ly if you enjoy today's episode you can
