- www.ted.com Salman Khan talks about how and why he created the remarkable Khan Academy, a carefully structured series of educational videos offering complete curricula in math and, now, other subjects. He shows the power of interactive exercises, and calls for teachers to consider flipping the traditional classroom script -- give students video lectures to watch at home, and do "homework" in the classroom with the teacher available to help.

That voice that taught me throughout school, oh man.
He is a revolutionary and he is helping millions - he certainly helped me! Sal Khan deserves a nobel prize!!
without a doubt
Right
Absolutely!! Khan Academy has literally helped me so much
He helped me too!
Yeah I also think that. I think the noble community is drunk cause it has not given sal sir a noble prize.
Sal Khan is very very smart. Truly an academic genius. He can teach math from elementary school level to AP levels and some college math courses, chemistry from middle school level to college general chemistry level, finance from Wall Street fundamentals to everyday life financial markets, and many many more things. He is such a great explainer and note taker. I am so grateful that he is a man who makes academics so much easier to learn
I think he might have other experts helping him write the scripts, but what was really brilliant was recognizing the potential of online learning
@@theminuteman6211man perhaps, but to understand them all so well and so quickly and then to be able to teach us all takes real skill. But I acknowledge your opinion too.
yes he got like cs , mech eng, maths bachelor degrees from MIT and a MBA from harvard so no doubts on his smartness
This guy deserves a noble prize
Salman seems like a really down-to-earth guy. What an inspiration he is for human mankind!
+MrKaplanFilm ;) Well said
Kahn Academy is free of charge so I wonder how he's making any money. I hope he is making a lot of money.
did you hear what he used to do? hes probably retired
Travis Uhh What did he do?
the other salman khan on the other hand.....
"I give you a bicycle and maybe give a lecture ahead of time, and I give you that bicycle for two weeks and then I come after two weeks and say "Well, let's see. You're having trouble taking left turns. And you quite can't stop. You're an 80 percent bicyclist. " So I put a big "C" stamp on your forehead and then I say "here is a unicycle"."
I appreciate your point you're trying to make, but all universities I know of provide free tutoring, office hours, and TAs. If at any point during those two weeks you struggle learning to bicycle, there are several resources to exhaust before you can truly say you tried your best to learn how to ride it in those two weeks.
@@christianalvarez5409 problems start long before college too :(
@@christianalvarez5409 and also the aforementioned problem of feeling uncomfortable to admit incompetence on a thing you were expected to get ages ago.
I get that the system is getting blamed in an unnecessarily harsh manner, but this is still just a better way.
@@christianalvarez5409 I didn't know elementary schools have TA's, tutors, office hours and all that you mention. Can you name one elementary school with all those?
@@ElTioCaiman Did you read the comment I was replying to? Here it is copy and pasted:
"I give you a bicycle and maybe give a lecture ahead of time, and I give you that bicycle for two weeks and then I come after two weeks and say "Well, let's see. You're having trouble taking left turns. And you quite can't stop. You're an 80 percent bicyclist. " So I put a big "C" stamp on your forehead and then I say "here is a unicycle"."
This isn't describing an elementary school. Elementary schools aren't lecture-based, and kids aren't expected to go home and practice/learn on their own for two weeks before taking an exam. This is describing at least a high school, but more than likely college-level course, and that's what I was speaking on. Unless you yourself would like to name a public elementary school that this would be describing?
I've got so much respect for this man. Humble, smart and has even helped me through university and high school many times.
All the money we've spent on education and the solution is outside the system.
Isn't it always?
The solution isn't outside the system. As he said, this creates a time saver. It saves teachers the time of lecturing, of making/grading quizzes, of trying to teach 30 students a complicated idea in under an hour and then sending them home to (hopefully) practice it with competency.
Because students can come to class with the tools already in their arsenal, teachers can then use the time together to use that knowledge dynamically and creatively. That includes rocket building, experiments, problem solving, collaboration, discussion, service..the possibilities are really endless.
If this could become available in a way that teachers can personalize and take ownership of, I would use it tomorrow. But I teach World Language, so his website is not for me. I can either use my own rudimentary version of that website, or use other teaching methods.
The system is also designed to free parents up so they can work etc.
Yet to be discovered, though alluded to here, is the power of peer teaching. Over 100 years ago there was a school with one teacher, 10 senior students learning from the teacher who also each taught 10 other students, who then each taught 10 other students. Each student was learning enough to be able to actually teach the subject which is very deep learning. When this happen, in concert with this type of video resourcing, the earth will change even further.
Peter Howie Good idea but needs monitoring. Peer teaching in victorian uk schools was unsuccessful as wrong ideas got transmitted and were never challenged. Properly trained teachers use learning psychology whereas pupil peers do not. Teaching assistants in some uk schools can fulfil this role. Parents teach part-time in subjects they barely know themselves. Fine as long as proper teachers still tackle the more difficult stuff and are available to fix problems.
yes it is outside of a system cause you only do not need schools/ teachers but mentors who can help you but not to dictate what to learn - for that you just do some tests do discover what one is good at & enjoys at the same time
I like his take on how kids learn at their own pace, and how indirectly, it proves that labelling kids as "slow" or "gifted" is a silly thing to do. It's all a coincidence of time. We grow and develop at different times, we have different ways of learning etc...
I thought I could never understand or like mathematics. I loathed it.
I then came across Khan Academy, and I was so sad that I had never ever been come across the real 'mathematics'.
And it was all because of this legend. Man, today I like Math, I study Math, I love Math and I live Math.
Thanks to you Khan Academy and Sal Khan. 😁😁😁😁😁😁✍️✍️✍️✍️
This guy should be in congress to teach those guys a lesson on education reform.
Many of the people in Congress get kickbacks from teachers' unions and don't want to reform education.
The fact he does this on his own time, no profit. Just a guy that want's to help others succeed. If that's not class, I'm not sure what is. Wish others were like this guy. Making a difference. I hope I can do the same.
Kinda ironic, I've learned more from Sal than any previous teacher. Haha! :)
Interested to know how your career has shaped up! Did it help. How big an effect it has had over the last 7 years
sal, if i had a large photo frame of you, i'd literally keep it in the temple room and pray to u everyday! ive never come across a tutor who has even 10% of the clarity in explanation as you do! thanks man :)
online learning is great. i have been using khan academy now for about 2 months and i went from grade level to 3 years ahead.
Khan Academy is a game changer. If Salman Khan and Elon Musk remain relevant for the next thirty or so years, the future of our world will look much, much brighter. These men are real role models
ohh its been 5 years and they are more popular and better than ever
Idk about Elon man. I use to like him, but the guy is no role model
Remember when you said something about Elon? Yes, sir he is the richest man in the world living in mars now.
Yeah and we no longer tweet, we X…
But Khan is doing some cool things with AI, using it as a coaching tool.
Khan is doing incredible things, and has essentially pioneered democratizing of education, it's very beautiful. Musk is an intrepid moron that throws money at projects until they work, and is now palling around with white nationalists. They took different turns in life.
I heard about Salman Khan several days before, but I didn't take care, nor did I search for anything about him. Today I stumbled upon a problem in math, after a long time googling and reading, I decided to search for a video about it, then I found Khan Academy. It's so clear, concise and intuitive, what's more, it's even free! I just cannot believe it! Hats off to you, sir!
This is pretty awesome. I have been teaching in various capacities here in Hong Kong. The Swiss cheese holes missing link analogy couldn't be more appropriate for most people in Hong Kong. Teaching them computer skills is especially painful when they have not mastered drag and drop; humanized ways of labelling files..etc. Worst of all, the education here rendered them not to question. Most stumble on through without filling the gaps, and the frustration builds for both the teachers and the students. When asked to go back and master those fundamentals, how ever simple and crucial they might be, they are reluctant, and think that it isn't necessary.
Salman Khan understand the meaning of civic duty. He exerts much effort to informing the public and providing proper education, and he never expects a reward for it. That is selfless service.
I cant even explain how proud and excited I am for living in times like these.
Didn't realize Khan academy had a practicing program. Just went through the test on rational exponents and I now understand them a lot better.
Salman is amazing!
Indeed. Everything is on point.
LiveEdu dot tv have already done this, but they do not focus on beginners. LiveEdu made focus on professionals wanting to create their own products/programs. They now have expanded their topic to 9 which are all related to technology including cryptocurrency. You should check them out!
I've been studying mathematics on Khan Academy. I haven't had a math class since my junior year of high school (going on 7 years ago), and I'm really rusty on a lot of things, including some things that most educated people would consider fairly basic.
It's really nice to be able to relearn those things that I haven't used in a long time (such as multiplying two multiple-digit numbers, which I rely on a calculator for) and some things that I actually never learned in school (such as tricks for determining divisibility by a few 1-digit numbers). I never feel like I'm being judged for having to relearn some of those elementary aspects of math and I'm even given points as a reward for watching those videos and doing challenges related to them.
Since I spend time with a community of people who make computer games (some as a job, some as a hobby), I know some people whose math knowledge goes into graduate-level calculus which goes _way_ over my head. You have my word, internets, that I will keep studying until I understand those kinds of subjects and I will keep going even beyond that. With Khan Academy, MOOCs, and all other sorts of open education resources, the barrier to education is lower than it ever has been in the history of civilization.
Viva la educación!
Your passion for learning is uncommon. Keep going, all the best!
Thank you Sal, you've taught me so much :)
He changes the entire way of learning. He made a greater contribution than Confucius on education. The modern issues about teaching are inequality of teacher distribution and only can focus on the whole class. The future Salman Khan talking about let us can focus on every individual student and give them equal teaching resources. and on some level minimize the resource we invest on teaching and even get greater return. Salman Kham will be remembered as long as the history goes.
LOVE LOVE the "flip the classroom" concept! Wish I had had it growing up in school, it would have changed my life!
What is It?
Sal talked about it early int he video. It basically means having the lectures at home, and the "homework" in the classroom. A teacher was having students watch Sal's videos at home, and then do problems in the classroom. Which is a great idea because it means the teacher can be there with the students as they solve problems. So the students can quickly get feedback on what they got right, and what they need to work on.
Thanks mate.
He's got the right idea. Pupil's working at their own pace, teachers being able to see clearly each pupils progress, and more importantly, pupils are engaged through a context that is relevant to them. Brilliant to see.
Doing the homework in the classroom, watching the lectures at home is the best idea I've heard for school in a long time. The whole project is absolutely brilliant.
Khan Academy are easily the leaders in this field. I started my TH-cam channel for my students two months ago and doing the "Flipped Classroom" model is THE BEST thing I've done teaching-wise! Highly recommend their services and their model!
You're the reason why I started loving organic chemistry
The Khan Academy website is all about school, work, jobs, businesses, EVERYTHING! 🌞
learned a lot from him. khan academy is the best
+A tax funded religion Are you afraid they can spoil math? Like make you believe 2+2=5? Actually this seems to be happening already. Think of the official version of 9/11. May be if more people study physics, thanks to Khan, why not, we'll sure have a better world with less slaves believing government lies. ;-)
Despite your "free" offences, you didn't respond to my question. You can choose the old fashion books, if you like, and not the "evil" Khan, to learn to understand other's point of view and try to interact in a fair way.
Edmondo Duma Actually if you set 2 as a variable an set it's value to 2.5, 2+2=5.
MScience Only letters can be set as variables, isn't it?
A Steel Cup No. Any thing can be a variable. @=x^4+4x Then @ is a variable. Anything can be a variable if you set it as a variable.
I see no reason to dislike this video.. still 89 people did it..
Qualified teachers see the threat to their jobs/professions.
TheIbroxPreacher This doesn't replace teachers. It makes teachers more potentially effective. But it's a new tool -- a new box of tools, even -- and new tools need to be learned.
TheIbroxPreacher Although granted, that may not stop someone from seeing it as a threat. :)
Neeraj Singh Some people are anti-technology. I have a bit of anti myself since I think overusing computers can sometimes create a tangible divide between the student-teacher connections in traditional classroom settings. But I still love khan academy and I'm showing this video my teacher. :D
Neeraj Singh And I'd rather teach my own students then have someone do it for me but that's kind of a selfish considering that its probably in their best interest to be able to go at their own pace.
A great Bangladeshi-American , Sir you have our respect .
probably one of the best ideas i have seen in a long time. i use this website to help review and sometimes jet ahead of the class because i understand it already. and tbh it feels pretty awesome to know everything of what the teacher is saying and just sit there helping other kids that are struggling. i am thinking of talking to some of my teachers of this next year and see what they might do.
This guy right here saved me countless times for school!!!!!!!!!!!!!!!!!!!
i actually love him so much! I've missed so much school due to my health and he is the reason i can keep going with my subjects
Massive respect for Sal 👍👍👍
My first TED Talk and it was for the Khan Academy! I use this for my college developmental math and my son uses it for his elementary level math. This is a great program. This man Khan sounds like a guy I would like to meet!
Khan's videos show and tell; he's one of the earliest educators to use multimodal elearning.
I just love Salman Khan, he is a fantastisc person, with a great work. I have seen a lot of his inspirational videos, that really helps you learning and get back on the track. So if you haven't seen his videos yet, then i would recommend you to see them!
I use flipped classroom and videos all the time in my teaching practice. I love it, but it's definitely been a huge time investment to make quality content for my students
Khan Academy is just Incredible,
that helped a lot of students belongs to any aspects
I think the one thing no one talks about is the concentrated effort to build intuition into every topic. When I was at school, I couldn't understand a word of vector dot product (like most others) and then I stumbled upon the dot product video. Within ten minutes I understood what had confounded me for ten years. I think thats the greatest strength of Sal's videos. Keep it simple and people will get it. He never jargonizes anything
Thanks Khan ... you have revolutionised the education system !!! .. You have definitely succeeded in giving back to the society in such a tremendous way ... god bless you ..
Sal Khan.....hats off !!!
like it......
I am amazed. This consistency of data points, and ability to truly track a child's progress and difficulties is a foundational aspect of learning that should have been in place a decade ago. Genius!
TEDs like this make my entire day happy. I am so pumped up. I have posted it on facebook, and even sent it to everyone I know, this is a must watch for everyone.
Great things can happen by accident if you do what you love and follow your gut.
I learned that from TED. Thanks for posting!
good bless you sal... Thanks for helping me for my acturial study exams.
Happy Teachers day to you Sir, you have revolutionised the teaching in modern times..🤗🙌🙌🙏
I found Khan Academy about a year ago and I've fallen in love with the site! Sal is such a great teacher and his videos have motivated me to jump back into college. I watch his videos everyday and study as many math sections as possible in order to review for the calculus courses in my upcoming semester. The site has helped me identify my deficiencies in algebra and trigonometry that have led to my previous failures in college; simple rules that I forgot as far back as 5th grade!
so much respect for this man
This is going to be my first year teaching GCSE Computer Science. Thank you for your Python videos. I tried a few of your maths video (I also teach lower school Maths) with my students last year. They worked very well. I like the analytical tools you have implemented and will get the Computer Science students signed up this year to make full use of them. I must say, I am really excited about using more of my class time in 1:1 with students.
I have to say, while I'm done with schooling I would love to have used Khan Academy at least as a help if not as an entire system to educate myself. I can only imagine this system as being more succinct, without teacher error (which happen more often as you move on to advanced topics), and more interesting as you basically can decide over a weekend where you don't have much to do to literally race through as much of the curriculum as possible. I think calling 10 straight correct answer mastery is a bit of a problem. It seems to me you'd need a bit more than that. Looking at Khan Academy's youtube channel I'm glad to see they are still churning out new educational material.
Two guys sharing stage.... one who democratised software and put forth its excellence throughout the world.... and the other who is using that software touch to educate millions !!
Hats off.
Absolutely fantastic! I have seen this video a couple of times now, and every time it makes me smile!
He puts all his videos up for ...free! I just love it! This is the future!
I tried some courses on coursera but they were not as good as ones on Khan Academy. however, I hope that Khan Academy will have more and more courses about subjects in university.
thank you so much Khan!
Still going strong!
With Gates backing up, there is wonderful future of education. Way to go Salman Khan...
as a future teacher who is finishing up my credential program, I am beyond excited to implement this into my classroom. talk about differentiating instruction and meeting kids at their level. simply brilliant!
You know.. his ideology for academics in general is just superb and specially for a country like india where academics is not seen as something you actually like...but is seen more as burden... just to get a spot in the stupid rat race for the engineering colleges. India really needs this kind of a system and i hope he holds some workshops etc here so as to change the odd mindset regarding academics
If we consider it as a burden, we learn slowly. If we see it as fun, we learn rapidly the same thing.
Salary of Salman Khan

2012 : 348,229 USD
2011 : 348,879 USD
nutan Pillai he deserves billions!!
Whenever I feel overwhelmed in academics, I rewatch this video. Salman Khan has been more of a tutor, for me, than any other tutor / teacher, in my personal life, ever has. Even though the learning relationship is parasocial, I've benefited a lot from studying through Khan Academy. I feel truly grateful to him.
Coming from a strong video background, media based education such as this is defiantly one of the best ways not only to convey useful information, but help people retain what they have learned. Bravo Khan!
great, I would like to follow khan academy . thank you.
Balika Kamble Have you? In case you haven't, you can still try it: www.khanacademy.org/
MIT and harvard master ... if he want he can earn highest salary but he doing good thing of free education (if he earns as side product that is good too) ...
I literally think what Sal has done here may be the best form of education for everyone ever know to man kind. God bless him
I’m in college rn and every Tuesday and Thursday, I go to two Math classes and just listen and jot down notes but not actually take in what they’re saying. It’s almost like they’re expecting all their students to be geniuses and to understand what they’re teaching. We’re expected to automatically understand on the first try, and there’s no going back. Once they teach a concept, then on to the next. However, I’m glad Khan Academy exists because now I can go to his videos and learn the same subject I was just “taught” in a much easier way. I can even pause the video or go back if I need to. For me, I want to be a teacher, but it also helps to make sure that (one) your lessons/lectures can be understood, and (two) you are going at a pace that is reasonable and helpful to each student. It sucks that a man who is using technology and only his voice can be a better teacher than those who are face to face with their students. You would expect more communication, and for those who are teaching secondary and primary, you would expect that their teachers would know of their students are struggling. As a future teacher, I will try to make sure my students understand, and if I need to reteach, I will because it benefits them. I don’t want them to go on to the next grade level knowing nothing of what I taught. Also as a teacher, I will encourage my students to use other sources like Khan Academy if they need to understand the lesson more. Every student learns in a different way and some need multiple perspectives to finally grasp a concept. Man sorry I ranted, but I’m just tired of teachers teaching a lesson but not really teaching their students.
He made a TH-cam channel 100x more competent than most schools out there, and it's fucking free.. across the board FREE. This guy may be the reason to why kids of this generation and the next will be some of the most competent students to date. Something is terribly skewed with the world if Kissinger, Arafat and Obama are eligible for a Nobel Peace Prize and this guy isnt. Give it to him.. Now please..
Back when Ted Talk used to be great.
Jay Fayza I
Agree
I am so, so thankful for the website. I am using it to help me study for the GAMSAT (medicine entry exam in Aus & elsewhere) but am super impressed by the potential implications for young students. I currently work with youth who have a disability and may struggle in some areas of learning -> this site could be a total blessing for them. I love the idea of increasing teacher contact time.
I also really like the idea that this could potentially revolutionise the way that people in developing countries are taught, with access to some really amazing teachers and supports across the globe, for free (provided they have access to a computer with internet!). Amazing.
oh my god, how amazing this way he and his team doing now, thank you Khan
Inspiring!
@16:40 those expressions on sal's face after meeting bill gates :D
+Keshav Sharma Lol, i noticed that too. He's like, "Is this real?"
Proud Moment for sal :)
This is truly what changing the world means. What a brilliant person.
Sal Khan got one of the best Ted's of all time
Omg that bicycle metaphor...!! We need more teachers like you! :)
I wonder if he is related to the great Genghis.
If I remember correctly, something like 0.5% of the world's population (or some percentage like that) is related to Genghis Khan.
I think I saw that in an ad for History Channel on TV.
His parents were both Bengali Indians.
I am sure the chances of being genetically related are extremely acute.
Look at his nose...looks a bit like Obama's
Pioneer of modern Education System.
Khan Academy
i just love thia guy he helped me 3 years of college and still helpinh during my fourth year thank u for existing
LOL khan sal looked super nervous talking to bill gates
Hang that dislikers, Even Bill Gates understands that that guy is GOD.
LOVE SO MUCH THIS PERSON, i understand much more maths and its everything because of khan academy, im so grateful with his work, thanks thanks thanks
I love this guy. Charismatic yet informative lectures on mathematical concepts. Helped me a lot.
Khan Academy made me realise of the good education that I’ve been deprived from having. I’ve learned so much through Khan Academy that never made sense in school. Thank you, sir!
Khan Academy can be the future of education. The solid mind behind it can keep it going and put it on a global scale.
Sal might be my favorite person on planet Earth. That voice brings so much nostalgic comfort. Some random guy I had never heard of or seen before took so much time to explain concepts that I had knowledge gaps in.
I received my bachelors degree in Computer Science without fully understamding what Calculus and Differential Equations were for, though I could solve the problems. When I was going for my masters in Comp Sci - Machine Learning, Sal helped me fill in a lot of gaps that I had developed over the course of my education. I can't thank this guy enough.
I think that Khan academy is the most worthwhile project that has ever been put on the internet. As Donny Miller said - "In the age of information, ignorance is a choice."
sir this is the only channel i use for studies and it has helped me more than my teachers in my claas in india. Hats Offfff to you !!!!!!
Putting this system to work + using the data to compensate high performing teachers = MASSIVE LEARNING REVOLUTION
Watching this video almost 8 years later has really given me an appreciation for much of a visionary Salman Khan was/is. As Salman predicted videos are being used today in classrooms as a substitute for classic lecture style learning environments. This, as Salman predicted, has this has enabled teachers to direct more of their time to help students who struggle which in the past was not possible. Internet videos have allowed students (and people in general) to use the internet as an extension of their own brain. As a student over the past decade, internet videos have always been available when I did not understand something that was talk in class. These videos have allowed me to constantly revisit them giving me the ability to relearn older material when I was ready to pay attention.
As a future educator, I plan to incorporate internet videos into my classroom environment. Firstly, is a teacher watches some videos on the topic they are trying to present it allows to adjust their instructional plan based on a carefully curated and edited version of it; this allows the teacher to improve their teaching habits. Secondly, I plan on giving students (whenever possible) analogous videos to the lesson they are being taught; this allows students to have little perfect lessons whenever they need a reminder. Whenever there might not be a video available I may make my own videos for the students to refer too. It seems to me that videos have an essential part of the classroom and educators who do not consider using these videos are making their jobs harder.
Mr /444 +888 +444 /696570121271966 /+@+
I don't know why, but seeing the passion in Sal's eyes almost makes me cry. Thank you, Sal, for caring enough about education to develop a system where no one is left behind. This is a huge problem in our schools today, like you said in the video.
This is awesome! I really wish I'd had this in school. I was in the advanced track, ranked in the 99th percentile on the gifted and talented scale, but never got the foundation in middle school algebra because I didn't get the time and explanation necessary for me to understand. By the time the teacher realized that I was falling behind, we were too far for her to go back and walk me through things because she needed to advance the rest of the class. This is worth talking about.
This is what I'm talking about you know?
Great man..we need more of these guys..
Thank you so much! I came across this from an ELL Webpage, and the video's are helping so much!! It's nice to have some backup, as an ELL teacher I'm constantly correcting students, and I even get tired of hearing myself talk so it's a great break for the kids!!!
I agree with a lot of this. It's so much more helpful when the whole class is working together. I'm in the 12th grade pre-req to calculus at school, and I love that my classmates and I discuss the math and teach each other alongside the teacher. It's a much more friendly atmosphere and it really does help.
I love the education and how our society is changing a lot. Bless you. Best wishes from Huánuco - PERÚ.
I wish these were available a few years earlier. You are brilliant sir!
Who hasnt come across Khan academy website and took their notes or watch the videos. But its great seeing who Khan was... and the history. 🤗
We can see clearly he´s very shy ! A wonderful teacher .. and shy. Incredible.
