With the backing of Gates and Google, Khan Academy and its free online educational videos are moving into the classroom and across the world. Their goal: to revolutionize how we teach and learn. Sanjay Gupta reports.
agree he really changed the world, I went back to school, college, and I graduated with honors...how, khan academy!!! Guy needs to be worldwide!!! humanity will be sooo much better!!! he needs to get the noble prize !!!
+LOMES art class video resources or, some people don't want to be taught. Not to sound narcissistic but look at all those middle school students hating every minute there
+LOMES art class video resources I disagree some people don't like learning. But it depends on the subject. Person x may hate learning math but he loves learning about art.
This literally made me weep. I'm 56 yrs old, after being diagnosed with adult ADD and struggled all my years in middle school and high school and then afraid to go to college, I am excited for the kids who feel like they are left behind but now have Khan Academy!
I really respect him and don't know about rest of the people in the society, but he definitely didn't only change my life but also changed my perspective toward education and purpose of life.
خان بھائی! آج آپ کو پڑھاتے ہوئے دیکھ ہی لیا آخر!! بہت خوشی ہوئی یه جان کر کہ آپ کی اس محنت اور لگن سے دنیا بھر کو فائده پہنچ رہا ہے_ ایک عظیم کام ہے جو آپ سرانجام دے رہے ہیں_ خوش رہیں!!
+Aldora LaPlume That's great. The most important thing when it comes to math is to learn stuff in he right order, and always make sure that everything is crystal clear. I would say that Arithmetic/Algebra/Geometry, in that order, are probably the fundamental subjects, and this will take you really far.
***** It's also important to develop a good intuition for things, so that you don't rely too much on formulas. One example is the cosine formula for triangles - it is pretty easy to derive that formula from scratch by splitting an arbitrary triangle into two right triangles, and then comparing their respective sides and angles and finally combining them so that the cosine of one angle only depends on the sides of the original triangle.
***** Indeed. However, it might sometimes be more practical to start with simply presenting a formula if it has a complicated derivation, so that the students at least can start using it. For example, the area of a circle pretty much requires calculus to be derived properly, since you will have to do something like taking the integral of the areas for an infinite number of rings of greater and greater radius - for example, you could say that one ring has the area 2·π·r·dr and then integrate this from 0 to R, which will result in the area of the circle --- π·R². This would be straightforward if you have some knowledge of integral calculus, but it might be too complicated for people who are just starting out with Geometry and most likely at that point have knowledge of Arithmetic and Algebra, although they could probably understand the general ideas.
How to become educated at home, without being gagged by tuition costs! This video clip came on after I watched the video clip emailed to me today by sal, thanking me for my donation to the Khan Academy. Yes, I support these guys - it helps a lot of people!!
Khan academy is awesome. I learn new angles to concepts I know well, which makes it a great review. Like people say, the pause button is tremendously valuable. The idea that you don't have to go to class when you don't feel up to it. Skip around content when reviewing to break up monotony. I'll bet anything math and science achievement goes up in people who use it.
This guy is EPIC!!!! seriously online tutorials are the best thing ever, once I learnt the concept, it's really much more easier for me to do the exercises and THINK. Instead of snoozing off in class!!!!(since my maths teacher also took khan 's approach to teach us now)
What a concept... world class education and all for free. Who would've thought of that. How about a world class health care... all for free... is it at all possible. Right... What do you say Sal.
Sciba Trista For now I think it's better for students to use it as home to learn a concept better if their teacher didn't explain it well enough (high school)
So I sucked at math during high school only c+ was my highest grade. Teacher in no easy way said I was hopeless. 14 years later I took maths 2 passed with a- working with my teacher and watching khanacademy videos. 1 year later took calculus 1 passed with a b+ was sick during that course and missed a few classes so mostly khanacademy concepts brought me through that. Now I plan to do physics and more sciences along with calculus 2. I am grateful for Sals dedication as my daughter is now top of her class in math and increasing in other areas redefining her study methods.
It was probably your teacher who was hopeless, then. Good teachers can teach things to anyone, because they know how to reach out to every student. Some teachers have this annoying attitude that they almost seem upset when a student asks questions that "are obvious", and that's exactly the kind of attitude that intimidates people to ask questions in the first place. If a student is unsure of something, then he or she should always feel comfortable to ask about it, and NEVER feel "hopeless".
Agreed I started teaching and saw massive growth in students. I always believed in making classes open for dialogue and laughter. Took an IT class from an average of 20% to an all out class average of 75% in less than a month. I was called in to help them pass their final exams. Teachers need to understand that it not only takes loving your job, it takes loving your students.
Exactly, and I'm glad to hear that. Actually caring for the students makes an incredible difference, and makes the whole climate much more friendly and welcoming. Of course, the courses should be taken seriously and sometimes need to be formal, since you often need to use formal language to clearly explain how math and science works - but there is nothing that says this should exclude a relaxed teaching style and a sense of humour. One lecturer that I have a lot of respect for is professor Gilbert Strang from MIT, he is a good example of how I think teachers and professors should behave during a lecture.
I am a LPN returning to college for my RN degree after 15 yrs. I came across a science lesion on skin a few months ago. I watched it in addition to all my assigned reading. Last night I was so burnt out from reading I kept falling asleep. The peripheral vascular system is not very exciting reading material. So I googled the doodle instructor for help. I refreshed my knowledge with the cardiac and peripheral vascular systems and enjoyed it. As a AADD visual learner, Khan Academy is amazing!
I love Khan. I found him last year when I was searching the four fundamental forces. I instantly subscribed to him. He breaks it down so much that you have to grab he concept of it. Now he's helping me excel in biology and geometry. Thank you, Khan! :)
I love khan academy, and my precalc also does a "flipped" class. But there's one problem...I get home at 5, sometimes 7, so its difficult trying to watch the videos and learning the concepts. If I took easier classes, it would be heaven.
THIS is truly heartwarming and inspiring. A man actually making a change in the world with the gift he was given and not for his own selfish needs. Definitely deserves recognition!
I'm ecstatic to see that Khan Academy is helping students of all ages. Me personally, I don't know if I would have made it through college without his videos. Absolutely amazing, and I'm not at all religious but I will say that he is a gift from the heavens! Such an inspiring human-being!
Sal Khan is a Superman.. Great teacher.. Generous person ...willing to share all he knew to everybody in a simple and easy way .Everything absolutely free. All the best .May God bless you.
Learning is always better when its on your time. Students don't want to listen in class. They'd rather socialize and get distracted by the dumb kids. They learn better when they decide to sit down, shut up, and pay attention when no one else is around to distract them. Great website. I use it in my classroom.
This guy is absolutely wonderful. He actually cares about the kids in this world and he will change it for the better with such a big heart. I don't know how in the world I can thank him; he has helped me so much!!
My mom make me use this for my homeschooling. It really help me because I'm autistic and dyslexic it helps me understand what it is. if a teacher try to explain this to me i won't understand them. it helps alot
when i got introduced to khan academy back in 6th grade, I groaned because of the more learning I would have to do. But it's only after entering high school that I realized this is actually a huge help, especially for all the AP classes I'm planning to take. The fact that the founder can break such complex things into no longer than 15 minute vids, a miracle and my forever grateful heart.
I am a 40 year old man who grew up with major learning disabilities and I have learned so much in the past year; most of all a deep understanding of maths. Thank you Sal!
I love it and I'm a teacher who has to lecture due to no texts and no funding for computers. This needs to happen and funding to improve classroom technology needs to go hand in hand!
Mr. Khan, thank you that you teach me. I always wanted to study medicine but I have cerebral palsy. So I study health education and special needs in education at one university. Hovewer, it is not enough for me. I am still searching for new informations and from time to time I watch your vidros. Sarka Sedlackova, Czech Republic
In the Age of Coronavirus...THIS IS A REVOLUTION whose time has come!!! World Class education FOR FREE! Why are hard workers penalized from succeeding (i.e. paying so much in (property) taxes to build buildings that have nothing to do with education) when Khan Academy could be instituted everywhere? Parents...make sure your local school board knows about this; talk to your politicians who champion education. Break the grip that teacher's unions (administrator heavy/salary heavy) and get the teachers on board to push this 21st century form of education to the forefront!
God Bless you, Khan! You give so much and nobody has to not even pay half of a cent? You deserve every Blessing this planet can ever think of! Thank You, Khan! Good Blessings To you and your family!
The two problems with the Khan Academy approach for mathematics are: - It tends to help people who want to learn to repeat processes rather than understand concepts of mathematics. - 15 minutes +- of color coded bad handwriting is not ADHD friendly. What the Khan Academy is doing is an important step but there are still a lot of holes. It is not for everyone. The future is having a dynamic AI engine that massively customizes instruction to fit an individuals wiring and talent.
I'm attending paramedic class at high school in Norway. We dig deep in most topics within anatomy, physiology and pathophysiology. Khan Academy has helped me a lot, because not only does he explain it simple and he starts at a beginners level, he also shows you why and how things work. Reading a text about the hearts electrical system, is barely enough to understand it. Me, and most of my classmates need to SEE how things work, to understand it. It's also a LOT easier to remember if you have a visual memory of a physiological function. Thank you Khan Academy, for making my education a lot easier!
Cooperative learning is very important. I agree with Meagan. Discussion is valuable. Khan is great for a small part of teaching. Not everyone learns the same way. That's what teachers in the classroom do. They teach to meet their needs. Visual, auditory and tactile learners have different needs. Khan is a great tutor but does not replace teaching in the classroom.
I use khan academy at school and even outside of school to learn new things and what I like about it is that it's free unlike Ixl and other websites that are not
I am studying to become a Cytogeneticist; your Organic Chem videos REALLY helped to refresh concepts and learn new ones! Thank you, Salman! I intend to use your videos to help my son learn 6th grade Math lessons :) Keep up the great work!
I am 47 years old. I want to get my GED. I tested last year at the local GED class and tested at a 5th-grade math level. I have sat and studied alone at home day and night for the last three months and am ready to take my GED and am confident I will pass with a high score. I love this guy. He is the best. Bless you, Sal!!!
I would like to add that the instructers at the GED class do not know what to do to help Adults. I was so frustrated. I cant afford the expensive online courses. I wouldnt be able to get my GED if it wasnt for this. I am going to take the test in the next week. I am so grateful to you Sal!
Oh I forgot to say that this is not easy for me. I dropped out of the 8th grade in 1986. Thank you Sal. If I had to pay for this. I would never get my GED. I can not express how blessed the world is now that you have given us all this gift.
what i do with the khan academy is this. When I am in class i tried to listen and take notes however at home before i start homework i always replay the lesson on Khan academy. SUPPORT KHAN BY SPREADING THE WORD
