Teacher to the world

Local entrepreneur Sal Khan jumpstarts the emerging global classroom

by Chris Kenrick

Can a hedge-fund guy find fame, fortune and fulfillment as a social entrepreneur?

Meet Sal Khan of Mountain View, an MIT-trained former hedge-fund analyst who is fast becoming — somewhat accidentally, as he tells it — math teacher to the world.

Khan's online tutoring service, begun as a sideline to help a long-distance cousin with her math homework, has become one of the hottest phenomena in the world of education, with as many as 300,000 students a day.

Khan was living in Palo Alto and working at a hedge fund five years ago when he first posted some how-to-do-algebra videos to YouTube as a way to tutor his cousin Nadia in New Orleans. The seventh grader, and later her brothers, Arman and Ali, loved them — and the math posts went viral. Khan kept on making videos, eventually quitting his day job to nurture the online, not-for-profit Khan Academy.

His short lessons — now more than 2,400 of them on topics from algebra to venture capital — are available to anyone in the world with a Web connection.

For free.

He appears to be succeeding where many for decades have tried and failed: attracting a global, mass audience to an educational website. Students from Alabama to Zimbabwe are flocking to the Khan Academy, and the videos are being translated into 10 languages.

The Khan Academy is "a glimpse of the future of education," says technologist and philanthropist Bill Gates.

Children in the Los Altos School District pilot-tested the self-paced Khan Academy in classrooms last year, and Khan is talking with other local schools.

Investors have knocked at his door — with notions for a company that could "do well by doing good" — but to date Khan has remained resolutely nonprofit.

The enterprise has drawn the backing of major education philanthropists, including Gates, Netflix founder and chairman Reed Hastings of Santa Cruz and, locally, venture capitalist John Doerr and his wife, Ann, and Intuit founder Scott Cook. Khan also won $2 million last fall from Google, in a competition where finalists were picked by Google employees and winners chosen by a public vote on the web.

Meanwhile, Khan says Cousin Nadia is "doing well," having recently completed her freshman year at Sarah Lawrence College in Bronxville, N.Y.

"I tell her there's a lot riding on her success," he said laughingly in a recent interview in his sun-filled office above a shop on Castro Street. "She's majoring in writing and pre-med, but I say that's by choice, because she was a rock star at math."

Born and raised in Louisiana, Khan first came to the Bay Area in 1998 fresh out of MIT, to work in high tech.

After a year at Oracle, he had moved to MeVC — a startup that aimed to make venture capital available to the public — when the tech market crumbled in 2000.

"I remember the day in the spring of 2000 when the Nasdaq hit 3,500 (down from more than 5,000 a month earlier) and I said, 'Let me see those business-school applications,'" he said.

At Harvard Business School from 2001 to 2003, Khan got acquainted with the world of hedge funds.

"It seemed both intellectually interesting and like a good way to make a living," he said, explaining his decision to go to work for Wohl Capital, then based in Boston.

When the boss's wife took a job at Stanford Law School, the venture relocated to Sand Hill Road and Khan and his wife took up residence at the Hamlet apartments, on El Camino Way in Palo Alto.

Talking with his cousins in New Orleans, Khan realized he might have stumbled on something important when they told him they liked his tutoring on YouTube better than in-person.

"Once you get over the backhanded nature of that, there was actually something very profound there," he told an audience in March. He was speaking at a Long Beach conference sponsored by TED (Technology Entertainment and Design).

"They were saying they preferred the automated version of their cousin to their cousin, because now they can pause and repeat their cousin without feeling like they're wasting my time. If they need to review something they should have learned a couple weeks ago or years ago, they don't have to embarrass themselves and ask their cousin.

"The very first time you're trying to get your brain around something, the very last thing you need is a person asking you, 'Do you understand this?'

"Now they can do this in the intimacy of their own room."

From the start, Khan saw no reason to keep his math videos private, and others began watching them. He was rewarded with feedback from "random people around the world."

One user commented that, for the first time, he had smiled after doing a derivative. Another responded that working through the same video had given him a "natural high and a good mood for the remainder of the day." Parents of a 12-year-old with autism said their son had found success with Khan's videos after other programs had failed.

"Here I was, an analyst at a hedge fund. It was very strange for me to do something of social value," Khan told the appreciative TED audience.

But he was excited by the feedback, so he kept on making videos. With his wife working nights and weekends as a medical resident and the East Coast hours (5 a.m. to 2 p.m. PST) of his Wall Street-oriented job, Khan had time to play with it.

"I kept making videos and hoping someone would notice," he said.

In September 2009 he quit the hedge-fund job to focus full time on the academy, digging into savings for the first eight months. Thanks to donations, the Khan Academy can now pay salaries to him and his small staff.

The academy's mission — "providing a free world-class education to anyone anywhere — has attracted, in the founder's words, "talent that money can't buy."

John Resig, a widely recognized JavaScript programmer, joined in May.

"Just by the nature of the mission, especially for people doing something creative whether it's engineers, or me as a video producer, it's the satisfaction of seeing your stuff being used and having high leverage and impact," Resig said.

Khan's staff today numbers about a dozen, plus six interns. To date he has produced every single one of the videos himself.

The popularity of the videos is due to their digestible chunks — each one is 10 to 20 minutes — and a tight focus on the individual user, Khan believes.

"My focus was to build a useful tool for my cousins and then, once it grew, to build something useful for the stand-alone learner," he said. "People like the style I teach in. It's very conversational. They appreciate that there's a human on the other side."

It doesn't hurt that the human is friendly, engaging and articulate.

The offerings are so basic that Khan says "it's shocking for me that this didn't exist 30 years ago.

"I'm surprised that an NGO (non-governmental organization) or the public sector never spent $1 million to $2 million to get the best lectures in core subjects in K-12 and distribute them at cost."

Khan's alma mater, MIT, was one of the first universities to make available its undergraduate and graduate courses on the Web for free, with its pioneering Open CourseWare initiative back in 2007.

"MIT was awesome when they did that," he said. "All the universities were talking about monetizing their brands, and MIT laid down the gauntlet and said: "No, these aren't our family jewels. This should be for the world."

But university lectures are much longer and harder to navigate than Khan's small, well-indexed bites.

The videos were embraced by parents, home schoolers and users around the world. About a third of the visits are from outside the United States, he said.

But Khan was surprised to get a query last year from a board member of the Los Altos School District. "We just assumed they wouldn't want to work with us, but they asked all the right questions.

"As soon as we started working with them, we found they were better run than most for-profit companies. (Bureaucratic) issues with the firewall were changed in half a day."

Los Altos uses Khan in what it calls a "hybrid learning model" in which students spend part of every math class working through new material at their own pace. Khan generates a data "dashboard," so at any moment the teacher can see how each student is progressing, or where some are stuck.

"Los Altos was willing to do something fairly radical," Khan said. "We didn't have to change what we were doing for that. I've got to give them a lot of credit."

Khan Academy enables teachers, parents and coaches to go online to help tutor a student.

Khan's finance and computer-science background particularly focuses him on "analytics" — using student-generated data to guide the user's experience and find the appropriate next step.

A student's results are available to authorized parents, teachers or tutors, allowing them to monitor progress and pinpoint strengths and trouble spots.

Khan's reluctance to form a for-profit enterprise appears connected to a spoken fear of "jinxing" the magic, and his evolving vision for the future.

"As soon as you get into the mindset of selling to a system —a school system or anything else —you adapt your product to the system. You end up trying to convince the bureaucrats, and they'll force it on the students.

"Here we have students and parents already using it, without forcing it on anyone," he said.

Khan imagines a global academic exchange, serving everyone from American students to middle-aged dropouts to street kids in Calcutta, which happens to be the birth city of his mother.

"Imagine what this can do for that street kid, who can't go to school because he has to help his family during the day," he said. "Now they can spend two hours a day to remediate it, and not be embarrassed by what they don't know."

People who got on the wrong track in high school can advance through the Khan academy and show what they know at 40.

"Imagine what happens if that student in Calcutta can tutor your son, or your son can tutor that kid in Calcutta. What you see emerging is that global, one-world classroom, and that's essentially what we're trying to build."

Khan said he feels better every day about the decision to stay nonprofit. "When I'm 80 I want to feel that I helped give access to a world-class education to billions of students around the world," he said on his website.

"I already have a beautiful wife, a hilarious son (he recently went on a second paternity leave), two Hondas and a decent house.

"What else does a man need?"

This guy is great! I first found him on youtube when trying to explain triangle angles to one of my children. Now, my children go there to learn regularly. My 9-year-old (who would rather have a play date than do math) calls is "fun." As an adult, I find it a great refresher, reminding me what certain terms are (e.g., prime factorization).

Great job Khan and keep it up!!!!!

This is a great idea.

In the information age we see how cheap and easy it is or should be to reproduce information and transfer it yet someone taking it from a brain to a brain or a book to a brain is problematic, expensive and very political.

I've seem some of the Khan lectures, and they are OK ... but the production values are low, they move slow, and do one thing, one problems. I found it slightly annoying to have to watch every letter, or symbol, or operator being written in long-hand on the small screen. I'd rather see a person in front a white screen ... I think that would work better and be more readily absorbed by what our brains expect from communication. Sure there is a lot of room for improvement, but I have to give him credit, he gets the job done.

Why can't we develop a best practices for this have something like this that is a pattern for our schools so we can reduce cost and target individual attention to where it is needed instead of just sitting all the kids by age in the same room assuming that age makes them the same. Why not educate people by what they don't know yet, or have trouble understanding?

The one thing the whole world need to understand is that by looking at our accomplishments globally we are not performing well or learning much - given all we know, all we can do and all the power and wealth we have. There is a reason for this that we all put out of our minds because we have learned we cannot do anything about it. Maybe we need to re-evalutate that?

Perfect redemption for being a hedge fund scumsucker. Too bad the others haven't followed suit - those that aren't in jail, that is.

You mean he's not from Palo Alto? Amazing there is intelligence beyond the city border.

Agreed, Tinyl. I wonder why they didn't just make him the feature story for their MV paper? Amazing that PA allowed an MIT guy to live in a neighboring town.

What Google competition was this, and are they running it again?!!!

Can't wait to try the lectures!

Salman Khan is the reason why I got an A in chemistry at Berkeley last year. For that, I owe him my life.

What a beautiful a human being you are to give something so precious to the world. When a person recognizes their ability to learn a concept they once struggled with, their self worth skyrockets, and that is another priceless gift that comes from your work. Our education system is broken, and schools are constantly forced to do more with less. There is an enormous need that you have embraced without greed, and I applaud you and your team.

Thanks to the Weekly for publishing this piece and to Mr. Khan for his vision and generosity in sharing his gift for teaching with the world. I have forwarded the link to people in other parts of the world who are keen to learn these things and also working on their English. Funny, just last week (before the article appeared) someone mentioned the Kahn Academy to me and I had no idea what it was. I feel so blessed that the Weekly picked up the piece of educating me on this! We need more inspired people helping educate the world. Thanks again for a positive story!

This is like Wikipedia - it's not often a cool service such as this resolves to stay non-profit. Good for them!

Absolutely great stuff. Everyone should check it out, because there is something there for everyone. With all the slashing and burning of public education by the "no new taxes" people, Khan's model may just be our saving grace. Kudos!

Making good educational videos is not as easy as Kahn makes it look. Lots of people have tried to imitate his style of videos. His entire system of study and tracking are pretty good.

As more and more hedge fund managers end up in Club Fed for SEC violations, it is a good thing that Mr Khan saw the light and changed professions to so etching much more respectable.
