Salman: As I just introduced what Khan Academy is most known for

Gerund

is this library of videos that I started producing

Before I go any further, let me just show you all a little bit of a mix

and then we can go a little deeper from there.

So the hypotenuse is now going to be five.

These animals fossils are only found in this area of South America

a nice, clean band here and this part of Africa.

We can integrate over the surface in the notation usually is a capital sigma.

National Assembly they create the committee of public safety

Notice this is an aldehyde and it's an alcohol

start differentiating it to affect or, and memory cells.

plus the 20 million dollars from the American manufacturer

if this does not blow your mind then you have no emotion.

You know the videos there's now 2,200 of them.

That's kind of what I want to do until I get a hit by a bus

We're doing a lot more than that,I mean the videos are reaching ...

Actually now, on the order of about two million unique users a month.

they are being watched 2 to 300,000 times a day.

Before I go any deeper, I actually just gave a talk at TED down in Long Beach

a couple weeks ago, I don't want this to be a repetition of that talk.

But before I go any further, I want to get a sense

just so I know how much background and depth I need to give.

How many of you all have been to the site?

Because I want to know how much background, okay very good, very good.

What I want to focus on today is kind of going a little bit deeper.

I will give a background about what we're doing beyond the video portion.

We are actually kind of a team now, we're at six people.

Some of the questions that I think have surfaced

is we've gotten a little bit more popular and we started to enter into domains,

but frankly I never thought we would enter.

Before I do that,I want to give you all a little bit of a thought experiment.

Imagine if we're in a juggling class and I'm your juggling instructor.

This week we are going to learn to juggle oranges.

I give you all your orange juggling kits, I give you all each four oranges

and I give you all a lecture on juggling oranges.

I say practice and in a week I will assess your orange juggling ability.

You practice and a week later I come back with my clipboard and I say juggle.

You try the best you can to juggle and different three oranges,

four oranges, all the rest and I say, "You can't juggle four oranges at all."

"Three oranges, barely can keep the oranges in the air"

You are a 70% orange juggler, you are a D orange juggler.

I put it in your permanent record making it all

but impossible for you to go in an elite juggling school.

Despite those deficiencies that you clearly have in your abilities,

there's the state mandated a juggling curriculum that we have to follow

and there's a calendar that specifies how we have to move forward.

We have this kind of assembly line and so I say,

"Well give me back the oranges. The next lesson here are some knives."

that's exactly what's happening in our classrooms right now.

It might not be as physically dangerous but it is just as mentally dangerous.

We have students they take an exam, they get 10% wrong,

20% wrong, 30% wrong, you can even fail an exam.

Regardless of the fact that we've identified those deficiencies,

we know that the student doesn't know those concepts,

we have to move on to the next concept, we have this assembly line.

That the only thing were using the test for is to put labels

on peoples foreheads to separate them, to track them.

Though we know there's weaknesses we push them forward

and we're pretty much ensuring that at some future point they'r going to fail.

We're pretty much ensuring that motivated kids,

even if they have awesome teachers at some point

those gaps are going to come back and they're not going to be able to perform

once they get to some more advanced mathematics.

just so you know a little bit of the story how all of this happened.

I was literally making videos in my closet for about five years.

Then about a year ago Google brought me over to their campus

and I thought it was just like a lot of the Google engineers,

as parents they were using these videos for their children and all of that.

But they brought me in to a conference room and they said,

"Sal, what would you do with two million dollars?"

I said, "Is this an education context? Or is just a broader question?"

That happened and a little bit later, I mean this is like last year,

I get a call from Larry Cohen, who's Bill Gates chief of staff,
