COMPASSION

Affirmation of life is the spiritual act by which man ceases to live thoughtlessly and begins to devote himself to his life
with reverence in order to give it true value.

Salman Khan Reaches Tipping Point

Online Learning, Personalized
By SOMINI SENGUPTA

The software program unleashed in this classroom is the brainchild of Salman Khan, an Ivy League-trained math whiz and the son of an immigrant single mother. Mr. Khan, 35, has become something of an online sensation with his Khan Academy math and science lessons on YouTube, which has attracted up to 3.5 million viewers a month.

Now he wants to weave those digital lessons into the fabric of the school curriculum — a more ambitious and as yet untested proposition.

This semester, at least 36 schools nationwide are trying out Mr. Khan’s experiment: splitting up the work of teaching between man and machine, and combining teacher-led lessons with computer-based lectures and exercises.



What makes Mr. Khan’s venture stand out is that the lessons and software tools are entirely free — available to anyone with access to a reasonably fast Internet connection.

“The core of our mission is to give material to people who need it,” Mr. Khan said. “You could ask, ‘Why should it be free?’ But why shouldn’t it be free?”


For now, Mr. Khan’s small team is subsidized by more than $16.5 million from technology donors, including Bill Gates, Google, the Silicon Valley Community Foundation and the O’Sullivan Foundation. He intends to raise an endowment. And this summer, starting in the Bay Area, where he is based, he plans to hold an educational summer camp.


It is too early to know whether the Khan Academy software makes a real difference in learning. A limited study with students in Oakland, Calif., this year found that children who had fallen behind in math caught up equally well if they used the software or were tutored in small groups.  


Mr. Khan’s critics* say that his model is really a return to rote learning under a high-tech facade...

But in education circles, Mr. Khan’s efforts have captured imaginations and spawned imitators. Two Stanford professors have drawn on his model to offer a free online artificial intelligence class. Thirty-four thousand people are now taking the course, and many more have signed up. Stanford Medical School, which allows its students to take lectures online if they want, summoned Mr. Khan to help its faculty spice up their presentations.


“What Khan represents is a model that’s tapped into the desire that everyone has to personalize the learning experience and get it cheap and quick,
said Jim Shelton, assistant deputy secretary for innovation and improvement at the Education Department.

Mr. Shelton predicted that there would be “a bunch of knockoffs” that would take the Khan approach and try to expand on it. “This is going to spread like wildfire,” he said.

In school math became Khan's passion. He came to see math as storytelling. “Math is a language for thinking,” he said.

The lessons are startlingly simple. Each one covers a single topic, like long division or the debt crisis, usually in a bite-size 10-minute segment. The viewer hears Mr. Khan talking, in his typically chatty, older brother sort of way. But his face is never seen, just his scribbles on the screen. More recently he has included two outside specialists to give lectures on art history topics like the Rosetta Stone and Caravaggio.

Today, the Khan Academy site offers 2,700 instructional videos and a constellation of practice exercises. Master one concept, move on to the next. Earn rewards for a streak of correct answers.  


...getting an entire class of ninth graders to master the fundamentals of math was never easy. Without those, the higher-level conceptual exercises were impossible. That is where the machine came in handy. The Khan software offered students a new, engaging way to learn the basics.

...the computer can do some things a teacher cannot. It can offer personal feedback to a whole room of students as they work. And it can give the teacher additional class time to do more creative and customized teaching.

 Teacher explains order of operations — the math concept that dictates the sequence in which calculations should be performed in a long equation. Handouts were passed out, and there was a series of questions and answers.


The Khan Academy software offers hints and instructional videos to nudge her ahead. It waits until she has mastered one concept before she can move on to the next. She can ask her teacher when she is really stuck.

*Critics:


“It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood, who strives valiantly; who errs and comes short again and again; because there is not effort without error and shortcomings; but who does actually strive to do the deed; who knows the great enthusiasm, the great devotion, who spends himself in a worthy cause, who at the best knows in the end the triumph of high achievement and who at the worst, if he fails, at least he fails while daring greatly. So that his place shall never be with those cold and timid souls who know neither victory nor defeat.”
Theodore Roosevelt (American 26th US President (1901-09), 1858-1919)
