Khan Academy change education

Khan Academy，由Salman Khan创建。此人1977年出生，拥有MIT的三个学位：数学学士学位，电子工程与计算机科学学士以及硕士学位；他还拥有Harvard大学的MBA学位。

2004年的时候，他为了教自己的侄女，用Yahoo的Doodle Notepad给她远程授课；后来因为很多亲戚朋友向他求助，2006年的时候，他注册了个Youtube账户，开始录制视频课程上传到Youtube上。2009年，他干脆辞去了金融领域的工作，专心于他的Khan Academy⋯⋯

Watch. Practice. Learn almost anything—for free.

What started out as Sal making a few algebra videos for his cousins has grown to over 2,100 videos and 100 self-paced exercises and assessments covering everything from arithmetic to physics, finance, and history.
