Khan Academy, which began in 2004 as a small collection of youtube tutorials by Salman Khan, a graduate of MIT and Harvard, has become a library of free educational videos that has has earned the recognition and support of the Bill and Melinda Gates Foundation and Google. With over 3,000 mini lectures in 15 subjects, mostly in sciences, technology, and math, Khan Academy’s mission of “providing a free world class education to anyone, anywhere,” is reaching across the globe, from rural Asia to classrooms in America, and is transforming the paradigm of education with a de-centralized, student-centered approach to learning.
At KhanAcademy.org, video lectures are simple, the only audio being Khan’s voice and the only visual a colorful virtual whiteboard. They are also short, each lesson about fifteen minutes long, despite covering subjects in diverse fields levels K-12. However, Khan has found that he simplicity lends accessibility. In an interview with 60 minutes he said, “I’ve got a lot of feedback from people who say it feels like I’m sitting next to them and we’re looking at the paper together…I think that’s what people like, the humanity of it.” In addition, the website also offers practice exercises and peer-to-peer tutorials, and software to track one’s own progress.
