A free, world-class education for anyone, anywhere: this is the goal of the Khan Academy, a passion project that grew from an ex-hedge funder's online tutoring sessions with his niece, who was struggling with algebra, into a worldwide phenomenon. Today, millions have viewed and subscribed to the Khan Academy's YouTube videos, which have expanded to encompass nearly every conceivable subject. Like all great innovators, Sal Khan established himself as an outsider, with no teaching background to tie him to broken models. And his breakthrough idea has become his life's passion. Schools seek his advice about connecting to students in a digital age, and people of all ages and backgrounds flock to the site to utilize this new approach to learning. In The One World Schoolhouse, Khan will present his remarkable story, as well as his vision for the future of education. More than just a solution, his book serves as a call for free, universal, global education, and an explanation of how his simple - yet revolutionary - method can help achieve this inspiring goal.
