Khan Academy brings lessons to iPad


Khan Academy has a massive library of academic lessons dating back to 2008. With an update to their app, the company now has 150,000 exercises that are available for the iPad.

Nathan Ingraham for The Verge:

Rather than just port all of the exercises to the app, Khan Academy took the time to add some iPad-specific features to make the experience fit the platform better. When looking at a demo for some geometry questions, Wahl showed me how you could touch and manipulate geometric figures to help answer the questions. Another math-specific feature coming to the iPad app is the so-called "friendly guide." The guide analyzes the questions you answer correctly and incorrectly as well as how long it takes you to answer and then suggests other exercises that'll help you in areas you're not as strong with. And all your progress now gets synced back and forth between the iPad and the desktop, as long as you log in with a Khan Academy account.
