A Free App for iPad that Shows Knowledge is Power:
I think I’m going to like Khan Academy for iPad better, and why you might, too.
Khan Academy is a virtual learning environment founded by Salman Khan, who is, in his own right, a bit of a super human. He holds several degrees from several prestigious schools covering a wide range of disciplines including mathematics, electrical engineering and computer science. The academy’s mission is to provide a top notch learning environment to anyone who wants to use it, free.
These are not lessons cobbled together in an incoherent mass that you have to wade into to tease out the classes you want. The subjects are organized and categorized, and cover lessons geared to students from kindergarten through college and beyond.
Take math for instance. You can start with the very basics - addition, subtraction, multiplication and (my personal favorite) division. You scan through lessons you may be familiar with and move on to more advanced lessons covering fractions and trig to differential equations and calculus. The Science and Humanities categories are similarly laid out, so finding what you want or need to learn about is easy.
