Granted, most people use software to find antiderivatives, but someone has to understand how to do that. Where in mathematics courses would the necessary knowledge be taught that would convert, say, (x^3 + x^2 + 1)/(x+2) into x^2 – x + 2 – 3/(x+2)?

]]>I’m not so knowledgeable about Scratch, but I’m currently using a derivative of it: App Inventor 2, which makes programming Android devices unbelievably easy, even for kids! If you’re not familiar with this, check out http://appinventor.mit.edu/explore/ and view the Beginner Tutorials associated with the Hour of Code. They are only about 5 minutes each, and you will be astonished at what can be accomplished.
