Why post (repost?) an article from July 3, 2012? Khan Academy has changed a lot since then. Khan Academy works well for my two younger children. AFTER EDIT: I'll mention some of the changes that Colin kindly asked for news about. As a lot of Hacker News regulars know, several of the Khan Academy developers regularly visit Hacker News. Some of those developers have interacted specifically with me both on-forum and by private email to ask sincere, action-oriented questions about how Khan Academy mathematics lessons can improve. One suggestion I made a couple years ago was for Khan Academy to arrange its lessons in a "knowledge space" like the competing commerical online program ALEKS,[1] which I like very well for my homeschooled children. Another suggestion I made was to make sure that the online work was more of the nature of "problems" rather than "exercises,"[2] and the Khan Academy developers have come up with some very innovative online mathematics problems to ensure that learners don't merely passively watch videos but actively learn new mathematics. Simply put, I think Khan Academy is iterating successfully. In many respects, I am in direct competition with Khan Academy as a mathematics instructor who teaches in-person lessons for which fees are billed, but I am happy to let my clients know about the existence of Khan Academy, happy to see my own children use it for a lot of their own mathematics learning, and happy to see schools adopt Khan Academy as they "flip the classroom." I am very much a both-and kind of guy when it comes to mathematics instruction--I like to mix and match a lot of programs--but I think Khan Academy has a useful place in the mix.
