Basically, what he's getting at is that Khan Academy is not enough...which is true. While it's a nice collection of resources, the site is poorly organized and a reason to learn is not provided.This is why we need a service that maps out the prerequisites for real-life goals. "If you want to do X for a living, you'll need to learn about Y and Z and you can learn about that here."Right now, the best place to do that is on university websites that provide listings of their majors (Like this: http://www.franklin.edu/degree-programs/college-of-arts-sciences-technology/undergraduate-majors/computer-science/computer-science-bachelor-s-degree-requirements) That's how I figured out what to learn independently, but this isn't good enough because there are no links to free learning resources. I had to dig around for information a lot. It was hard.
Nick, that is pretty much what I am saying. And your idea of "backward planning" is certainly a logical and useful way to plan a path to one's goals.What I have seen in many years in education is the tendency to promote one way as the be-all and end-all in learning, that will solve all of education's problems, frequently without a shred of evidence. Obviously that cannot be the case.I have a cartoon about that at http://branzburg.blogspot.com/2012/05/get-on-bandwagon.html
