I wouldn't call it exactly the same... The biggest difference that frequently gets glossed over is the Coaching interface. In normal schools it's hard to get one-on-one tutoring with someone who can actually help, as well as with someone who knows exactly what you're struggling with. I'm sure most people who've done tutor work have encountered students who can't even describe what it is they're having problems with, they're that far gone.

What improvements do you hope to see? Making it easier to find short-term tutors would be on my list, throw up some IRC channels that tutors can monitor and get notified of students seeking help. I think one-on-one teaching is the most optimal.

As for how easy it is to learn, as long as we aren't hardwiring people's brains with information as seen in The Matrix learning is going to still take work. (Not necessarily hard work in every instance, but work.) I'd like to see more ways to interact and make the knowledge part of one's own experiences rather than as received truth (something Polanyi got mostly right in his Personal Knowledge book). Of course I'm instantly suspicious of any technique or product that tries to oversell its ability to teach concepts faster with better retention, and even more suspicious when it tries to sell itself as "it's so fun the user won't even realize they are learning!" That said, I can see benefits of various systems over both doing nothing and the status quo. Tools like Anki for instance work well, if used. The advice some programming texts give to manually type the programs also has obvious benefits, basically a subset of techniques that train the mind to follow and notice common actions. (There was an app linked on HN a few weeks ago that replicates the motions of solving algebra problems without actually doing any algebra, I can see how "eliminating two like things from both sides" feeling "okay" may help some people a little.) Khan has mentioned that he has offline students watch lecture videos as homework and do problems or answer questions during classroom time, the opposite of the traditional school, I can see its benefits over the traditional method too for classes where information is typically transferred via lecture.

What things like KA, AcademicEarth, and Wikipedia all have in common though is that they change the utility function of learning. That is, when they're not being used as crutches to get through the traditional schools. Students can learn what they want, when they want, stress-free. The classical model is "pass the tests with scores above this threshold or die." (Not literally of course.) It encourages cramming and forgetting. Cumulative testing doesn't help because the course only lasts maximally 9 months (with a big break in the middle), and at higher levels only 3-4 months. Sometimes it's even just one term rather than a full semester. It's not enough. Add in repetition of the wrong things (it's always the most basic things that get repeated endlessly when they're the easiest things to remember!), poor communication between professors of what they actually cover, poor communication between student and professor of what the student actually understands, fixed deadlines, anxiety over money (whether living expenses or paying $1500 for a dumb class), anxiety over spending X hours of your life for a useless class/assignment, retaking the entirety of a class instead of focusing on what you're missing specifically, being forced to take classes one has no interest or skill in, being exposed to one resource, et cetera, it's amazing the classical system works at all.
