In the system as I envision it, you'd be free to call a tutor/teacher for help with a concept at any time. In the interest of lowering barriers to entry for self-studiers I want there to BE free layers of help available.
Yes the crowdsourcing layer depends on some technology and some heroes, but I also think that would help us refine the courses. We could probably also mine the question classifications from tutor requests. Again sucessfully linking it to the concept that hung you up in the first place would be best.
As far as teaching the test, what I'd be working towards is a test environement where the questions could almost be infinitely randomizeable per student so rote memorization wouldn't help.
There is actually some research that shows making the questions harder makes you remember the answer more, so the questions are deliberately written in a way that makes them more difficult. This concept bugs me a little because I want the classes to be exactly as hard as they need to be, and no harder, however if the data proves this helps people retain longer (we can randomly test people later maybe offer them free tutor minutes for answering) then its in.
Everything about the program will be as data driven as possible towards refining the education product to the best student experience/outcome.
Initially I'd like to attack the corner cases where Big Education isn't established. Right now colleges are spending a lot of time teaching High School Math and English, so classes that were the equivalent of High School Math and English that brought up your scores before you took the placement test in school would save you thousands of dollars.
There are a lot of training classes for jobs skills that are only taught by the vendor that makes the equipment, whether this is assembly line robot programming, or greenhouse irrigation equipment I'd like to get involved in the space.
According to Cornell there is nowhere you can get a 4 year degree in Controlled Environment Agriculture (Greenhouses, Hydroponics, Aquaponics) so the standard in the industry when opening a new greehouse is to poach someone elses foreman or make a lot of mistakes learning on your own.
Other places where I'd like to get involved are colleges that don't have their own online program yet and don't have the cash for one of the established providers, and not enough tech savvy to make an open source solution work.
