Thank-you! It's a long time that I have a similar idea and I'm interested in developing it, but never found the time to dig deeper, with those references I will jump start in the subject and refine.

It's nice to know I'm not the only one thinking about that.

The trick for me is that it's a path in a graph for each student, so even if some component is not as strong for one student, he can fill the gap by taking another route. A good framework would be resilient if it finds many possible paths to reach the same result, and not forcing one path. But then, teaching in this way is more difficult.
