I think my point is how one could know exactly what knowledge do they need to solve their problem. And how can they apply things they’ve learned to solve that.

1. I suspect that whether current principles and knowledge in education truly change that fast. It’s true, “data and information” flow rapidly now because of IT. Can we infer that it in the same situation for “knowledge” as well ?

For example, I don’t think a mathematical proof methodology would change fast, though it evolves through time.

Anyway, this question also involve with the definition of knowledge.

2. from spec No4. , I support in using knowledge for applications. Though, I want to emphasize that applications do vary across many levels, for me, more than what were stated in spec No. 4.

Application of graph theory may be about social network modeling, yet no one can use this model for anything in everyday life.

My point is the application of certain knowledge may not be able to utilize for social but still very beneficial, because its application of application of application are very useful in everyday-life level. Then why not we immediately find the application which really useful ? The answer is one specializes in different things (as we want this to happen).
