I think this reveals a lot of ignorance on the huge amounts of different teaching methodologies and techniques that have risen and fallen over the last 100 years.

I have spent 15 years in the educatuonal system and I feel I am qualified to state that the methods are very obsolete.

A week of playing Kerbal Space programm gave me better understanding of orbits than years studying calculus, physics, general and special relativity.

It has poor applicability in everyday life - we learn all the biology of a cell but kid's don't know the difference between aspirin and ibuprophene.

Afaik Kerbal's simulation is non-relativistic, so you shouldn't have learnt anything about relativity from Kerbal...
