I think when it comes to education we need to go back to the basics. We have made the system needlessly complex and it has not surprisingly failed.
A few years ago, at the university, all of us in the student housing co-op were required to attend a presentation by a HIV+ man. At one point he took out a small polythene bag. It had about 70 pills and he said that he took them daily for avoiding getting sick. The pills would make a substantial snack. So why so many? Well, there was this one yellow pill which boosted his immune system. But that made him nauseous. So the red pill was to suppress that. The three green ones were to compensate for the side-effect of the red pill, though. But if you take the three green ones, you had to take the 8 white pills to give you back the vitamins that the green ones made you lose. Now the large blues pills were required for the upset stomach that the white ones gave you when you had them in combination with the yellow pill, the one that you actually needed. The story went on till about 70 pills had been accounted for.
