The ugly truth is that kids don't study because they aren't expected to.
Let's face it as long as their kid gets that perfect GPA and is obedient enough most parents don't give a damn that they actually learn something. To my peers it's just a ritual they need to complete in order to have a good "life" whatever that is.
In fact, my teachers have scolded me for trying to derive stuff on my own. It is quite obvious to them that I should be spending time practicing to get marks instead. Who cares if I actually know that electric flux is only the field lines that penetrate the surface? As my teacher put it they'll check my mark sheet instead.
So, is it any shock that students don't study?
I know that I am learning the secrets of the universe in some ways, and what within my textbooks lie answers to questions that people have pondered over for centuries, but the truth is that no one else gives a damn. They know what a muon is because they need to know what a muon is. They can't see nature and they really don't care.
No one expects them to create things, that's left to those nuts like me (someone said this to me point-blank). What is expected of them is status, prestige and a good paycheck with a stamp that they won the rat race of life. Nothing more. Nothing less. Oh and a big house in the suburbs to show that they have arrived won't be too bad either.
In the end, this is a problem that is core to us as a society. Most kids are a mirror of how they were brought up, and only if they are taught to see things differently can the status quo change, but as anyone may tell you it takes integrity and it is just too damn hard.
