I'm sorry but you're wrong here. Kids need to learn that everyone is different and everyone is not treated the same. The oft liar is never trusted. The fat kid is probably the one that stole the candy. The nerdy kid probably did most of the group work. If you get good grades, the teacher gives you more slack in some areas.

And your example sucks. Putting your head down and "listening" is not the same thing as sitting up and paying attention to a lecture but not taking notes.

Don't get me wrong. I see where you're coming from and agree generally, but on academics, there's too many different ways to learn. Whatever someone figures out that works best for them should be left to that if their marks are good every evaluation.
