I'm not sure what they're going to do with those who completely excel. I don't know where their place is. They learn concepts in spurts just as they grow physically in spurts. It's hard to criticize the sentiment behind this because it's an attempt not to penalize people for being average. It seems to be an attempt to say that average is okay as long as you're growing and working and moving forward.
Human nature is basically on the lazy side.
Human beings are not the kind of people who produce their best when nothing is expected of them. Human nature is not the kind of thing to excel when there's no pressure to excel. It would be nice if that were the case, but we are always looking for the easiest way out. It's not just in this particular situation, it's across the board in this country. It's been an underlying idea in education for a while, especially in the last ten years and it has been eating away at the quality of our educational system.
