As Jeremy said earlier,
It would erase boundaries of class, and end distractions.
This was a huge problem in all of the schools I went to, and I know it affected the way I was able to be educated.
I think the schools need to take more interest in learning how people learn best, and offer different tracks accordingly. I am a visual thinker, I am right brained, I operate a different way than most people, which is why I took much better to classes which focused on a hands on, or visual type of learning.
Not all kids learn the same, and schools need to start noticing this and changing the way they do things, or you are always going to be leaving certain people struggling to get by, not because they are stupid, but because they learn different.
