BTW, the answer to disruptive students is to remove them. Will never happen.
Public schools teach to the slowest kid in class. Or the kid who isn't interested in learning. That holds the rest back. You aren't allowed to exceed and succeed. If you want to fix education, that stops. You remove those you can't, or won't, keep up. Put them somewhere else. But, of course, that becomes like prison. They then learn all the bad things the others do. On the upside, the bright students flourish. This is the system until HS. And even the basic classes in HS still suffer from this. You have to take advanced or college prep classes.
However, if the "lower level schooling" has too many minorities in grades 1-8, it's RACIST!!!!!
So our public education will suck forever.
