Leaving aside the issue that the charter movement (not all charters schools) is basically a grift, I do not understand how our supposed education reformer experts (they aren't experts, of course, just grifters) and the people who listen to them don't get that closing down schools and reshuffling teachers and moving kids around all the time has an incredibly negative effect on a child's education and mental/emotional well-being.
I moved around a lot as a kid. Going to a new school was very traumatic. You had to make new friends (or try to). You had to learn all of the unwritten rules/customs of the new institution. All of that is incredibly difficult for an 8-year-old. It's hard to learn when you're still trying to cope with the lunchroom etiquette.
