| > Charter schools kicking out problematic students isn't some loophole, it's the main point, and it absolutely can improve the education for those that remain. If you kick out the problematic students, the only students you have left are easy to teach non-problematic students. > and it absolutely can improve the education for those that remain. It isn't mysterious: you selected the best students, so your results will be the best. It is a direct application of selection bias. Public schools will be left with whatever students are not accepted into charter schools...those "problematic students", and will...again...due to selection bias have worse results. > It's not like they're only accepting kids with two parents, in fact they're doing a much better job of helping poor families in my district than the public school system That's great for your district, but parent pointed out ending school at noon on Wednesday are going to apply selection bias. Perhaps your district does it better. |
Maybe the negative effects of having problematic students is enough that its a worthwhile endeavor? By Middle school or high school "problematic students" involves people that not only are noisy and disruptive in class, but people that deal drugs, rob people, steal, join gangs, bring weapons to school. Just calling them problematic is really underselling the situation. And the effects of a student that routinely swears at a teacher and causes fights disrupts a large number of students preventing them from learning things.
