There are few reasons to behave when students see a virulently disruptive kid returned to class after a few days of vacation (in the eyes of their peers) after threatening real violence against a teacher, throwing a computer monitor across a classroom, and/or being taken from the school in handcuffs for selling drugs in the restrooms. (Yes, those are real examples from my classes.) If there are no visible consequences for acting outrageously, why is there any need to control oneself?
However, if there is the possibility of being removed from sight, permanently, then those astride the fence will certainly take notice and think twice before following a bad leader.
You are absolutely correct but I'm talking about more than school choice. I'm talking about dismantling the education blob and letting parents and kids determine where and when they will attend school, if they attend any school at all.
Yes, I am well aware I am dreaming but it would be really, really nice to return to a system that worked until 1880 when state gov't stepped in and compelled compulsory schooling. (Yes, I do know that is redundant - I left it there for emphasis.)
