So a win-win?
The drill sergeant approach is to announce that something shitty (epic homework assignment, whatever) is assigned to the whole class whenever GirlX, Y, or Z disrupts the class. Two or three rounds of that, and somebody will kick the ringleaders ass without your Mom having to be involved.
They'll hold them down in the bathroom and beat them with a bar of soap wrapped in paper towels till they blow their own brains out (but not before the teacher too....) What's their major malfunction? Kubrick FTW!
Heh
If OP's mom is too nice for that approach, you can alter it. Give the class a "carrot" first, like early dismissal, open book on quizzes, whatever. But, tell them it goes away if the asshats continue being asshats.
Your mom really just has to scoop up her ovaries and become a disciplinarian. If it goes past that point, that's what school security cops are for. Those lil bitches can get removed from class and fail and ruin their lives if they wish. But sitting in class being a disruption can't fly.
School security cops? I think only a few of the "diverse" inner city schools have those around here.
My tolerance for teachers and their constant complaining has reached an all time low. Bitching about how hard they have it when they get every fucking holiday known to man off, 2 months of summer break and nobody giving a fuck what they do in their own classrooms. And now the teachers are getting bullied? Tell those kids to keep their mouths shut or get the fuck over to the principals office. Solved.
If you were walking down the street and a 5 year old kid came up to you and started talking shit to you, would you be offended, or would you find it funny?
Little kids are like drunks in the sense that they genuinely couldn't care less about sugarcoating the truth. so you never know. but you have a point as grown men/women should be self-aware to the point where they can't easily be affected by a fucking opinion.
