I had about the same exchange with my daughter. Her class is completely out of control. It isn't the teachers fault IMO but the result of a pantie waste society that can't discipline children anymore. The femanatzi movement has done a real job on our children.
It isn't the teachers fault but society's for not being able to discipline children?
When I was a little kid going to school, when I screwed up, I got a good thrashing/beating/The Belt..... as did plenty of other kids I went to school with by their parents.
.... we were still assholes, so was society back then just not tough enough and perhaps should have resorted to shooting us in the legs?
The reason why I claim it's the teacher's fault for not knowing how to control their class, is because not just in high school, but also in elementary, we used to switch from teacher to teacher, class to class. It was the same kids I was in the last classroom with, just like all the other times before..... yet where we would raise all hell and corruption in one class against one teacher, once we were in another class with a different teacher, depending on their own attitudes and disipline they brought into their classroom, you'd think it was a whole new set of kids in there, all quiet and doing their work.
The reason being is because one teacher would just contiually issue out warnings and threats of disipline, while the other teacher would actually carry them out after the very first warning, if we were so lucky.
It also has to do with how that teacher treats the students in their class.
My father, as a teacher, was a hard ass.... probably still is. But although he was hard on disipline in class and he'd drag students to the principle's office by the scruff of their necks, or even just kick them out of the school for the day.... when it really came down to it, respect was given where respect was earned. Where a student needed help with something, he was there. I've heard plenty of stories from fellow students I went to school with as well as others below my grade who had him, and all but a select few loved him as a teacher, I was told stories of how he just stayed after school to help them with their problems, social, class or personal.
When you are given a teacher who just works the job as a job and they put no effort or care in the students they are teaching, and they just continually recycle the same dicipline threats or continually talk down to you, then you're going to have a classroom such as what was described.
I sorta know, because I had a good hand in helping classrooms get like that in the past and I remember many of my reasons why. I'm not saying this is an absolute answer to the problem, but I'd say it covers a great majority of the reasons why classes can get like that.
