Guess what, I went to a HS that had plenty of fights too. As soon as the fight broke out, security came running. It usually ends in <3-5 minutes. Those students then get suspended. So, yes, I've witness what bad students too. Which is why I said there should be segregation of those type of students apart from those who wants to learn.
As I've stated, I'm not a professional teacher and I won't kid myself into thinking I can personally handle the violence. But that's why I said I'll call security instead of trying to handle it myself. As an adult, you should know what you can and can't handle. If you can't handle these tough students, then move to a school where this won't be a problem.
You're mixing two different problems. Proving that there are bad students have nothing to do with disproving that there are bad teachers and how tenure is retarded. Just because you prove the sky is blue does not disprove the leaves are green. Both flu and I stated we had bad teachers in Honor/AP classes. These students are ready to learn. There were no students acting up in these classes.
Please don't lump me in with politicians. You like to do that a lot. I was not talking about "failing schools". I was talking about bad teachers. Yes, the problem is very complex, but no solution can arise when neither side concede that they're part of the problem too. At least I admit there are bad students and parents. You on the other hand things the bad teachers are few and far in between. How can you have an honest discussion about a solution when you're not aware of the whole complex problem?
