Giving teachers the right to physically fix a student's attitude in class, would be a great way to keep a class under control.   

Everybody has had a kid in their class when they were in school, that would disrupt the class' learning and the teacher's teaching. Usually these kids get kicked out of class and maybe end up being sent to the principal's office. But after a few times of paying the principal a visit the student doesn't seem to mind going to the principal's office because they realize that the principal can't do very much( thats what happens when there is no real punishment.

Some ideas to solve this problem would be giving teacher the right to smack students, separate students into different learning levels or just kick the disruptive students out of school. If teachers could beat the crap out of students like they used to be able to students would be more likely to listen in class because they would know that there are repercussions to their actions. Instead of now a days were all the students know that a teacher can't touch them. 

If we put different learning levels in school students would be able to learn with students that are of their learning caliber( so the idiots with the idiots and the smart kids with the smart kids). That way the disruptive or uninterested  students would be together, the average students would be together and the advanced students would be together. And that way the dumb kids will be able to feel a bit smart compared to when they felt like complete idiots when they were with the smart kids. The only students that might not like this would be the dumb of the dumb kids because then they will just be considered unfit for school and they might as well start applying at a Mcdonalds'. Some might say that this wouldn't work because if your in the lowest level then your looked down on and don't have a chance to do something with your life. Which is find of true unless you show improvement and go up to the next level. 

Kicking these disruptive students out off school for good is also a good idea it may not be as fun as smacking a kid but this way you get rid of the problem permanently. This solution might not turn out well because we would have a whole bunch of kids hanging around the streets with nothing to do but cause trouble, so maybe that isn't such a good idea.

Personally I would prefer to give teachers the right to beat the smug face off of those students that think they have the right to disrupt other kids' education just because they plan on working for minimum wage for the rest of their lives or that they don't plan on working at all and living off of everybody else.  They have to  realize that they are far from God's gift to the world because I would hope that god would send a hell of a better gift.
