This question is for both teachers and not teachers:
Assume that you have a naughty child or teenager in your class, keep laughing and throwing jokes. What are the procedures that you would take to solve such a problem that really distracts you and distracts the students' attention and accordingly hinder your lesson to go on smoothly. For me, I find it an unhealthy way to use threatening (by reducing marks or any other threat) or worst violence. Though thankfully I did not face a lot of this type of students but when I was put in such a sit, I would just throw a look of the I DID NOT EXPECT THIS FROM you sort! The good thing is that it works most of the time cuz a student feel that he was highly esteemed but he ruined his pic! If that doesn't work I would ask him to pass by me to discuss his behavior . I've just put my steps in the long way of teaching , I'm still have more to learn. That's why I'm interested in your theories and experiences .
