Almost every teacher has experienced the frustration of trying to manage an unruly student. In all likelihood, neither will happen. There are laws against killing students, and unless your life has been threatened, you will probably see the student quickly returned to your classroom. It is important for teachers to step back and look at the big picture.
Most children are good and come to school wanting to learn.
There are always a few students who will test a teacher just to see what the limits are. A good discipline system and parental involvement can usually take care of these problems. A very small number of students are so disruptive that removal from the classroom is finally the only solution. If these students are allowed to continue to interfere with the teacher's ability to communicate with the other students, little learning can take place. Good classroom discipline is important.
