The biggest problem in the middle/high school years is the student's overall tolerance with inappropriate behavior. In an average class there may be one to three students that are behavior problems and are not interested in learning or doing the work. They talk out in class, they make fun of other students, they distract other students and the teacher while learning should be going on. Teachers are equipped to deal with these distractions. The larger problem is the reaction of the class to these students. Often the other students will laugh, begin talking, lose focus or encourage more inappropriate behavior. This adds to the time away from covering the material the teacher needs to go over. Instead, if students realized that these peers were detracting from their education and chose to ignore them or gave them some form of negative reaction, perhaps the distractions would happen less. It is up to each, individual student what they take from their high school experience. Yes, teachers make a difference to an extent, but in the end it will be 'your' time and 'your' effort that will bring about the result you want. So, the biggest thing you can do to make your high school a better place would be to take charge of your education and see it as your job, for the time being, getting out of it what you put into it.
