Understanding the effects of the behavior is another vital part of your preparation for dealing with that behavior. It is important to be able to point out how the behavior actually affects the teacher, classmates, and/or the learning environment in the classroom. To suggest any solution, without first identifying which areas the behavior is affecting, is useless. If you first take the time to observe the effects of the behavior in question, you'll find it much easier to pursue workable solutions designed to bring about positive and constructive change.
It should be noted that a student's behavior often affects only the teacher. Yet, if the student's behavior prevents the teacher from teaching, some changes in the behavior are necessary. Recognizing that the behavior affects only the teacher does prevent negative teacher action such as saying he or she is bothering the rest of the class.
