During my class today we were discussing different situations of how to deal with students who misbehave during such things as presentations, field trips or school dances. If a teacher decides that the student(s) should stay behind, then whose responsibility is it to supervise this person(s)?  When it gets to the point where one or more are disturbing the class what is the best action to take? Should the child be excluded and not be able to participate? Should the field trip be canceled all together and ruin it for everyone? What strategies could a teacher take so that the student(s) are able to join the class but at the same time understand that their behavior is not acceptable? I am looking for your input on strategies that work in your classroom.
