Talk to the student and see what is occurring in the student's life that is causing this problematic behavior. Sometimes, you will discover that the student has a parent serving in the armed forces in Iraq or some other life changing event is occurring in the student's life.
Other times, you will discover that the student is in desperate need of attention and is acting out at school as there has been a recent addition to the family or the student's mother has remarried. So, the student feels the need to get attention at school, which as his behavior is being reported to the parent, the student is getting negative attention at home as well.
In these situations, the student may be open to talking about this problem with you, the teacher, or if the teacher is uncomfortable hearing the personal life of this student, a teacher should send the student to his/her counselor so that the student can get the attention that he or she needs.
Generally, if a student is misbehaving, there is a deeper reason that accounts for the problematic behavior.
