The behavior of the disruptive student may or may not include elements of disturbed behavior, but always negatively impacts those around him/her. The disruptive student makes it difficult for routine work or teaching to occur. Disruptive behavior includes any intentional interference with the normal classroom procedure or the presentation of the instructor and/or other students. Signs are:
- Behavior which persistently interferes with effective class management
- Frequent or high levels of irritable, unruly, abrasive, or aggressive behavior, including argumentative questioning or monopolizing of classroom discussion.
- Bizarre behavior that is obviously inappropriate for the situation (e.g., talking to something/someone that is not present)
- Questioning an instructor's authority in front of the class.
