A recent survey examining student learning in the college classroom found disruptive student behavior to be a major learning inhibitor. Compounding this is the realization that most college faculty are ill prepared to handle this problem. This article discusses the results of the survey as well as identifies the various types of disruptive behavior that college faculty are likely to find. Some behaviors are covert (sleeping, arriving to class late, etc.) while others are more apparent and overt (talking during class and using cellular phones). Potential solutions to the problem are also discussed. Perhaps most important, however, is the impact disruptive students can have on student retention. An unsatisfactory learning environment has been linked to students leaving a university early. It is therefore imperative that faculty and administrators alike be both proactive and reactive here.
