Denise, try to not focus so much on their age and focus more on their learning habits and preferences. Have you engaged in any classroom discussions about your concerns with respect to their behavior in your class? What are the consequences for your students if they leave your class with little or no knowledge of your subject matter? May be a good time to make sure they understand that the disruptions caused by their lack of professionalism is taking away from their ability to receive the knowledge they need to move forward. If your subject matter will be required by other classes or be a topic of importance during the interview process you may want to bring this information forward and help them understand why they should take more interest in what you have to share.
