Establish clear-cut classroom rules. Describe in clear terms what you expect from your students. Be as specific as possible. A generalized rule such as "Be punctual" doesn't carry as much weight as "Be in class by 8.30 a.m. sharp," which is clear, thorough and informative.
Set consequences for violating rules. This can range from a warning to dismissal from class to suspension, depending on the seriousness of the violation. Educate yourself about your college's discipline policies and punishment for transgressions. Incorporate them into your consequence list. Communicate to your students about your rules and consequences. Implement consequences each time a student violates rules.
Investigate the reasons behind the consistent misbehavior of a student. Arrange with your college counselor and discipline manager to have an informal discussion with the student. Provide them with details of your classroom rules and consequences and the student's violations. This approach provides insight into any underlying problem the student has and provides the counselor's help or external expertise to address it. Learn from the counselor and discipline manager if there are any steps you need to take to help the student stick to expected behaviors.
Keep a record of all the violations made by students. This documentation provides evidence if more stringent action, such as suspension, is needed if the student makes repeated violations. A simple way to document is to send an email to the student detailing his misbehavior and the action taken by you each time a violation occurs.
Treat your students with respect. Listen to what they have to say, respond to their queries without ridiculing or patronizing, and converse using decent vocabulary. Students are most likely to mirror your behavior.
