Small disruptions handled early rarely become big ones. A calm, private word after class is usually more effective than a public confrontation, which can escalate and cost you the room. Address the behavior, not the person, and restate the expectation.

For tense moments, including heated disagreement on a sensitive topic, slow the pace, acknowledge the tension, and refocus on the question and the ground rules you set. You do not have to resolve everything yourself. Know your campus resources, such as the dean of students, counseling, and accessibility services, and involve them when a situation is beyond a classroom fix. Managing an online class follows the same principles, with clear written norms doing more of the work.
