<p>These were great suggestions. I've not had student getting out of hand in my class with each other but I've had student upset with me. I typically don't allow students to take us off topic and every once and a while a student will get angry because I will not allow this to happen. I let them know that I am open to a discussion after class but not at that moment. When a student knows that he or she will be able to speak their piece at some point they usually settle down.</p>
