The document provides advice for handling different classroom management situations:
1) For a boasting student undermining others, address it privately by explaining how it affects group dynamics and confidence.
2) A disrespectful male student told a female lecturer "women don't teach men," she should assert her authority as the teacher while also addressing cultural differences respectfully.
3) When a student rudely called the lesson "crap," the lecturer should deal with it firmly while still building rapport, perhaps by discussing expectations of respect and how to provide constructive feedback.
