This document provides advice for managing groups in the classroom and dealing with difficult situations. It recommends being assertive by communicating clearly with gestures and active listening. When a difficult situation arises, teachers should listen to their tone of voice, verify their physical position in relation to students from 1 meter away in their line of vision, be aware of hand positions without crossing arms or in pockets, and phrase requests carefully and respectfully to students. The overall goal is to promote students' self-esteem and confidence through coherent and respectful communication.
