Talk to him as a person. Know the student's face and name, but also his nickname, if he has one. Always look him directly in the eye when speaking to him, so that he knows that he has your respect and attention.
Listen to him. If a student is speaking, pay attention and look directly at him as much as possible, so as not to potentially make him feel like he's not being respected. If possible, don't interrupt the student; let him say what he wants to say, then respond or engage him in conversation without being condescending.
Demonstrate respect through positive reinforcement. Students can sometimes be encouraged through words and gestures to feel better about themselves. In classrooms, positive reinforcement can take various forms, such as telling a student he is doing a good job or placing banners and signs in the classroom with positive messages that make students feel like they're respected.
Set rules and limits for personal conduct. In a school and classroom, students need rules and discipline to protect them from themselves or other students. A lack of rules can sometimes make a student think he isn't respected enough for his well-being to to be considered. A school or class where students are allowed to run amok can contribute to students' feelings of disrespect or lack of self-worth.
