Show mutual respect. Do not yell, shout or use any bad languages in the classroom. Call each student by his name and recognize each student's performance. Even at the most annoying or frustrating moments, breathe deeply and keep your temper. Try to use humor to correct students' bad behavior. Respect each person in the classroom but do not show any favoritism. When students feel that they are respected, they will do the same to you and everyone else in the classroom.
Be prepared for each lesson. Do all necessary preparation work for your classes. Grade all papers and return them to your students the following class or at your earliest convenience. Your biggest asset is your knowledge. When you are not prepared to teach a lesson, students notice and will start misbehaving. To improve student-teacher relationship, students also need to respect your presence. The best way to build up your authority is by demonstrating your expertise in the classroom.
Engage students with in-class exercises and games. Prepare fun exercises that allow your students to loosen up and have fun while they are learning the material. During in-class exercise, you have opportunities to approach students individually and learn about them. Students will also start to like you and your class.
Be available to talk to students. Invite students to visit you during your office hours for homework help or personal guidance. Encourage them to stay after school for extracurricular activities that you supervise. Some students are more shy than others. Observe students' behavior and offer encouragement verbally or in writing.
