Talk to the Students
Talk with the students, not just in the classroom or school, but outside as well. Whenever you come across any student in the cafeteria or in your neighborhood grocery store, greet them. If any student has excelled in a particular sport or event, appreciate him or her. Praise their sincere efforts and tell them how they should go on with it. This will make the students feel that you are close to them and you understand them, the result of which will be obviously seen in the classroom.
