Be patient, understanding, and emphatic! It is important to understand that changing some behaviors in children can take time. Sometimes more time than one school year.
It is essential to have a relationship with the students and their parents. Having regular communication with parents can help you see into the students’ home environment, which very likely will give you a better understanding of their behaviors.
The students’ parents must be your allies, not your enemies. You will be surprised how some parents can open up to you if you demonstrate that you genuinely care for their children.
