Once you are a teacher, you want to become a perfect teacher. Sadly, this is difficult. All students are different and each of them has his own learning style.
Here are two tips you must be aware of to be a better teacher for your students.
First is to be an assertive teacher. You have to understand that your students also have problems and bad days, so if one of them becomes less motivated do not argue with him, try to support him and ask him what is happening and push him to do better. Be his friend , but stay professional, help him with homework, listen to him, be willing to talk with your students about thier lives but remember who you are. Try to avoid using slang, your students will not take you seriously.
Secondly is to explain the lesson in many different ways. Be patient, and explain your material over and over again. No one was born knowing, remember you also had a teacher and he had to repeat his material for you and your classmates
