skills that a teacher should have Having good knowledge is obviously an essential skill of a teacher. Their knowledge must be very deep because they have to answer all types of questions that their students could ask. But is it enough? Many people suppose that a good teacher should be patient. They can not get angry easily. When a child makes some mistakes, we can not insult or criticize him in public because it would create a psychological problem for him. Moreover, an excellent teacher should be friendly. They should behave like a friend for their students. In this way, teenagers can tell her any problems. So, it is an advantage to avoid children's psychological problems because sometimes they do not like to talk to others about their problems. So it is fundamental that someone listen to them and suggest how to face these issues. In addition, teachers should be impartial. They should give an equal importance to every student whether they are rich or poor, black or white. They should treat them the same way even if a student is disabled. To sum up, I believe a perfect teacher should have not only good knowledge, but also patience, friendliness and the ability to be impartial.
