As a teacher, I feel that it is most important to be patient. My grandfather has told me ever since I was a little girl that patience is a virtue. I understand that now. To be understanding and patient will make it easier on everyone, including the teacher. Teachers should not come across as if they know everything.
Students learn from the teacher and the teacher learns from the class.
One more important quality and best teaching practice would be willing to go that extra mile. As a teacher you should want to help them do well. Letting the students know that you care and are there if they need you is a wonderful characteristic. Safe environments are important too. Teachers can create this atmosphere by starting with their room.
