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. They can make certain rules and inform the class to take precautions. Informing the students that there are things to watch out for will only help them. My beliefs on education have to do with what kind of teacher I want to be. I want to be a teacher that helps them to understand concepts.
