Personality traits has much significance in the prediction of human behavior in various situations. Personality traits affect a person's behavior. Usually personality traits do not change, and they are reflected in a person's behavior in various situations. Teaching, like any other profession, requires specific traits, skills and personal abilities, a basis of extensive, professional knowledge and the appropriate perceptions and thinking. Teachers' personality traits play an important role in their work. There are correlations between people's personality traits and their behavior in various situations. Thinking styles constitute a central aspect of one's personality, whereas other researchers claim that personality traits and thinking styles overlap somewhat, but that each of them provides a unique contribution, with clear structures characterizing them. Personality traits explain a high percentage of the diversity in thinking styles and explain the variations in thinking styles in higher percentages.
