Sport is a valued human practice, concerned with its origin of play, its own goals and traditions. Summing up the formal characteristics of sport, we might call it a free activity standing outside ”ordinary” life. It proceeds according to fixed rules and in an orderly manner. Besides, there is a link between spirit and sport. Since sport can make a significant contribution to moral education, the role of the teacher of sports should be regarded as an enlightened leader of students' character development. But the place of sport in relation to moral education and the curriculum has been neglected in schools for a long time because of the prejudices to sports. This paper aims to explore the importance of sports to moral education and the role of the teachers who teach sports. In the final section, an example is explicated to show how a high school teacher who teaches sport integrates sport experience and moral education.
