To raise the qualities of the teachers is a matter of great importance in present education reform. It is only through self-education that teachers' qualities can be raised, because self-education is the basic necessity for different kinds of education to be brought into play. The reflecations can link up "the theory that the teachers propose" and "the theory that the teachers apply", and promote the change of teachers from the experienced to the learned. Thus the reflection is of great significance to the teachers'self-education and the teacher should do reflections consciously.
