Abstract: The people on the edge of classroom teaching are a special group. They are free in the classroom teaching activities and can't get comprehensive development through the normal classroom teaching. The edge state is developmental, behavior is concealment and classroom performance has a retreat. Their psychological barriers, the orientation of educational value of teachers and family environment caused formation of this phenomenon. The theory of Noddings Caring Education regarded caring as a prime goal, dedicated to training for caring teachers and students, advocating the establishment of caring relationship, which play an important role in moral education. Based on this theory, starting from the change of two main parties, we could establish a caring relationship by means of example, communication, practice, to keep continuity of caring relationship in purpose, location, individual and course to resolve the marginalized people.
