The study of approches is the inherent requirement for the discipline attribute of ideological and political education,meanwhile,it is the research area with the practical significance. Approach is not only the sterotype of the theory of ideological and political education, but also the generalization of the concrete experience of ideological and political education, and thus it constructs the tie and the bridge connecting the theory and practice of ideological and political education, which forms the inherent intergrowth orgnic whole containing the educator,the education target, the education object and education enviroment so as to decide the practics system of "subjective input" and "selective activation".In terms of subjectivity,subject sequential difference is the premise to prmote the approach develpoment of ideological and political education. As a kind of educational product, subject sequential difference is the comparison between the discourse right of the educator and the subectivity degree of the education target, which not only directly contained in the quality , the structure and the personality of the educator contingent, but also embodied in the essece of education targets\'self-integration. With the development of economy and the society and the improvement of the subjectivity, the difference of the objects\'expanding ablity and the impact of the factor of enviroment go in depth, thus it corners ideological and political education for the unversity students into the temporary difficult position triggered by the change in education subjective sequential difference,accompanied by the temporary ignorance of the approach discourse right of the transformation period, presenting the obvious "approach dislocation". We should follow the approach structure and the logical of the mechanism to seek the practical solution, that is, we should not only give full play to the resource advantage of ideological and political education, concentracting on developing the subjectivity of ideological and political education subject, but also expand the social public education resources, building the approach to ideological and political education merged in the social life, by improving the socialization of the approach and culture attribute so as to lead and confrom the impact of the social life and expand the new advantages of ideological and political education.
