Abstract: Subject-education puts the penetrative education concept into practice, and strengthens the pertinence and effectiveness of ideological education. Ideological and political education at colleges should emphasize on both student subject and value orientation, and pay attention to not only education efficiency but also its sustainable development. In order to guarantee the actual effect of ideological and political education, a whole subject-education system is necessary which includes all college study stages, and all education spots and surfaces in a criss-cross structure, where we can crosswise design education themes according to students developing rules and features, and length-ways arrange education themes based on social reality, meanwhile, we are also able to determine education themes judged by the main content of ideological and political education on each surface, and consider education themes in the light of especial student groups and special problems on every spot
