With China paying more and more attention to the quality education of students' all-round development, the research on hidden education in ideological and political education has been paid more and more attention and achieved certain results. The formation of people's ideological morality, moral sentiment, ideals and beliefs is a very complicated process. Often subject to the "soft constraints" and influence of its environment and atmosphere, that is, the so-called "learning without learning." Implicit ideological and political education is an educational method in which the potential curriculum theory is consciously used in the process of ideological and political education, and the educational content is hidden in the created educational situation without trace. By adopting the forms of "detour" and "infiltration", the educated can unconsciously acquire some thoughts, experiences or practices and internalize them into their own behavior norms.

First of all, give play to teachers' exemplary role and role model. Teachers should not only teach, but also educate people, and give full play to teachers' recessive ideological and political education function. Teachers of ideological and political courses are like a mirror of life in the minds of college students, and their personal charm and teachers' morality have a direct or indirect influence on college students' attitude towards things and life. Moral education is not only the imparting of knowledge, but also the cultivation of personality and virtue. So listen to the hidden educational methods. Teachers' charming personality charm and academic spirit are often the focus of students' imitation. Teachers and classmates are ordinary people that college students meet at school. Their "personality and educational style" will show corresponding attitudes towards words, behaviors and things in students. As an influence-oriented, invisible and hidden education, the hidden education method is not realized by students themselves. In a subtle and hidden way, we can effectively resolve the subconscious consciousness of teenagers in the rebellious period against moral preaching, and use the methods of culture, system, management and hidden courses to subtly touch, shock and move students consciously or unconsciously, so as to achieve the purpose of improving the quality of education.

Secondly, implicit education is a useful supplement to the original explicit education mode, which can infiltrate political thoughts through family education, situational education and extracurricular activities. Especially in the education of political values, we should pay attention to creating a good educational environment atmosphere, so that students can unconsciously understand and internalize their own political system. Implicit education seems to have no clear goal, and its goal is often achieved through students' activities. With the help of various external conditions, it acts on the internal psychological process of individuals and forms good moral behavior. The student activities mentioned here mainly include: First, colorful campus activities. Organizations that carry out student club activities, student art activities, sports competitions, and various interest activities. Second, various forms of social practice. Such as students' summer practice and various volunteer activities. Third, the combination of community activities and family education activities with school moral education. No matter what kind of student activities, organizers must have clear educational goals and take corresponding measures to promote the realization of educational goals. For the educated, the purpose of education should not be too clear, and students should explore and experience in their own practice to prevent it from becoming an explicit education. Only when students are trained in a complex environment and tested in a complex life practice can they really enhance their resistance and form their inner and stable ideological and moral quality healthily. Therefore, it can cultivate students' thoughts and feelings, recast students' intelligent structure, and make students' ideological and moral qualities change imperceptibly.

Third, make full use of the functions of modern media and smart phones to strengthen the ideological influence on students. In the era of the marriage of information and high technology, university education should also make full use of these modern means. On the one hand, with the help of network platform, computer simulation technology and simulation sand table, the scene, simulation and visualization of classroom teaching can be realized, the teaching information of media can be expanded, the teaching content can be updated, and the educational efficiency can be improved. On the other hand, we can use QQ, BBS, WeChat, Weibo and other new media tools commonly used by college students to implement hidden education in the field of ideological and political education and strengthen college students' self-identity, cultural identity and social identity.

In short, ideological and political teachers in colleges and universities should not only attach importance to explicit education, but also actively guide and organize college students to carry out various healthy and beneficial hidden education activities. We should actively create conditions to carry out various social practice activities inside and outside the school. Practice has proved that many colleges and universities consciously organize college students to go out of campus and carry out various forms of social practice activities and youth volunteer activities, which has received obvious educational effects. Many college students have broadened their horizons, gained a deeper understanding of China's national conditions and current situation, and their ideas have also undergone positive changes. It can be seen that the process of college students' conscious participation in social practice is not only the process of integrating moral education workers with college students' ideas and values, but also an excellent opportunity for implicit education.
