The ideological and political theory course is the key course to implement the fundamental task of cultivating morality and cultivating people by moving students with feelings, enlightening students with theory, and driving students with practice to achieve the effect of blending feelings and reasoning, learning and understanding, believing and using. For teachers of Ideological and political courses, it is necessary not only to keep up with the new era in teaching content, but also to constantly improve their own ability level, so as to practice the important task of spreading knowledge, spreading ideas, spreading truth, shaping soul, shaping life and shaping new people. Ideological and political teaching involves many subjects and fields, and involves the world, national conditions, the party and the people. It requires high comprehensive quality of teachers. At present, in the face of the rapidly changing world and China, and in the face of the contemporary youth known as the "network aborigines", only by constantly updating the teaching content and constantly speaking and updating can better teaching results be achieved. Only by basing on theory and taking root in practice can problems be explained clearly and thoroughly. In the ideological and political class, teachers should move students with feelings, inspire students with theory, and drive students with practice, so as to achieve the effect of blending feelings and reasoning, learning and understanding, believing and using. To teach ideological and political courses well, we should make good use of the main channel of classroom teaching. What and how to say in the classroom tests teachers' teaching ability, and it is necessary to constantly enhance the ideological, theoretical, affinity and pertinence of the curriculum. For example, in the study of classical original works and the history of Marxist development, it is advisable to start with Marx's own experience, so that students can feel Marx's personality charm of loving life, being sincere and simple, and paying attention to love and righteousness. Through the discussion in the classroom and the study outside the classroom, let the students understand Marx, a great man who stands tall and upright, and feel the truth power of Marxist theory. In the ideological and political class, knowledge is the carrier and value is the purpose. Only by guiding values in the teaching of knowledge can teachers and students improve their ideological quality and cultivate their faith through teaching activities. To teach ideological and political courses well, we should make good use of the large class of social practice. This requires ideological and political teachers to go out of the campus and into the society, go deep into the grass-roots level and participate in practice. For example, since 2019, Tongzhou District of Beijing has jointly implemented the "ten million talents gathering project" with colleges and universities in Beijing. In the fields of urban planning, industrial development and grass-roots governance, about 20 college teachers and cadres have been introduced each year for on-the-job training. With this experience, we can make the ideological and political courses more grounded. For example, when explaining the prevention, control and management of major public health emergencies, some teachers who participated in temporary work combined with grassroots experience and front-line anti epidemic stories to help students understand the scientificity and importance of the dynamic zero policy more comprehensively. To attach importance to the practicality of Ideological and political courses, it is necessary to combine the small ideological and political classes with the large social classes, and it is also necessary for teachers to take the initiative to take the "required courses" of social practice, open the classroom vision with fresh practice as the material, and guide students to be neutral and ambitious in the unity of knowledge and action. "It's a sacred achievement to be able to nourish the righteous." The ideological and political course is a course that teaches students correct ideas. Teachers of the ideological and political course should put their main responsibility and main business into guiding students to establish correct ideals and beliefs
