It is the inevitable sublimation of "deep" to explain the truth "thoroughly" and the key premise of "living". As the name suggests, the so-called "transparency" refers to transparency and thoroughness; To explain the truth "thoroughly" means to explain the profound philosophical principles clearly and thoroughly by eliminating the rough and selecting the fine, eliminating the false and preserving the true, from one to the other, from the outside to the inside, so that students can know more about the "why" and "why" and "why". The essence of Ideological and political course is to be reasonable. Whether the truth can be truly "transparent" is directly related to the realization of the essence and the image of Ideological and political course. It is the essential requirement of Ideological and political course to explain the truth thoroughly. First of all, speaking of "transparency" requires thorough theory and convincing people with reason. Ideological and political courses are about thorough and convincing Marxist principles, the truth of learning for practical use, and the truth of practicing. Only by thoroughly learning, researching and highly recognizing the ideological theories behind these truths can ideological and political teachers explain the truths clearly, enable students to truly insight into the "ideas" and "methods" behind "statements" and understand the "truth" and "reason" among "truths". Secondly, speaking of "penetration" requires the theory to be symptomatic, answer questions and dispel doubts. The theories, viewpoints and conclusions of Ideological and political teachers should be able to withstand the students' various "why" questions. We should be good at starting from a problem, thoroughly explain a point of view, bypass by analogy, and thoroughly explain the University questions, so that students can understand political, intellectual and general principles in a sincere and convincing way. Thirdly, speaking "transparent" also requires clear logic and smooth expression. If we want to persuade students, we must respect students' cognitive laws, explain the essence and development mechanism of reason with a meaningful teaching language that conforms to the characteristics of youth, is close to the reality of life, and guides students to understand "true knowledge" through "familiarity". It is a realistic need to deepen the reform and innovation of Ideological and political courses to "make sense". To explain the truth "thoroughly" is not only the proper meaning of deepening the reform and innovation of Ideological and political course, but also the key action for ideological and political course to win students and realize soul casting and education. Only by thoroughly explaining the truth can we enhance the sense of acquisition of Ideological and political courses for college students. On the contrary, specious, impractical, and seeing flowers in the fog can only be a set of false truths, small truths of talking to oneself, and empty truths of castles in the air. Naturally, the students' listening effect will be greatly reduced, and will also affect the quality and effectiveness of Ideological and Political Teaching reform and innovation. Only by thoroughly explaining the truth can we consolidate and strengthen the main ideological position of Ideological and political courses. Nowadays, the world is intertwined with the century situation, the competition between the two value systems is becoming increasingly fierce, and some wrong thoughts are surging in the society. This requires that our ideological and political courses must arouse the evil and promote the clean, establish and break through at the same time, clearly explain the "great power of the country", thoroughly explain the "general trend of the world", clarify the "road of action", educate and guide students to distinguish between right and wrong, resist wrong trends of thought, and strive to be a confident, self-improvement, reliable and promising new generation. Only by thoroughly explaining the truth can ideological and political courses better meet the needs and expectations of students' growth and development. Chinese youth in the new era are more self-confident, self-improvement, and full of speculative spirit. At the same time, it is inevitable that they will encounter ideological confusion in the aspects of ideal and reality, doctrine and problems, egoism and altruism, ego and ego, nation and the world. As a key course for building morality and cultivating people, ideological and political courses must be targeted to explain students' ideological puzzles, help students correctly understand the times and historical missions, and strive to be a new generation worthy of the important task of national rejuvenation. It is a compulsory course for ideological and political teachers to explain the truth thoroughly. For a long time, the major challenges faced by ideological and political courses are that the teaching involves "wide content", the updating speed is "fast", and the content requirements are "specialized". How to deal with these challenges and explain the truth of Ideological and political course thoroughly is a compulsory course for every qualified ideological and political course teacher. On the one hand, to explain the truth "thoroughly" not only requires the ideological and political teachers to form a consensus, but also has the ability to "thoroughly" in teaching. Only when people with ideas speak of ideas and people with beliefs speak of beliefs, can they speak clearly, profoundly and thoroughly. Ideological and political teachers should strengthen their political beliefs, overcome "skill panic", adhere to the unity of theoretical specialization and academic research, consciously improve their ability and level of "penetrating" the truth with Marxist positions, viewpoints and methods, combine the small ideological and political class with the large social class, and not only explain the philosophy but also the academic theory, and convince the students with thorough ideological theory, so as to achieve the purpose of communicating the mind and The teaching effect of enlightening wisdom, moistening heart and inspiring fighting spirit. On the other hand, we should promote the innovation of teaching methods that explain the truth thoroughly. On the one hand, we should "follow the instructions" and explain the theory clearly; We should "continue to talk" and pay attention to the context behind the truth; It is more important to pursue "speaking in front" and "leading", focus on the major practical problems and ideological puzzles that students pay attention to, flexibly use problem-based, participatory, comparative and other teaching methods, carry out targeted explanations, and win the emotional resonance of students. In addition, we should focus on superior resources and strive to build a sophisticated digital ideological and political teaching resource platform that "explains" the truth; We will continue to improve the mechanisms of teaching teams' collective lesson preparation, collective observation and evaluation of teaching, and teaching assessment and evaluation, so as to create a good teaching ecology of "penetrating" the truth.
