In the context of achieving the transformation and upgrading of the construction industry and sustainable as well as the healthy development driven by digitization and intelligent upgrading. And in order to target the cultivation of versatile and comprehensive talents, with greater emphasis on the new engineering construction that places innovative teaching models, to implement the fundamental task of "cultivating morality and cultivating talents". Moreover, on the basis of the study to integrate information and digital technology into the ideological and political teaching of the course of "Design Principle of Steel Structure". Therefore, based on the course of the steel structure “Qiantang River Bridge” (supervised by Prof. Yisheng Mao, former president of Beijing Jiaotong University, and an early steel structure truss bridge connected by rivets) as the background. With Yisheng Mao's spirit as the soul, to enable contemporary college students to strengthen their practice by studying the Qiantang River Bridge in-class and participating in various structural design competitions after-class, such as the National College Students' "Mao Yisheng Public Welfare Bridge Small Bridge Project" Design Competition, the National College Students' Structural Design Competition, the National College Students' Steel Structure Innovation Competition, and the Beijing College Students' Architectural Structure Design Competition. To further accompolish the goal of learn, practice, and inherit Yisheng Mao's engineering education philosophy and the spirit of "patriotism, science, struggle, and dedication", the integrated teaching model of learning, production and research has been built to realize the penetration and integration of knowledge, ability and value. All in all, in the research and practice of ideological and political education in courses, a closed-loop connotation ideological and political education system has been constructed, and a set of immersive practical models of ideological and political education in courses have been condensed, to final achieve the overall goal of mastering knowledge, cultivating abilities, training thinking, and shaping value. The research results of comprehensive scientific evaluation and continuous improvement model, the integration of information technology into classroom teaching and the measures of teaching ability improvement can provide references for the reform of ideological and political teaching model of similar courses.
