In the context of the transformation, upgrading, and sustainable and healthy development of the construction industry driven by digitization and intelligent upgrading, to cultivate versatile and comprehensive talents under new engineering construction that places greater emphasis on innovative teaching models, this paper explores how to integrate information and digital technology into the ideological and political teaching of the design principles of steel structure course, to implement the fundamental task of cultivating morality and nurturing talents. With Qiantang River Bridge (an early steel structure truss bridge connected by rivets and supervised by Mao Yisheng, former president of Beijing Jiaotong University) as the background, and Mao Yisheng spirit as the soul, Qiantang River Bridge is studied in-class and various structural design competitions are participated in after-class, such as National College Students’ Mao Yisheng Public Welfare Bridge-Small Bridge Project Design Competition, National College Students’ Structural Design Competition, National College Students’ Steel Structure Innovation Competition, and Beijing College Students’ Architectural Structure Design Competition. This not only helps to learn, practice, and inherit Mao Yisheng’s engineering education philosophy and the spirit of patriotism, science, struggle, and dedication, but also constructs an integrated teaching model that integrates learning, production, and research, achieving the penetration and integration of knowledge, ability, and value. 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.
