Abstract: Curriculum integrated with ideological and political education is an important approach for moral education in Chinese higher education. In the context of establishing first-class undergraduate majors, the implementation of ideological and political construction in professional introductory courses is essential for achieving the "Trinity" model of talent cultivation. This paper focus on the ideological and political teaching construction in the introductory course of Applied Chemistry, analyzing the current teaching status and its necessity. Positioned to cultivate application-oriented undergraduate talents and aligned with the graduation requirements of engineering education accreditation, this study delves into the “134” ideological and political teaching model. It explores four key dimensions: the teaching content of introductory courses, ideological and political elements, teaching methods, and teaching evaluation. We have reconstructed the teaching content to include six themes, embedding the ideological threads of “chemical spirit, craftsman spirit, and national spirit.” This approach employs diverse methods to seamlessly integrate moral and intellectual education, aiding students in objectively understanding chemical engineering concepts. Evaluation data indicates that the “134” model significantly enhances the educational quality and effectiveness of the professional introduction, fostering a comprehensive “Trinity” curriculum system and contributing to the development of elite undergraduate programs.
