Abstract: To address the challenges in the ideological and political education of instrumental analysis courses, such as the lack of clear guiding principles, insufficient integration of ideological elements within course content, and difficulties in achieving effective educational outcomes, a three-step progressive model for course-based ideological and political education has been developed. Firstly, by aligning the specific characteristics of the course, a coherent ideological and political education framework centered around the principles of truth-seeking, practicality, and innovation is established. Then, the integration points of Ideological and political education in the course have been excavated through the layout of two dimensions of explicit knowledge and implicit values. thirdly, by means of knowledge crowdfunding, group discussion and project-based tasks, the ideological and political education of the course has been effectively promoted into the brain and heart, and finally formed a three-step and advanced ideological and political education mode that can be copied and easily promoted. At present, it has been successfully implemented in over 20 universities and several primary and secondary schools in Gansu Province and beyond.
