Abstract: This paper takes “Pb-Sn binary metal phase diagram” as a case study in Physical Chemistry Experiment to illustrate the integration of ideological and political education within the “Cognition-Learning-Practice-Reflection” framework. The course design seamlessly incorporates ideological and political elements into pre-class preview and perception, in-class practice and exploration, and post-class reflection and expansion. Blended teaching practices are implemented through the recording of instructional videos, the development of an online learning platform, the enhancement of evaluation and feedback systems, and the creation of spaces for innovative exchange. These efforts aim to achieve the holistic educational goals of “knowledge acquisition, skill development, and value shaping”. As a result, students are encouraged to build up cultural confidence, foster patriotic sentiment, enhance scientific literacy, and strengthen innovation consciousness, ultimately promoting comprehensive development.

Key words: Metal phase diagram, Course ideological and political education, Blended teaching, Scientific spirit, Critical thinking, Innovation awareness
