This study focuses on the deepening paths of ideological and political construction of professional courses in higher vocational colleges, taking the layout design course of the digital media technology major as the research object, and explores the integration mechanism of excellent traditional Chinese culture and professional teaching. The curriculum’s ideological and political reform is advanced through three major measures: Reconstructing the role of teachers, innovating teaching methods, and building a cultural infiltration system. Combined with the three-dimensional assessment mechanism of “professional + culture + value” and the transformation of teaching achievements into competitions, it breaks through the limitations of traditional skill training and systematically solves the problems of formalization tendency and insufficient value guidance existing in the practice of curriculum ideology and politics. It responds to the era proposition of “promoting the creative transformation of excellent traditional Chinese culture,” and provides an operable solution for higher vocational colleges to break the predicament of “emphasizing skills while neglecting culture.”
