As an important task of “establishing morality and cultivating people”, teachers must improve their ideological and political quality. The curriculum ideological and political ability of professional course teachers refers to accurately discovering and highlighting the “ideological and political elements” contained in them on the basis of subject knowledge, so that the implicit educational function of professional disciplines can be fully played, so as to achieve the internal unity of “knowledge transfer and value guidance”. Based on the artistic characteristics and teaching characteristics of design majors, this paper analyzes the current situation of ideological and political teaching carried out by teachers of design majors, and proposes ways to strengthen teachers’ awareness and ability of educating people.
