Abstract: The teaching of art design major in colleges and universities is mostly influenced by the western education system. In the teaching of design sketch, teachers should guide students to discover the beauty of Chinese traditional culture, so as to realize cultural identification. Moreover, teachers should fully tap the ideological and political education resources in the design sketch course and make students' creative practice be linked with economic and social development, so as to stimulate students' cultural confidence. In addition, teachers should also reform teaching method and evaluation method and achieve the organic integration of professional course teaching and ideological and political teaching, so as to improve teaching quality and effectiveness.
