This paper explores the integration of strengthening the consciousness of the Chinese nation community with ideological and political education in engineering major courses, an important issue in higher education reform. Strengthening the consciousness of the Chinese nation community emphasizes the unity and common progress of all ethnic groups, aiming to enhance national cohesion and harmonious social development. Ideological and political education in engineering courses incorporates core socialist values and scientific methods into professional knowledge to cultivate students' sense of social responsibility and innovation spirit. This paper proposes specific integration strategies in terms of curriculum design, practical teaching, and the combination of craftsmanship and scientific spirit. It also suggests innovative teaching methods through interactive teaching, interdisciplinary integration, and multimedia tools. Furthermore, the establishment of a scientific evaluation and feedback mechanism is recommended to ensure teaching effectiveness and to nurture innovative engineering talents with a strong sense of social responsibility and patriotism.
