Nourishing Xinjiang with culture (wenhua runjiang) represents a key practice of the Party’s Xinjiang governance strategy in the educational domain in the new era, while curriculum-based ideological and political education constitutes a strategic initiative for implementing the fundamental task of fostering virtue through education. Confronted with the distinctive ideological and political education ecology and the demand for application-oriented talent cultivation in the Xinjiang region, local higher education institutions face an urgent imperative: how to construct a systematic ideological-political cultivation framework through computing curricula, with nourishing Xinjiang with culture serving as the value compass and computing courses functioning as the disciplinary vehicle. Grounded in cultural identity theory and the consciousness of the community for the Chinese nation, this study elucidates the unique role of computing education in transmitting Chinese culture and safeguarding ideological security in border regions. It proposes an integrated “value–knowledge–competence” framework. Centering on the design of instructional objectives, content restructuring, methodological innovation, and evaluation and feedback, the study transforms discipline-specific features—such as cybersecurity, artificial intelligence, digital preservation of ethnic cultures, and algorithmic ethics—into focal points for ideological and political education, and substantiates them through concrete teaching cases. Furthermore, the article constructs a safeguarding closed-loop encompassing faculty capacity building, organizational leadership, and quality evaluation, with the aim of developing a replicable and scalable system of ideological-political cultivation through computing curricula, thereby providing intellectual and talent support for the initiative of nourishing Xinjiang with culture.
