In the context of the digital age, ideological and political course teaching is facing challenges and opportunities, and the development of AR technology makes it possible for its innovation. This research comprehensively uses a variety of methods to elaborate on the connotation and characteristics of AR technology as well as the teaching objectives and requirements of ideological and political courses, and explores the theoretical basis for the integration of the two. Through case analysis, it shows its effectiveness in improving students’ knowledge mastery, interest stimulation, and value shaping. It constructs the online teaching mode of ideological and political courses empowered by AR technology, including resource integration, activity design, and effect evaluation; and explores offline teaching practices, such as innovative classroom applications and the expansion and deepening of practical teaching. The empirical analysis of the effectiveness of the online and offline integrated teaching shows that it has a positive impact on students’ learning, but it also faces challenges such as technology, teacher capabilities, teaching resources, and student adaptability, and corresponding strategies are proposed. The research confirms that this integrated teaching has significant advantages. Looking forward to the future, the application prospect of AR technology in ideological and political course teaching is broad, aiming to promote the high-quality development of ideological and political course teaching.
