Abstract: Circle communication has reshaped the communication ecology of online patriotic education discourse in colleges and universities. Consequently, the processes of discourse production, dissemination, and reception have acquired several new characteristics, including the coordination of real-time interactive feedback with discourse production, personalized information reception enabled by algorithmic precision recommendation, and the interplay between emotion-driven communication mechanisms and the stratification of value identification within circle communication. Against this backdrop, the effective transmission of mainstream values in the online sphere has become increasingly challenging. Grounded in Circle communication theory and discourse construction theory, this study analyzes the practical challenges confronting online patriotic education discourse in colleges and universities, including structural barriers to discourse reach, adaptation bottlenecks in discourse expression, and mechanism-related dilemmas in discourse feedback. Accordingly, enhancing the effectiveness of such discourse requires three interconnected approaches: adapting to segmented communication mechanisms to improve discourse reach; innovating forms of discourse presentation to strengthen its expressive capacity; and establishing an optimized feedback mechanism to enhance its transformative capacity.
