The advent of Beyond 5G (B5G) communication technologies and intelligent sensing devices has introduced new paradigms in online education, enabling real-time, interactive, and high-fidelity remote instruction. This study proposes a novel live-streaming teaching model for college English writing courses that leverages B5G networks and smart IoT devices to integrate Civic and Political Education (CPE) into writing pedagogy. The framework combines a multimodal resource repository, intelligent classroom feedback mechanisms, and real-time student behavior monitoring to support immersive instruction and value leadership. By systematically modeling instructional quality—including audio clarity, interaction latency, feedback efficiency, and learning concentration—quantitative assessments under different network conditions demonstrate significant advantages of the B5G environment in reducing latency (30 ms), improving knowledge delivery integrity (99%), and enhancing teaching effectiveness scores (0.95). Pedagogically, the model incorporates writing tasks centered on cultural identity, civic responsibility, and ethical reflection, promoting student engagement through pre-writing discussions, live critiques, and iterative feedback. Experimental data collected from 50 university students indicate improved writing performance, increased peer interaction, and higher satisfaction across technical, service, and teaching dimensions.
