Exploration and practice of teaching college English writing webcast classes based on B5G and sensing device support under the threshold of intelligent courses: analyzing the physical and physiological impacts on learners

The post-fifth-generation communication (B5G) and Internet of Things (IoT) environments have not only revolutionized the technological aspects of live English instruction in educational technology but also hold potential implications for the physical and physiological experiences of students during learning. In this research, a mathematical modeling approach based on B5G-IoT is employed to assess the impact on teaching efficacy. Through a set of constructed mathematical formulas, the influence of live broadcasting is statistically examined in a number of areas, including network flexibility, interactive delay, audio and visual clarity, and transmission quality, by building a set of mathematical formulas. The experimental design compares live English teaching effects under 4G, 5G, and B5G network conditions, collecting key indicators such as video clarity, audio signal-to-noise ratio, interactive delay, content delivery completeness, and learning concentration. Results demonstrate that in the B5G environment, video quality achieves 4 K resolution using H.266/VVC codecs, the audio signal-to-noise ratio improves to 30 dB through real-time noise cancellation algorithms, and interaction delay is reduced to less than 30 ms by leveraging ultra-reliable low-latency communication (URLLC) not only foster efficient teacher-student exchanges and a seamless teaching process but also have consequences for students’ physical states. For instance, the improved visual and auditory quality may reduce the strain on students’ eyes and ears, which in turn could affect their overall physical comfort and ability to maintain focus. Additionally, the reduction in interaction delay might lead to more natural and less fatiguing postural adjustments and muscle movements as students interact with the teaching materials. The enhanced reliability and scalability of the B5G network, ensuring 98% knowledge point delivery completeness, can potentially minimize the physical and mental stress associated with disrupted or incomplete learning experiences. This, in turn, may have a positive impact on students’ concentration and active participation in the classroom. By comprehensively considering these aspects, this detailed exploration of B5G and IoT technology applications and implementations offers a more profound understanding of their role in enhancing live English teaching and the associated physical and physiological aspects of student learning.
