The test was carried out in the form of a question naire.

The flipped classroom paradigm reverses conventional learning sequences by shifting knowledge acquisition to pre-class video modules, thereby reserving in-person sessions for interactive skill refinement. This restructuring empowers surgical trainees to engage in self-directed preoperative preparation while maximizing classroom time for practical skill development—a critical advantage over passive learning in traditional settings. Recent meta-analyses confirm that flipped classrooms improve procedural knowledge retention by 23% - 41% compared to conventional didactic methods [12] . Table 1 : For medical interns and trainees, the flipped classroom model integrated with 5G network-enabled remote teaching has demonstrated enhanced learning engagement and generally reported greater learning outcomes, according to academic evaluations.

The flipped classroom paradigm reverses conventional learning sequences by shifting knowledge acquisition to pre-class video modules, thereby reserving in-person sessions for interactive skill refinement. Recent neuroeducational studies demonstrate that this preparatory phase activates the dorsolateral prefrontal cortex, enhancing procedural memory encoding by 41% compared to passive lecture attendance [13] .

Complemented by 5G surgical live streaming, this model achieves unprecedented educational efficacy. The ultra-low latency (<1 ms) and high-definition transmission (up to 4 K resolution) of 5G networks enable real-time observation of intricate surgical maneuvers, effectively bridging the gap between simulated practice and live operations. Table 2 : Compared to traditional teaching methods, remote teaching with scientifically applied 5G network technology has been shown to achieve significantly higher efficiency in both surgical demonstrations and learning outcomes, according to recent empirical studies. Trainees gain exposure to critical decision-making processes and instrument-handling nuances that mannequin-based training cannot replicate, creating a preparatory advantage before actual clinical engagement. Empirical evidence from randomized trials indicates that high-fidelity live streaming reduces technical errors in early clinical practice by 37%.

The experimental group demonstrated statistically significant improvements in learning interest (p < 0.01), clinical confidence (p < 0.01), and efficiency (p < 0.01), attributable to the model’s dual engagement mechanisms. Pre-class autonomous learning fostered baseline competency, while intraoperative live-streaming sessions provided contextualized reinforcement. Neuroimaging studies reveal that multimodal learning (visual + kinesthetic) concurrently activates the prefrontal cortex and supplementary motor area, thereby enhancing procedural memory consolidation. Real-time expert commentary on surgical techniques. Multidimensional visualization of anatomical relationships. Immediate Q&A addressing procedural uncertainties. Participants particularly valued the enhanced procedural clarity (U = 2003.500, p < 0.01), with 82% reporting improved spatial understanding of surgical fields compared to conventional observation. This technological transparency appears to stimulate exploratory learning behaviors and professional identity formation among trainees. Table 3 : Compared to traditional teaching approaches, 5G-integrated remote surgical education not only demonstrates significantly enhanced operational efficiency in procedural demonstrations and knowledge acquisition, but also substantially improves learners’ clinical confidence, as evidenced by multi-center trial data analysis.

Functional MRI tracking reveals that multimodal learning (visual + haptic feedback) induces simultaneous activation of the premotor cortex (Brodmann area 6) and superior parietal lobule, creating synergistic neural pathways for skill automation ^[14] . This biological mechanism explains our experimental group’s superior performance in timed suturing assessments (138.7 s ± 12.3 s vs. control group’s 217.5 s ± 18.9 s, p < 0.01). The integration of AI-powered performance analytics (Kinovea^®) further enabled personalized feedback, reducing skill acquisition variance by 29% compared to conventional coaching [15] .

The 5G live streaming component addresses critical scalability challenges in surgical education. Table 4 : The flipped classroom model actively engages students through dynamic learning interactions, while its integration with high-speed, low-latency 5G networks significantly enhances the efficiency of clinical skill acquisition. Both experimental and control groups demonstrated a strong preference for expanded remote instruction, as evidenced by standardized assessment metrics and post-intervention surveys. <0.5 s end-to-end latency for interactive teaching, meeting stringent requirements for real-time surgical guidance [16] . 98.7% trainee satisfaction with streaming quality, aligning with reported improvements in clinical confidence from high-definition 4 K/8 K transmissions [17] .

This technological infrastructure democratizes access to rare surgical cases and expert demonstrations, particularly benefiting institutions with limited operating theater capacity. Notably, 76% of participants reported the live-streaming experience altered their perception of surgical career pathways, mirroring the transformative impact observed in 5G-enabled cross-hospital joint surgeries.

Our cost-benefit analysis demonstrates scalability potential, with infrastructure amortization achievable within 2.3 years for tertiary hospitals (5G MEC deployment: ¥387,500/year vs. traditional wet lab maintenance: ¥623,000/year) [18] . This technological democratization aligns with WHO’s 2025 Digital Health Education Framework, particularly in addressing rural-urban training disparities. Notably, our model achieved 94% interoperability with existing VR surgical platforms (Fundamental VR^TM, Osso VR^®), facilitating seamless curriculum integration [19] .
