Traditional college physics teaching mostly deals with single physical fields, which is convenient for basic knowledge instruction but tends to fragment the inherent connections among physical phenomena, making it inconsistent with the real physical picture of complex systems in modern engineering practice. Multi‑physics coupling studied in this paper focuses on the mutual influence and synergistic interaction of multiple physical fields—including thermal, stress, electromagnetic, and fluid fields—in space and time, representing a frontier and focus of current and future scientific research and engineering design. From the perspective of multi‑physics coupling, this paper combines the current situation of college physics teaching and proposes innovative teaching strategies. It aims to effectively break disciplinary barriers, cultivate students’ systematic physical thinking, and genuinely integrate the concept of multi‑physics coupling into all links of college physics teaching through comprehensive reform and practice. These efforts will greatly enhance students’ ability to analyze and solve complex practical problems, and ultimately cultivate more engineering and technological talents with interdisciplinary literacy and innovative competence.
