Abstract: Based on multiple rounds of teaching practice in the general education course “fluid mechanics in daily life”, this paper examines curriculum design, teaching implementation, and continuous improvement of fluid mechanics general education courses from three dimensions. Guided by the core principles of “fresh, fun, and friendly” learning, the course employs multimedia case studies, interactive teaching methods, and interdisciplinary applications to explore fluid mechanics phenomena in daily life. It integrates multimedia resources, optimizing the learning experience via online-offline hybrid interactions. The attractiveness and teaching quality of the course have grown steadily over the years, effectively enhancing students' scientific literacy and humanistic perspectives, thereby offering practical references for general education reform.
