摘要:通过对数学物理方程课程教学现象中存在的问题进行研究分析,针对学时短,内容多,数学推导复杂,学生兴趣不高等问题提出了问题驱动下的教学策略,主要以热传导方程内容进行教学设计,通过层层设问来进行数学建模;运用分离变量法对金属棒的定解问题进行求解,并对结果可视化来进行分析,从而得出温度的衰减规律和稳态特征;并引入电气工程中功率器件的散热案例,体会理论与工程的融合。
Abstract:This study investigates the existing problems in teaching the course of Mathematical Physics Equations, such as limited class hours, excessive content, complex mathematical derivations, and low student interest. To address these issues, a problem-driven teaching strategy is proposed. Using the heat conduction equation as an example, the instructional design guides students through step-by-step questioning to perform mathematical modeling. The separation of variables method is applied to solve the initial-boundary value problem of a metal rod, and the results are visualized for analysis, revealing the decay law of temperature and steady-state characteristics. Furthermore, a case study on heat dissipation in power devices from electrical engineering is introduced to illustrate the integration of theory with engineering practice.
