摘　　要：目的:探索解决生物医学工程专业本科阶段电磁场理论与数值计算课程知识跨度大、数值计算编程入门困难等问题的教学新思路。方法:根据近5 a的教学经验,精简电磁场数值计算知识体系、丰富编程内容,精心设计规则圆域的网格剖分、电磁场正问题——有限元方法数值计算、电磁场逆问题——电阻抗断层成像3个编程实践环节,同时创造性地在课程实施中加入较短的激励反馈环节。结果:考核成绩证明了学员的编程实践环节成绩较好且兴趣较浓厚的学生理论考核成绩往往较高,呈现正相关的趋势。结论:提出的理论—实践—反馈教学模式有助于学员克服畏难情绪并建立信心,为本科阶段开设电磁场理论与数值计算课程提供了参考。Objective To explore new teaching ideas to solve the problems of large knowledge span of electromagnetic field theory and numerical calculation course and the difficulty of numerical calculation programming.Methods Based on the teaching experience in the past five years,the knowledge system of electromagnetic field numerical calculation was simplified,the programming content was enriched,and three programming practice links were carefully designed:regular circle mesh generation,finite element method numerical calculation(electromagnetic field positive problem)and electrical impedance tomography(electromagnetic field inverse problem).At the same time,a short incentive feedback link was creatively added in the course implementation.Results The examination results showed that the students who had good performances and strong interest in the programming practice link were gifted with higher theoretical examination results,and that there was a positive correlation trend between the practice and theoretical examination.Conclusion The teaching mode of integrated theory,practice and feedback is helpful for the students to overcome their fear of difficulties and build up their confidence,which provides a reference for the course of electromagnetic field theory and numerical calculation.
