摘要
教学方法改革与创新是提高新工科课程教学质量的有力举措。针对新工科专业课程电磁波与天线课程理论性强、公式繁杂的特点,该文着眼提高课堂教学效果,激发学生学习动力,提出“虚实结合”的多元融合教学法。该文分析课程教学现状,探讨“虚实结合”教学方法改革与创新的途径,并对“虚实结合”的教学案例进行分析。教学实践表明,在“虚”的方面,引入Matlab和HFSS软件对抽象概念虚拟仿真,可以让电磁波的场特性形象化;在“实”的方面,采用小型化电磁场演示仪和微波试验箱,以实物形态在课堂演示,让“抽象难懂”的理论知识具体化,可有效推动学生理解和掌握电磁波从发射、传播到接收的全系统的知识,提高学生在电磁工程方面的实践创新能力,近几年学生也在国家和校级科技创新竞赛活动中取得优异的成绩。
Teaching approach reform and innovation is a significant move to improve the teaching quality.The course of Electromagnetic Waves and Antennas covers a large number of complex formulae and is highly theoretical.To improve the effectiveness of the conventional classroom teaching and stimulate the students'learning motivation,this paper explores and practices a diversified teaching method that combines both virtual simulation and real-object demonstration.With focus on the key points and difficult points in teaching,we propose to build mathematical models for abstract concepts by using the software tools Matlab and HFSS to visualize the field properties of electronica waves,which is virtual simulation.In terms of real-object demonstration,we use small electromagnetic field demonstrating instruments and microwave test boxes to visually demonstrate abstract and complicated theories in class.Our teaching practices have proved that this kind of virtual-real combination between software and hardware can effectively promote the students'understanding and command of the systematic knowledge of electromagnetic wave from emission,propagation to reception,and improve the students'practice and innovation capabilities in electromagnetic engineering.The students also have achieved excellent results in the scientific and technological innovation competitions held at the school and national levels.
