电子信息专业《电磁场与电磁波》教学内容体系结构改革的探索

An Investigation of Teaching Content and Plot Structure's Innovation "Electromagnetic Fields and Waves" for Electronic Information Engineering

目前,《电磁场与电磁波》教材内容大致有两种体系结构:"静态场—麦克斯韦方程组—时变场"和"麦克斯韦方程组—时变场—静态场".对这两种体系结构各自的特点与不足进行了比较,在布鲁纳知识结构理论的指导下,探索了一种电子信息类专业的《电磁场与电磁波》教学内容新体系结构,即"真空中的电磁场与电磁波—介质中的电磁场与电磁波—电磁场与电磁波专题介绍",这一新体系结构克服原有教材体系结构的不足,使教材具有合理的静态结构与动态结构和与学生的接受水平相适应的呈现与传递方式.

Currently,Electromagnetic Fields and Waves teaching content has two different structures,which are ＂Static Field-Maxwell Equations-Time-varying Field＂ and ＂Maxwell Equations-Time-varying Field-Static Field＂.After comparing characteristics and limitations of the structures,and under the guidance of Bruner＇s theory,the paper tries to find a new kind of plot structure of Electromagnetic Fields and Waves for the major of electronic and information science.The new structure,which has overcome limitations of the original teaching material,is ＂Electromagnetic Field and Electromagnetic Ware in Vacuum-Electromagnetic Field and Electromagnetic Ware in Medium-Topic Introduction of Electromagnetic Field and Electromagnetic Ware＂.Besides,the structure makes static state structure and dynamic state structure of teaching material teaching material more logical,and has a suitable present and transfer mode for acceptable level of students.
