摘要
设计了电磁场与波课程的一项创新实验。其核心实验设计思想是用微功率白炽灯作为微波频段电磁波接收指示器,替代传统中价格昂贵的微波接收设备。从而,一方面可实现对电磁波"眼见为实"的感知;另一方面又能以有限的资金实现相应新实验设施的规模化建制。使每位学生可广泛、深入地参与和介入实验过程,进行课程设计和实验研究。该项新实验在电子科技大学的建设以及对已愈万名学生的实践教学应用中,起到了显著提升课程教学的效果。
An innovative experiment was presented to facilitate teaching and learning of the course of electromagnetic fields and waves.The basic and key methodologyal in the experiment design is to replace microwave apparatus for receiving electromagnetic wave with inexpensive micro-power incandescent lamps.The notable feature of the design is that the experiment can not only bring students the sense of seeing being truth when studying and realizing electromagnetic waves,but adequate numbers of apparatus can also be constructed with limited funds because of its low cost.Enough numbers of experiment apparatus would guarantee the chance for each student to do his interested experimental projects and related researches.This innovative experiment plays an active role in enhancing the effect of the course teaching and learning obviously.
