Our resarch consists of two parts. The first is construction of knowledge data-base for student to study electromagnetics. This knowledge data-base are hierachically structured and used the overlay-student model.The second is visualization of the imaginary electric field for student to understand and recognize the concepts of electromagnetics, such as "electric-potential" and "intensity of electric field". The field is composed for student to be able to understand and recognize thier concepts. Each eoectric potential is colorfully displayd and each intensity is showed by the length of arrow by its values. By this resarch, student can do well concept leraning.

我们的研究由两部分组成。一是建立学生学习电磁学的知识库。该知识库采用层次化结构，采用叠加学生模型。二是虚拟电场的可视化，便于学生理解和认识电磁场的概念，如电势、电场强度等。这个领域是为了让学生能够理解和识别他们的概念而编写的。每个电势是彩色显示的，每个强度用箭头的长度和它的值表示。通过本研究，学生能够较好地进行概念学习。
