GeoGebra在模拟电路图解法教学中的应用

The Application of GeoGebra in Teaching Analog Circuit Graphic Method

GeoGebra是一款具有强大动态绘图功能的辅助教学软件,可将抽象的电路问题可视化展示,并增强电路教学的互动性。针对模拟电路图解法教学课件静态图片无法生动展示图形的动态变化、输入回路与输出回路的图形无法联动、无法试验验证消除失真的方法的问题,借助GeoGebra软件的动态特性开发了GeoGebra图解法动态课件。将该课件运用于课堂教学可动态展示模拟电路图解法中图形的变化,并可引入探究式的教学方式。GeoGebra动态课件的应用能有效提升学生的学习效果,可在电子电路课程教学中推广使用。

GeoGebra is an assistant teaching software with powerful dynamic drawing function,which can visualize abstract circuit problems and enhance the interactivity of circuit teaching.In order to solve the problems that the static pictures of analog circuit graphic method teaching courseware can not vividly show the dynamic changes of graphics,the graphics of input and output circuits can not be linked,and the method of eliminating distortion can not be verified by experiment,a GeoGebra graphic method dynamic courseware is developed with the help of the dynamic characteristics of GeoGebra software.Applying this courseware in classroom teaching can dynamically show the changes of graphics in analog circuit graphic method and introduce an exploratory teaching method.The application of GeoGebra dynamic courseware can effectively improve students’learning effect,and can be widely used in electronic circuit teaching.
