摘　　要：将信息技术融入到电磁学实验的教学理论和实践中,能优化教学结构,有效提高教学效率,同时培养学生物理建模的意识和能力.以静电场、稳恒磁场的相关物理量的测量实验为例,通过GeoGebra软件,动态模拟实验目标的呈现,绘制等势线分布图和磁感应强度分布曲线,进行数据分析和误差分析.结论表明,在GeoGebra软件辅助下,教师能更直观地讲述实验原理,学生能更准确快捷地处理实验数据和判定实验结果的准确性.Integrating information technology into the teaching theory and practice of electromagnetism experiment can optimize the teaching structure,improve the teaching efficiency effectively,and cultivate the students’consciousness and ability of physical modeling as well.Based on the measurement experiment of the relative physical quantity of electrostatic field and steady magnetic field,the GeoGebra software is used to dynamically simulate the presentation of the experimental target,draw the isopotential line distribution map and the magnetic induction intensity distribution curve,and carry out data analysis and error analysis.Conclusion:with the help of GeoGebra software,teachers can tell the principle of experiment more intuitively,and students can process the experimental data more accurately and quickly and judge the accuracy of experimental results.
