物理学是一门以实验为基础的科学。随着信息技术的发展,DIS(DigitalInformation System,数字化信息系统)在高中物理实验中的普及是未来的趋势。一方面,将DIS与传统的实验设备有机整合,可以方便地进行过去无法做的探究实验,例如对磁场的定量研究等;另一方面,计算机自动采集数据并作图,实现了对大量实验数据快速、准确的处理,有效提高了课堂效率。笔者利用DIS设计并开展了一系列关于电磁学的学生探究活动,让“隐形”的电
Physics is an experiment-based science. With the development of information technology, the popularization of DIS (Digital Information System) in high school physics experiment is the future trend. On the one hand, the organic combination of DIS and traditional experimental equipment can be easily carried out in the past can not do the exploratory experiments, such as the quantitative study of the magnetic field; the other hand, the computer automatically collect data and mapping, to achieve a large number of experimental data Fast and accurate processing, effectively improve the classroom efficiency. The author uses DIS to design and carry out a series of student inquiry activities on electromagnetism, so that “invisible ” electricity
