Excel 软件是 Microsoft office2000办公软件之一,它具有数据统计、分析功能,能进行复杂的公式运算,能把数据快速准确地以图像的形式描述出来,并且易学易用。如何挖掘它所具有的优势为物理教学服务,本文拟从 Ex-cel 在物理教学中应用以促进信息技术与中学物理教学的整合和学生探究学习,谈谈自己的一些做法。一、简化复杂的数值运算在物理教学中经常遇到复杂的数值运算,比如有一道物理习题要求计算周期为5小时的卫星距地面的高度,我们可以根据已学知识很快地推导出周期与高度关系的表达式 T=2π(r~3/gR~2)~(1/2),其中 R 是地球半径,r 是卫星
Excel software is one of the Microsoft office2000 office software. It has data statistics and analysis functions, can perform complex formula calculations, can describe data quickly and accurately in the form of images, and easy to learn and use. How to tap it has the advantage of physics teaching services. This article intends to use Ex-cel in physics teaching to promote the integration of information technology and middle school physics teaching and student inquiry learning, and talk about some of their own practices. First, to simplify the complex numerical calculations in the physics teaching often encounter complex numerical operations, such as a physical exercise requires the calculation period of 5 hours of the satellite from the ground height, we can quickly derive the cycle and The expression of the height relationship T=2π(r~3/gR~2)~(1/2), where R is the radius of the Earth and r is the satellite
