基于手机的随机误差统计规律实验数据处理方法

DATE PROCESSING METHOD OF DISTRIBUTION LAW OF THE RANDOM ERROR EXPERIMENT BASED ON SMART PHONE

大学物理教学中包含的随机误差统计规律实验项目要涉及大量的数据处理,本文介绍了如何基于智能手机的节拍器、秒表以及WPS软件,加快时间测量中随机误差的统计规律实验进程。针对经典的数据处理软件Origin和Excel大多只能够在PC端运行的限制,结合自身的教学实践,利用智能手机中WPS软件,对手动采集的大量时间测量实验数据进行自动处理,快速得到实验结果。学生无需到实验室进行实验,实验效果明显,实验效率显著提升,激发了学生学习兴趣。在移动学习模式广泛应用于教学,且智能手机普及的今天,具有较强的推广价值。

There are a lot of data involved in the experimental project of random error statistical law in college physics teaching.Traditional data processing requires a lot of calculation.This paper introduces how to speed up the experimental process of statistical law of random error in time measurement based on metronome,stop watch and WPS software in the smart phone.Break through the limitation that most of the classic data processing software like Origin and Excel can only run on PC,combined with our teaching practice,WPS software in smart phone is used to automatically process a large number of time measurement experimental data collected manually and get the experimental results quickly.By this approach,students do not need to experiment in the laboratory.Not only the accurate calculation results can be output extremely fast,but also experimental efficiency is significantly improved.Besides,students'interest in learning is stimulated.In recent time,when mobile learning mode is widely used in teaching and smart phones are very popular,this method has strong promotional value.
