Design And Development Of High School Physics Experiment Based On Smart Phone

Under the background of information age,it is inevitable for information technology to penetrate into various disciplines.In the field of discipline education,we are actively exploring the mode and way of deep integration of information technology and curriculum.As far as physics is concerned,digital experiment system has unique teaching advantages,so digital experiment has always been the focus of physics educators《The physics curriculum standard for senior high school(2017 Edition)》clearly points out that "digital experiment system is not only the need of the development of education informatization,but also an important method and means to cultivate students’ innovation ability".However,due to the high cost of professional sensor equipment,digital experiment has always been difficult to be widely promoted.In recent years,the combination of smart phones and physics experiments has attracted the attention of physics educators all over the world,and has gradually become a research hotspot.As a new carrier of digital experiment,smart phone has the advantages of high popularity,accurate measurement and convenient carrying.Therefore,in order to promote the deep integration of information technology and physics experiment teaching,and explore a variety of ways of physics experiment teaching and students’ learning,we should give full play to the value of smart phones in physics experiment teaching,and make them a favorable tool for students to learn physics knowledge.Firstly,this paper reviews the research status at home and abroad,summarizes the application of smart phones in physics experiment teaching at home and abroad,especially analyzes some typical cases in mechanics,vibration and wave,optics,magnetism,electricity and other fields,and determines the shortcomings of the existing research,That is,the lack of electrical experiments and the lack of extracurricular experiments.Based on constructivism theory and audio-visual education theory,this paper selects the methods of literature analysis and experimental research,combines with the technology of Bluetooth extension of phypox,takes Arduino ide as the software environment,and carries out the experimental design and development research with the cooperation of smart phone,esp32 and ads1115 single chip microcomputer.In the process of specific research work,focusing on the design of high school physics electrical experiment,and taking "capacitor charging and discharging" as an example,the implementation method of electrical experiment based on smart phone and related technology is introduced in detail;Taking the design of high school physics extracurricular experiment as another key point,based on the different functions of smart phones,this paper designs and develops some high school physics extracurricular experiments,and introduces four types of extracurricular experiments in detail:production type,exploration type,measurement type and verification type combined with specific cases.After that,the designed experimental scheme is verified and evaluated.Through the above research,it is found that the development of high school physics electricity and extracurricular experiments can be well realized based on smart phones,and it has the advantages of low cost,high precision,easy access,high integration and so on.Therefore,the application of smart phones in high school physics teaching can effectively make up for the shortcomings of traditional experiments,greatly improve the quality and efficiency of physics teaching.At the same time,students can experience the fun of using smart phones to carry out experiments and explore,freely explore,discover and verify the laws of the natural world,so as to improve students’ scientific literacy.In addition,it can also change the bad habit of students addicted to mobile phones,and guide students to correctly use modern tools to assist learning.
