Explore The Use Of Smartphone Sensors In High School Physics Experiments

With the development of science and technology,high school students now use smart phones.Junior high school students generally use mobile phones to surf the Internet,socialize and carry out some entertainment activities.In fact,as a highly integrated electronic product,the mobile phone is equipped with many sensors with different accuracy.The People’s Education Edition high school physics textbook repeatedly mentions sensors,and even involves many sensors for physics experiments,including sensors on smartphones for high school physics experiments.In view of the increasing importance of sensors in high school physics experiments,this article has carried out The use of sensors on smartphones for high school physics experiments is mainly to explore how sensors on smartphones are used in high school physics experiments,and to help high school physics teachers carry out mobile phone sensors to carry out physics experiments.This article firstly analyzes the high school physics textbook experiment knowledge framework and the "General High School Physics Curriculum Standards(2017 Edition)" issued by the Ministry of Education in January 2018.It analyzes the high school physics experiment and combs the high school physics experiment.Market research: The types of sensors on smart phones on the market and the sensors can measure the physical quantities involved in high school physics experiments.It is proposed that smartphone sensors be used in the design of high school physics experiments.Through the actual operation and analysis of the designed high school physics experiment through experimental methods,the following four experiments were successfully completed.The smartphone light sensor was used in the high school momentum conservation experiment,and the smartphone pressure sensor was used in the high school wave-ear law teaching experiment.The mobile phone acceleration sensor is used in the Newton’s second law experiment of high school,and the smartphone gyro sensor is used in the compound pendulum experiment.During theexperiment,the first-line high school physics teachers and physics experimenters were interviewed to improve the experiment.At the same time,the first-line high school physics teachers and experimenters were surveyed on the understanding,attitude and practical application of smartphone sensors in high school physics experiments.The success of the experiment and the attitude of the first-line teachers on this research indicate the feasibility of using smartphone sensors in high school physics experiments.At the same time,the market,literature survey analysis and experimental design in the study are for teachers and students who apply smartphone sensors to high school physics experiments.They provide a reference for the application of smartphone sensors in high school physics experiment teaching.
