The Special Research Of High School Physics Demonstration Experiment Teaching Assisted By Smart Phone

Under the background of educational information reform,the physics subject takes the lead of science and technology to continuously implement and strengthen the deep integration between modern information technology and subject curriculum from all aspects,among which the use of information technology equipment to assist physical experiment teaching has become a hot research field,and the application and utilization of information technology has also been specially emphasized in the 2017 edition of general high school physics curriculum standard Mobile phones and other tools are convenient to solve some physics learning problems.This research takes smart phone,a powerful information technology tool with high popularity,as a special topic to help senior high school physics demonstration experiment teaching,and explores the effect and significance of smart phone to help senior high school physics demonstration experiment teaching from both theoretical and practical aspects.In the process of research,firstly,the author systematically expounds the research background,including the background of the times,the background of disciplines and the background of practice.Then,using the method of literature review,the research significance,research status and theoretical basis at home and abroad are investigated in detail;and based on the above basis,the feasibility of the research scheme is analyzed and demonstrated.Next,according to the three directions of effective observation of the phenomenon of smart phone assisted physics experiment,convenient measurement of assisted physics experiment data and real-time demonstration of assisted Physics Virtual simulation experiment,the collected and developed smart phone assisted physics experiment materials for senior high school are summarized and discussed in the way of special research.Finally,the quasi experimental research method is used to carry out the research of the practice link.Before the practice,the preliminary investigation is carried out on the experimental objects and environment by means of questionnaires,interviews,teaching and research activities,etc.the investigation contents include the basic situation of senior one students' using the hand machine in life,learning and physical learning;teachers' suggestions and opinions on helping senior high school physical demonstration experiment teaching.According to the research results,modify the content of the experimental scheme,further explore the experimental functions of smart phones,break through the difficulties of traditional demonstration experiments,and further ensure the scientific design of the experimental scheme.In the end,three experiments in the compulsory one of senior high school physics were selected: Newton tube demonstration experiment,measuring the acceleration of gravity through free fall motion,studying the demonstration experiment of overweight and weightlessness,the experimental group carried out the mobile phone experiment,and the control group carried out the traditional experiment;then,using the pre-designed and selected effect detection project tools,the students' physical performance,learning motivation before and after the experiment were tested Through the comparative analysis of curiosity and interest,we can get the practical effect of the smart phone to help the high school physics demonstration experiment teaching.Finally,the conclusion of the special research shows that there are a lot of resources to use smart phone to assist teaching in high school physics demonstration experiment,and the experimental scheme has strong feasibility.It is found that the mobile phone experiment mainly covers the following advantages: first,it is helpful to observe the experimental phenomena,such as slow motion shooting,slow down the experimental process,and instant experimental phenomena can be observed at any time by freeze frame picture;second,the built-in sensor of the mobile phone can accurately and conveniently measure the experimental data,and students can draw the experimental conclusion by analyzing the experimental images displayed,which can be forged To improve students' ability of image processing and analysis.Thirdly,many mobile apps also provide teachers and students with rich virtual simulation experiment resources and create conditions for their mobile learning.Fourthly,the practice results show that the implementation of mobile phone assisted physical experiment can improve students' motivation,curiosity and interest in physics learning to a certain extent.In a word,smart phones can help the special research of physics demonstration experiment teaching in senior high school,help to break through the difficult problems of physics demonstration experiment,improve and optimize the experiment scheme,and strengthen the effect of physics experiment classroom teaching.
