The Research On The Middle School Physics Experiment Teaching Based On Smartphone

With the continuous advancement of technology,mobile phones have been upgraded from the initial only basic on communication functions to smart carriers that integrate multiple kinetic energy.The most obvious feature of smart phones is the integration of multiple sensors,such as light sensors,distance sensors,gravity sensors,acceleration sensors,and magnetic sensors.The APP software interface developed on this basis makes it possible to carry out physical experiment research.As a tool for assisting physical experiments,the smartphone sensor APP has the advantages of high penetration rate,accurate measurement,and flexible portability compared to digital information system(DIS)sensors.This thesis studies the strategy of introducing smart phones into the teaching process of physics experiments in middle schools,and using the built-in sensors of smart phones with the help of “Phyphox” software for teaching design of physics experiments.Considering that most schools do not allow students to bring mobile phones into the campus,but students can use their smartphones to reproduce the teacher's classroom experiment process after class to deepen their understanding and mastery of the experiment;To inspire enthusiasm for learning and cultivate innovative ability.This article is divided into seven parts:The first part: collect and sort out the relevant literature materials,clarify the feasibility of the topic selection,and summarize and summarize the research status.Part ?: Based on the theory of constructivism,learning motivation theory and Dell's Tower of Experience,it narrates the relevant pedagogical concepts that support the physics experiment of smartphones expounds the feasibility of using smartphones to carry out physics experiments;Components and related functions.Part ?: Based on the theoretical research in the first two chapters,combined with the characteristics of physics experiment teaching,it summarizes several basic principles that should be followed when designing physics experiments on smartphones: applicability,innovation,repeatability,and intuitive design,And the principle of teaching practice that takes students as the main body,cultivates scientific practical ability,and connects with the reality of life.Part ?: Designing experimental cases,using smartphone acceleration sensors,pressure sensors,and sound sensors in combination with Phyphox software to design experimental cases,specifically introducing experimental background,experimental principles,experimental devices,experimental processes,experimental results,and experimental reflections.Part ?: Gives two specific instructional design examples,demonstrates how to integrate the experimental cases of smartphone design into the specific instructional design,and puts forward the issues to be noted in instructional design.Part ?: Discuss the significance and role of extracurricular physics experiments,and give examples of six extracurricular physics experiment exploration activities based on smart phones.Use the sound sensor to measure the sound intensity in the environment,measure the speed of sound,explore the relationship between the pitch of the guitar string and the frequency,explore the change in the pinball height and the energy change in the process;use the barometric pressure gauge to measure the floor height and altitude,and explore the gas The relationship between pressure and flow rate.Part ?: Conclusions and reflections.The smartphone application has enriched in-and out-of-class experimental exploration activities in physics experiments.At the same time,reflect on the shortcomings in the research process.
