The Research On Teaching Design Of High School Physics “mechanical Energy” In Digital Experimental Environment

The Ministry of Education issued a new standard of high school physics curriculum in 2017.The new curriculum standard mentioned that we must attach importance to digital experiments and innovate the methods of physical experiments.Modernized teaching methods have expanded the way to learn physics,help students understand physics knowledge,and enable students to experience the close connection between modern technology and physics.Nowadays,information technology is gradually changing the educational concept and teaching methods.Among them,the digital experiment and their application in experimental teaching are typical representatives of the application of modern information technology in physics teaching.It also appears in the high school physics textbooks and college entrance examination questions.It can be seen that the high school physics teaching in the digital experimental environment is the general trend of the development of educational technology.This paper analyzes the development background and significance of digital experiments,and designs and implements the teaching of applied digital experiments for the "mechanical energy" part of high school physics,forming optimized plans for teaching design,thereby explores and analyzes consequently the value of digital experiments.This research mainly includes six parts.The preface of the first part introduces the research significance of the topic,and then expounds the research methods and theoretical basis of the paper.The second part is literature summary,through the search,analysis and comparison of the literature and data,to understand the development and application of digital experiments at home and abroad.Among them,in terms of domestic research and application,it mainly analyzes the application of digital experiments in textbooks,literature,and the high exam papers.It also analyzes the research status of digital approach in high school physics experiments.The third part is an overview of the digital information system.It introduces the structure principle of the digital information system and its advantages and disadvantages in the middle school physics teaching.The fourth part of this study is aimed at the content of the "mechanical energy" part of high school physics,designed three experiments based on digital methods,and completed the corresponding teaching design.Based on the previous experimental designs and instructional designs,the teaching was implemented in the physics classroom of high school.The content of the fifth part is based on classroom observations and feedback and evaluations from students,peers and themselves.It proposes problems in teaching and optimizes the corresponding teaching links.The sixth part is the summary,reflection and prospect of this research.Through the research of this paper,it is found that the application of digital experiment in senior high school physics experiment teaching has many advantages,although it cannot completely replace the traditional high school physics experiments,it is the general trend to apply it to teaching more widely in the current digital age.Therefore,through the teaching design research of high school physics under the digital experiment environment,the teaching design of applying digital experiment is formed to provide more in-service teachers with the lesson preparation process,in order to provide valuable teaching design reference for high school physics teaching.
