A Study On The Application Of Digital Technology In Physical Experiment Teaching In Middle School

Digital technology is a process of presenting the expected experimental results with the help of computer software,which can be used to convert sound signals,optical signals and thermal signals into electrical signals.Practical ability,cooperation ability,image processing ability and data processing ability can be improved by means of the application of digital technology in middle school physics experiment teaching.The requirements of the new physics curriculum standard of middle school have changed from three-dimensional objectives(knowledge and skills,processes and methods,emotional attitudes and values)to advanced core competence(physical idea,scientific thinking,experimental exploration,scientific attitude and responsibility).Based on the digital technology,the author focuses on the design and development of the digital experiment of crystal melting,the digital experiment of the relationship between acceleration and force,mass,and the digital experiment of horizontal throwing movement.Through these three experiments,the advantages of digital technology in physics experiment teaching in middle school are explained.These are the advantages that traditional physics experiment teaching does not have.The background,current situation,methods and significance of the research are introduced in detail in the first chapter.The theoretical basis of the research including constructivism learning theory,meaningful learning theory and Dewey's learning theory of "learning by doing";is stated in the second chapter.The statistical analysis of questionnaire survey has been presented in the third chapter.The subjects of questionnaire survey contain 50 middle school physics teachers and 200 middle school students.In fourth chapter,it mainly includes three aspects:(Digital Experiment of crystal melting),(Digital Experiment of relationship between acceleration and force,mass),(Digital Experiment of flat throwing motion).In fifth chapter,it has compiled the teaching design case of digital experiment of crystal melting experiment for junior high school and the relationship between acceleration and force,mass and flat throwing motion for senior high school.The conclusion and prospect of this study,as well as the summary and reflection of this paper are presented in the sixth chapter.
