Study On The Application Of Digital Experiment In High School Physical Mechanics Experiment Teaching

The General Senior High School Physics Curriculum Standard(2017 Edition)issued by the Ministry of Education in 2017 mentions "actively exploring the deep integration of information technology and physics teaching",which puts forward higher requirements for the organic combination of information technology and physics teaching.On the one hand,digital experiment can solve some difficult problems in traditional physics experiment,on the other hand,it can integrate information technology and physics experiment teaching effectively.In addition,many words related to digital experiments have appeared in physics textbooks and college entrance examination topics.It can be seen that digital experiments are being paid more and more attention by more and more people,and digital experiments should be taken into account.It is inevitable for the development of educational technology to use in physics teaching.However,through consulting the literature related to digital experiment and investigating its actual teaching situation,it is found that although there are more research articles related to digital experiment,the problems,doubts and difficulties encountered by teachers in reality are not combed.This has also caused a lot of teachers to the digital experiment resistance mentality.From this point of view,we can find out these problems and find the best way to apply digital experiment to physics teaching.This paper focuses on mechanical experiments,discusses the effects of digital experiments on students’ understanding of physical knowledge,arousing their interest in learning and cultivating students’ core accomplishment of physics,and explores the application of digital experiments.Methods and strategies in physics teaching.First of all,with the help of questionnaires to understand the use of digital experiments in senior middle schools in Shandong Province,the status quo of digital experiments is clear.Through the feedback of the questionnaire we find that the frequency of digital experiment is very low and most teachers are not particularly familiar with digital experiment but they are generally sure that digital experiment will bring benefits to teaching.Secondly,by summarizing and combing the problems existing in the traditional mechanical experiments and the corresponding aspects of the digital experiments,it is found that the digital experiments can be qualitatively and quantitatively and can not be done.The experimental effect of simplifying the complexity can also improve the students’ ability ofthinking and cooperation.Then,combining the application of digital experiment during school and practice,the author studies the learning obstacle of students in the process of using digital experiment,and finds that digital experiment can simplify the experiment process to a certain extent.This will reduce the chances of students’ hands-on practice and data processing as well as the use of mathematical knowledge to solve physical problems.In addition,students will be constrained by the problems of the materials such as the ideas designed by the teachers or the experimental manuals in hand when using digital experiments.This paper analyzes the problems of digital experiment in hardware and software,especially in mechanical experiment,such as the lack of some necessary sensors which are often used in mechanical experiment.The sensor is too sensitive and so on.The problems,puzzles and difficulties encountered by teachers in objective and subjective aspects in the process of using digital experiments are studied.Finally,aiming at the problems that often occur in mechanical experiments,such as time-consuming and laborious operation,which can only be "from theory to theory",two typical mechanical subjects,Newton’s second law and centripetal force,are selected to design the experiment and teaching process.Through the practice of teaching design,the principles that should be followed in the use of digital experiment are given: the principle of purpose,the principle of science,the principle of validity and the principle of students’ subjectivity.This paper provides four strategies for the use of digital experiments: quantitative analysis with the aid of digital experiments,transformation of traditional teaching methods,improvement of teachers’ experimental literacy and diversification of their use,with a view to providing work.To provide a certain reference for teachers in the front line.
