Research On The Application Of Tracker Dynamic Capture Software In High School Mechanics Experiment Teaching

At present,the traditional high school mechanics experiment teaching has encountered the following difficulties: the collection of experimental data is too cumbersome to clearly and intuitively reflect the laws behind physical phenomena;too much emphasis on the explanation and teaching of knowledge theory,and ignore the practice and application of students;teaching methods are too rigid to improve students ’ interest in learning.Based on the traditional mechanics experiment teaching,this thesis introduces Tracker dynamic capture software as a teaching tool,and makes full use of the advantages of information technology to stimulate students ’ interest in learning,cultivate students ’ independent inquiry ability,and improve students ’ core literacy.In this thesis,the application of Tracker software in high school mechanics experiment teaching is studied by using the methods of literature research,practice research,interview and questionnaire survey.Three principles of Tracker application in high school mechanics experiment teaching are innovatively proposed: scientific principle,intuitive principle and exploratory principle.According to the above principles,three strategies of using Tracker in experimental teaching are summarized: Stimulating students ’ enthusiasm to participate in experimental exploration by taking problems as clues;Enriching experimental forms by using multimedia resources to highlight the interest of experiments;Giving full play to the advantages of computer technology to improve data collection and processing ability.On the basis of the above strategies,this thesis designs three teaching cases: exploring the law of car speed changing with time,the free-fall motion and the motion law of the simple pendulum.In these three teaching cases,Tracker is used to improve the shortcomings of the traditional experiment process,such as large error,unclear physical process,and difficult to intuitively display physical laws.Combined with the content of the textbook,the teaching process and the arrangement of teaching content are optimized to cultivate students ’ core literacy.In order to test the actual teaching effect of the software,the author selected two classes of one senior high school in a city,and carried out a two-month educational practice.The questionnaire and interviews with teachers and students were used to understand the learning situation of the students in the experimental class.The final teaching results were tested by comparing the test scores of the experimental group and the control group.The results show that the introduction of Tracker software to assist the mechanical experiment teaching can greatly improve students ’ interest in learning,promote students ’ active thinking,improve the efficiency of classroom teaching and make the physics classroom become lively.
