High School Physics Based On Arduino And Lab VIEW Development And Teaching Practice Of Digital Experiment

Firstly,the current situation and existing problems of domestic and foreign digital experiments and self-developed digital experiments were analyzed in this paper.Secondly,the teachers,students and laboratory administrators of the school in the practice area were investigated and interviewed.the feasibility and precautions of this self-developed digital experiment were determined.Then,adhering to the principles of scientificalness,educative nature,artistry,inspiration and subjectivity,taking Arduino development board as the core and Lab VIEW as the data processing platform,It has developed six digital experimental resources related to physics experiment teaching in senior high school,such as "measurement of instantaneous velocity","exploration of motion law of free falling body","exploration of the relationship between acceleration,force and mass","exploration of factors affecting the period of single pendulum","verification of mechanical energy conservation" and "trichromatic light expansibility experiment".Then,based on the constructivism theory and hybrid teaching theory,in order to promote the core quality of students’ physics as the main line,the corresponding teaching design is carried out for the four experiments of "measuring instantaneous velocity","exploring the law of free fall movement","exploring the relationship between acceleration and force and mass" and "exploring the factors affecting the period of single pendulum".Finally,in teaching practice,the teaching effect of self-developed digital experiment in practical teaching application is analyzed by setting up experimental class and control class.Through development and research,it was found that the digital experiment developed by Arduino and Lab VIEW can almost be equivalent to Langwei digital experiment in terms of performance,function and effect etc.However,it has the unique advantages of low price,portability and good replicability,which provides a new means for the popularization of digital experiment.Through the actual teaching practice,it was found that the independently developed digital experiments can stimulate students’ learning interest much more,and promote students’ understanding of physics knowledge to a certain extent.Through the analysis of the results before and after the experimental class and the control class,it was found that the application of self-developed digital experiment in teaching has a certain positive impact on students’ academic performance,especially the problems related to digital experiment.
