High School Physical Mechanics Digital Expansion Experimental Research

Physics is an experiment-based science.There are a lot of physics experiments in middle school physics teaching,including teachers'demonstration experiments,students grouping and so on.According to different classification methods,there can be a lot of different types of experiments.Experiments play a pivotal role in physics learning,With the development of science and technology,Experimental equipment used in physical experiments has also made continuous progress,Many modern experimental platforms came into being,Digital information experimental system is entering the middle school classroom,High accuracy of digital experiment and convenient data processing,And these modern experimental equipment make the middle school physics experiments have more space for innovation and expansion,Whether for the teacher,Or for the students,Both provide more convenience and more creative possibilities,This is also in line with the curriculum standard requirements to improve students' scientific inquiry ability and improve students'core literacy in physics.So how to make good use of these digital experimental equipment?How can the students improve in the experiment?This paper mainly studies how to use the digital experiment system——to use the PASCO experiment system to expand high school physics,cite some experimental cases for reference,and put forward some corresponding suggestions.First of all,I consulted the data,reviewed the development of digital experiment platform at home and abroad,analyzed the widely used digital experiment system at home and abroad,and then summarized the application of digital experiment platform in middle school physics experiment and the physics expansion experiment in middle school for Chinese scholars.Then we introduce relevant educational theories,such as "constructivist learning theory",Dewey' s "learning" theory and "learn with technology" theory,digital experiment,expansion experiment,digital development experiment,and define the digital experimental system,the composition of the PASCO experimental system and the advantages of the digital experimental system.Then with their own internship experience and learning experience to briefly talk about the digital expansion of experimental courses in middle school;Then there are three digital expansion experiments that can be conducted in the expansion experiment classroom,Inspired by my tutor during the postgraduate study stage,I began to design an experimental case of——,"measuring the mass of objects in Earth simulated space",The tutor also gave the experimental ideas:"overweight,weightlessness",With the help and inspiration of the teachers,Thinking that these experiments can be used in the extended experimental course of high school physics and mechanics,Expand the scope of student experiments,Improve the students'ability of experimental exploration,In addition,two other cases that can be used in middle school experiments are "research on the phenomenon of ball motion","Use mobile phone physics workshop to explore the phenomenon of overweight weightin the elevator",These three experimental cases include the applicable inquiry topic,the detailed design ideas,the experimental steps,the link preset of the teaching implementation,and the summary and evaluation,Provide an idea for other teachers to expand their digital experiments.Finally,mainly illustrates the digital development experiment in the real implementation of what difficulties,and to achieve the desired effect,schools,teachers and students need what efforts,and my reflection in the experimental research,and then for conditional physical digital development experiment teachers provide some advice,and in the middle school in our country physical digital development experiment some expectations and prospects.
