Development And Application Of Low-cost Experiments In Junior High School Physics

Physics is an experimental-based natural science.There are many experiments in the middle school physics curriculum.These experiments can use the low-cost materials in life to make experimental equipment and use it in the classroom.This paper is devoted to combining low-cost experiments with theoretical teaching and applying them to teaching.In the teaching process,low-cost experiments can firmly attract students' attention,focus their attention on the experiment,improve their participation in the experiment,and cultivate their interest.Therefore,the teacher should combine the teaching content,make use of various bottles and cans in life to make experimental equipment,and introduce the equipment to the students,so that they have a good impression on the upcoming experiment and actively think about it.Firstly,through the consultation of relevant literature and materials,the background of the topic was introduced,the research status at home and abroad was expounded,the significance of the research was emphasized,and the research content and method were clarified.Secondly,questionnaire survey,teacher-student interview,instrument statistics,etc.Conducted a practical survey in the internship school,solved the situation and reasons for the low-cost experimental teaching of the school,and proposed how to apply low-cost experiments to the teaching solutions and methods,laying the foundation for future practical teaching;Using the internship school as a platform,the low-cost experiment was applied to the classroom and the contrast teaching was carried out.The low-cost experiment was applied to the teaching,and the comparative teaching mode of �Experiment A Class� and �Experiment B Class� was set up.Continuous exploration and improvement in the process,ingeniously integrating low-cost experimental teaching into the physics teaching process,and analyzing the teaching effects of the two classes,found that the use of low-cost experimental teaching enables students to master physics from the understanding of physical phenomena.Knowledge,using actual teaching achievements to prove the implementation of low-cost experimental teaching.
