Practical Research On Improvement Of High School Physical Mechanics Demonstration Experiment

Experiment is the foundation of physics research and the basis of physics teaching.Physical demonstration experiment teaching is an important part of physics teaching.It is also a popular experimental form in physics classroom teaching.By setting up some physical demonstration experiments,there are conducive to the introduction of new lessons,the emphasis of teaching and the consolidation of knowledge,etc.Good classroom atmosphere can be created to inspire students to learn physics and achieve better teaching results.With the introduction of core literacy,the teaching of physical demonstration experiments is also conducive to cultivating students' scientific thinking and scientific attitudes,as well as improving students' scientific inquiry ability and ability to solve practical problems.In order to better play the role of physical demonstration experiment teaching,it is imperative to study the improvement of physical demonstration experiments.This topic focuses on the improvement of the physical demonstration experiment in the mechanics of the compulsory part.The research mainly uses analysis of the teaching materials for the problems arising from the high school mechanics demonstration experiment teaching.After many studies and practices,the mechanics demonstration experiment is improved and the corresponding improvement strategies are put forward to form own ideas for the improvement of high school physical mechanics experiments in order to fully play the positive role of demonstration experiments.It can help students form scientific thinking habits,develop students' scientific inquiry ability and core literacy.The paper is divided into four parts:The first part:Explain the background of the problem and then clarify the research purpose,significance,content and methods through the analysis and understanding of the research status,and summarize the relevant theoretical basis.The second part: The problem existing in the current physical demonstration experiments were summarized on the basis of questionnaires and analysis of high school physics compulsory textbooks.The third part: Aiming at the problem and improving the existing theoretical research according to the experiment by consulting the data and combined with own practical experience.Put forward improvement plan for the compulsory part of the mechanics demonstration experiment and the corresponding improvement strategy.The fourth part: The experimental design of the teaching fragment is carried out on the improved demonstration experiment schemes such as “factors affecting the magnitude of gravity potential energy” and “overweight and weightlessness” combined with the proposed strategy.
