Research On The Improvement And Innovation Of Mechanics Experiment In The Junior Middle School

Science and technology are the primary productive forces,and innovation is needed to promote the progress of science and technology in the new era,especially experiment as an important part of physics teaching.Physics experiment is not only to complete it.At the present stage,there are some problems in junior high school physics experiment,such as weak intuition and inconvenient operation.There is also the phenomenon of "talking experiment" in physics teaching in junior high school because there is no equipment.Based on previous literature of peace,he saw and heard in the study life at the study of junior middle school mechanics experiments and analysis,and a questionnaire to all students,in the middle school teacher interview and survey at this stage of junior middle school mechanics experiment teaching present situation,summarizes the mechanics experiment teaching problems and reasons,put forward combining with the existing literature improvement and innovation should follow the principles of mechanics experiment,and under the guidance of these principles are found in some junior middle school physics mechanics experiments,and some experiments of junior high school physical and mechanical parts is improved,to achieve better teaching effect,in order to rich the junior middle school mechanics experiment teaching resources.The research methods used in this paper include literature research,comparative analysis,questionnaire survey and interview.This paper is divided into five chapters: the first chapter is the source of the problem,the research purpose and the significance;The second chapter is the junior high school physics experiment improvement and innovation related concepts and theoretical basis;The third chapter through the questionnaire survey and analysis of junior high school physical mechanics experiment problems;The fourth chapter is the case analysis of the improvement scheme of mechanical experiment.Chapter five summarizes the thesis.According to the research,there are few relevant literature on junior high school mechanics experiment.Based on the questionnaire survey and interview,this paper summarizes the principles of improvement and innovation of junior high school mechanics experiment and proposes the improvement approach.First,change the structure of the instrument to improve the visibility of the experiment;Second,the experiment can be made more environmentally friendly by selecting suitable and feasible alternatives when the experimental results are consistent.Thirdly,make use of the waste materials around and make experiment equipment.Fourth,change the material of the equipment to make the experimental effect better;Fifth,replace the experimental equipment and add the experimental function on the basis of the original experimental scheme;Sixth,add digital instruments to improve the accuracy of the experiment and keep pace with the times.
