The Improvement And Innovation Of Physics Experimental Teaching Instruments Of Middle School

The Physical experiment teaching is the basic content of Physics teaching in middle school,is an important way to cultivate students' scientific spirit,is an effective method for the implementation of high school Physics teaching,is a necessary means to improve core competence of physics.At the same time,experimental operation ability and scientific inquiry ability is also an important goal of Physics teaching in middle school.Therefore,physics experiment teaching plays an important role in Physics teaching in middle school.However,at present many ordinary schools,especially in rural schools or underdeveloped areas of middle school physics experiment teaching still exist many problems-experimental teaching instruments or equipment and other teaching aids resources are lack of quantity,low quality,slow update speed,high damage rate,lack of visual and interesting interest in demonstration.So,It is of important practical significance to improve or innovate the teaching aid of physics experiment in middle school.First of all,the thesis embarks from the research background,research status,discussed the current domestic about this problem in the research and teaching of the problem,determine the research content,proposed research methods of the subject,explicit the research significance.Secondly,according to the theory,puts forward the basic principles of improvement and innovation of teaching high school physics experiment: Science,safety,visual and interest,inquiry and so on;explores the basic ways of improvement and innovation of teaching of high school physics experiment.Then,combining "atmospheric pressure" section of middle school physics carry out the improvement and innovation of the experimental teaching instruments case study,mainly introduces nine typical cases improved or innovation,such as the "Magdeburg hemispheres experiment"," Torricelli experiment" and "Drinking cup",and will be improved the application of experiment teaching in junior high school physics teaching practice,after a survey of the teaching effect and peer assessment,analysis and conclusion.Finally,a brief summary of this topic is made: the stage results of this study are expounded,the existing problems and shortcomings are analyzed,and future researchplans and plans are formulated.Improvement and innovation of physical experiment teaching in middle school is a research topic of the world without end,is a vast expanse of the experimental field,is also an inexhaustible teaching resources,in this regard,we should be confident,and never stop,with incomparable enthusiasm and courage to practice exploration.
