Innovative Exploration And Application Of Physics Demonstration Experiment In Junior High School

Physics is a subject based on observation and experiment.Classroom demonstration experiment is an important part of middle school physics experiment teaching.It is also the most popular experimental form for students.It not only establishes physical concepts and laws,but also understands and masteres physical knowledge Indispensable links,but also to develop students' ability to observe,thinking,exploring the spirit,and to master good learning methods.Some demonstration experiments,although the theoretical analysis is feasible but not ideal in the actual operation process.For example,there will be scientific not strong,poor contrast,the phenomenon is not obvious,the operation cumbersome,time-consuming and other conditions,some teachers in order to complete classroom teaching plan,just "prescription" rush to demonstrate again,only the experimental problems To find some reasons to prevaricate in the past,or simply change the experiment to do for the painting experiment,talk about the experiment.Due to the relaxation of the demonstration experiment requirements,naturally affect the classroom demonstration experiment teaching effect.In this paper,from the actual teaching of junior high school physics combined with the characteristics of the new physics curriculum in junior high school physics demonstration experiment and innovative principles to explore the experimental demonstration of the physics demonstration of junior high school related issues.Based on the characteristics of the junior middle school physics curriculum and the principles of the physics demonstration experiment,this article starts from the physics teaching in junior high school,and discusses the related problems of the junior middle school physics demonstration experiment innovation.This article adopts the method of literature research to understand the research status of classroom demonstration experiments,the status quo of junior middle school teaching in China and the status quo of experimental innovation of electric classroom demonstration,and to understand the theoretical basis of experimental innovation and provide a theoretical basis for the experimental innovation and practice in junior high school.Through the questionnaire survey,individual interview and classroom observation,this paper conducts a field study on the current situation of physics teaching in junior middle schools,pointing out the direction for the exploration of this article.Through the questionnaire survey in practice,we know the factors that may affect the implementation of innovative experiments.Through the investigation and analysis of the rationality of the teaching contents and the feasibility of the model,students can understand the advantages and disadvantages of the experiment and further analyze the feasibility of the experiment.Using comparative experiment method and action research method,two classes with similar levels were selected,which were experimental class and parallel class respectively.The two groups were taught Case 1,while the former used innovative experiment to implement teaching while the latter used traditional experiment to implement teaching.Through the practice of Case 1,the problems encountered in the case were analyzed and summarized and improved,and then Case 2 teaching.Finally,through the evaluation of the teaching content and teaching mode,students demonstrate whether the innovative experiment is applicable to the teaching of electricity and whether the students can adapt to the new experimental mode.
