Analysis Of Experimental Design Of Physics Innovation In Junior Middle School

Innovation is an inexhaustible driving force for development,ranging from a game to a country.If you do not want to be eliminated by the times,you must innovate.Physics is a natural science based on experiments.Experiments are the most vivid and lively teaching forms in physics teaching,and innovation experiments have a prominent role in cultivating students 'innovative literacy.Analyzing the general approach of physics innovation experiment design in junior high school is helpful to improve the professional level of physics teachers,and thus improve the teaching status of innovation experiment.In this paper,using the method of literature analysis and research,classroom observation,based on the national contest of young teachers in high school physics teaching award of video observation,combined with examples in the video from the experiment equipment,experiment method,experiment contents,experiment form four aspects of junior middle school physics experiment analysis,the design way of innovation of experimental design:In terms of experimental equipment,it is necessary to seize the common parts of living materials and laboratory equipment to replace them,select new materials based on the characteristics of the subject,and reorganize the experimental equipment for the purpose of the experiment.In terms of experimental methods,we need to diversify,select contrast method and simulation method to promote students 'understanding,and select magnification method and conversion method to assist observation.In terms of experimental content,students 'awareness of the problem is cultivated by creating real problem situations,their perceptual understanding of abstract concepts is obtained by adding textbook experiments,and students' ability to comprehensively use and process information is promoted through interdisciplinary design.In the experimental form,the small magic small games arouse the suspicion,leave the space for students to innovate through selective experimental forms,and provide students with the opportunity to discover problems and innovate by changing the demonstration experiment.Based on the above analysis,I was inspired by the above analysis: before the design,we should carry out the preliminary analysis of teaching materials,learning situations and teaching objectives,and inspire the inspiration of innovative experimental design;The design should start from the experimental apparatus,experimental method,experimental content and experimental form.The existing innovative experimental design should be continuouslyimproved;Scientific and reasonable,simple and reliable and novel and interesting should be achieved in the process of innovation experiment design.
