Research On Experimental Development Of Physics Innovation In Middle School

Physics is based on experimental science,and experiment is an important basis,content,method and means of physics teaching.The development of innovative experiment in the physics teaching of middle school can not only make up the deficiency of existing experimental teaching,improve the teaching effect,but also cultivate students' innovative consciousness and innovation ability.In the teaching of physics in middle school,I have developed 22 innovative experiments and applied them to practical classroom teaching,which has improved students' learning interest and learning effect.The development of innovative experiment needs to be supported by innovative thinking.From the perspective of psychology,the paper studies the general process of experimental creative thinking: problems,path solving,Epiphany,inspection method and innovation.The corresponding design process is put forward: preliminary analysis,experimental design,experimental production,experimental application and experimental evaluation.This paper from improving the experimental teaching materials,the introduction of new experiment,the principle of innovation,equipmentinnovation experiment Angle,shows the use of grafting,contrast method,substitution method,conversion method,such as the development of eight experiments of design thinking: capacitor charging and discharging the demonstration,the electromagnetic damping experiment teaching demonstration,the frame of reference,center of gravity of inquiry experiment,elastic potential energy expression inquiry experiment,buoyancy causes to explore,magnetic induction intensity probe,the photoelectric effect demonstration experiment,points out its compared with the advantages of the traditional processing way.In this paper,two specific cases of inquiry teaching are introduced based on innovation experiment: the experimental investigation of the conservation of mechanical energy and the experimental investigation of electricity phenomenon.The design principle and idea of experiment are introduced in detail,and the general process of application in specific classroom teaching is presented.
