Design And Practice Research Of Junior Middle School Physics Demonstration Experiment Based On Living Materials

As a natural science based on experiments,physics demonstration experiment plays an important role in the middle school teaching process,which has attracted more and more attention from the department in charge of education and physics teachers.However,in actual teaching,physics demonstration experiments have not received due attention and good popularity,especially in remote and backward rural areas,physics demonstration experiments are rare.This paper based on the current situation of junior high school physics demonstration experiment resources and teaching implementation,proposes the use of living materials for junior high school physics demonstration experiment design and teaching practice research,to promote the resource construction of junior middle school physics demonstration experiments and the effective implementation of experimental teaching,promote the development of physics in junior high school students professional literacy,cultivate students' innovative spirit and practical ability.By referring to relevant literature,it is learned that the physical demonstration experiment based on life has always been valued by experts and scholars at home and abroad.Considering that when first contact with physics experiments middle school students mainly start with optical experiments,based on the analysis of the physics light phenomenon knowledge system in junior middle school,for the current situation of junior middle school physical light phenomenon demonstration experiment teaching,this paper designs a series of light phenomenon demonstration experiment based on living materials.These demonstration experiments have the characteristics of easy access to materials,simple principles and convenient operation.At the same time,the author applies the designed optical demonstration experiment based on living materials to practical teaching.Through practical discovery,the use of living materials for demonstration experimental teaching has effectively promoted the learning of physics subject for middle school students,transformed the learning method and improved learning ability,Stimulated interest in learning,cultivated students' innovative and practical ability,and also improved the level of teachers' education and professional knowledge.This thesis has five chapters:Chapter one The introduction part,mainly analyzes the current teaching status of physics demonstration experiment and puts forward questions,introduced the purpose,contents and methods of this thesis.Chapter two Describes the research history of physical experimental equipment at home and abroad,especially the design of simple physical experiments with living materials.Chapter three Analyzes the content of light phenomenon experiment teaching and the problems of experiment teaching implementation in the existing junior middle school physics textbook.Chapter four Froming the linear propagation of light,the reflection of light,the refraction of light and the dispersion of light,for different teaching content,author design different junior high school physical light phenomenon demonstration experiment cases based on living materials,and introduce the required materials,experimental operation steps,and analysis of experimental phenomena of these demonstration experiment.Chapter five By comparing with the traditional teaching process,the designed junior middle school physical light phenomenon demonstration experiment based on living materials is applied to specific teaching,and teaching feedback is carried out after implementation.Finally,summarized the research results of this article,that is,the characteristics of the demonstration experiment of physical light phenomenon based on living materials in junior middle school,and reflected on some problems encountered in the research process.
