The Design And Application Of Microcourse To Improve The Modeling Ability Of High School Students In Physics And Mechanics

With the introduction of the core quality of physics,educators are paying more and more attention to the cultivation of students' ability to construct physical models.However,in our physics teaching,the model teaching starts late,the senior high school student constructs the physics model ability to be weak,uses the physics model to solve the question ability to be urgent to enhance.In the teaching practice,we found that senior high school students have a shallow understanding of physical model,and their consciousness of solving practical problems with physical model has not been formed.Therefore,this research thinks that we should provide an effective "handle" for senior high school students to construct physical model,which is convenient for students to apply the physical model at any time,and increase the application frequency of the model,improve students' consciousness of applying physical model,and then improve their ability of constructing physical model.With the continuous development of science and technology,great changes have taken place in the educational means.The newly emerging information-based educational means are welcomed by the majority of educators and educatees,it brings great convenience to education and teaching.Micro-class time is short,the content is fine,the use of fragmentation time can be repeated at any time,anywhere the characteristics of just can solve the above problems.Therefore,in this study,we propose to apply micro-class to improve the ability of high school students to build physical models.Its main content is divided into four aspects: First,through the literature review of previous research results,to explore the theoretical basis of this study,collate the definition of the relevant concepts of this study,to determine the easibility of the study.Secondly,analyze and sort out the model and classification of physics and mechanics in senior highschool.Thirdly,it puts forward the design principle and operation flow of Microlesson to improve senior high school students' ability to construct physics model.Fourthly,a practical microlesson case is made for different types of models.The purpose of this study is to provide an alternative way for educators to cultivate and improve the ability of high school students to construct physical models.At the same time,it is beneficial for learners to form scientific thinking in the learning process.
