The Teaching Research Of Function Image Method In The Experiment Of Mechanics And Electrical Physics In Senior High School

Function image method is a kind of visual and intuitive representation method,which can clearly reflect the relationship between different physical quantities.In physics teaching,the function image method is not a direct transfer of function images in mathematics because the process of transfer process needs to avoid excessive mathematical-Through analysis,the reason why the students' function image application ability is not strong is that the physical scene cannot be abstracted from the intuitive function image.If the acquisition of each type of function image is abstracted from the physical scene experience,then students will stereoscopic function image,and make the ability of distinguishing function image method and function image stronger.Therefore,this thesis will carry out teaching research on functional images in physics experiments.Through theoretical research and empirical investigation,this thesis expounds the feasibility and necessity of cultivating students' ability to apply functional image method in the teaching of physics experiments in high school.By analyzing the function images in the textbooks and the college entrance examination experiments,the significance of cultivating students' ability to apply function images is discussed.In the meantime,the vertical and horizontal analysis of each physical experiment is made in detail,and the requirements and ability cultivation of function images and the advantage of physical function image method in Physics Teaching for each experiment are summarized to prepare for the case design.Secondly,on the strength of the content of the textbook,the requirements of the new curriculum standards on the core quality of physics and problems in students' cognition,based on Bruner's structure-discovery theory,we designed "inquiry about the relationship between work and speed changes" and "measure power EMF and internal resistance" two experimental cases.Finally,by doing the comparative experiments of "determining the electromotive force and internal resistance of the power supply" and the evaluate it,we found that through the unit preparation,the teacher presented more experimental materials and clues encouraged the students to make more assumptions and attempts,which could cultivate students' scientific literacy,helps students to integrate problems,and enables them to have a rigorous and serious scientific attitude.Meanwhile,gradually cultivate students'ability to three-dimensional function images,and realize the positive transfer of function images from mathematics to physics.
