Application Of Graphic Representation In Physics Teaching In Senior High School

Graphic representation is a graphical representation of information,which is manifested and stored,mainly through function images,photos,sketches and other forms.According to human visual cognitive characteristics,when complex information and intuitive information appear,human visual cognitive system will give preference to visual information.,graphical representation can span many complexinformation ion,directly on the characterization of characterizing the object information.In high school physics teaching,graphic representation is an important way to form physical concepts and laws,and also an important way of thinking to solve physical problems.The thinking mode of high school students is in the stage of gradual transition from concrete image thinking to abstract thinking.At this time,the formation and development of abstract thinking ability depends on the intuitive representation thinking.According to human visual cognitive characteristics,when complex information and intuitive information appear,human visual cognitive system will give preference to visual information.Therefore,in physics teaching,the application of intuitive graphical representation is more conducive to students'understanding of abstract physical concepts and physical laws.According to cognitive learning theory and color perception theory,in the process of graphic representation,intuitive information to get the corresponding cognition,must meet can lead to sex,statement of significance,semantic significance three conditions.Therefore,in the high school physics teaching,in order to apply the graphical representation method more effectively,we also need to satisfy these three conditions.In order to satisfy the three conditions,according to human visual sensitivity to the different color is different,this article obtains from the people of color perception level,investigate the perception of the color of the high school students,through the theoretical analysis of the survey graphical visualization of two conclusions.Conclusion 1:in order to make the graphical representation more intuitive,the tools to represent the information to carry the information need to be perceptually significant.If color contrast is used to indicate the concept of differentiation,then visual contrast is required.Conclusion 2:in the graphic representation,it is more consistent with the cognitive habit of human beings to understand the information of the represented object.In this paper,in accordance with the theoretical analysis,the conclusions to ask two difficulties in the high school physics:artificial earth satellite launch its problems and spring in compression and tensile elastic potential energy change.The feasibility of implementing the strategy of graphical representation is verified through the effectiveness test of teaching design scheme and questionnaire survey.
