Virtual Experiment R & D Based On Vr-Platform In High School Physics Education

The rapid development of Computer technology and broadband network not only changed the way people lived and worked,but also produced unprecedented influence on people's learning. Moreover,the emerging of various Computer-assisted learning software and Internet education benefits the teaching process of teachers and the learning process of students as well greatly. Along with development of user-friendly Computer software technology and high-level programming languages,the experimental teaching also gradually moves toward virtualization. All of these can be seen that there not only emerging various multimedia coursewares,but also many different kinds of virtual laboratories appearing on the network. However,these virtual laboratories are mostly two-dimensional scene,which decreased the students'third dimension of participating in the experiment,thus,affecting the function of promoting students'learning. Virtual laboratory,the imitation of real experiment scene in essential,is the almost lifelike appearing of the experiment which has limited experiment condition or which unable to realize in the real laboratories. It should have the same physical properties with the real laboratory, and students in it should have the similar experiencing and the same learning effect as in the real laboratory. Therefore,virtual laboratory may be able to satisfy students for independent exploratory operation,of which the two-dimensional virtual laboratory is unable to realize,but not the virtual third dimension laboratory scene.Based on the comprehensive analysis of the development condition of domestic and international virtual reality technology and virtual laboratory,we found that the study on middle school physics experiment teaching of third dimension virtual experimental studies are relatively few. So,the thesis takes the middle school physics as an example to describe the way of creating third dimension virtual laboratory in detail.The thesis starts with the analysis of current situation of middle school physics experiment teaching,putting forward the necessity of reform middle school physics experiment teaching model; Then,based on the comparison analysis of the virtual laboratory and virtual reality technology development condition at home and abroad,we choose the 3DMax and VR - Platform as the technology support of this virtual system;Through the analysis of relevant learning theories,the autonomous learning theory,the inquiry learning theory and cognitive socialist theory can be used as the theoretical foundation; Upon the learning condition analysis and considering the Senior High School physics Curriculum Criterion,we determined the function requirements,experiment modules and working process of virtual experiment;the fifth part of the thesis focus on the development process of this virtual experiment,the explanation of operation procedure and the assessment of the effect;Finally,we summarizes the shortages existing in the study,and puts forward suggestions for future research.
