Research And Realize On 3D Middle School Physics Virtual Experiment

Experiment is an important part of school physics education, In traditional middle school physics experiment educational model, because of the limited time, place, equipment, students lack the spirit of creativity, the status of experiment education is relatively low, the interactive teaching resource is in shortage in experiment education. Judging from the tendency of new course standard and establishment educational reformation, the virtual experiment education which based on computer is an important developing tendency. Compared with traditional experiment educational model, virtual experiment resolves the shortage of funds, make real operation safer, and completely breaks the limitation of time, place and equipment, Meanwhile strengthen the student's creative capability in experiment. In this paper a new model and method of middle school physics experiment education is proposed, which is combining with computer three-dimensional graphics handing technology and educational theories. Three theories are applied in this paper, which is situation learning theory, distributing cognition theory, constructivism theory. Meanwhile the learning framework, situation atmosphere, main principle of virtual experiment technology are analyzed. Finally the two level structure of middle school physics virtual experiment is established, that is the function structure of first level experiment and playing learning part, the function structure of second expand experiment. In addition, the learning content and function structure are abstract to the educational model in practice by EML educational modeling language.Compared with several main virtual technologies in the world, the technology of the program is realized by 3DMAX and VIRTOOLS. That is, constructing the 3D experiment scene and creating the 3D animation with 3DMAX; processing and interacting on the experiment data with VIRTOOLS. Through playing the teaching and learning operate process of example, the advantage of self-learning, intelligent interact, interest attracting are fully appeared.
