The Design And Development Of Virtual Experiment Based On3DMax And VRP

With the promulgation of the Decade Development Plan (2011-2020) on theEducational Informationization and the implementation, nowadays one of the hot is todesign and develop the virtual experiments. And the virtual experiments have beenused widely in education at present. From the physical three-dimensionaltarget, it emphasizes the process and method, and emphasizes that the students shouldexperience the process, observe the experimental phenomenon through theexperimental operation, and draw the conclusion of the experiment. Using the threedimensional technology--3DMax and VRP technology to design anddevelop the virtual experiments, on the one hand, it can cultivate and improve thelearners’ study ability and the experimental operation ability; on the other hand, thegood realistic of the experiment scene and experiment models can make the learnersthe stronger immersive-feeling and the multi-sensation.At first, this paper analyses the present research situation of the inquiryvirtual experiment, and obtains the necessity to study the inquiryvirtual experiment based on the3DMax and VRP; Then according to the2013juniormiddle school physics new curriculum, taking the junior middle school physicsexperiment teaching as an example, analyzes the function and position of inquiryexperiment in junior high school physics, and choose the research object thatto explore the effecting factors of friction as an example. In this study, taking thetheory of the inquiry learning, the theory of the blended learning, the theory of theflowing and so on as its theory basis, taking the3DMax technology and VRPtechnology as technical support, to design and develop the virtual experiment;Between them, mainly using the3DMax technology to construct experimental modelsand the experiment scene,including the part of the texture effect of theexperimental models and experiment scene，while mainly using the VRP technologyto realize the interactive function and the experimental scene of scaling androtation effects in the virtual experiment, and modify the part of experimental modelsand the texture effect of the experimental scene. Finally, this research select thestudents and physics teachers at middle school in Qingfeng County as the object of investigation and study, to explore and analysis the actual situations ofthe virtual experimental. Through the analysis of survey data, the author found thatthe majority of teachers and students accept the virtual experiment of thisthree-dimensional technique, and they think that the virtual experiment has thestronger interaction and the experimental scene has the good fidelity, and it can beable to meet the learning needs of learners. But some teachers think that thisvirtual experiment has not formed a complete system of experiment—a complete setof Virtual experiment system, only rely on a simple virtual experiment to improvelearners’ inquiry ability also exist some problems, and to modify the virtualexperiment of color technology, the effect will be better and better, and thisvirtual experiment still need further improvement and amendment.
