Design And Development Of Courseware On Experimental Education Based On Virtual Environment

In the education, the experimental teaching is one kind of is direct-viewing and the image method, through the experimental method, it can abstractly and specifically demonstrated process of the people knew and discovered some knowledge, the principle, lets the student understand, know and grasps some knowledge ,the principle in a shorter time, and for grasping other knowledges to building the foundation. At the present, teaching condition still has certain flaws and the objective reason that its the variety, the complexity, the isolation and so on, it is impossible that each experiment all to apply in the teaching and lets the students really complete each experiment. Moreover, at present, in the experiment education procession, the students lack of the practice ability to the certain degree. In order to understanding these which the design and operation with difficulty completes as far as possible in the teaching process to students, we usual use fully,reasonably, effectively multimedia teaching courseware so that saves the teaching time, and reduces the experimental teaching ,and enhance its experimental teaching efficiency and the quality.At the same time, along with the development of society and technical progress, the people proposed the new request to the man-machine interactive way among teaching courseware, except multimedia method which already widely use union of multimedia technical, network communication technical that based on the Internet. The people explore most technology were "the virtual world" that are highly life like and interactive give the person by the body near its scenery, which union production of the multimedia technology and virtual reality, simulation technology, graph technology and so on. So many users have realized"immerse"commonly in a virtual environment in the different physical location so that realize mutual exchange between freely roams and users. This technology will apply to the development of experimental teaching class in order to promoting further implementation of the experimental education, the article will be further research by the views.At first ,the author has analyzed theory foundations, questions and the development tendency of the experimental educations, has searched the virtual reality technical characteristic as well as how to establish the virtual environment, also has studied the three dimensional scene modelling and alternately realizes of the technology, analyzed and compared with the modelling technology of development, the realization of the geometry modelling, the movement modelling, the object modelling and so on. In addition, it discussed realization of interactive function in virtual reality, including realization interactive function that the script language and the Virtools tools, and according to characteristic and the function of experimental teaching and virtual reality technology construct the virtual environment, applies the virtual technology to designing and developping the courseware.Finally, I unified model experiment of the educational technology -- computer multimedia projection teaching system, has used the 3DSMAX modelling and Virtools to carring on realization of the behavior interactive functions, founded experimental education courseware that based on the virtual environment, and reconsidered the questions and the insufficiency in the topic, proposed the improvement method and the research plan next time.
