The Research On Design And Application Of Verifiable Virtul Enviroment On Junior School Chemistry

Educational Technology development in terms of theory and technical aspectsof fundamental improvement,to achieve the modernization of education,educationinformationization is an important foundation, using information technology to boostthe development of the modernization of education and the future development ofeducation.The rapid development of computer technology, modernizational equipmentwhich was introduced to the education promotes the optimization of development ofthe teaching environment.In this backdrop, the virtual experiment system came intobeing. Wide range of applications of virtual reality technology, making the speed oftransmitting information has greatly improved,and the teaching process has alwaysbeen the transfer of information.understanding the absorption process. Therefore,make virtual reality be popularity in the field of education is the trend of today’seducation.Most of the teaching in chemistry must rely on experiment, but due to a varietyof factors led to the current education environment can not satisfy thestudents’experiment needs, coupled with the dangerous in experiment,most ofstudents must to read experiment and remember experiments.By the virtual design ofjunior school chemistry experiment,keep the experiment showed in a virtual way, toexclude the real experiment can not be achieved and the possible risks, and to retaina positive experiment, safety factors.First of all,refer to literature on the application of virtual reality technology ineducation at home and abroad in recent years,summed up the key and difficult pointsof virtual chemistry experiments,the problem has been resolved.Then analyze thetheoretical studies on the use of virtual reality technology in the teaching ofchemistry experiments,including the overall goal of the high school chemistryexperiment teaching, learner analysis,learning needs analysis,analysis and evaluationof teaching objectives, teaching design results evaluate and optimize the designprinciple of the virtual lab environment, learners cognitive and affective interactiondesign in a virtual environment.Secondly,after study and research analysis of ninth-grade students’ way of thinking,learning,behavioral and operational ability,combined with the basiccharacteristics of the junior high school chemistry, and a difficult case (carbonsingle-mass reduction experiments of the copper oxide), take a teaching design anddevelopment on the virtual experimental, a junior high school chemistry validationof case-based virtual experimental system.Important part of this study is theaffective interaction, full control of experimental conditions into the system.The advantages of virtual reality technology will give the experimental subjectsin the education and efficient,the new learning methods,learning environment.
