Research And Design Of Virtual Junior High School Chemistry Experiment Based On Virtools

With the improvements of computer and virtual reality technologies, virtual experiment technology is recognized and being developed rapidly. The education and teaching reform continuously and increasingly puts new demand on teaching experiments to develop research ability and comprehensive quality of students. Teaching content, teaching form and teaching method of teaching experiments urgently needs to be reform and improvement. These make the virtual experiment undergo a dynamic process from theoretical research to practical application. The virtual experiments not only can reduce the experimental cost enormously, but also can promise numerous students share experiment resources without the time and space limits. It is the beneficial auxiliary method of teaching experiments.The thesis first discusses the research background, purpose and the significance, analyzes the study status at home and abroad; make a further discussion on the theoretical basis, the meaning, characteristic, classification, the technical background and the development direction of virtual experiments; make a introduction and comparing analysis to the implementation technology; analyzes the characteristic and the existing problems of the chemistry teaching experiments in the junior middle school; Take junior middle school chemistry experiment"The oxygen producing in laboratory"for example to develop the chemistry virtual experiment with VIRTOOLS,MAYA. It introduces the main function module of the system and the key technology, and Discussion and summary about the development method of virtual experiment.At the end of thesis, considering the experience in the development of system and the deficiency of system,simply making an outlook for the further research on the field.
