With the continuous development of information technology, which make thenew technology of virtual reality technology is maturing, improve and continue topermeate all kinds of areas,its application in the field of education has also beenwidespread concern of educators. In response to the shortcomings of the currentexperimental teaching, the teaching and application of virtual experiment to acertain extent to improve the present situation, so the study that the build of virtualexperiment and the teaching way of virtual experiment in junior middle schoolchemistry is very necessary.In the present study, the design and teaching applications of virtualexperiments as a starting point to analyze the status of junior middle schoolchemistry experiment teaching and the teaching status quo of virtual experiment injunior middle school chemistry experiment, and it as a basis to explore the newideas on the combination of virtual experimentthe and junior middle schoolchemistry teaching. Under the guidance of the theory of constructivism, situatedcognition, we explore the process of build a virtual junior middle school chemistryexperiment by using3D modeling,3D interactive technology and other relatedtechnologies to, and to the junior high school chemistry experiment potassiumpermanganate preparation of oxygen experiment the development of the object ofthe virtual experiment to study the process of constructing. Finally, the virtualexperiment used in junior high school chemistry experiment, a specific pattern toexplore applied to teaching activities, and feedback through questionnaires virtualexperiment into the chemistry experiment teaching effectiveness.After the theoretical study and practical research results show that: virtualexperiments can be used as teaching aids and new forms of teaching used inteaching, interesting, situational characteristics can stimulate learners’ interest inlearning, and making experimental teaching more vividlively. Virtual experiment inteaching can help learners to deepen the understanding of the experimental content, and to strengthen learners grasp on the experiment repeated operation of theexperiment, which training learners ability and self-learning ability. We should alsoclear that the virtual experiment is not a substitute for the real experiment, but towith real experimental compatible play their strengths to the role of teaching, notonly to make up for the lack of experimental teaching to some extent, but alsoprovides a new way to experimental teaching methods, so as to enhance thechemical experimental teaching efficiency. |
