Research On Application Of Virtual Experiment In The Teaching Of Middle School Physics

With the improvement of computer and modern educational technologies, virtual experiment technology is rapidly developed and being widely used. The virtual experiment, which is considered as the third research method following theoretical and experimental investigation, shows an important direction for the scientific research technique. Moreover, it also plays an increasing role in social development and science and technology at present.Experimental teaching, for example, teaching content, teaching mode and teaching method, needs to be innovated and consummated because a higher requirement on the ability of scientific research and diathesis of students has been recently presented from teaching innovation. The latest development of the virtual experiment technology and strong demands of experimental innovation make the virtual experiment undergo a dynamic process from theoretical research to practical research. Based on this, this paper explores a system of virtual experiment and applies it into practice in the teaching of physics.The paper introduces the development of virtual experiment around the world, then analyses the theoritical basis of it, such as constructivism, blended learning and interactive theory, and its technological base. The paper elaborates the entire process of virtual experiment's system from its design to realization in details. Middle school physical experiments, which are typical in the present middle school education, have been choused as the research object of the virtual experiment instruction and analyses the application result. On the one hand, the application of virtual experiment in helping experimental teaching by teachers. The teaching mode and its teaching design have been discussed. A project named as"the convex lens image formation and the camera"is well designed and applied in the teacher's optics teaching. Meanwhile the virtual experiments have been utilized by the teacher to break through the difficulty in physics teaching and gives cases accordingly. On the other hand, the application of virtual experiments in helping"inquiry-based learning autonomy", the studying mode and the teaching design have been discussed. A project named as"the question of the electric circuit short"is well designed and applied in the inquiry-based learning autonomy. Meanwhile, it attempts to well integrate the virtual experiments and real experiments in order to help students with inquiring experiments and gives cases accordingly. The analyses of both aspects'application effect shows that with the help of virtual experiments, the quality of instruction can be improved and the capability of student's auto-inquiry can be better developed.Finally, we summarized the virtual experiment research work in the middle school physics teaching, and proposed further studies direction.
