A Study On The Virtual Experiment And Its Teaching Management Platform

With the high development of information technology, the traditional education pattern is being challenged. A new education pattern, namely, modern distant learning is being developed quickly, with a unique function;more attention has been given to distant learning. Similar to the traditional education, there are both theory teaching and experiment teaching in modern distant teaching. In terms of theory teaching, courses are conducted through distant multimedia, while in experiment teaching, experiments must be done by students themselves. Contrary to theory teaching, the experiment teaching is not distant and face-to-face at all. Thus, there is a mismatch between experiment teaching and distant theory teaching pattern. However, the solution to this problem is possible because of high technology, especially these such as computer simulation, AI, VR, Multimedia programme design, and so on. In addition, there appear some special tools developed for designing and developing virtual experiments. They are very useful in developing virtual experiments and well applied in product design and promotion. However, due to the special features of teaching, how to apply this technology to experiment teaching still remains a challenging subject for us.The virtual experiment can be defined as the computer simulated experiment, which is based on certain computer platform and realized with the support of hardware and software. As the enforcement and extension of the traditional experiment, and the direction of experiment teaching development, the virtual experiment is the combination of multi-medium computer technology, network and VI. Virtual experiment teaching widening the time and space;being student-centered;decreasing the financial investment;enriching the content and activating students in learning with its virtual situation and experimental environment. In addition, some of virtual experiments can avoid the dangers encourted in real ones. The development of virtual experiment technology gives a support for experiment teaching reform and provides a good method for experiment teaching in distant learning.Starting from the problems in education and the present situation of virtual experiment teaching.this thesis made a total design on the virtual experiment teaching platform, developed and conducted a virtual experiment based on the relevant theories on virtual experiment. Based on the analysis on concept, history and theories of virtualexperiment, the thesis develop a virtual experiment teaching management platform based on network electronic circuit and virtual experiment. Then, combined with Multisim, a decoder virtual experiment is conducted, finally, the direction of the virtual experiment development and the limitation of the thesis are stated.In the introduction of virtual experiment, its basic concept, historical development and theoretical basis are provided. In the design and realization of electronic circuit virtual experiment, it is stated that some problems in forming a network-based virtual experiment platform can be solved with the relevant programme of Multisim7 from Canadian Company-Interactive Image Technologies, Multisim7 is a construction programme on client software electronic virtual experiment teaching management platform. Also, it provides some management strategies on online and offline experiments and gets rid of the problems between virtual experiment and net transmission. Aimed at open experiment teaching and centered on students, the main contents of virtual experiment teaching are followed: administrator modal, teacher management and evaluation modal, student learning and experiment preparation modal, as well as guest modal. With the platform, students can learn how to use the components and parts, know the requirement of virtual experiment, download virtual software, do the experiment according to direction, upload the experiment report, and participate in the discussion etc. m the practices and reflection of electronic circuit virtual experiment, based on the theories on electronic circuit experiment, the thesis analyzed the guiding principles and teaching pattern design of virtual experiment and finished the decoder experiment in digital circuit with Multisim7 combined with the existing experiment teaching management platform. Base on that, the limitations and suggestions for improvement are provided.
