【摘要】：在科学技术快速发展的今天，计算机技术、网络技术和通信技术为代表的现代信息技术在教育领域已经开始广泛应用。在传统教育的过程中，理论知识的学习与实验技能的提高之间的矛盾越来越突出。虚拟实验在这种环境下应运而生，它丰富了实验教学的内容，提高了实验教学的理论体系。本文首先通过互联网搜索的方式对虚拟技术国内外的研究现状进行梳理，同时考察了大学物理实验教学现状的基础，分析开发大学物理虚拟实验的必要性，在结合大学物理的实验特点，确定采用VRML技术进行开发；其次分析了虚拟实验设计开发的理论基础，分别阐述了混合式学习理论、情景式学习理论、自主学习理论的内涵、特征以及对虚拟实验的支持；然后分别从功能、工作原理、浏览器和编辑器这几个方面对VRML语言进行详细介绍；最后VRML与Java技术的结合设计出光的偏振、单缝衍射的虚拟实验。论文共包括六章，，在第一章中分析了虚拟技术在国内外的发展应用，指出了大学物理实验教学信息化的必要性；在第二章中分析了虚拟实验的概念、类别、发展历史和特点，以及在教育中的应用。第三章研究了用于设计虚拟实验的多种虚拟现实技术（VRML、Java等)，提出了利用这些技术制作大学物理虚拟实验的观点；在第四章中，设计了实用的大学物理虚拟实验系统，并以光的偏振虚拟实验为例，详细地分析了该实验的概要设计及详细设计；第五章描述的是大学物理虚拟实验系统的实现，以光的偏振虚拟实验为例详细地阐述了该实验各模块的开发过程，同时介绍了实现大学物理虚拟实验及虚拟实验室的关键技术；在第六章中对研究工作做了总结和展望。本研究成果为改进虚拟实验教学提高实验效果，尤其对现实中学生多、仪器少或者难以直接实现的实验项目，提供了一条有效的解决方案，促进实验教学的网络化和现代化具有现实意义和实践意义。
[Abstract]:With the rapid development of science and technology, modern information technology, represented by computer technology, network technology and communication technology, has been widely used in the field of education. The contradiction between the learning of theoretical knowledge and the improvement of experimental skills is more and more prominent. Virtual experiment emerges as the times require in this environment, which enriches the content of experimental teaching and improves the theoretical system of experimental teaching. This paper firstly combs the research status of virtual technology at home and abroad through the way of Internet search, and at the same time, investigates the basis of the current situation of college physics experiment teaching, and analyzes the necessity of developing virtual experiment of college physics. In combination with the experimental characteristics of college physics, VRML technology is adopted to develop. Secondly, it analyzes the theoretical basis of the design and development of virtual experiment, and expounds the connotation, characteristics and support of the virtual experiment, including the mixed learning theory, the situational learning theory and the autonomous learning theory. Then the VRML language is introduced in detail from the following aspects: function, working principle, browser and editor. Finally, a virtual experiment of polarization and single slit diffraction is designed by combining VRML and Java technology. The thesis includes six chapters. In the first chapter, the development and application of virtual technology at home and abroad are analyzed, and the necessity of informationization in college physics experiment teaching is pointed out. In the second chapter, we analyze the concept, category, development history and characteristics of virtual experiment, as well as its application in education. Chapter three studies several virtual reality technologies used to design virtual experiment, such as VRML. Java et al., put forward the viewpoint of using these techniques to make virtual experiment of college physics. In chapter 4th, a practical virtual experiment system of college physics is designed. Taking the polarization virtual experiment of light as an example, the outline design and detailed design of the experiment are analyzed in detail. Chapter 5th describes the realization of the virtual experiment system of college physics. Taking the polarization virtual experiment of light as an example, the development process of each module of the experiment is described in detail. At the same time, the key technologies to realize the virtual experiment and virtual laboratory of college physics are introduced. In chapter 6th, the research work is summarized and prospected. The results of this study provide an effective solution for improving the virtual experiment teaching and improving the experimental effect, especially for the experimental projects which have more middle school students, less instruments or are difficult to realize directly. It is of practical and practical significance to promote the networking and modernization of experimental teaching.
