【摘要】：随着高等教育信息化的迅速发展,虚拟网络教学作为一种新的教学模式,正迅速的发展并得到越来越广泛的应用。其具有丰富的多媒体资源、便捷的协同交流、友好的互动等独特的优势。实验教学作为机械学科教学的重要部分由于各大高校实验室设备参差不齐,实验成本相对较高等劣势,在各大高校中还不能一致达到较好的教学效果。基于网络的虚拟实验教学平台有效地解决了这一问题,通过该平台,可以开发出复杂而又实用的先进设备,让学生形象深刻的了解设备中机构的运动原理,掌握知识本身;另一方面,该平台很好的解决了学生学习时在时间和空间上的局限性。本文在分析虚拟实验国内外发展状况,通过对各种学习理论的对比和各种虚拟现实技术研究比较后,针对机械学科的特点,基于人本主义学习理论和新媒体理论,提出了两套解决方案,分别为基于EON的VC++技术和基于Flash的Flex技术,开发出一套针对机械学科的基于网络的虚拟实验教学平台,将对设备的自主观察、自主拆装,自主规划连接,三维仿真,自动对相应运动进行计算分析的技术集成于一体,具有可视化,交互性强,可扩展可开发等多种优势。目前该虚拟实验平台已经运用到实际教学过程中,通过教师和学生使用反馈,经过不断完善和改进,虚拟实验平台最终将得到了实际运用。
[Abstract]:With the rapid development of information technology in higher education, virtual network teaching, as a new teaching mode, is developing rapidly and being applied more and more widely. It has rich multimedia resources, convenient cooperative communication, friendly interaction and other unique advantages. As an important part of mechanical teaching, experimental teaching has not been able to achieve better teaching effect in colleges and universities because of its uneven laboratory equipment and relatively high experimental cost. The virtual experimental teaching platform based on network solves this problem effectively, through this platform, can develop the complex and practical advanced equipment, let the student understand the movement principle of the mechanism in the equipment image deeply, master the knowledge itself; On the other hand, the platform solves the limitation of time and space. This paper analyzes the development of virtual experiment at home and abroad, through the comparison of various learning theories and virtual reality technology, according to the characteristics of mechanical disciplines, based on the humanistic learning theory and new media theory. Two sets of solutions are put forward, which are VC technology based on EON and Flex technology based on Flash. A virtual experimental teaching platform based on network for mechanical subject is developed. The technology of autonomous planning, 3D simulation and automatic calculation and analysis of the corresponding motion is integrated into one, which has many advantages such as visualization, strong interaction, extensibility and development. At present, the virtual experimental platform has been applied to the actual teaching process, through teachers and students to use feedback, through continuous improvement and improvement, the virtual experimental platform will eventually be used in practice.
