X3D论文：基于X3D探究式虚拟学习环境的设计与开发 【中文摘要】随着计算机图形图像技术的快速发展,虚拟技术广泛应用于各个领域,近几年逐渐发展起来的X3D技术标准,使用可扩展的标记语言XML表达,使用严格一致的数据编码格式,组件化结构,强大的网络功能、多媒体功能、人工智能和动画设计等多种高级功能进行开发和设计。它给虚拟技术的网络传播和各领域应用提供了的新思路和新方向,其在教育中的应用地位日益凸显。科学研究活动是小学《科学》学科的核心和精髓,它突出学生学习的体验性和探究性,对于类似动物的进化等学习内容的信息承载与表达,传统媒体相对捉襟见肘。而把此学习内容和X3D技术标准进行规划和整合,则两者相得益彰,既解决了小学生抽象信息认知的障碍,又突破了现行教具无能为力的瓶颈,从而轻松实现教学重点和难点的突破。本文研究的就是以X3D虚拟技术为支持,解决类似学习方面的问题、模式和策略等。本文以现代虚拟技术和探究学习理论为根基,从X3D虚拟技术的建模、交互等基础功能出发,结合探究学习理论,并应用SCORM和MOODLE等学习工具和平台,研究适合小学生学习内容抽象、年代久远等学习内容的教学模式和学习策略等。通过实验调查发现,运用本文提供的模式和策略进行小学科学教学,有利于小学生科学兴趣和探究能力的提高。 【英文摘要】With the rapid development of computer graphics technology, virtual reality technology is widely used in various fields in recent years. X3D technical standards developed gradually use XML of extensible markup language to express, data of rigorous and consistent format to encode, and structure of component-based and powerful networking capabilities, multimedia features, animation and other artificial intelligence and advanced features for design and development. It is becoming more and more prominent in education practice that provides new ideas and new directions with network dissemination of virtual reality technology and application of various fields.Scientific inquiry activity is the core and essence of scientific subject in primary school, which highlights the experience and inquiry. For the similar contents as animal evolution, traditional media is difficult to express and load the book information. But the planning and integration X3D for the learning and the standards make each other get a benefit, which not addresses the barriers of abstract information understanding in primary school, but also breaks the bottleneck of the existing teaching aids in classroom. So the key and difficult of teaching is easy breakthrough. This next research will solve the similar problems based X3D virtual technology in models and strategies.This paper based on virtual reality technology and inquiry learning theory, such as X3D mode
