【中文摘要】建构主义学习理论夸大在真实的教授教养情景下,入行有意义的探索与发现,从而完成新知识在固有的知识构造上的建构。在传统的教育模式中,学习者去去依据课本或者老师提供的信息被动的接受间接的知识经验,不仅对知识缺少直观形象的理解,也缺少实践的机遇。而建构主义学习理论倡导学习者在教师的引导下入行基于场景和题目的研讨性学习,在学习者对知识入行学习的同时,培育其发明性思维和解决题目的才能。虚拟现实技术做为一门新兴的技术类学科,它在教育教授教养中的应用从一开始就受到广大教育学者的认可。尤其是其能发明真切的学习场景、并为学习者提供与场景良好的交互等特色,恰能符合研讨性学习中对学习环境建构的需求。虚拟现实技术应用盘算机三维图形技术、交互技术、模拟技术、传感技术、人机界面技术、显示技术等技术手腕,为学习建构一个仿真的学习环境。在这种虚拟的学习环境中,学习者通过与学习体系或是与其他的学习者入行交流与合作,获得真实的认知体验,从而完成知识的建构。尤其是在研讨性学习中,应用虚拟现实技术来开发设计虚拟学习环境,既可认为学习者提供一个真实的学习环境,战胜研讨性学习受到场地、时光等因素的限制,又可以消除其他对学习不利的影响因素,因而研讨虚拟现实技术在研讨性学习中的应器具有主要的现实意义。本文中首先介绍了虚拟现实技术的基本概念和主要应用范畴,入而对海内外研讨现状入行剖析和比拟,然后讨论在建构主义学习理论指点下的研讨性学习对学习环境的需求,从而体现出虚拟现实技术在研讨性学习中应用的优势。最后通过设计开发熟习树叶虚拟学习体系,来探讨应用虚拟现实技术开发研讨性学习场景的详细入程。本研讨主要完成以下三方面的题目:第一,虚拟现实技术的定义、来源、发铺与应用。并通过对比海内外有关虚拟现实技术及应用的现状,来剖析当前研讨虚拟现实技术的研讨方向与研讨中所应该留意的题目。第二,虚拟现实技术在研讨性学习中的应用设计。通过讨论在建构主义学习理论支持下的情景学习在教授教养中的应用,入而研讨虚拟现实技术中在研讨性学习中应用的优势,再结合详细的案例,说明虚拟现实技术在研讨性学习中的应用方式。第三,虚拟学习环境的开发与应用研讨。对虚拟学习环境入行剖析、设计与开发,并对设计结果入行应用评价,体现虚拟现实技术在研讨性学习中应用的意义。');
【Abstract】 Constructivism learning theory emphasizes meaningful exploration and discovery in a real circumstance, doing this to construct the new knowledge on the knowledge that the learner have had. In the traditional mode of education, the learners often study based on textbooks or the information from teachers. They learn passive knowledge indirectly. The result of this is that the learners are not only lack of intuitive understanding of the knowledge, but also lack of practice opportunities. Based of the constructivist theory, the learners should better have a scene-based study or problem-based study under the guidance of teachers, so that at the same time of learning knowledge, they can develop their creative thinking ability and problem-solving abilities.Virtual reality technology as a new technology subject, its application in education and teaching from the beginning on is recognized by the majority of scholars. In particular, it can create realistic scenes, and providing learners with the scene of the interactive features, these characters are just to meet the problem-based study on the demand for construction of the learning environment.Virtual reality technology use 3D computer graphics technology, interactive technology, simulation technology, sensor technology, human-machine inte***ce technology, display technology and other technical means, in order to build a simulation study of the learning environment. In such virtual learning environment, learners communicate and cooperate with the learning system or with other learners, obtain real cognitive experience and complete the construction of knowledge. Especially in the problem-based study, use virtual reality technology to develop a virtual learning environment for learners can provide them a real environment fact. In this way they can overcome the difficulties on the venue and time or other factors can have a worse effect of the learning in the course of problem-based study. So study of using virtual reality technology in construction a problem-based study environment is very valuable.This article first introduced the basic concepts and major applications of virtual reality technology, and then analysis of the status quo of domestic and foreign. Next by we discuss the constructivist theory, the problem-based study under its guidance needs a real learning environment in order to show the advantages of the virtual reality technology. Finally, we develop a virtual learning system of cognizing the leaves, to explore the use of virtual reality technology in problem-based studyThe purpose of this study include the following three aspects.Firstly, the definition, the origin, development and application of virtual reality technology. And by comparing the status quo of the domestic and foreign in virtual reality technology and applications, we related to an analysis of the problem we should pay attention in current virtual reality technology study.Secondly, how virtual reality technology is used in the problem-based study. Through discussion the scenario-based teaching and study under constructivist learning theory, we search the application of virtual reality technology to construct a learning environment for problem-based study. Third, the development and applied research of construct a virtual learning environment. We discuss the development of the process of analysis and design, application and evaluation of design results of virtual learning environment, so that to reflect the meaning of the application of virtual reality technology in teaching.
