Design And Develop Of Virtual Reality Technology In Program-Based Learning

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 interface 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.
