《现代教育技术》虚拟实验室的设计与开发

Constructing and Realization of Virtual Lab for Modern Educational Technology

虚拟实验丰富了实验教学的教学模式和学习方式，为实践教学的创新提供了新的平台和拓展空间。结合国家精品课程《现代教育技术》的建设，以认知科学及建构主义学习理论为基础，提出了利用虚拟现实及多媒体技术构建虚拟实验室的开发方案，并对系统的开发流程进行了探讨，在此基础上采用Virtools技术设计了虚拟实验室原型。最后以实例描述了虚拟实验开发的关键技术。

Virtual experiments enriches the teaching modes and learning methods in experimental teaching pratices； supplies new platforms and developing spaces for practical teaching. With the combination of the development of national high-grade curriculum ， constructing methods of virtual lab from virtual reality and multi-media techniques are offered on the basis of cognitive science and constructivism theory， the constructing flow of the system is also discusses， original virtual lab shapes are constructed on vritual techniqes successionly. And last several illustrations are presented to demonstrate the key techniques of constructing.
