网络教育的优势使它成为现代教育技术研究的热门,各种网络教育支持系统应运而生。虚拟教室是以建构主义理论为基础,利用计算机多媒体技术、网络技术、现代通讯技术等构建的数字化网络教育支撑平台,为网络教学提供了一种新的组织形式。 课题的研究工作主要针对虚拟教室的概念、虚拟教室学习环境的组成、虚拟教室的功能结构和设计开发模型等方面展开。在内容上,论文包括四部分:第一章,论述了网络教育支撑平台,并分析了虚拟教室研究的必要性。第二章,给出了虚拟教室的概念,论述了虚拟教室发展演变过程与类型划分。第三章,首先探讨了虚拟教室设计的理论基础和学习环境的构成要素,然后从教师、学生和管理员三个角度设计了虚拟教室的系统功能,得出了其功能结构图,并描述了在系统中进行教和学活动的流程。最后概括了虚拟教室系统的设计开发模型。第四章,介绍了虚拟教室部分子系统开发的实现技术和使用方法。 整个研究的特色体现在:科学地界定了虚拟教室的概念:以传统教室为原型,以课堂教学过程为依据设计虚拟教室的功能结构,并使之成为可承载各类网络课程的教学平台;以低成本、低难度、高效率的开发理念指导虚拟教室开发实践。本研究工作为各类教学平台的开发及推广应用提供了一定的参考依据和借鉴经验。
Web-based education has become a hot research of modern educational technology by reason of the advantage. Various support platforms of web-based education emerge as the times require. The virtual classroom takes constructivism as foundation and utilizes computer multimedia technology, network technology, modern communication technology and so on to structure a digital platform that supports web-based education, it offers a new organizational form for web-based teaching.The main study includes (?)esearching the virtual classroom"s definition, the constitution of web-based virtual classroom"s learning environments, structure of function, and the model of designing and developing. The content of the thesis includes four segments. The first part of the thesis describes the support platform of web-based education, and analyses the necessity to research virtual classroom. The second part defines and classifies the virtual classroom. It also describes the evolvement of virtual classroom. In the third part, we discuss the theoretical foundation of the virtual classroom and elements of building learning environments. Then we design the systematic functions of virtual classroom from three angles including teacher, student and administrator. In the same part, we also draws its function framework, and describes the process that teacher and student use the system. In the end, we summarize the model of designing and developing virtual classroom system. The fourth part of the thesis introduces the technique about developing some parts of the virtual classroom and its use.The characteristic of the work includes three parts: It defines the virtual classroom with the scientific method. It Regards traditional classroom as the prototype and designs the function structure of the virtual classroom based on the classroom teaching, making it a teaching platform that can implement all kinds of web-based courses. It develops the virtual classroom with the idea of low cost, low degree of difficulty and high efficiency. The work offers references and experiences for developing and popularizing various web-based platform.
