摘　　要： 虚拟教室在远程开放式教学中已成为有效的教学媒体和日常教育管理的有力工具。然而,目前虚拟教室存在着交互差、实时性不强、点对点沟通困难、功能单一等缺点。为满足当前虚拟教室需要实时协同交互式等新需求,在研究原有虚拟教室功能和最新计算机技术基础上,提出采用HTML5、Node.js、Web RTC等技术,实现了一个集视频对话、即时通讯、白板演示等功能的虚拟教室应用平台。使用结果表明,该平台功能完整,使用方便,可以满足当前虚拟教室实际需要。 Virtual classroom has become an effective teaching media and a powerful tool for daily education management in the open e-learning education. However, there are some shortcomings in the virtual classroom, such as poor interaction, low real-time performance, difficulty in point to point communication and less function. In order to meet the needs of the virtual classroom for real-time collaboration and interaction etc., on the basis of the research of the existing virtual classroom functions and the latest computer technologies, this paper proposes to realize a virtual classroom application platform with functions of real-time video interaction, IM, white-board and so on, by using the technologies of HTML5, Node.is and WebRTC etc. The application result shows that the platform is fully functional and easy to use, and can meet the actual needs of the current virtual classroom.
