摘要
为了实现虚拟课堂、打破时空限制,解决彼此相距千里的教师和学生之间的授课问题,满足远程在线"教与学"的需要,实现在线交互式远程视频教学。在此阐述了基于Flash的多语言可定制EPL(Eclipse Public License)开源视频会议Openmeetings平台交互式远程视频教学系统的设计思想、系统结构以及实现技术;该系统充分利用有线和无线网络平台,提供了灵活、开放、不受时间和地域限制的辅助教学形式,完善了辅助教学手段,丰富立体化教学模式。实验部分主要对系统在不同网络环境下进行了测试分析,并根据数据分析优化系统,实验证明其优化策略是行之有效的。
In order to achieve virtual classroom, break the constraints of time and distance, solve the teaching problem that teachers are far from away to students, meet the needs of the remote online teaching and learning, and implement online in-teractive remote video teaching, the design idea, system architecture and implementation techniques of the interactive remote video teaching system with customizable Flash-based muhilingual EPL （eclipse public license） open source video meeting Open-meetings platform are elaborated. The system takes full advantage of wired and wireless network platforms to provide a flexible assisted instruction in the forms of open, independent of time and geographical constraint, improves secondary teaching me-thods, and enrich three-dimensional teaching model. The system was tested in different network environments, and was opti-mized according to the data analysis. The experiment proves that the optimization strategy is effective.
