Research on Advanced Teaching Method in Distance Education by Communication Agent

配置了能够以PowerPoint幻灯片、视频图像、手写文字、静止图像等多种媒体进行授课的多媒体远程授课系统，通过试验确认了其效率。开发了能够通过图标控制授课时的设备操作的辅助软件。它的效率导致了对声音/语音控制系统的进一步研究和开发。利用Web技术，开发了远程授课的教师与学生之间的通信代理，构建了基于H. 323的IP网络上的同步/异步集成系统，实现了教师与学生之间以MPEG 1等效图像的交互。该系统可以与WBT协同工作，并验证了系统的有效性，开发出了一套面向未来的电子教科书模型。它根据学习者的要求编辑数据，并检索他或她需要的教科书。它还使学习者能够向讲师提问，并通过启动视频会议系统访问FAQ数据库和解决问题。

A multimedia distance lecture system, which can express a lecture in a variety of medium such as PowerPoint slide, video images, handwriting letters, still pictures and the like, has been configured, and we are assured of its efficiency through the test.We have developed a supporting software with which equipment operation during a lecture can be controlled by icons. Its efficiency has led to a further research and development of a system controlled by sound/voices. We are now applying for its patent.A communication agent has been developed with which the lecturer can get feedback from the students in distance sites during a lecture with Web technology.A synchronous/asynchronous integrated system which realizes the interaction between the lecturer and the student with a MPEG1-equivalent image on H.323-based IP network has been configured. It can co-operate with WBT, and we have confirmed the efficiency of the system.We have developed a model electronic textbook for the future. It edits the data at the learner's request and retrieves what textbook he or she needs. It also enables the learner to ask the lecturer questions and to get access to FAQ database and solve problems by booting up a video conference system.
