CORAL*:一個多俟服器的遠距合作學習系統

Abstract

在此篇論文中,我們將介紹一個多俟服器架構的CORAL係統. CORAL系統 是在一個計劃中所發展出來的遠距合作學習系統,為一個單俟服器的架構. 我們將此系統擴展成多俟服器的架構,並使之成為一個更緊密結合的合作 學習系統.我們發展了多俟服器的管理程序及使用者的管理和擴充原來的 單俟服器溝通管道成為多俟服器的溝通管道.此外我們增加了四個功能:導 覽系統,郵件系統,語音系統及學習查尋係統.我們希望此系統能提供學生 一個良好的合作學習環境. In this thesis, we introduce a multi-server CLRAL system. CORAL, a distantant cooperative learning system, was developed with a single-server architecture originally. We expand CORAL to a multi-server architecture and make it a tightly-coupled system. WE develope multi-server and user management procedures and extend single-server communication channels to multi-server communication channels Besides, we add four features into this system:the guided navigation system, themail system, the audio system and the learning activities query system. We expect this system to provides students with a helpful cooperative learningenvironment.
