現今由於網路使用人口快速增加，以及多媒體應用在網路上技術的日瑧成熟，使得網際網路人口不斷迅速的成長，網路時代已經來臨。網路對傳統生活造成諸多變革，在傳統的教學環境上亦有重大的改變。利用網路來建立數位學習環境，提供使用者更多、更方便且更容易汲取的學習資源，它運用了生動的多媒體呈現方式來提高學習興趣、增加學習效果，亦可藉由聲音、文字、圖片和影像等媒介，將一端學習者的經驗、知識提供給網路另一端的學習者分享，進而達到互動式的學習效果。
本論文提出一個建構在Web環境以元件為基礎的即時互動合作學習平台，目的在以元件軟體開發的方式來建構系統，這樣可以使系統更容易擴充與維護。此理念可降低開發網路教學平台的成本並能分享應用。

Internet has grown rapidly all the time due to unfailing increase of user population and the gradually matured techniques in multimedia application on the network. Internet has brought a lot of transformations to our life, including the changes of traditional learning and teaching. The appearance of digitized learning environment provides users large, convenient, and easily absorbed learning resouces. It can increase the interest and improve the effect of the learning by making use of vivid display with multimedia. The user can share their experiences and knowledges each other on Internet via text, image, audio and video transmitting, achieving a interactive learning.
In this paper, we propose a web-environment component-based e-learning platform supporting real-time and interactive learning activities for users. We employ the method of component-based software development to construct the system, making the system expandable flexibly and maintainable easily. Besides, we adopt the principle of independency and scalability to design the system. Such an idea can reduce the cost of developing the system and can make the application sharable on the Internet.
