由於電腦網路科技的精進與全球資訊網的流行，現代的網路教學環境不僅突破傳統教室教學環境時空的障礙，同時也提供多元化的教學呈現方式。然而，目前大部分的群體合作學習環境大多依然著重於如何設計一個引人注目的人機介面，完全忽略了如何設計ㄧ套整體的合作機制，來有效的支援一個在虛擬環境中共同工作的群體。本研究根據組織行為學、網路教學和電腦輔助合作系統等理論，將傳統的教室教學活動移轉到Web上；不但克服了時空的限制，並架構出網路教學環境所需的群體合作機制的特性。這些特性包括了物件的關連性、物件自動通知和改變管理、物件間的工作代理、物件間的磋商談判、觸發事件的監視、物件的過程追蹤和物件的限制管理。本研究根據所提的合作機制特性，以Java為開發語言，發展並實作了一個群體合作競賽應用程式雛形，證實整合物件導向技術、Java物件導向語言、網際網路技術和所提合作機制於網路教學的可行性。本研究的成果將對未來有志於設計一個動態的且互動的Web群體合作教學軟體的研究者，提供一個重要的參考價值。

　　　　　Because of the advanced technology of computer and network systems and the popularity of the Internet, not only the web-based teaching environment has broken the time and space barrier of the traditional in-class teaching system but also has provided a rich environment for presenting versatile, interactive teaching material. Currently, most collaborative learning environments mainly focus on how to present an attractive human-machine interface, and totally ignore the issues of how to design a set of collaborative mechanisms to effectively support a group of people working together in a virtual world. This study has analyzed the theory of organization, the methodology of Internet-based teaching and learning, and the technology of computer supported cooperative work. Then, a set of collaborative mechanisms have been introduced and graphically presented. The applicability of integrating collaborative mechanisms, Java, and Internet technology on the World Wide Web has also been investigated, and found to be feasible through the implementation of a collaborative group competition prototyping system. The result of this research will be useful as guidelines for future systems featuring dynamic, interactive, and collaborative teaching and learning.
