本研究針對群體電腦輔助教學環境之建置，提出一個以群體軟體發展架構為基礎的系統開發方法論，並運用於群體拼圖軟體之開發過程中，以驗證其可行性。本研究的主要貢獻為：(1) 將群體軟體的觀念引入電腦輔助教學的領域中，並主張「群體電腦輔助教學軟體」的研究開發；(2) 提出一個能夠有效指導群體電腦輔助教學軟體發展的群體軟體功能分類方法；(3) 提出一個整合各類群體電腦輔助教學軟體發展的三層式系統架構，使得共用模組的建立更為容易實現。

This paper proposes a systematic approach, based on a groupware developing framework, to construct Group CAl environment. The approach is then applied to the development of a Group Puzzle to verify its feasibility. The primary contributions of this research are threefold. First, we introduce groupware concepts into the field of CAl, and advocate the development of Group CAl software. Second, a groupware functional classification method is raised that can direct the development of Group CAl software effectively. Finally, this paper proposes a three-layer system architecture for intergrating different kinds of Group CAl software. Using this architecture, the concept of sharing modules is much easier to implement.
