采用模型-视图-控制器的设计模式，分析了计算机支持的协作学习系统的四种体系结构，并从用户活动与教育用途的耦合性、网络负载与实现的简易性等角度进行了比较。这些体系结构以Belvedere的发展历史为例进行了说明，Belvedere是一个在问题解决过程中协作构建知识表示的环境。支持模型级耦合的混合体系结构可以提供最佳的设计折衷。
Four architectures for computer supported collaborative learning systems are analyzed using the model-view-controller design pattern and compared from the standpoints of coupling between activities of the users and suitability for educational use, as well as network load and ease of implementation. The architectures are illustrated with examples from the developmental history of Belvedere, an environment for collaborative construction of knowledge representations during problem solving. A hybrid architecture that supports model-level coupling is shown to provide the best design tradeoffs.
