中文摘要：

协作学习活动结构是对协作学习过程的一种设计、规划和描述。教师通过设计协作学习活动结构对协作学习过程实现隐性控制,促成协作学习有效发生。在阐述协作学习活动结构设计的流程和原则基础之上,系统建构了协作学习活动结构设计的任务分析、时序排列、角色定义和资源分配4种策略,并分析了协作学习活动结构化的局限。

英文摘要：

The structure of collaborative learning activity can design, plan and describe collaborative learning process. Teach- ers implicitly control collaborative learning process to improve learning outcome by means of designing the structure of collaborative learning activity. After discussing the process and principle of the design of the structure of collaborative learning activity, the paper puts forward four strategies： task analysis, sequencing, role scripting and resource allocation, and analyzes the weakness of the structure of collaborative learning activity.
