移动学习系统理论模型研究

Research on Theory Model of M-learning

首先对活动学习理论、情境学习理论、分布式认知理论、会话学习理论等移动学习主要理论依据进行了分析及对比，进而基于Sharpies的\＂分析移动学习的活动理论模型\＂、Salomon的\＂个体认知与分布式认知的交互模型\＂和Laurillard的\＂‘技术支持学习的会话模型框架＂提出了用于移动学习系统分析的会话——活动——分布式CAD理论模型，对结构、边及顶点的意义以及作用进行了阐释，并结合移动学习典型案例分析了CAD模型的具体应用。

Firstly contrast the theory of activity learning， context learning， distributed cognition， conversation learning and so on. Based on the ＂Analysis mobile learning activity learning theory＂ of Sharpies， ＂interaction model of Individual cognitive and distributed cognitive＂ from Salomon and ＂Technical support learning sessions model framework＂ of Laurillard， the paper comes up with CAD (Conversational， Activity and Distributional) which is useful for analysis on m-learning systems. This paper also expounds the structure， significance of edge and vertex of CAD， and analyzes application of CAD model on two typical cases of m-Iearning.
