混合式协作学习中知识建构的三循环模型研究

Three-cycle Mode of Knowledge Building in Blended Collaborative Learning

在混合式协作学习(Blended Collaborative Learning，简称BCL)的探讨中，为了有效促进和科学分析学 生的知识建构，该文经过多年的实证研究，对Stahl的知识建构模型进行了改造，提出与应用了BCL知识建构的三 循环模型。该模型含个体知识建构、协同知识建构、基于点评讲解的高层次认知三个循环。同时，为了探寻BCL 中知识建构的特征与优化策略，设计了BCL中交互制品的内容分析编码体系与质量评价量规，并利用该模型和编 码体系对BCL社区交互进行了综合分析。

For effectively promoting and scientifically analyzing students’ knowledge building in Blended Collaborative Learning (BCL)， The author has worked on empirical research for many years. The paper upgrades Stahl’s model of knowledge building， presents and applies three-cycle model of knowledge building in BCL. This model contains “individual knowledge building” cycle， “collaborative knowledge building (CKB)” cycle， and “higher cognition based on comments and interpretation” cycle. Furthermore， for pursuing the feature and optimization strategies of knowledge building in BCL， The paper develops encoding system of content analysis and the rubric of quality evaluation of interactive artifacts. Using the model system and encoding system， The author have a comprehensive study about community interaction in BCL.
