面向问题解决的在线协作知识建构

Problem-solving Oriented Online Collaborative Knowledge Building

"在线无协作、协作无建构和建构低水平"是深度在线协作学习面临的现实问题,其原因主要在于在线协作知识建构水平的连续统组织探究缺失。为解决这一问题,建构了"面向问题解决的在线协作知识建构"模型,模型以问题解决为视角,以"场"的知识创造隐喻为基础表征了在线协作问题解决的知识建构动态系统结构,以自组织理论实现了问题解决过程的连续统管理。模型包括问题解决系统、学习环境系统、协作学习活动系统、问题解决活动组织系统、教与学活动系统。在基于设计研究方法的指导下,预设模型通过三轮迭代实验实现了逐步完善。研究结果表明,该模型对于提高在线协作知识建构水平,特别是高级知识建构水平具有明显的促进作用。

Online learning without cooperation, cooperation without knowledge building and shallow construction are realistic problems of online collaborative learning. The reason mainly lies in the lack of continuous organization of online collaborative knowledge construction. In order to solve this problem, a problem-solving oriented online collaborative knowledge building model is constructed. Based on the knowledge creation metaphor of ＂field＂, this model represents the dynamic system structure of knowledge construction of online collaborative problem solving and realizes the continuum management during problem solving through self-organization theory. The model consists of five basic systems, namely problem-solving system, learning environment system, collaborative learning system, problem-solving organization system, teaching and learning system. Under the guidance of design-based research method, this model has been gradually improved through three rounds of iterative experiments. The results show that the model can significantly improve the level of online collaborative knowledge construction, especially the high-level knowledge building.
