大规模开放课程的知识地图分析——以学习元平台为例

Knowledge Map Analysis of Massive and Open Course ——Taking Learning Cell Platform as an Example

针对当前MOOC课程学习过程中学习者所面临的内容组织结构差、学习散漫无计划、学习动机不足等问题，结合知识地图的特点，提出了构建大规模开放课程知识地图的解决思路。基于学习元平台，从学科知识语义关联与进化、基于学习活动的过程数据采集与分析以及知识地图的可视化呈现三个环节出发，构建了面向学习者和教师的知识地图。该地图具有可进化的学科知识语义关联、可视化的知识掌握状态表征、可动态自适应呈现等特点，不仅包含知识与知识之间的关系，还包含人与知识之间的交互状态，既能够用作知识导航，又能够作为形成性评估的工具。通过应用案例阐述了学习元知识地图在学科知识导航以及形成性评估方面给学习者和教师带来的帮助，试图为大规模开放课程知识地图的设计提供参考与借鉴。

To address students’ problems recently rising in MOOC such as poor organizational structure of content， undisciplined and unplanned learning process， lack of motivation etc.， considering the characteristics of knowledge map， this paper proposed to build a knowledge map of MOOC. Based on Learning Cell System， we have constructed learners and teachers’ knowledge map by three steps: semantic relation and evolution of subject knowledge， process data acquisition and analysis based on learning activities， and knowledge map visualization. This knowledge map has the characteristics of evolvable subject knowledge semantic association， visualization of the state of knowledge acquisition， and dynamically adaptive presents. It not only contains the relationship between knowledge and knowledge， but also includes the interaction between person and knowledge. Besides， it can be used as a knowledge navigation， and as a formative assessment tools. through the application cases， the paper described to use a knowledge map to help students and teachers in subject knowledge navigation and formative assessments， and provide information and reference for the future design of MOOC knowledge map.
