Author(s):

Journal: Journal of Southwest University for Nationalities(Natrual Science Edition)

Keyword:  MOOC知识可视化视觉表征知识建模分析框架;
Abstract: 针对MOOC学习缺乏深度的现象,提出了面向MOOC的知识可视化视觉表征与建模设计.剖析了MOOC学习缺乏深度的主要问题和信息加工的内在要求,厘清了知识可视化、表征、建模等基本概念;在借鉴了视觉传播取向和信息论视角的知识表征基础上,提出了面向MOOC的视觉表征框架;在此框架下,分别从语义、语用、语法信息三要素着手,阐释了具体的分析方法.在语义上,基于Bloom教学目标分类法确定知识的类型、提取过程和表征方法;在语用上,陈述了信息有效传达的基本原则;在语法上,介绍了具体的结构模型和可视化方法.实践证明,MOOC的学习者在表征框架下,能增强认知联结、拓展广度、增加深度,从而满足深度学习的诉求.
