【摘要】在教育技术领域，知识可视化指视觉表征形式，与此相对应的是承载知识的图解手段。随着知识可视化研究与应用的不断深入，视觉表征已经成为知识可视化研究的新要求。知识可视化视觉表征研究目前已经从知识、技术、图像等角度开展，然而缺少了观看者和制作者等因素，并且尚未剖析因素之间的深层次关系。信息论可以为知识可视化视觉表征研究提供新的视角。根据理解信息需要先形式、后内容和再效用的过程，并结合教育技术专业注重设计的特征，知识可视化视觉表征的分析框架应该包括形式分析、内容构建、意义解读和设计方法。其中，形式分析侧重于视觉表征符号结构的特点，内容构建侧重于如何赋予视觉表征知识内容，意义解读侧重于观察者解读视觉表征内容的过程，而设计方法则侧重于制作者制作视觉表征的思路。

Abstract: In educational technology, knowledge visualization refers to visual representation form, and corresponds to the graphic tool. Under knowledge visualization research and in-depth application, visual representation has become the new requirement of knowledge visualization study. Visual representation has been studied from the perspectives of knowledge, technology and images. But the lack of viewers and producers resulted in the lack of indepth analysis between factors. Information theory can provide a new perspective for visual representation. According to the information needed to understand the form, content, effectiveness, and educational technology with design features, analytical framework of visual representation should include formal analysis, content construction, meaning interpretation, and design methods. Among them, formal analysis focuses on the symbolic structure of visual representation, and content construction focuses on how to give visual representation of knowledge content. Meaning interpretation refers to the interpretation process of observers in visual representation, and design approach refers to how the producers create the visual representation.
Key words: knowledge visualization; visual representation; analytical framework; education technology |
