知识可视化视觉表征的形式分析

The Form Analysis of Visual representation in Knowledge Visualization

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。知识可视化的视觉表征并非孤立的单位，而是符号的系统。根据视觉形式分为表层形式和深层形式，可以分别阐释知识可视化视觉表征的形式特征。知识可视化视觉表征的表层形式为色彩、线条和大小等材料因素，深层形式为线性结构、循环结构、圆形结构和网状结构和隐喻形式等空间关系。知识可视化视觉表征的形式设计中，需要构建视觉表征的结构关系，展现内容性元素；应用线条、色彩和大小等材料因素，发挥修饰性作用；文字符号与视觉形式结合，明晰所指代的内容。

In education technology， knowledge visualization refers to visual representation form， and corresponds to the graphic tool. Visual representation is not an isolated unit， but the symbol systems. Visual form is divided into surface form and deep form， and then we separately explain the visual representation of knowledge visualization in the visual form; According to the features of visual form， the surface form of visual representation includes colors， lines and other physical materials， deep form includes linear structure， loop structure， circular structure and the mesh structure， metaphorical form and other spatial relations. In the form design of visual representation in knowledge visualization， it is needed to construct the structure of visual representation， showing the content element; use the material factors such as lines， color and size， reflecting the modified effect; sign language and visual forms， making the content clear.
