e-Learning视域中知识可视化模型比较研究

A Comparison Study on Knowledge Visualization Model in the Field of e-Learning

随着知识可视化工具应用日渐普及,学术界对于知识可视化的研究逐步深入,相关研究者提出了较为系统化的知识可视化模型。该研究基于e-Learning视域,对现有的典型知识可视化模型进行比较分析,旨在挖掘分析知识可视化的过程和方法。通过分析发现已有知识可视化模型在其构成要素和核心过程上基本一致,但在理论基础、差异性要素以及交互定位等三个方面存在一定差异。对知识可视化的交互进行深入研究,以及根据知识类型的差异采用针对性的知识可视化方法,这两点将成为后续相关研究的关注重点。本研究对于完善知识可视化基础理论,指导知识可视化实践有着重要意义。

With the widespread application of knowledge visualization tools, the research of knowledge visualization is becoming more and more deeply, and the related researchers put forward a more systematic knowledge visualization structure model. In this study, the existing typical knowledge visualization models will be compared and studied more deeply based on E-learning. The purpose of this study is to understand the process and method of visualization. It is found that the various knowledge visualization models are almost identical in their constituent elements and core processes, but there are differences in the three aspects of theoretical basis, the differences between the elements and interaction orientation. We study the interaction behavior of knowledge visualization, and adopt different knowledge visualization methods for different types of knowledge, which will become the focus of building knowledge visualization model. This study is of great significance for improving the basic theory of knowledge visualization and guiding the practice of knowledge visualization.
