摘　　要：E-learning极大的丰富了学习方式和学习资源,同时也使得学习者和教师面临超认知负荷等问题。要从根本上提升人的认知能力几乎是不可能的,只有用现代技术手段分担一部分人的认知负荷,而信息可视化无疑是一种很好的解决办法。通过Prefuse可以非常方便地实现E-learning中的学习分组情况、学习内容和学习过程中所结成的社会关系的可视化,这在缓解师生认知负荷、方便教学评价和规范E-learning平台的设计与开发等方面都是非常有意义的。E-learning has certainly enriched the learning styles and learning resources, but learners and teachers also face such problems as super cognitive load as well. Meanwhile, it is almost impossible to improve human＇s cognitive ability fundamentally. The only way is to share parts of the cognitive load by the use of modern technological means, and information visualization is undoubtedly a good solution. Prefuse realizes the visualization of learning grouping, learning content and social relations formed in the learning process in e-learning, which is very significant in easing cognitive load, promoting instructional evaluation and the standard in the design and development of e-learning platform.
