Abstract: Through researching drawing way of concept mapping in modern education and group collaborative learning，simulating the pen-paper interactive mode of user’s reality environment，authors develop a tool which is pen-based and supports group to edit the concept mapping collaboratively.The electronic pen which replaces the mouse and keyboard is used real-time drawing the concept mapping in the tool.The tool supplies multimedia communication information which is composed of literal，audio and video，enhancing the ability of collaborative awareness of system，group user can collaboratively draw concept mapping through convenient，natural and effective mode.

Key words: concept mapping, pen interaction, collaborative awareness

摘要： 通过对实际教学中概念图和群体协同学习进行研究，模拟人们使用纸笔交互方式的习惯，用电子笔取代了鼠标键盘作为输入设备，实现了一个支持群体绘制的笔式概念图工具。使用该工具，多个用户可以在网络上协作绘制概念图，在绘制过程中，所有用户都能实时地感知整个概念图的绘制过程。为了方便用户讨论绘制过程中所遇到的问题，该工具提供了文字、音频和视频三种交流方式，用户可以选择任意一种或多种方式进行实时交流。
