摘要： 试图利用多媒体技术中的可视化方法．用于建立数据结构课程中算法的可视化动态执行模型，尽管目前这种换型只能做到部分自动生成，但这种折衷的实现方案用于该课程的CAI制作还是取得了有益的效果。该课件内容的组织和呈现采用了面向对象的建模方式，使得整个软件结构清晰简单。其中内容以对象的属性表示．呈现方式则按对象的操作组织起来．既可以用文本方式．又可以用可视化的动态模型表示，最后以一个统一的界面提交给用户。

Abstract: This article describes an effort to build a computer-aided instruction system for data structure course. The system is based on thevisualized dynamic execution model specially established for the algorithms in the course via utilizing the visualizahon method of mulhmediatechniques. Although the generation of the model can only be automated partially now, this compromised hoplementation way workssatisfactorily in our project. The overall system is structured into several types of objects in which the static and dynamic behavior knowledgeof the courseware is organised as object's attributes, with the presentation of these knowledge colltent as obect's methods. A teaching GUI isimplemented on these object models, giving both student and teacher an unifom interface to inihate various teaching or learning activihes.
