多媒体教学演示系统制作平台的设计与实现

DESIGN AND REALIZATION OF THE PRODUCTION PLATFORM FOR MULTIMEDIA INSTRUCTION DEMONSTRATION SYSTEM

从教学应用角度探讨了演示系统制作平台的模式．该平台（ＤＭａｋｅｒ）的设计采用并扩充了面向对象的软件设计方法．对象中既包含了数据的属性和行为，还增加了节目安排、事件响应等特性，并且为用户提供了一个可扩充的控制库．ＤＭａｋｅｒ具有一个可视化的集成开发环境，用户完全不须使用程序设计语言，开发出的ＣＡＩ教学演示系统既可多元联动，又可独立动作；既可按节目编排自动播放，又可响应用户输入、灵活跳转．ＤＭａｋｅｒ是一个适合于一般教育工作者使用的、开发教学演示系统的有效工具．

CAI instruction demonstration system is designed to teach visually, describe the variant process of problem, analyze thoroughly the knowledge point. The production platform for multimedia instruction demonstration system (DMaker) is designed for this purpose. This production platform is designed with object oriented method, the object including not only the pro_ perty and action of data but also some new feature, such as action arrangement and event processing, and provides the user a extensible database of control. The DMaker provides a visualized integrated developing environment. The user can develop without programming a CAI instruction demonstration system which is able to devise multiple cooperative actions or a single action, to automatically play the arranged actions, and to response the user input and jump accordingly. In conclusion,damper is a efficient tool to develop instruction demonstration system for teachers. This paper also discuss a pattern of the production platform for multimedia instruction demonstration system, and outline the design idea and implementation method from the aspect of application in instruction.
