Research on CAI Systems Development Environment using Distributed Object Technology for IT Education

该方法论以信息工程和面向对象技术为基础，用于支持课件开发的导航、辅助教学组件的课程设计和辅助教学系统的资源管理。基于知识库的方法是支持计算机辅助教学系统开发和重用应用程序框架和组件等计算机辅助教学系统资源的关键。通过元模型/模型/对象库等存储库的结构，并使用面向对象的建模，构建它以供系统分析人员和主题专家重用。系统分析人员可以通过重用元模型和目标系统的模型来构建新的模型。主题专家可以通过重复使用模型和对象库来开发他们的课件。由于互联网在全球范围内的使用，学习环境也正在改变，以融入互联网的使用。在大学、民营企业等各类组织中，主题专家正在开发各种类型的课件；每个站点都可以联网，用来制作各种课件。采用CORBA体系结构，开发了分布式计算机辅助教学系统开发环境。

The methodology, which is based on information engineering and object-oriented technology, is used to support navigation for courseware development, designing the curriculum of CAI components, and CAI systems resources management. A repository-based approach is key to support of CAI systems development and reuse of CAI systems resources such as application frameworks and components. By the structure of the repository such as meta-model / model / object base and by use of object-oriented modeling, it is constructed for reuse by systems analysts and subject matter experts. Systems analysts can build new models by reusing meta-model and models for their target system. Subject matter experts can develop their courseware by reusing models and object bases for their CAI systems.Since the Internet is used worldwide, learning environment is also changing to incorporate use of the Internet. In various types of organizations, such as universities and private enterprises, subject matter experts are developing various types of courseware; each site can be connected to the network and used to make a variety of courseware. By using CORBA architecture, we developed the distributed CAI systems development environment.
