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.
