Investigation into Object Oriented Architecture for Extensible Learner-Adaptive Environment

We propose a flexible architecture that is capable of function extension for a learner-adaptive self-learning environment. We have introduced the concept of a “courseware object”, which is a program module that is used to implement various educational functionalities, and, thus, the proposed architecture allows incremental function extensions while maintaining the existing functionalities. To implement the functions of SCORM 2004, a representative learner-adaptive system specification using hierarchical content structure, we have investigated the basic behavior and interactions of courseware objects.
