Design and Implementation of Object-oriented Architecture for Extensible Learner-adaptive Self-learning System

Abstract

This paper describes a design and implementation of object-oriented architecture for a learner-adaptive self-learning environment. The design goal of this architecture is to provide a flexible self-learning environment that ensures both function extensibility and content reusability. A prototype system was designed and implemented to investigate the feasibility of the proposed architecture and to identify the core behavior and interaction schema of courseware objects. Successful implementation of fully functional SCORM 2004 execution system into the proposed architecture indicates its practical capability as a common platform for various learner-adaptive functionalities.
