On Generic Communication Patterns between Courseware Objects in Extensible Learning Support System Architecture for Self- and Group Learning

Abstract

This paper discusses the communication patterns between courseware objects in Extensible Learning Environment with Courseware Object Architecture (ELECOA). ELECOA is intended to provide flexibility to enhance functions of learning environments without losing content reusability. A key concept of ELECOA is 'courseware objects' which are program modules included to implement new functions. This paper investigates communication patters between courseware objects to allow any combinations of courseware objects. The results show that four communication patterns defined for the original ELECOA-based self-learning environment can be applied to the group learning environment, implying that existing self-learning materials can be reused in the group learning environment.
