Design Patterns in Adaptive Web-based Educational Systems: an Overview

Adaptive Web-based Educational Systems represent an emerging technology that provides a unique advantage over traditional Web-based Educational Systems; that is the ability to adapt to the user's needs, goals, preferences etc. Adaptive Web-based Educational Systems are increasingly becoming part of the mainstream education, yet there does not exist a disciplined way of designing them most of the development is ad-hoc. This paper aims to fill this void, which is the absence of disciplined design, by recording the expertise of existing Adaptive Web-based Educational Systems in the form of design patterns. We present a categorization of the patterns according to an established paradigm in Adaptive Hypermedia, we examine the patterns in one of these categories and provide an exemplary pattern.
