A Patterns-Based Approach for Modeling Instructional Design and TEL Systems

The core idea of patterns and pattern languages is the encapsulation, modeling and delivery of expert's knowledge and best practices to novices in a discipline. The use of such an approach is critical for modeling Instructional Design (ID) as it forms the basis for design of TEL systems (for e.g., eLearning Systems). While there is extensive work on patterns for ID from Pedagogy Patterns Project, E-LEN and so on, the focus has been on patterns at lower level of granularity rather than an approach that integrates patterns from ID and TEL perspectives. In addition, most of the researchers have focused either on domain patterns (ID) or TEL patterns, and not both. In this context, this paper presents a patterns-based approach to design of TEL systems based on ID. The crux of this approach is to model a solution in ID using patterns and integrate it with a solution in TEL. To this end, we present an approach that integrates Pattern-Oriented Instructional Design (POID) and Software Architecture for TEL Systems based on fundamental principles in software engineering (SE). We then illustrate our approach and ID patterns through adult literacy case study.
