An Enhanced Learning Technology System Architecture for Web-Based Instructional Design

Instructional design (ID) models are proven prescriptive techniques for qualitative lessons that could guarantee learning. Existing Learning Management Systems (LMS) miss-out the roles of this important quality control mechanism by providing a mere plane and passive platform for content authoring, thus becomes vulnerable for poor instructional design. This paper demonstrates an effort to ameliorate this limitation by extending the IEEE Learning Technology System Architecture (LTSA) with ID design processes. The Use Case diagram, Activities diagram and Entity Relation diagram for the extended LTSA are presented. The extended architecture was implemented on Moodle open sourced LMS which was extended and hosted live. Students’ impressions on the functionalities and operational effects of the platform were collated using online survey. The academic effects of the platform on the students’ performance were determined using the class mean. The value obtained was compared with that of the control group in the same session and those from the previous sessions. Consequently, this work demonstrates the feasibility of integrating ID models in E-learning. It also justifies its effects on the quality of learning.
