Quality models of online learning community systems: Exploration, evaluation and exploitation

The main goal of this chapter is fourfold: to review key theoretical models under-pinning the design of online learning community systems (OLCSs); to identify and evaluate quality models for OLCSs; to better understand the feedback loop between evaluation of OLCSs and their redesign; and to develop a generic framework for user interface quality models for OLCSs. Specifically, we have reviewed a set of software quality standards, quality models, and literature on human-centered design, usability, information technology quality assurance, accessibility, security, and trust. Several empirical case studies are described to illustrate our arguments and views. We have developed the generic framework that comprises four levels-factors, criteria, guidelines, and metrics.
