A case study in specifying a formative index for the analysis of an e-learning application usability
Journal Title: Romanian Journal of Human - Computer Interaction - Year 2011, Vol 4, Issue 1
Abstract
Up to now few approaches to usability evaluation exist that are using structural models to analyze the causal relations between various factors influencing the quality of use and / or the intention to use. Also, few measurement models exist that are including composite constructs targeting several dimensions. Adequate specification of measurement models according to the nature of construct and direction of causal relations between a construct and its measures is an important research topic in recent years. In this paper a synthesis of recent advances in formative models specification and validation methodology is presented. The methodology was applied to develop a structural model having as focal variable a composite construct measured with formative indicators. The purpose of this study is to get more insights into specific usability issues and to analyze the relationship between usability and the perceived enjoyment.
