Abstract: “In this paper, we propose the Rasch analysis for studying an existing measurement model towards a design. The user satisfaction measurement model (e-Learner Satisfaction (ELS) and Website User Satisfaction (WUS)) was used to show how to understand users’ response patterns. A twenty four item questionnaire was adapted based on the user satisfaction measurement model and administered to 86 students. The user satisfaction responses towards the design of the On-line Discussion Site (ODS) in Universiti Teknologi MARA (UiTM) e-learning portal were investigated. Step by step guidance is provided on how data was analyzed in understanding users responses towards the ODS design using the Rasch analysis. The findings from Rasch analysis will reveal the likelihood of user satisfaction with the ODS design. Thus the Rasch analysis was able to provide the most and least agreed items in a measurement model. Thereby system designers can easily identify items that need to be further improved in a design”
