Evaluating the usability of FTMSK online test system using shackel\s model

One of the most important characteristic of an online learning system is its ability to access the  ease of use of the system. Nowadays, many types of application for e­ learning have been developed.  However, most of the software developers only focus on developing the system but not concern about  the usability of the system. In reality, the usability of the system is an important aspect of  system development. Poor usability will effects the utility of the system and will wasted the  user's time, causes worry and frustration and discourages further to use the system. Therefore,  usability testing has been considered as a potential method to evaluate a system. Based on  Shackle's Model of usability, the questionnaire is designed to evaluate the FTMSK Online Test  System. The questionnaire is based on the four usability factors such as effectiveness,  learnability, flexibility and attitude to determine students' and lecturers'  view  on  the online   test system. The usability  testing  also has been conducted with the lecturers as a test subject.  The result of this study showed that the overall level of the usability for four construct  (effectiveness, learnability, flexibility and attitude) in student's point of view are in the  acceptable·level (mean=3.9279). While, from the lecturer's point of view, the overall level of the  usability are also in the acceptable level (mean=3.833 l).  From the research, we also found that  both students and lecturers acceptance toward the online test system is most highly in positive  level. The gender and online test experience do not influence lecturers' and students' acceptance.  This is because most of them are exposed to the information and communication technology. In  conclusion, the usability testing method has an ability to determine the level of user's acceptance on using the online test system
