Usability evaluation of the operational interface of the NARERO learning system

This study explored and analyzed the usability of the operational interface of the NARERO learning system. The blind spots in the usage of the NARERO learning system were used to analyze user obstacles and to provide recommendations. In this study, the people, events, and objects were collected and analyzed through observation methods, literature collection methods, and user evaluation methods in order to summarize and organize the problems of the NARERO learning system. Furthermore, a Likert five-point scale was used to measure and analyze user evaluations and learning performance, and an objective experimental test was used to assess user satisfaction. Subjects in this study were all first-time users of the NARERO learning system. In the experimental process, each user was recorded for subsequent user evaluation. These records were of two male and two female first-time users. Subsequently, the two-part objective experiment was conducted, in which five experts and 40 high school users evaluated the system interface respectively. Ultimately, system functions were conducted to assist in evaluating learning performance. In order to ensure precision in the experiment, the experiment was conducted on the subjects in the same space and on the same machine. The study explored (1) evaluation of expert satisfaction toward system components and (2) evaluation of user satisfaction toward system components.
