An Asynchronous Serial Communication Learning Media: Usability Evaluation

Abstract

The availability of a good acceptable learning media is a vital part of the learning process. This paper presents a usability evaluation of the asynchronous serial communication module, which can exhibit the level of acceptance of Data Communication's students. The survey was performed based on ten simple statements of the System Usability Scale (SUS) questionnaire. The research's findings have been analyzed in three different approaches, i.e., visual "five-pointed star" shape assessment, Bangor et al. model verification, and curved grading scale justification. The analysis showed that the serial communication module is in the acceptable category.
