Usability Testing of DataPintar Mobile Application for Learning Data Measurements among Secondary School Students

The evaluation of usability in software applications is a crucial aspect of ensuring that the end product is intuitive, user-friendly, and effectively meets users’ goals. Leveraging the ISO 9241-11 framework, this study evaluates the usability of an iOS mobile application, DataPintar, developed specifically to provide interactive learning experiences for data measurement concepts within the Fundamental of Computer Science subject. Focusing on three key components, which are effectiveness, efficiency, and satisfaction, this study was conducted among 30 secondary school students enrolled in The Fundamental of Computer Science course. A total of 14 tasks were administered to the participants, and the results indicated high usability, with a 100% task completion rate and an overall satisfaction score of 87.85%. DataPintar was found to be a promising mobile application for enhancing learning outcomes, as it was easy to use and featured simple tasks. However, the findings suggested that minor adjustments should be made to improve the user experience, such as modifying the arrangement of buttons to ensure information is retrieved with more ease and improving the responsiveness of certain sliders in the mobile application. The study contributes to the advancement of usability evaluation research, focusing on educational mobile applications. This study highlights the importance of incorporating usability evaluations to ensure a user-centred design and rigorous usability testing, ultimately improving learning tools and fostering engagement in secondary education.
