Development of Android-based application: Innovation for the calculus for physics course

In providing an optimum learning process, students should be given more space to develop their understanding by integrating their knowledge into daily problems. Students should not only learn through lectures in class but also resources available anywhere and anytime. In previous lectures, physics students were still unable to interpret physics problems into mathematical representations (Calculus subject) causing the obtained scores of midterm and final exam not optimum. Thus, through this work, students are expected to understand Calculus principles and able to use the principles towards physics problems. One method to improve the learning process is by using learning media applications. The research design of the “Physics 101 - Calculus 1” application is Research and Development (R&D). The development stages including the defining stage (student analysis, needs analysis, concept analysis), the design stage (product design), and the development stage (product validation, revision, testing, product revisions (if any), and final products. The results of the product quality research are expressed by the Likert scale. This application was created using the Android Studio software that can be installed and used optimally on mobile devices with the Android operating system at the minimum version of 5.0 and the minimum RAM of 1 GB. The size of the application is relatively small around 2.126 MB. “Physics 101 - Calculus 1” has been validated by media experts. The average percentage score was 92.11% which shows that the media is valid. Besides, the application had also been tested on 25 students and its average percentage score was 91.56% which shows that the product is feasible. Thus, the Physics 101 - Calculus 1 application is concluded to be valid and suitable for use by academics.
