The feasibility of an Android-based pocketbook as mathematics learning media in senior high school

Abstract

Learning media is a tool to deliver the materials to students during teaching and learning process and used as a source of learning like textbooks. However, textbooks are sometimes considered less practical and boring. The innovation that follows the technology advancement is undeniably needed. Nowadays, students are very creative using smartphones. The students' creativity should be supported for better learning. One of the efforts is making use of a smartphone or mobile technology as a learning media. This study aims to develop an Android-based learning media called Trigonometry app and evaluate the validity and practicality of the learning media. This learning media is expected to help students learn mathematics. This study used the ADDIE development model. The learning media was validated by six experts and tested by 95 respondents. The results show that the learning media met the valid criteria with kappa value ranged from 0.562 to 0.843. The learning media was also considered practical based on the responses from the users. 86.32% of the users stated that the learning media was excellent and best imaginable. Therefore, the learning media is declared valid and practical to use in the classroom. It is necessary to conduct further research to investigate the use of the media in the classroom and its impact on students' learning and teaching practices.
