Development of Augmented Reality Based Geometry Learning Media Oriented to Balinese Architecture to Improve Ability Student Mathematics Spatial

Abstract

Media Augmented Reality is very relevant for student learning based on information and communication technology. However, learning using AR has not been widely used, especially when learning mathematics. This study aims to determine the quality of augmented reality media oriented towards Balinese architecture and the implementation characteristics when using the media in learning. AR media packaged in an android mobile application is included with a marker to scan 3D objects to improve students' mathematical spatial abilities in geometry learning. This research is design research using the Plomp model. The research subjects were students of class X SMA. So, the data collection methods of this research are observation, interviews, tests, and questionnaires. The validity test results show that the media is very valid, scoring 3.68. The practicality test showed that the development included AR media in the efficient category with a score of 3.5. Finally, the effectiveness test indicates that the AR media developed effectively increases spatial ability with an average score of 85, reaching the completeness criteria. This result shows that AR media is oriented to Balinese architecture with valid, practical, and effective quality. One of the characteristics of the media developed is that AR media can display 3D objects so that students are given space to explore, imagine and conclude the material obtained. Then, the characteristics of using the media, namely AR media, can be used as an alternative to spatial geometry media in overcoming the limitations of presenting material in schools.
