Development of Augmented Reality application for learning the concept of molecular geometry

Abstract

This research aimed to develop and measure the usability of the Augmented Reality App used for learning Chemistry, focusing on the concept of molecular geometry. AGILE model of development was employed to step by step development, starting from the analysis of the curriculum and need assessment, followed by design, development, deployment and evaluation. Some computer software such as Vuforia (database), unity (App generator) and blender (3D object maker) used at the development stage of the app. 17 students took part in the testing phase of the app. The students evaluated the ease of use of the app using the System Usability Scale (SUS). The SUS score of the app was 92,7, which means the app is easy to use, and most of them would recommend the app for other students. The result indicated that the app is user-friendly, light, and useful to learn the concept of molecular geometry.
