Abstract
The visualization of objects of an abstract nature has always been a challenge for chemistry learners. Thus, augmented reality (AR) and virtual reality (VR) have been heavily invested in as immersive learning methods for these concepts. This study targets the segment of the chemistry curriculum involving the chemical elements of the periodic table. For this purpose, we developed the AR educational tool called MicroWorld. This Arabic educational AR app was developed in unity with Vuforia SDK. Using MicroWorld, students can visualize chemical elements microstructures in 3D, see 3D models of the elements in their substantial forms, and combine two chemical elements to see how certain chemical compounds can be formed. In this work, MicroWorld’s usability was evaluated by junior high school students and chemistry teachers using the Arabic system usability scale (A-SUS). The A-SUS average score was 71.5 for junior high school students, while the scale for teachers reached 76. This research aims to design, develop, and evaluate the AR app, MicroWorld. This app was built and evaluated through the lens of the design science research paradigm.

We argue that the MicroWorld app is a promising tool that can facilitate the learning process for both learners and teachers
The evaluation in design science research can be done from two perspectives: a sociotechnical perspective and/or a technical perspective
Summary
Faculty of Computing and Information Technology, King Abdulaziz University, Jeddah 21589, Saudi Arabia; Citation: Alrige, M.; Bitar, H.; Abstract: The visualization of objects of an abstract nature has always been a challenge for chemistry learners. This study targets the segment of the chemistry curriculum involving the chemical elements of the periodic table For this purpose, we developed the AR educational tool called MicroWorld. Junior high school students still consider chemistry one of the most difficult courses to grasp and learn its abstract concepts To fully comprehend these concepts, they must integrate information from the macroscopic, microscopic, and symbolic domains of the discipline. Abstract concepts, such as atoms or special representation by the element, are most forgettable to junior high school students. One systematic review found that the use of AR in Science, Technology, Engineering, and Mathematics (STEM) education can foster students’ conceptual understanding [5]
