MoleculAR: An Augmented Reality Application for Understanding 3D Geometry

MoleculAR is a free, multiplatform augmented reality (AR) application that allows students to visualize and manipulate molecular structures in 3D, providing a more immersive and interactive learning experience. Using QR codes to generate 3D models of molecules, geometries, and orbitals, students can explore structures in real-time using their smartphones or tablets. Based on student survey responses, the app is effective at engaging students in both first- and second-year chemistry courses. Our goals for MoleculAR include providing a universally accessible tool for students to learn about molecular geometry and allowing for instructor adaptation and customization to make it as relevant as possible for individual courses. The skills students develop with the help of the app are highly transferable to other topics or areas, making it a valuable resource for educators in other fields. We welcome other educators to adopt the app to facilitate their teaching and improve the learning outcomes for their students.
