Mental visualization and manipulation of three-dimensional structural objects often present a major challenge that students face when learning new concepts in introductory material science courses. Students must possess a profound and intuitive understanding of such abstract 3D concepts to fully understand the fundamental interplay between structure and properties of different materials. In a traditional classroom setting, educators rely heavily on conventional methods such as sketching, or video animations etc., to help students visualize such complex objects. While some students may have the innate nature to comfortably visualize 3D imageries, others may need several hours of practicing.
Mixed reality tools provide capabilities to view 3D objects as holograms as an overlay in usual classroom settings. Unlike virtual reality, users are not completely shut off from their environment instead, instead they view their environment normally but with an overlay of a digital world. The virtual learning as a result may engage a student fully, allowing him/her to be actively involved in the learning process instead of being a mere passive observer. Therefore, utilizing mixed reality tools and applications in introductory materials science courses presents educators with an opportunity to help students train their visuospatial abilities and improve their understanding of the 3D, complex material science concepts. The main objective of this ongoing work is to provide an innovative and interactive method to teach students threshold materials science concepts including miller indices and crystal structures. A case study is currently being carried out to implement the use of mixed reality systems in teaching these threshold concepts. The students will have full control over mixed reality 3D holograms, meaning: they can move them, scale them up or down, and, rotate them to look at fully explore them. We have developed a methodology to baseline the visuospatial skills of students. We will present our results on the effectiveness of these mixed reality tools in improving students visuospatial skills and the overall learning experience.
