CEASAR is an NSF-funded research project that explores how a multi-device learning platform (combining immersive technologies and tablets) can promote collaborative learning in college introductory astronomy courses. Initially, we developed a virtual reality (VR) version to explore how collaborative learning could take place within this immersive environment. Building on that foundation, the project shifted its focus to comprehend the affordances of immersive augmented reality (AR) technologies for supporting collaborative learning in STEM classrooms. To support this evolved direction, we crafted a robust night sky simulation that's accessible from both tablet computers and HoloLens 2 headsets. Undergraduate students collaborate in this multi-device environment, tackling challenges like determining the location of a fallen space capsule using only star views from the crash site. Our research has spanned numerous classrooms, both at a partnering community college and a university. The rich multimodal data we've gathered are instrumental in shedding light on the effective integration of XR technologies into intricate collaborative learning tasks. This process involves merging logfile data from the simulation with videos of the collaborating students. As a culmination of the CEASAR project, we aim to establish design principles for creating efficient multi-device STEM learning activities and offer methodological guidance for research on technology-enhanced collaborative learning.
