We present a case study on the use of mixed reality (MR) spatial computing in a fully remote classroom. We conducted a 10-week undergraduate class fully online, using a combination of traditional teleconferencing software and MR spatial computing (Magic Leap One headsets) using an avatar-mediated social interaction application (Spatial). The class culminated in a virtual poster session, using Spatial in MR to present project results, and we conducted a preliminary investigation of students experiences via interviews and questionnaires. Students reported that they had a good experience using MR for the poster session and that they thought it provided advantages over 2D video conferencing. Particular advantages cited were a stronger sense that they were in the presence of other students and instructors, an improved ability to tell where others were directing their attention, and a better ability to share 3D project content and collaborate.
