A key aspect of professional noticing includes attending to students’ mathematics (Jacobs et al., 2010). Initially, preservice teachers (PSTs) may attend to non-mathematics specific aspects of a classroom before attending to children’s procedures and then, eventually their conceptual reasoning (Barnhart & van Es, 2015). Use of 360 videos has been observed to increase the likelihood that PSTs will attend to more mathematics-specific student actions. This is due to an increased perceptual capacity, or the capacity of a representation to convey what is perceivable in a scenario (Kosko et al., in press). A 360 camera records a classroom omnidirectionally, allowing PSTs viewing the video to look in any direction. Moreover, several 360 cameras can be used in a single room to allow the viewer to move from one point in the recorded classroom to another; defined by Zolfaghari et al., 2020 as multi-perspective 360 video. Although multiperspective 360 has tremendous potential for immersion and presence (Gandolfi et al., 2021), we have not located empirical research clarifying whether or how this may affect PSTs’ professional noticing. Rather, most published research focuses on the use of a single camera. Given the dearth of research, we explored PSTs’ viewing of and teacher noticing related to a six-camera multiperspective 360 video. We examined 22 early childhood PSTs’ viewing of a 4th grade class using pattern blocks to find an equivalent fraction to 3/4. Towards the end of the video, one student suggested 8/12 as an equivalent fraction, but a peer claimed it was 9/12. The teacher prompts the peer to “prove it” and a brief discussion ensues before the video ends. After viewing the video, PSTs’ written noticings were solicited and coded. In our initial analysis, we examined whether PSTs attended to students’ fraction reasoning. Although many PSTs attended to whether 8/12 or 9/12 was the correct answer, only 7 of 22 attended to students’ part-whole reasoning of the fractions. Next, we examined the variance in how frequently PSTs switched their camera perspective using the unalikeability statistic. Unalikeability (U2) is a nonparametric measure of variance, ranging from 0 to 1, for nominal variables (Kader & Perry, 2007). Participants scores ranged from 0 to 0.80 (Median=0.47). We then compared participants’ U2 statistics for whether they attended (or not) to students mathematical reasoning in their written noticing. Findings revealed no statistically significant difference (U=38.5, p=0.316). On average, PSTs used 2-3 camera perspectives, and there was no observable benefit to using a higher number of cameras. These findings suggest that multiple perspectives may be useful for some, but not all PSTs’. 

Scholarship on extended reality (XR) in teacher education is emerging at an increasing rate. As additional forms of XR become more common in the profession, there is a need for teacher educators to consider how the various forms of XRbased representations of practice are conceptualized. The papers in this special issue of JTATE on XR in teacher education each define XR in similar ways, but often with different terminology. In this editorial, we note how such definitions are characteristic of much of the good scholarship on XR in teacher education. With this in mind, this editorial focuses on how the field may begin to consider defining XR within the boundaries of perceptual capacity—a concept that align with definitions in various other professional fields and with theory and practice in teacher education. 

One of the most disruptive aspects of 2020 for teacher education, mainly due to COVID, was the loss of field placements for future teachers. Teacher educators attempted to respond to this gap with videos of exemplary practice—something used commonly in teacher education to supplement such field experiences. Teacher educators, however, should have learned about the potential and promise for the use of 360 video for teaching and teacher education. This chapter highlights the research behind the use of 360, also showcasing how it has been used successfully in mathematics teacher education and physical education teacher education. The chapter includes evidence supporting the use of 360 as a dissemination technique and a technology skill needed to be taught to current and future teachers. Finally, evidence is provided to suggest that the use of 360 should be continued even when field placements return fully face-to-face. 

The use of video is prevalent in teacher education. it has been shown to be successful in varied content areas, with multiple contexts, and for differing audiences. Even with its successes, there are several known challenges with capturing and using classroom video to inform teacher professional development and preservice teacher education. To address these issues, drawing on a grant from the National Science Foundation, we have created an extended reality initiative (XRI) that provides information about equipment, software tools to edit single and multi-perspective videos, and a collection of videos for instant use in preservice and in-service classrooms. In addition to the deliverable outcomes, the project has shown that 360 and VR can improve preservice teacher noticing through increased perceptual capacity. 

Research has provided evidence of the value of producing multiple representations of content for learners (e.g., verbal, visual, etc.). However, much of the research has acknowledged changes in visual technologies while not recognizing or utilizing related audio innovations. For instance, teacher education students who were once taught through two-dimensional video are now being presented with interactive, three-dimensional content (e.g., simulations or 360 video). Users in old and new formats, however, still typically receive monophonic sound. A limited number of research studies exist that have examined the impact of combining three-dimensional sound to match three-dimensional video in learning environments. The purpose of this study was to respond to this gap by comparing the outcomes of watching 360 video with either monophonic or ambisonic audio. Results provided evidence that ambisonic audio increased perceived presence for those familiar with the content being taught, led to differentiation in what ambisonic viewers noticed compared to monophonic groups, and improved participant focus in watching the 360 video. Implications for the development and implementation into virtual worlds are discussed. 

The global COVID-19 pandemic has disrupted normal face-to-face classes across institutions. This has significantly impacted methods courses where preservice teachers (PSTs) practice pedagogy in the field (e.g., in the PreK-12 classroom). In this paper, we describe efforts to adapt an assignment originally situated in a face-to-face school placement into a virtual version. By utilizing multi-perspective 360 video, preliminary results suggest virtual field experiences can provide PSTs with similar experiences for observation-based assignments. Acknowledging that immersive virtual experiences are not a complete replacement for face-to-face field-based experiences, we suggest virtual field assignments can be a useful supplement or a viable alternative during a time of the pandemic.
