This study presents a systematic review of literature on the application of augmented reality (AR) in professional training contexts published between 2001 and 2020. A total of 49 articles were selected after a two-stage screening process, and key research findings were analyzed and synthesized using a coding scheme comprising five inter-related aspects: basic information, instructional contexts, technology features, instructional design, and research results. The review results depict the trend patterns in AR-supported professional training in terms of publication, research paradigm, and technological affordances, and report the contextual differences in AR pedagogies and instructional functions over time. Furthermore, a meta-analysis was conducted in the present study to examine the overall effectiveness of AR application in professional training, with the results indicating an overall small effect size (g = 0.268) and nine significant moderating factors. Informed by the review and meta-analysis results, a set of implications for facilitating and investigating AR-supported professional training are proposed and discussed.

With its ability to afford immersive and interactive learning experiences, virtual reality has been widely used to support experiential learning, of which the learning effectiveness is promoted by the instructional component of debriefing. The current literature on debriefing mainly focuses on the traditional learning contexts while little is known on its effectiveness in immersive virtual reality (IVR) learning environments. Based on the theories of experiential learning and debriefing, this study designed a debriefing strategy based on simulated learning experience and investigated its effectiveness on knowledge and behavioral learning in an IVR learning program, using a randomized controlled trial with 77 elementary students from Hubei province in China. The study results support the efficacy of IVR on improving knowledge acquisition and behavioral performance, and reveal a significant moderating effect of debriefing on the effectiveness of IVR learning environments. The study confirms the critical role of debriefing in IVR-based instruction and provides theoretical and practical implications for the design and implementation of effective IVR learning environments.
