Theoretical foundations and implications of augmented reality, virtual reality, and mixed reality for immersive learning in health professions education.

ABSTRACT

BACKGROUND: Augmented Reality (AR), Virtual Reality (VR) and Mixed Reality (MR) are emerging technologies that can create immersive learning environments for health professions education. However, there is a lack of systematic reviews on how these technologies are used, what benefits they offer, and what instructional design models or theories guide their use. AIM: This scoping review aims to provide a global overview of the usage and potential benefits of AR/VR/MR tools for education and training of students and professionals in the healthcare domain, and to investigate whether any instructional design models or theories have been applied when using these tools. METHODOLOGY: A systematic search was conducted in several electronic databases to identify peer-reviewed studies published between and including 2015 and 2020 that reported on the use of AR/VR/MR in health professions education. The selected studies were coded and analyzed according to various criteria, such as domains of healthcare, types of participants, types of study design and methodologies, rationales behind the use of AR/VR/MR, types of learning and behavioral outcomes, and findings of the studies. The (Morrison et al. John Wiley & Sons, 2010) model was used as a reference to map the instructional design aspects of the studies. RESULTS: A total of 184 studies were included in the review. The majority of studies focused on the use of VR, followed by AR and MR. The predominant domains of healthcare using these technologies were surgery and anatomy, and the most common types of participants were medical and nursing students. The most frequent types of study design and methodologies were usability studies and randomized controlled trials. The most typical rationales behind the use of AR/VR/MR were to overcome limitations of traditional methods, to provide immersive and realistic training, and to improve students' motivations and engagements. The most standard types of learning and behavioral outcomes were cognitive and psychomotor skills. The majority of studies reported positive or partially positive effects of AR/VR/MR on learning outcomes. Only a few studies explicitly mentioned the use of instructional design models or theories to guide the design and implementation of AR/VR/MR interventions. DISCUSSION AND CONCLUSION: The review revealed that AR/VR/MR are promising tools for enhancing health professions education, especially for training surgical and anatomical skills. However, there is a need for more rigorous and theory-based research to investigate the optimal design and integration of these technologies in the curriculum, and to explore their impact on other domains of healthcare and other types of learning outcomes, such as affective and collaborative skills. The review also suggested that the (Morrison et al. John Wiley & Sons, 2010) model can be a useful framework to inform the instructional design of AR/VR/MR interventions, as it covers various elements and factors that need to be considered in the design process.
