Inter Brain Synchrony in Remote AR Education: Can Warming up Activities Positively Impact Educational Quality?

Previous education studies suggested that “warming up” activities featuring interpersonal synchrony components help improve educational quality and social closeness between teachers and students. While educators are eager to incorporate augmented reality (AR) into remote educational settings, prior research has not investigated the beneficial impacts of interpersonal synchrony on remote AR education. This study investigates the effects of prior physical synchrony (PS) on learning outcomes, inter brain synchrony (IBS), and social closeness in remote AR education. 41 participants were recruited for learning English vocabulary from a teacher. They conducted a movement learning task using prior PS and physical asynchrony (PA). The results showed that the positive effects of warming up activity on quiz score, IBS, and social closeness were observed in the PS section, but not in the PA section. Moreover, we found a high correlation between quiz score and IBS but not with social closeness. These results suggest that prior PS is a beneficial component of remote AR education and that IBS could be used as an index for evaluating educational quality. The implications of these results for remote AR education are discussed.
