This research delves into the influence of Augmented Reality (AR) on Science, Technology, Engineering, Arts, and Mathematics (STEAM) education within the domain of primary school teacher training at the university level. The core aim is to augment digital literacy within the primary education framework through inquiry-based teaching methods. This investigation was organized among students enrolled in the Faculty of Education, Comenius University in Bratislava. The empirical research is devoted to the contribution of AR technologies to the enhancement of STEAM education and its implications for future primary education teachers. Utilizing a qualitative research methodology, the study facilitated small-group project work among students, complemented by focus groups and interviews to garner comprehensive insights into their experiences and perceptions. The findings of this study illuminate the significant role of AR applications for enriching STEAM education, manifesting in motivation of future teachers and the advancement of specific STEAM competencies. The results indicate the advantage of the integration of AR technologies in educational settings as a tool for supporting digital, technical, and artistic skills among students. The research results are possible to use in the innovation of teacher training primary education study program. An interdisciplinary approach towards STEAM education can help future teachers to navigate and to understand a technologically driven world effectively. Furthermore, the study offers actionable recommendations for practicing primary school educators on the implementation of AR-based pedagogical strategies to enrich the learning experience. By doing so, it aims to bridge the gap between traditional educational methodologies and the demands of contemporary digital literacy, ultimately fostering a more engaging and effective learning environment for future generations. The research results will be implemented into the STEAM oriented subjects into the primary school teacher training at the university level and in the lifelong learning of the in-service primary school teachers from educational practise.
