The purpose of this study was to investigate the effects of augmented reality (AR) technology on the achievements, self-efficacy beliefs and views of paramedic students in electrocardiography education. In the study, mixed methods including quantitative and qualitative methods were used. The sample of the study included a total of 71 first-year paramedic students studying at a university in Turkey. An academic achievement test, self-efficacy scale, and semi-structured interview form were used as data collection tools. As a result of the study, it was found that AR had a significant medium effect on students' academic achievements but did not have any effect on their self-efficacy beliefs. In addition, based on the interviews conducted with the students in the experimental group, it was determined that the students were satisfied with the use of AR in their courses and wanted to use this technology in different courses and subjects in the future.
