Augmented reality technologies have been widely used in the field of education as well as in many other fields. Thus, it has attracted attention of many researchers. However, studies show different results regarding the effects of augmented reality on cognitive load and achievement. In the context of this study, the effect of using augmented reality and the summarizing strategy, which is one of the productive learning strategies, on students' cognitive load and success was investigated. In this study, a quasi-experimental design with a pretest - posttest control group, which is one of the quantitative research methods, was used. The participants of the study consist of 3rd year students studying in the Emergency Aid and Disaster Management Department of the Faculty of Health Sciences at a state university in the fall semester of the 2022-2023 academic year. During the study, 17 of the 34 students were assigned to the experimental group and 17 to the control group. As a data collection tool, a personal information form was used to determine the demographic characteristics of the participants, an achievement test to determine the effectiveness of the applied method, and a cognitive load scale to determine the cognitive load. During the experimental application, the students in the experimental group were asked to use augmented reality, which describes the content of a topic, together with the summarization strategy, while the students in the control group were asked to use augmented reality, which describes that. According to the findings, it was concluded that the achievement scores of the students in the experimental group showed a significant difference compared to the students in the control group. This means that the students in the experimental group had higher success. Furthermore, it was observed that the cognitive load of the students in the experimental group was lower than that of the students in the control group.
