This study was conducted to test the effect of the augmented reality-based program on the motivation, attention and conceptual skills of preschool children. The research was conducted according to the pretest-posttest control group quasi-experimental design: 13 participants (6 girls, 7 boys) in the experimental group and 13 (5 girls, 8 boys) in the control group, a total of 26 children (4-5 age group) were included in the study. While the children in the experimental group participated in the applications prepared with augmented reality, the children in the control group were practised upon with the traditional teaching method. In the research, measurement tools were applied to the working groups (experiment-control) both before and after the application. As a result, it was determined that the motivation, attention and concept skills of the children in the experimental group increased significantly compared to the children in the control group. The results show that augmented reality applications can be used in learning activities in preschool education.
