The concept of the atom can be visualized in different ways in the mind due to its structure, which the naked eye cannot see. Augmented reality (AR) is one of the applications that can be used to teach such concepts. This study aimed to investigate students' views on the use of AR applications in teaching. Phenomenological design, one of the qualitative research designs, was used in the study. The study group consisted of 26 -graders in a public secondary school. AR application was organized to teach the structure of the atom. Within the scope of the study, an interview form consisting of four open-ended questions prepared by the researchers and submitted to expert opinion for content validity was used as a data collection tool. When the students' answers to the questions were examined, it was determined that they had positive opinions that AR application could be used in other courses and different subjects, that this application was more instructive because it concretized the subject, that it caused a better understanding of the subject it was used in, and that it increased participation in the lesson due to the possibilities of providing three-dimensional images. Suggestions were made based on the results.eninfo:eu-repo/semantics/openAccessAugmented realityatomic structuresecondary school studentsstudent views.Article28455410.30786/jef.16098831332071WOS:001542202400004Q4
