The aim of this study is to investigate how the use of augmented reality (AR) applications in educational environments affects students’ achievement levels. The study was carried out through two dimensions; a quantitative and a qualitative aspect. The study was conducted with 7th-grade students in a public secondary school in Turkey as part of a science course. For this purpose, AR applications and activities were implemented that were suitable for the topic of Astronomy. The quasi-experimental model and one of the quantitative research methods were used for the study. As data collection instruments an achievement test and an interview form were made use of. AR activities were used for teaching in the experimental group, while the traditional method for the control group. The quantitative results of the study showed that there was a significant difference in the achievement level of learners in favor of the experimental group. The interviews with the students revealed that the AR applications used in the course were interesting, that they increased interest, desire, and motivation in class, and that they facilitated learning. However, students indicated that the cost of the AR materials was high, that they had difficulty in obtaining the materials, and that they sometimes had technical problems. Another limitation was expressed as that the excess the number of students makes it more difficult to take the advantage of AR activities. Students suggested that lowering the cost of AR materials and using them in other lessons can be more effective in learning environment.

This research aims to present the general situation of scientific publications in the WoS database dealing with wearable technologies in terms of security and privacy from a comprehensive and holistic perspective. A total of 71 publications were reached within the scope of the research by going through various screening processes. Document analysis method was used to collect the data, and content analysis method was used for the analysis. The results of the research show that there has been a steady increase in the number of publications on this subject since 2015. In particular, it has been observed that 86.8% of the publications have been published in the last five years. In addition, it has been revealed that the most publications on the subject are in the fields of "Computer Science", "Engineering", "Telecommunications" and "Science Technology". On the other hand, it has been seen that the concept of Security is used more than the concept of Privacy in the fields of Computer Science, Telecommunications and Engineering. In addition, when the keywords of the publications are mapped, it has been seen that the words "Wearable Technologies", "Security", "Privacy", "Internet of Things", "Authentication" and "Attack" are used more frequently.
