Augmented reality (AR) is a new technology that acts as a bridge between real world and virtual environment by providing synchronous interaction. Virtual objects can be added on real world through this technology. In other words, during recording of the real world with the camera, AR uses pre-determined target points in real world by connecting virtual objects and interpreting the results through certain programs . AR can distinguish itself from other technologies by combining virtual and real objects, by providing real-time interaction, and by involving 3D objects [1, 2]. AR is an increasingly popular technology that can be used on different platforms such as desktop, laptop computers, portable devices, and smartphones . Applications developed with AR technology allow use of 3D objects, texts, images, videos, and animations, and this technology provides the use of them together at the same time . Therefore, users can naturally interact with events, information, and objects [5, 6].
With the development of software and hardware used in AR, this technology has begun to be used in many areas such as entertainment, marketing, military, medicine, engineering, psychology, and advertising [1, 3, 7]. Thanks to AR’s advanced technology, related applications have been transformed from a blank area into a rich learning experience . This situation leads AR technology to be used in education area. It is known that technological tools used in education provide new opportunities to increase interaction of learners and to learn by enjoying, making the learning process more active, effective, meaningful, and motivating [9, 10, 11]. AR technology has also attracted attention in education field with its ability to allow interaction with virtual and real objects, to learn by doing, and to increase attention and motivation . AR offers many advantages when used in education and provides educational gains. While enabling rich interaction , AR provides a natural experience, enhancing attention and motivation [14, 15]. In addition, it enhances interpreting, problem solving , and creative thinking skills  and provides flexibility for students . Although AR technology provides significant contributions, there are still many problems that need to be addressed. The first of these problems is the difficulty of developing and implementing content for AR applications. It is known that many teachers and learners are biased to use AR, especially because of technical knowledge requirement in 3D object development . In addition, external factors such as light, output, and image quality negatively affect the applications. Students who use AR may have to use more than one device. It requires them to have spatial orientation, collaborative skills, problem-solving skills, and ability to intervene in this technology . Besides the technical and pedagogical problems that AR brought with, the potential of having educational applications has led researchers to this field.
When literature is examined, it is observed that many studies have been carried out for the use of AR applications in education. Yilmaz  categorized advantages of AR, gains achieved, and learning approaches it supports and they are presented in Table 1 in detail.
