  • Augmented Reality (AR) provides new possibilities for simulating teaching environments, experiencing teaching processes andpromoting teaching interaction through certain teaching approaches, including virtual-real blended, real-time interactive or three-dimensional immersive. This paper first briefly introduces the present research status of implementing AR in education and thenillustrates the 3D AR learning environment and the long-distance augmented video system. Furthermore, we explain a specific casein which the convex lens image-forming experiment was adopted as the material and we conducted an interactive and integratedimage-forming experiment using AR technology to improve teaching. The case study was mainly to investigate the learningattitudes of the experimental group students by using AR instructional applications and to compare the difference in the learningachievements of eighth graders with the convex lens image-forming experiment in two learning environments. The mean scores ofthe experimental group increased more significantly than the mean scores of the control group; however, there appeared to be nosignificant difference in the mean scores between the two groups in post-tests. In addition, most students were found to havepositive attitudes towards using AR for their learning in physics courses: they believe that AR instructional applications hold theirattention and increase their learning motivation in physics courses. The results show that this learning environment that blendsreality with virtuality will greatly stimulate the learning interests of students and promote their level of activity, suggestingsignificant potential for this learning application in practice.
