Using the Augmented Reality 3D Technique for a Convex Imaging Experiment in a Physics Course

Abstract

Augmented Reality (AR) provides new possibilities for simulating teaching environments, experiencing teaching processes and promoting 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 then illustrates the 3D AR learning environment and the long-distance augmented video system. Furthermore, we explain a specific case in which the convex lens image-forming experiment was adopted as the material and we conducted an interactive and integrated image-forming experiment using AR technology to improve teaching. The case study was mainly to investigate the learning attitudes of the experimental group students by using AR instructional applications and to compare the difference in the learning achievements of eighth graders with the convex lens imageforming experiment in two learning environments. The mean scores of the experimental group increased more significantly than the mean scores of the control group; however, there appeared to be no significant difference in the mean scores between the two groups in post-tests. In addition, most students were found to have positive attitudes towards using AR for their learning in physics courses: they believe that AR instructional applications hold their attention and increase their learning motivation in physics courses. The results show that this learning environment that blends reality with virtuality will greatly stimulate the learning interests of students and promote their level of activity, suggesting significant potential for this learning application in practice.
