As the rapid development of technology and the popularity of computer equipments, Computer aided learning makes learning effective and interesting through the use of interactive multimedia technology. In the past decade, augmented reality has become an popular technology and has widely utilized in many researches. Many researchers have integrated AR technology into multimedia instructional practices, increasing instructional flexibility and interaction. However, most of augmented reality learning system didn't have the learning scaffold or method to support learning activity, and often been designed from the perspective of developers, without considering the instructors' instructional progress and methods. Therefore, this study proposed an concept-mapping augmented reality learning system whose architecture and implementation are detailed. To evaluate the effectiveness of the proposed system, a questionnaire was given to 36 eleven years old students after their hands-on experience with the system. Results of the questionnaire showed that the proposed AR learning system support students a motivating, pleasant, and satisfying learning experience. Limitation, conclusion and future studies are given.
