Abstract: The rapid advance of wireless communication and sensor technologies has encouraged researchers to engage in the research issues of context-aware ubiquitous learning (u-learning). However, it is still not certain whether the new learning scenario is beneficial to students in a context-aware ubiquitous learning environment. In this study, a repertory grid-oriented mobile knowledge construction augmented reality learning system was developed for context-aware ubiquitous learning. To evaluate the effectiveness of the proposed approach, an experiment was conducted to probe the feasibility of the proposed learning strategy in comparison with learning strategies of different learning systems. The results reveal that the proposed approach can facilitate the acquisition of conceptions; moreover, incorporating AR technology had a potential positive effect on the learning achievements of the students in comparison with the conventional approach. Such findings offer good references for those who intend to design and conduct augmented reality technique based mobile learning activities.
