With the progress of ubiquitous computing technologies, ubiquitous learn ing is capable to give learners more effective and personalized education than the traditional one. On the other hand, safety education is necessary for children since accidents and crimes against them happen increasingly in recent years. The children might need to protect them by themselves. It is important for the children to learn safe ty knowledge through experiencing real dangers, which ar e not always realizable b ecause it m ay hu rt the children. In contrast, a virtu al experience is possible and popular to educate the children such as using computers; however, only virtual experiences might be insufficient for children to practice what they learnt in the real world. Therefore we propose a novel approach by fusing a real wo rld and virtual space to let a learn er have dual experiences in both real and virtual worlds. We design a platfo rm of du al experiencing learning and develop a safety education support system based on th e platform. Finally, we verify effectiveness o fu sing the system through experimental resu lts and the results are systematically analyzed with semantic differential and principle component analysis. The analyzed results show dual-experiencing learning with our system is especially effective for a motive of self-learning finally.
