In recent years, with great development in information technology (IT), more and more ITs have been applied to learning now to break through limitation of conventional teaching environment, and improve learning willingness and effectiveness of learners. Because of popular wireless network and mobile carriers, students are never constrained to time and location nowadays, such that more attention is paid on u-learning (ubiquitous learning). In order to improve learning diversity, excursion has become one of the approaches to facilitate conventional classroom teaching. Thus, an earthquake disaster prevention learning platform is developed by employing radio frequency identification technology in combination with APP and handheld mobile devices. It is applied in 921 Earthquake Museum of Taiwan. With the context-awareness technology and guiding of the system, learners may utilize the mobile device to receive the information of exhibits in the museum for them to learn in context. Moreover, earthquake and disaster prevention knowledge are created effectively by means of context link of knowledge learnt in the museum, course materials and life. Additionally, assessment mechanism is created based on school materials and reference books, based on which the learning processes of learners are also recorded in the research. On one hand, learners can review themselves in the system; on the other hand, the teacher can adjust teaching according to such learning process to improve teaching effectiveness. At last, the learning style proposed by Felder & Silverman (1991) is used in the research to study whether there are different performances and effects for learners of different learning styles in such context learning.
