Ubiquitous Teaching Assistant for Location-based Learning

Using software agents to assist students in virtual learning environments has become increasingly common for many experimental programs. Therefore, this work proposes a framework to establish ubiquitous teaching assistant (u-TA). The proposed u-TA framework provides several system modules for different virtual learning environments and also supports the multi-modal user interfaces, such as Web-based and instant messenger-based interfaces. With the development of ubiquitous learning, u-TA should also consist of good mobility for guiding students and answering students' questions on mobile handheld devices. Therefore, this work uses the u-TA framework to construct a location-based service (LBS) learning system to introduce the essence of courses to students and help them browse the content of the course resources on campus. We gave a case study for using the proposed system to promote the Service-Learning courses in Feng Chia University, Taiwan. The experimental results show that the proposed u-TA system can enhance the understanding of Service-Learning courses for students and
