The concept of mobile learning was proposed by Revans from England in 1982 which has been more than 25 years (Revans, 1982). Revans offers an iterative model, successively alternating experience and preparation/reflection, which is a useful paradigm for mobile learning (McDermott et al., 2000). However, scholars perceive mobile learning in different ways. The following section contributes to various explanations of mobile learning by international scholars: m-learning is e-learning through mobile computational devices: Palms, Windows CE machines, even your digital cell phone (Quin, 2001). Mobile learning is a context-based learning by using mobile technology medium and is learner-centered. The flexibility of mobile learning in a proper location allow learners to interact with other learners and instructors and conduct technology-learning, content learning or context-based learning that is proactive, instant, distant /approximate, individual or group-centered. Moreover, learner will experience meaningful knowledge construction through this process (Young et al., 2005). Mobile learning is defined as any educational provision where the sole or dominant technologies are handheld or palmtop devices (Traxler, 2005).

This study focuses on how to develop an effective online learning platform as a developing basis of digital learning materials for museum guiding course. A new learning mode of mobile guiding system will be proposed with example of the printing collections of National Science and Technology Museum. The museum digital resources will be converted into digital learning materials which can be used by the museum's volunteer tour guides through multimedia and mobile carrier. Such platform will be helpful for museum volunteer tour guide training and their self-growing. It will further provide museum visitors more autonomous learning environment.
