Ubiquitous mobile computing and the advances in wireless telecommunication networks have encouraged significant growth of mobile learning in recent years. Since mobile learning can take place at anytime and anywhere, there is an advantage to integrate the real world objects into learning contents. Mobile devices have characteristics that include location awareness and hardware diversity. Thus, there are needs and opportunities to provide mobile learners with adaptive learning experience. To implement adaptive mobile learning, it is essential that the learning contents are context sensitive to be retrieved through the adaptation mechanism built in the learning management system. In this paper, an adaptive learning content generation platform is presented. We adopted the 5R adaptation framework to provide the mobile learning system the capability of providing the right content to the right learner, through the right device, in the right location, and at the right time. We provide an example to demonstrate how to use the platform to create adaptive learning contents.
