Emerging from e-learning, mobile learning is going to be a significant next wave of learning environments. This is an evolving research area and many issues regarding mobile learning have not yet been exhaustively covered. This article focuses on implementing m-learning modules using a simple case study. Most existing typical e-learning systems are tailored toward PC based web access and are not customized to be used through mobile devices such as Personal Digital Assistants (PDAs). In addition, the content developed in most of these systems is not standardized, making reuse rather difficult. We discuss here an architecture and prototype of a mobile learning system. The system performs adaptation based on the device and user profiles. The system therefore works on both PC and mobile platforms. The article also describes the underlying multidimensional adaptation framework, which is used to develop the prototype mobile learning system described in this article.
