M-learning is the approach of using mobile device to help users engage with learning content. M-learning software exists, but does not have high uptake. This could be the lack of a model that inherited the design guidelines from learning theories. One such learning theory relevant to mobile learning is Transactional Distance Theory (TDT). TDT identifies a number of key aspects and the concept of transactional distance. The research contributes an analysis of how TDT guides the design of mobile learning application. This research also contributes an evaluation to access proof-of-concept mobile learning prototype on their ability to engage learners.
