This article explores the potential value of mobile technologies in supporting work-based learning. The authors describe a small exploratory study that they conducted in health care education in which medical students work in hospital practice. The results reveal that co-assistants in both the survey and the pilot are most positive about the potential role of the PDA in searching for clinical information, such as reference books, guidelines or protocols, and rules of thumb. However, most co-assistants do not see the PDA as a valuable tool for communicating with others.
