their teaching. It can also be of value to business people, e.g. sales representatives who do not wish to waste time away from their busy schedules to attend formal training events. Podcasting Podcasting consists of listening to audio recordings of lectures. It can be used to review live lectures and to provide opportunities for students to rehearse oral presentations. Podcasts may also provide supplemental information to enhance traditional lectures . Psychological research suggests that university students who download podcast lectures achieve substantially higher exam results than those who attend the lecture in person (only in cases in which students take notes) . Podcasts may be delivered using syndication, although this method of delivery is not always easily adopted . Work M-learning in the context of work can embrace a variety of different forms of learning. It has been defined as the "processes of coming to know, and of being able to operate successfully in, and across, new and ever-changing contexts, including learning for, at and through work, by utilizing mobile devices". M-learning for work M-learning at and through work Cross-contextual m-learning Learning for work, which could be also described as 'just-in-case' learning, involves classic and formal education activities, such as training courses, that prepare learners for future work-related tasks. A typical, corporate application is the delivery of mobile compliance training, which can be seen as a viable means to reach geographically mobile employees, such as consultants or staff in logistic and transport systems. Another application is mobile simulations that prepare learners for future situations, for example, real-time SMS-based simulations for disaster response training. Learning at and through work, which could be labeled as "just-in-time" mobile learning, occurs in informal education settings at the workplace. Employees can use the mobile phone to solve problems via handheld devices in situ, for example by accessing informational resources (such as checklists and reference guides) before customer visits or mobile decision support systems. The latter is popular in clinical settings where they support highly mobile medical staff through rule-based algorithms in the decision regarding more complex patient cases. Their application was associated with learning and in particular with practice improvement of medical staff. Learning through work also occurs by interacting with distant peers via phone. "People tagging" is an approach whereby people assign topics they associate with co-workers. The aggregation of interests and experiences serves not only as a means to raise awareness but also
