The MMB institute has asked e-learning-experts for their opinion about further changes in digital learning. The significant trend, especially from an economic view, is the so-called mobile learning. This master thesis explains the concept of mobile learning especially in occupational training. The main question in this thesis is: What does mobile learning mean in the setting of occupational training and how important is it? Despite the significant importance of occupational training and its long history, there is no uniform definition of this term. In this master thesis, the following definition is used: Occupational training means those trainings which are at least partially financed from the learners organization. Next to classic occupational trainings, e-learning becomes important as well. Moreover, in this day and age, mobility gains an unprecedented relevance. Therefore, mobile technologies are being integrated in occupational training. The process of learning takes place not only in physical classrooms, but also location- and time-independently. Via mobile devices learners are served with learning contents, which they need in an exact moment. Nevertheless, there is no uniform definition for mobile learning either. Hence, in this master thesis the following definition is used: Mobile learning means all learning processes, which are supported by mobile devices. The connection between mobile learning and occupational training is shown via practical examples. The digital world brings an immense range of possibilities to gain information, to communicate, to collaborate and to reflect. Digital media opens a new spectrum of methods for knowledge transfer, so that the requirement of occupational training grows.
