Educational technologies are a central component of the blended learning concept, ie a mixture of classroom and online courses, with which the Fraunhofer Academy has been working for many years. These can be entire learning environments in which the course participants can organize their entire training, or accompanying educational technologies such as mobile learning apps or learning games, which support the learners selectively in their knowledge acquisition. Individual steps in the education process can also be facilitated by learning technologies, such as assessing one's own prior knowledge through e-assessment systems.
