Pure face-to-face training is increasingly being supplemented or even replaced by modern forms of learning such as blended learning, online training, e-learning and informal learning. What does this mean for you as a trainer (lecturer, speaker, personnel developer)? This reference book shows how the job description of the trainer is changing due to digitalisation and which competences you need as a trainer to be successful in the "learning revolution". After all, specialist knowledge paired with classroom didactics is no longer enough. This work takes you by the hand to become a learner again as a trainer and to develop into an "agile learning facilitator". It gives you orientation in the digital "trainer competence jungle". In a practical and clearly understandable way, you will receive both theoretical background knowledge and practical implementation possibilities for the modernisation of your continuing education programme.
