This is no more than a natural evolution from their traditional responsibility for the production of PowerPoint slides and handouts which support most classroom events. I am becoming increasingly aware of the the need to make clear a distinction between the broad concept of digital learning content, in all its many varieties, and the much narrower idea of interactive tutorials of the traditional CBT (computer-based training) variety. While some trainers will have the aptitudes and interests which will help them to excel in this area, in most cases this will remain a job for specialists.
