Digitalization is a core issue in training. This article introduces the main forms of digitalization and animation of digital devices by comparing their conditions of use. The combination of face-to-face and distance learning courses beats distance learning alone in terms of efficiency. As a demonstration, we propose a classification of digital devices according to four criteria: the level of interactivity; efficiency; the breadth of skills developed; and the ability of learners to use the knowledge acquired in a practical setting. This typology makes it possible to argue that, despite the diversity of technological tools, blended learning or game-based learning are favored because they enable experimentation and collaborative role-playing. Nonetheless, the effectiveness of the digitalized tools depends greatly on the respect of some fundamental principles that must be integrated into their design and in particular into the animation of the training. Generally speaking, a classic or online course is effective as long as it is tailored to the needs of its audience and focuses on a humanized training combining quality animation, interactivity, and a reflexive approach.
