In order to make his CM1/CM2 students understand concentration, Maître Fafa isnpired himself of the work of Jean-Philippe Lachaux, a neuroscience researcher, whose research has led to the Atole program and the concept of brain cells.
First, Master Fafa explains the concept of chief neurons to his students: there is a first intention, like doing homework. In order to accomplish this task, the child must focus his head neurons on it and not allow his attention to be distracted by any distraction. Concentration is important and allows the child to define his priorities.
To apply this method, Master Fafa ask his students to do exercises independently.
Before, they felt that they weren't necessarily at work, that they weren't concentrated, but they couldn't understand what was bothering them. Master Fafa
