Repetition is the foundation of Effective Learning. Now, repetition can be boring and discouraging, or it can be focused on preparing vocabulary, structures, expressions, and content that, once implemented in the real context of a meeting or a presentation, it has a practical continuity. Such continuity is what makes us assimilate learning effectively, and motivates us to acquire future knowledge.
