The important ingredient is time between encounters. Some forgetting is allowed to happen, so the next retrieval has to rebuild access rather than rely on immediate familiarity.
Why spacing can help memory
A large quantitative literature finds that distributed practice generally produces stronger later retention than massed practice.[1]
Spacing and retrieval can work together
Reviews suggest that combining spaced encounters with active retrieval can make practice particularly efficient.[2]
How spacing changes with the skill
Spacing can vary with how difficult the material is, how well the child knows it and how long the knowledge needs to remain accessible.[1]
