Why revisit a skill after the first successful attempt?
Because a correct answer today is one snapshot. Spaced encounters create repeated opportunities to retrieve the same knowledge again after time has passed.[1]
How Toku uses this
Toku is designed around short repeatable sprints, so a skill can return across attempts rather than being treated as finished after one pass.
What research shows
Large reviews of memory research find a robust advantage for distributing repetitions over time rather than massing them together.[1]
Spacing has been applied beyond simple recall, including problem solving and generalisation, and can be combined with retrieval practice.[2]
Why this can matter for your child
Your child gets more chances to retrieve the same knowledge after time has passed, building a more durable pattern of access.
Toku returns to skills at useful intervals so your child has to remember them again rather than relying on immediate familiarity.
