Why children forget, and how reviews fix it
Memory fades fastest in the first days and weeks after learning. Reviewing just before it fades (spaced repetition) and recalling the answer yourself (retrieval practice) are two of the best-researched ways to make learning last.
Shield Recharge: spaced repetition as a rescue mission
On the IvySity world map, a chapter your child has mastered fogs over after 14 days and cracks after 30. A 90-second Shield Recharge replays its three hardest questions, putting first the ones your child got wrong before. Passing restores the chapter and earns bonus XP and Guild War points.
Teach Pixel: learning by explaining
Explaining an idea in simple words shows what you really understand (the Feynman technique). Pixel, the study pet, asks children to explain why an answer is right in one to three sentences. AI gives a short, kind tip and Pixel grows as they teach. Explanations are not stored.
The Mistake Lab: every error comes back once more
Every wrong answer is saved and returns as a Fix-the-Glitch puzzle. Children see the answer that went wrong, try again with the hint, and earn coins when it's fixed, so mistakes become part of learning instead of something to hide.
Common questions
How often should children revise a chapter?
A short review a couple of weeks after learning, and again about a month later, helps it stick. IvySity prompts this automatically with Shield Recharge after 14 and 30 days.
Is the Mistake Lab visible to other children?
No. Mistakes are private to your child and your family account, and are deleted when you delete the child's profile.
