Spaced Repetition - the secret to success

A very helpful blog from Donald Clark about the successful implementation of spaced repetition. We've blogged before about how Number.fy enables the teacher to have high density of practice and by combining this with regular, daily, practice (aka spaced repetition), children can achieve astonishing results.

A class of 30 children can easily play 24,000 questions in a school-day month - that's a lot of (spaced) practice and more importantly, it is instantly marked so a teacher can target where practice is needed and clearly demonstrate the impact of the practice as the children improve over time.
