Malawi teaches UK children a lesson
An app originally developed to help teach Malawian schoolchildren maths has also boosted the learning of children in the UK, according to a study.
Researchers at Nottingham University subjected the onebillion app to a randomised control trial, testing it against other teaching apps and against no app.
In both Malawi and in the UK, researchers found the onebillion app helped to greatly boost children's maths knowledge compared to the other options.
Education in Malawi is often basic - classes of 90 pupils are normal and some children have to share one teacher with 300 classmates.
