Playing a daily computer game has helped a class of primary school children improve their maths and concentration, a study says.
The children played the game every day for 10 weeks with "dramatic" results.
A class from the Dundee school took part in the project to show how computer games can enhance and build on classroom learning.
It is now hoped the resource can be used more widely across schools in the Scottish city.
The 30 children from St Columba's primary school - all aged nine and 10 played Dr Kawashima's More Brain Training game on a Nintendo DS console every morning before lessons for about 15 minutes.
