An App that teaches math in record time 

It is a development carried out by the charity nonprofit Onebillion organization, originally aimed at helping children in Malawi, a country in southern Africa whose educational system is overloaded, with t average of 90 students per teacher.

The success of the experience led the director of the NGO, Andrew Ash and his team to replicate the development in more than 50 languages ??and divide it into two applications: Mathematics 3-5 years old and Mathematics 4-6 years old. 

Already successfully tested in England and other countries, Onebillion is a one-to-one teaching method which shortened the process of teaching in any school in the world carries between 12 and 18 months to six weeks. The program offers children devote 30 minutes a day to the tablet where the application is running. "The amazing thing was that they both countries have seen the same gain. A workweek in iPads, for 30 minutes a day equals three months of formal education. We are surprised," acknowledged at the University of Nottingham.

The application called the attention of researchers at the University of Nottingham, who wanted to see how effective was this app to enhance learning. 

It was subjected to a test, compared to traditional teaching, and found that the app improved the knowledge of mathematics on children to a much greater extent. 

Why is it so effective? 
Its makers say the app is simple, entertaining but also very rigorous. "Children are a constant stimulus to get a correct answer. That's really rewarding. And if they do it wrong, they can not progress. They have to get 10 out of 10 to pass and move to the next one" he admits. 

But he acknowledges that the tablet can not replace teachers: "It's just a way to supplement teaching by engaging children in a different way," he said. 

Teachers appreciate the help. They claim that in an ordinary class, is very difficult to teach because the classrooms are oversized and the lack of teaching materials, in contrast to the rooms where students are using the tablets. 

"They sit in silence, listening instructions through headphones in their language, calm and focused and interact with the screen," says one of them. 
The technology continues to find different ways to transform teaching methods and how children learn.
