When learning with the onebillion software, gains in ability have been shown to be consistent over time, across different cohorts of children, between different countries, and assessed by different groups of researchers. This demonstrates that consistent and reliable learning gains can be achieved with this education technology regardless of context.

After 10 weeks, results showed children made significant mathematical learning gains with the apps, for both languages of instruction, compared to standard practice.
Pupils who received onebillion made an additional three months' progress in maths compared to the control group.

Despite a brief time using the onebillion maths apps, of just eighteen 30-minute sessions on average across the 14-month study period, girls’ attainment in mathematics was similar to that of boys. In contrast, for usual, class-based, teacher-led instruction, girls started to lag behind boys in learning mathematical skills.

and the other four finalist apps were evaluated in a 15-month trial with 2,700 children in Tanzania, to determine the efficiency of the software in a community setting.
At the beginning of the Global Learning XPRIZE field test, less than 10% of the participating children could read a single world in Swahili. After the field test, 45% of these children could read a word, with 30% reading full sentences.

The most significant outcome of this study was the huge improvement in learning and test performance made by those students in the experimental group who had struggled on the pre-test.

Our results showed that using the maths apps helped close the gap in achievement between low-achieving children and their relatively higher achieving peers.In four controlled, pilot studies, we found young children in the UK who used the maths apps made strong immediate and sustained mathematical learning gains.

We found that children made significant progress in learning basic mathematics and suggest this technology can provide an alternative means of education for these children.Our results showed children with special educational needs and disabilities were able to interact with the tablet device and maths app software when delivered without additional assistive technology aids.

We suggest the onebillion maths apps can be used as part of a well-balanced early years curriculum.In the first randomised control trial of the onebillion maths in the UK, we found significantly greater learning gains in mathematics when children used the maths apps either as a supplementary intervention or instead of a regular daily maths activity, in comparison to standard mathematics practice only.

In the first randomised control trial of the onebillion maths in Malawi, we found the maths apps supported significant learning gains in mathematical skills over and above standard face-to-face mathematics practice or using tablet devices without the onebillion maths software.
