The Education Endowment Foundation (EEF) has published the independent evaluation report of a trial of a maths-based learning app.

The “onebillion” programme consists of two maths learning apps, Maths 3–5 and Maths 4–6, that are designed to reinforce basic mathematical skills learned in the classroom. The apps are aimed at pupils aged 3–5 and 4–6 respectively and consist of mathematical activities organised around different topics such as counting, shape and measures. The trial, conducted by researchers at the University of Oxford, tested the impact of the apps on pupils in Year 2 who had been identified by their teachers as being in the bottom half of their class in maths at the start of the school year.

One hundred and thirteen schools from across England took part in the randomised controlled trial. Schools in the intervention group used the apps for half an hour, four days per week, for 12 weeks, in addition to regular maths lessons. All children started with the Maths 3–5 app and progressed to the Maths 4–6 app, once they had completed Maths 3–5. The children’s use of the apps was monitored by teaching assistants who were trained by a team from the University of Nottingham. Pupil achievement in maths was measured using the Progress Test in Maths 6.

Pupils who received the programme made significant additional progress in maths (effect size = +0.24) compared to the control group. However, the trial also suggested that there may have been a negative impact (effect size = -0.10) on pupils eligible for free school meals (FSM) compared to those in the control group, though this finding was non-significant. The report advises that teachers or school leaders using onebillion should carefully monitor the impact on FSM pupils if implementing the approach.
