How this product was evaluated?By offering ethical, equitable, and inclusive, high-quality, effective content, that is beautifully curated and delivers joyful learning experiences within a safe and protected learning sanctuary, onebillion enables marginalised children to develop holistically, successfully acquiring foundational skills that form the bedrock for future, life-long, learning. Our short term outputs include improved learning outcomes in maths and reading, as evidenced by 9 Randomised Controlled Trials to date.
onecourse shows a proven positive impact, backed by at least one experimental study that shows a statistically significant positive impact on the intended learning outcomes.
Different levels of research evidence indicate the reliability of the proof of positive impact. The solutions featured in the Learning Cabinet range from:
There have been 9 RCTs to date on onebillion's software. These have consistently shown that onebillion’s software produces positive and significant learning gains in literacy and numeracy, and that girls learn at the same rate as boys.
Recommended use
We can tailor the length of session for different contexts, school timetables and age ranges, but typically onecourse is being used for 40 minute sessions by individual children. We aim for children to get 40 minutes per day, 5 days a week, although in practice school absenteeism may reduce this.

Target audience
To enable all children to reach their potential in foundational numeracy and literacy and develop a love of reading, through a holistic approach to joyful learning and early development skills.
onecourse is delivered to the child in 30–40 minute daily lessons, which cover both literacy and numeracy. Each lesson is created for that child, based on their level, using a pool of thousands of learning units. It gives both structured learning and exploratory play opportunities each day.
In onecourse we combine a phonics approach to teaching reading with exposure to a wide variety of illustrated stories. We begin with sound differentiation practice, before letter sounds are met, first without and then with their corresponding letters. Letters and their sounds are met in an order which allows us to introduce syllables and single-syllable words that children can decode by themselves, as soon as possible. Gradually, children meet more complex words, simple phrases and sentences, and single-paragraph stories, until eventually they are reading stories by themselves, with help where it is needed. Spelling, reading aloud and writing – by hand and typing – are taught both as individual skills and to enhance and embed learning.
The numeracy strand takes children from the basics of early numeracy, from sorting objects, to introducing numbers, counting, adding and subtracting, and early multiplication and division. We begin with the basics of sorting, matching and comparing objects. This lays the groundwork for introducing the words for numbers and allowing children to develop number sense with objects. The numerals are introduced gradually, with lots of practice. This allows children to establish their understanding of numbers before they can confidently differentiate values. Once children have a confident grasp of numbers to 10, they learn simple addition and subtraction, first using pictorial objects, before meeting equations with numbers and symbols. The course progresses through counting to 20, 50, 100 and finally up to 1000, with plenty of practice. Children are taught different methods to help with addition and subtraction, including finger counting and number lines. Word problem activities allow them to put their learning in real world contexts. Throughout the course, children experience numbers in different ways to solidify their understanding and to gain tools that will help them in different scenarios. They learn to count in 2s, 5s and 10s; identify number patterns; and do basic division and multiplication. onecourse also introduces children to 2D shapes, initially through early work on patterns. Later they are introduced to shape names and learn identifying features such as numbers of sides and corners.
Stories help provide context for learning, broaden and deepen vocabulary, teach crucial soft skills such as empathy, and reflect the child’s world while providing a window to others. Children meet stories each time they use onecourse.
We have a Learning-through-Play approach in onecourse, by which each design choice is informed by a criteria of being joyful, meaningful, iterative, actively engaging and socially interactive.
onecourse is designed to be intuitive to use by first-time tablet users, with extra tuition in touchscreen interaction for those who need it. A friendly digital teacher supports children throughout, ensuring they never get stuck in an activity, and gives feedback and encouragement. We design through a lens of neurodiversity, including using clean visuals and clear instructions to avoid sensory overload.
We have a continual feedback loop with one of our scaling partners, Imagine Worldwide, with whom we support a number of government-owned onecourse projects. Data collected by baseline and endline assessments as well as government- and Imagine-led observations of implementations are instrumental in making improvements to the software and to the implementation.
Originally onecourse was developed in Chichewa for Malawi. Our focus has been largely on Sub-Saharan Africa, although we have also been supporting scaling partners in Asia and the Americas.
onebillion charges a one-off $5 per tablet software licence fee. At our discretion, we may waive this fee in order to support scaling programmes, research projects, and smaller partners for whom this may be a barrier.
Yes.
In Malawi, the government owns a programme which is the national rollout of our onecourse software to every primary school in the country. This is known as the BEFIT programme, currently in the 3rd year of rollout and reaching approx 1 million children as of Sept 2025.
In addition to external research consistently showing that boys learn at the same pace as boys with onecourse, the research has also shown increased self-confidence and school attendance.
