One Phone Classroom helps Ghanaian teachers teach every child at the right level, even when the whole class shares a single phone. In many Ghanaian public primary schools, one class has 40 to 50 children and almost no devices. A single Basic 5 class can hold children still working at Basic 2 level. Apps built for one child per device miss these children entirely. One Phone Classroom brings Teaching at the Right Level (TaRL), a proven approach of grouping children by what they can do rather than by their class, into these classrooms with one closed loop: 1. Place. The teacher photographs each child’s exercise-book work. Meta’s Muse Spark reads the handwriting, finds what the child has mastered and where they first go wrong, and places them on a four-step ladder (Beginner, Developing, Approaching, Proficient). The ladder is mapped to Ghana’s NaCCA curriculum. 2. Group. Children are grouped by level, not by class. 3. Teach. Each group gets a video, an interactive worksheet and a quiz at its level. Muse Spark drafts them and the teacher approves them. 4. Phone Day. One phone per group is enough: a parent’s phone or the teacher’s. The group watches and works together, then each child takes their own quiz turn. Scoring 80% moves a child up a level. 5. Regroup. The teacher’s board updates live. It shows who moved up, who is stuck and on which skill, and suggests peer helpers. It works with 1 phone, and better with 7. One Phone Classroom is part of Nikasemo’s mission to give every Ghanaian child learning that meets them where they are. Nikasemo already works with 50+ schools, 30,000 learners and 2,000+ teachers across Ghana. One Phone Classroom is built to roll out through that network, starting with the classrooms that have the fewest devices. The levels and quizzes it produces feed directly into Learnn, Nikasemo’s learning platform. As schools gain devices such as the Nikasemo Pad, each child moves from a shared phone to a personal learning plan built from the same data.
