On 20th May at the Google offices in London, fresh evidence from Sierra Leone relating to quality assurance for AI in education in LMICs (low-to-middle-income countries) was presented during . The study (linked below), “Teaching with Gemini: Measuring the impact of Guided Learning on student mathematics progress in Sierra Leone” is one of the first major research studies exploring the impact of AI-supported learning in a low-income education setting.
Over eight weeks, nearly 1,800 Junior Secondary School students across Sierra Leone participated in a randomised controlled trial exploring how Gemini-powered Guided Learning could support maths learning outcomes.
The findings are significant.
Students using the tool demonstrated substantial improvements in externally validated maths assessments, with learning gains equivalent to approximately 1.2–1.7 years of typical progress in low- and middle-income countries in just eight weeks. Engagement levels were high, illustrating the importance of strong, local implementation.
As in-country implementation and data collection partners, working with Fab AI, Gates Foundation, Google DeepMind, Laterite, Oxford MeasurEd, EducAid contributed practical, on-the-ground expertise and experience to explore how emerging AI tools may support learning responsibly in Sierra Leone.
Importantly, this work helps ensure that the future of AI in education is shaped by schools, educators, and learners in multiple contexts. Too often, conversations around innovation and emerging technologies happen without the perspectives and realities of lower-resource contexts being represented. This study helps change that.
We are thrilled that Sierra Leone is leading the way and contributing directly to the rapidly-evolving global evidence base on the future of learning.
Thank you to all of EducAid’s team, especially (Ibrahim Alhaji Fortune, LA, Miriam Mason, Erin Northey) partners Fab AI - Ignacio Roman Muñoz, Jared Lee, María José Ogando Portela, Natalia Valdes Aspillaga, Paul Atherton, Tomas Koutecky and Usman Khawar, schools, teachers, and students involved in this important work.
The event included important insights and inspirational words from Ben Piper, Dayoung Lee, Conrad Sackey - Minister of Basic and Senior Secondary Education, Irina Jurenka, Wongani Grace Nkhoma-Sankofa, Paul Atherton.
