Measuring the impact of learning with AI in Sierra Leone and beyond
AI Summary: A recent pre-registered trial demonstrated that AI, specifically the Guided Learning tool, can effectively enhance student learning without replacing teachers. The study, conducted in Sierra Leone, analyzed over 113,000 interactions and found that 91.4% of student conversations focused on building conceptual understanding, with the AI providing scaffolding questions in 76% of its responses. Quantitative results indicated significant gains in math scores, with students achieving 1.2 to 2.5 years of learning progress over an eight-week period, depending on the integration of the AI tool in lessons. The trial also revealed a shift in student behavior towards more engagement and a preference for understanding concepts rather than seeking direct answers, prompting plans for further research and the release of a teacher training guide to facilitate similar implementations.
