## AI overview

The article reports results from a randomized controlled trial in Sierra Leone examining Gemini's Guided Learning feature. Students using the tool improved their math scores by 0.258 standard deviations compared with a control group, equivalent to roughly 1.2 to 1.7 years of typical learning progress over eight weeks. The study also found that students primarily used the tool to build conceptual understanding, while teachers remained central to lesson design and classroom facilitation.
