AI Learning Impact Study in Sierra Leone

Students in classrooms where their teachers incorporated Gemini into roughly half their lessons to meet a target of 12 hours during the trial saw even higher gains—roughly 1.8 to 2.5 years of progress.

this represents roughly 1.2 to 1.7 years of typical learning progress achieved within the eight-week trial.

Students using Guided Learning saw a gain of +0.258 standard deviations in their math scores compared to the control group.

Today, we are sharing the results and technical report from a randomized controlled trial (RCT), conducted in partnership with Fab AI and with the support of the Sierra Leone Ministry of Education 1 . Over eight weeks, we evaluated how Guided Learning in Gemini affected the math…
