+0.26SD in 8 weeks
Because of AI (plus tablets and pair work), junior secondary students in Sierra Leone gained about 0.26 standard deviations in math in eight weeks.
A preregistered classroom-level cluster RCT of 1,763 Grade 7–8 students in 48 classrooms across 12 Port Loko schools had treatment classes use Gemini's Guided Learning in pairs for about two of four weekly math lessons; the treatment group gained +0.258 SD on independently administered tests.
