DeepMind measures AI learning effects in Sierra Leone school trial
Google DeepMind says a randomized controlled trial across 12 schools in Sierra Leone and 1,763 junior secondary students found that guided AI learning lifted mathematics scores by 0.258 standard deviations. The result reinforces a broader shift in edtech: AI tools will increasingly be judged by learning outcomes, not by novelty or usage alone.
