Two Studies Show AI Tutoring and Classroom Tools Deliver Measurable Learning Gains
Google DeepMind released results from two randomized controlled trials demonstrating that AI-assisted instruction improves student outcomes and reduces teacher administrative burden. The findings come as the company expands teacher training programs across India and Africa.
Math Scores Jump in Sierra Leone Trial
Researchers conducted an eight-week study with 48 classrooms and nearly 1,800 students in Grades 7 and 8 across Sierra Leone. Half the classrooms used Guided Learning, an AI tool grounded in learning science. The other half continued with standard instruction.
Students using the tool scored 0.26 standard deviations higher on externally validated assessments covering fractions, exponents, and prime numbers. That gain equals roughly 1.2 to 1.7 years of typical learning progress in low-and-middle-income countries.
Engagement exceeded typical EdTech adoption rates. Sixty-nine percent of students reached the intended 12-hour usage threshold, with an average of 15 hours of tool use per student. Students who hit the recommended usage target saw even larger gains of 0.38 standard deviations - moving an average student from the middle of their class to the top third.
Italian Teachers Report 70% Less Time on Admin Work
A separate study across the Don Bosco school network in Northern Italy tracked 700 educators and 9,000 students from primary through vocational college. Teachers used Gemini for Education to create content and scaffold lessons.
Results showed 80-99% of students in each class mastered planned lesson skills, from geometry to Java programming. Teachers reported a 70% reduction in time spent on administrative tasks. They redirected that time to one-on-one mentorship and emotional support.
Teacher Training Expands to India and Africa
Google is rolling out AI literacy programs targeting millions of educators. In India, the company is partnering with governments in Maharashtra, Chhattisgarh, Assam, Ladakh, and Punjab to offer mobile-first training customized for school educators.
The program will be available in six languages in its first year: Assamese, Hindi, Marathi, Telugu, Odia, and Punjabi. The company plans to scale to additional states, higher education institutions, and regulatory bodies.
A partnership with the African Union Commission will bring AI literacy training to university students and faculty across all 55 Member States. The initiative starts at institutions including Kwame Nkrumah University of Science and Technology and the University of Ghana, with no-cost product training and onboarding for administrators and faculty.
