Google has shared findings from classroom studies in the UK and Italy examining Gemini’s use in mathematics tutoring and lesson planning.

In the UK, Google and education platform Eedi conducted a 10-week randomized controlled trial involving more than 1,100 students aged 12 to 15. Students received static hints, support from a human tutor, or interactive AI tutoring that combined Eedi’s resources with Gemini. Teachers monitored progress, and human experts reviewed every AI response before it reached a student.

Google reports that students receiving AI tutoring performed similarly to those receiving human tutoring on in-platform tasks and intermediate quizzes. Expert reviewers approved 95% of AI responses, compared with 76% in an earlier study. Google also said Gemini guided students rather than giving direct answers in nearly 99% of sessions. However, gains reported in classroom tasks and quizzes did not appear in STAR standardized test scores during the trial. Google said students completed fewer problems with AI tutoring because step-by-step support took longer.

In Italy, a yearlong study across 31 schools collected information from 1,600 teachers representing more than 24,500 students. Google said teachers using Gemini to co-design lessons reported a 38% reduction in traditional front-of-class lectures, while student-led collaborative learning nearly tripled. Reported student engagement rose from 77% to 84%.

Google said it is exploring follow-up UK trials covering a full academic year.
