LLAMA LIMA: A Living Meta-Analysis on the Effects of Generative AI on Learning Mathematics

The capabilities of generative AI in mathematics education are rapidly evolving, posing significant challenges for research to keep pace. Research syntheses remain scarce and risk being outdated by the time of publication. To address this issue, we present a Living Meta-Analysis (LIMA) on the effects of generative AI-based interventions for learning mathematics. Following PRISMA-LSR guidelines, we continuously update the literature base, apply a Bayesian multilevel meta-regression model to account for cumulative data, and publish updated versions on a preprint server at regular intervals. This paper reports results from the first version, including 15 studies. The analyses indicate a small positive effect (g = 0.31) with a wide credible interval [0.06, 0.58], reflecting the still limited evidence base.
