- Systematic Review

Artificial intelligence (AI) is assumed to individualise learning, yet no quantitative synthesis has examined what happens when the intervention targets students with Down syndrome (DS). The review presented here analyses this effect and the extent to which the interventions are linked to Universal Design for Learning (UDL). This study employs a mixed-methods systematic review design, prospectively registered on the Open Science Framework and reported in accordance with PRISMA 2020 (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Searches were conducted in Scopus, Web of Science, APA PsycInfo, and ERIC; studies suitable for pooling were analysed using Hedges’ g under the Knapp–Hartung random-effects model, while the remaining studies were included in a structured narrative synthesis. A large pooled point estimate was found (g = 2.00; 95% confidence interval (CI): −0.89 to 4.90), though it was imprecise, and heterogeneity ranged from moderate to high (I2 = 64.9%); the certainty of the evidence was very low. The eight remaining studies consisted of pilot tests, single-case studies, or designs lacking a control group. The findings indicate improvement following the intervention but offer no recommendations. There are more tools available than evidence of their effectiveness; this review outlines what needs to be measured to determine that.
