Plan Ceibal — Uruguay's national adaptive mathematics platform for primary education

Plan Ceibal began in 2007 as Uruguay's nationwide One Laptop Per Child programme. By 2013 it had developed PAM (Plataforma Adaptativa de Matemática), an AI-driven adaptive mathematics exercise platform progressively expanded to all students in primary grades 3-6 and lower-secondary grades 1-3, free at point of use.

To raise mathematics achievement by dynamically adjusting problem difficulty to each student's prior responses and by giving teachers dashboard analytics of class-wide and individual learning gaps.

PAM assigns maths problems adaptively with immediate automated feedback; teachers receive dashboards highlighting learning gaps to guide classroom intervention; Uruguay's near-universal device coverage from the original laptop programme removed typical access barriers to adaptive ed-tech.

An independent quasi-experimental longitudinal study by CINVE tracked 2,143 students across 237 public and private schools from 2013-2016 and found that greater PAM use was associated with a +0.20 standard-deviation gain in mathematics scores, with a larger effect for lower-socioeconomic-status students and no significant gender difference.

The effect size is described as modest, the evaluation window covers only 2013-2016, and no more recent randomised controlled trial has been published; results may not generalise beyond Uruguay's unusually high device saturation and public digital infrastructure.
