On November 1, 2026, the implementation of the DATARIUM project – Data Thinking and Reasoning In Understanding the Meaning – began. The project is funded under the Erasmus programme, specifically the KA220-SCH Cooperation Partnerships in School Education action. The project coordinator is the University of Primorska (Slovenia), and the partners are the University of Florence (Italy) and the University of Rijeka (Faculty of Mathematics).

The DATARIUM project aims to strengthen statistical literacy in early compulsory education (ages 6 to 11) by developing a shared, research-informed conceptual framework for early statistical literacy grounded in statistical thinking. The project supports teachers in adopting inquiry-based and inclusive practices and promotes early data literacy in line with European priorities for key competences and lifelong learning. The project will develop a shared conceptual framework for early statistical literacy and translate it into curriculum-aligned learning activities and educational resources for primary education. The learning activities will be piloted and evaluated in partner schools across participating countries. Teachers will participate in structured training and collaborative exchange, supported by open educational resources to ensure effective implementation and transferability. DATARIUM will deliver a piloted and refined conceptual framework for early statistical literacy, a set of classroom-tested, curriculum-aligned learning activities, and trained teachers capable of implementing inquiry-based and data-informed classroom practices. All outputs will be openly accessible, supporting long-term sustainability, scalability, and adoption across diverse educational contexts.
