Dyscalculia Day Webinar

To mark international Dyscalculia Day on 3 March, 2026, EDA is delighted to host this free webinar on Dyscalculia with Dr Giannis Karagiannakis, a leading international expert on dyscalculia and maths difficulties. This 90 minute webinar aims to promote evidence-based understanding of dyscalculia through real educational practice, longitudinal data, and collaboration between researchers, educators, and families, in alignment with the mission of the European Dyslexia Association (EDA).

Webinar Title: From Math-Profile to Practice: Comprehensive Assessment and Ecological Intervention in Dyscalculia

Abstract

Dyscalculia is a heterogeneous neurodevelopmental specific learning difficulty, requiring assessment and intervention approaches that extend beyond single-score testing and isolated skill remediation. Contemporary consensus within the European Dyslexia Association emphasizes the need for comprehensive mathematical–cognitive profiling that captures both domain-specific numerical processes and domain-general cognitive functions.

This webinar presents a longitudinal, school-based examination of dyscalculia through anonymized case studies of students meeting diagnostic criteria for dyscalculia, followed over a two-year period within mainstream educational settings. Drawing on the framework proposed by the EDA Academic Dyscalculia Committee, the session outlines the core components of a comprehensive dyscalculia profile, including number sense, symbolic processing, arithmetic reasoning, executive functions, visuospatial skills, and learning dynamics over time.

Participants will be guided through how assessment data are translated into individualized, ecologically valid intervention programs embedded within everyday classroom practice. Using anonymized case studies implemented through the MathPro framework, the webinar illustrates how systematic profiling supports instructional decision-making, continuous adaptation of teaching strategies, and the monitoring of learning trajectories across time.

The presented cases demonstrate how sustained, data-informed intervention within authentic school contexts can support meaningful mathematical development in students with dyscalculia when assessment and instruction are treated as an integrated, evolving process.
