Dyscalculia is a multifaceted neurodevelopmental disorder involving persistent and unexpected difficulties in understanding numbers, retrieving mathematical facts, performing calculations, and reasoning mathematically. Its roots often lie in both domain-specific deficits—such as numerical magnitude and symbol processing—and domain-general functions including working memory, inhibition, visuo-spatial reasoning, and language. In this keynote, Marie-Pascale Noël and Giannis Karagiannakis bridge research and clinical practice, presenting a comprehensive framework for understanding and assessing dyscalculia. A live demonstration of the MathPro Test will illustrate how a learner’s mathematical–cognitive profile can be accurately mapped, offering a clear example of how diagnostic information can guide both educational and clinical decision-making. Building on this foundation, the talk will then explore how assessment results can inform targeted intervention using the Flexplicit Instruction model—combining explicit, heuristic, and math flexibility strategies to strengthen mathematical understanding and promote long-term learning success.
