PRESENTATION
With a background in Cognitive Sciences (Bachelor, M.S. & PhD), Psychology (AA degree) and Computer Science (DUT & Bachelor), Hippolyte Gros is an Associate Professor in Cognitive Sciences at CY Cergy Paris University.
In a cognitive and developmental perspective, he is interested in interpretative processes at play in arithmetic problem solving. More specifically, his work focuses on the role of world knowledge on the encoding of numerical information, the representation of arithmetic word problem and the use of solving algorithms.
In order to better understand how to foster transfer from one learning situation to another, he studies the semantic determinants of mathematical abstraction. The methods he uses to study arithmetic reasoning include analogy, transfer, solving, drawing, classification, solution evaluation, problem creation and problem recognition tasks. His work studies all types of arithmetic reasoning, ranging from children’s strategies to mathematical experts’ limitations and proficiencies. Ultimately, his work aims at developing new teaching strategies to be used in ecological contexts.
