Hippolyte Gros is an Associate Professor in cognitive sciences at CY Cergy Paris University. With a focus on cognitive and educational psychology, his research interests include problem-solving, numerical cognition, arithmetic reasoning, cognitive flexibility, mathematics education, and educational myths. During his PhD, he investigated the interpretative processes at play in arithmetic reasoning and word problem-solving. More specifically, he studied the role of daily-life knowledge on the encoding of numerical information, the representation of arithmetic word problems, and the use of solving strategies. In an effort to identify how to foster transfer from one learning situation to another, he gathered both behavioral data (success rates, response times, problem drawings, etc.) and physiological data (saccadic eye movements, pupil dilation) in several activities ranging from pro- blem classification and analogy making to sentence recall and group reasoning. He worked with children, teachers, and math experts to show the universal nature of some reasoning biases. He is now looking to further investigate this issue from an intercultural perspective. Ultimately, his work aims at developing new teaching strategies to be used in schools.
