Luis RadfordLuis Radford is professor at the School of Education Sciences at Laurentian University in Sudbury, Ontario, Canada. His research interests cover both theoretical and practical aspects of mathematics thinking, teaching, and learning. His current research draws on Lev Vygotsky's historical-cultural school of thought, as well as Evald Ilyenkov's epistemology, in a conceptual framework influenced by Emmanuel Levinas and Mikhail Bakhtin, leading to a non-utilitarian and a non-instrumentalist conception of the classroom and education.
Radford is an editor of the education journal For the learning of mathematics. In 2011 he was the recipient of the Hans Freudenthal Medal of the International Commission on Mathematical Instruction for his "development of a semiotic-cultural theory of learning".
He is the editor of book series "Semiotic Perspectives in the Teaching & Learning of Math" with Springer Verlag. Provided by Wikipedia
