Stephen Hegedus, Ph.D.

Stephen Hegedus is Professor of Mathematics and Mathematics Education (with tenure) at the University of Massachusetts Dartmouth, PI/Co-PI of a three presently funded SimCalc projects—one funded by the U.S. Department of Education, Institute of Education Sciences and two funded by the National Science Foundation, with previous appointments as Research Fellow and Lecturer at the University of Oxford, UK. He is also Director of the James J Kaput Center for Research and Development in Mathematics Education at his Institution. His PhD in Mathematics Education was from the University of Southampton, UK. His present work is in the development and study of dynamic software environments in wirelessly connected classrooms with associated curriculum to develop students’ understanding of fundamental mathematical ideas. This work also involves the professional development of pre- and in-service teachers and the integration of innovative technologies into K-12 curriculum. He has also directed a State Mathematics and Science Partnership improving teacher content knowledge and growth within an entire district of grade 4-8 teachers. Research interests also include the evolution of signs and symbols in mathematics learning for which he runs a renowned international working group, (with support by the NSF) and the role of metacognition in advanced mathematical thinking. He has published and presented numerous papers and workshops at local, national and international venues.
