Victor Cifarelli

Victor Cifarelli (Ph.D., Mathematics Education, Purdue University) is an Associate Professor of Mathematics and the Coordinator of the Mathematics Education Program in the Department of Mathematics at the University of North Carolina at Charlotte. His doctoral research focused on the role of reflective abstraction as a learning process in mathematical problem solving. His current research examines how solvers reflect on and test the viability of their evolving intuitions, and transform their initial hypotheses and conjectures into actual solution activity. Dr. Cifarelli has presented his research at AERA, PME, and PME-NA. His articles have appeared in the Journal of Mathematical Behavior, Focus on Learning Problems in Mathematics and the Proceedings of PME and PME-NA. Over the past several years, he has been an active contributor to SIG/RME as a reviewer and presenter of research papers. In addition to his research interests, Dr. Cifarelli has demonstrated an on-going commitment to the professional development of mathematics teachers. He has taught a variety of undergraduate and graduate mathematics and mathematics education courses including mathematics for elementary education majors, mathematics education for elementary and middle school education majors, and graduate mathematics courses for secondary mathematics teachers. He has co-directed a pair of projects for elementary, middle, and secondary grades mathematics teachers under the Eisenhower Professional Development Program and also has conducted numerous in-service workshops for middle grades and secondary mathematics teachers.
