Victor Piercey

Victor Piercey received his Ph.D in mathematics from the University of Arizona in 2012.  Dr. Piercey also holds a B.A. in Humanities from Michigan State University, a law degree from Columbia University with a certificate in international and comparative law, and a M.S. in Mathematics from Michigan State University.  He practiced law in the New York office of Weil, Gotshal, & Manges LLP for two years before returning to Michigan for a career in Mathematics.  Dr. Piercey began working as an assistant professor in the mathematics department at Ferris State University in the fall of 2012 and is currently an associate professor.  He is a co-founder of the Special Interest Group of the Mathematical Association of America (SIGMAA) dedicated to Inquiry-Based Learning, and currently serves as its chair-elect.  In addition, he chairs the SIGMAA dedicated to quantitative literacy, serves as four-year vice chair of the Michigan Section of the MAA, and is a member of the board for the journal Problems, Resources, and Issues in Mathematics Undergraduate Studies (PRIMUS).  He regularly uses inquiry-based learning and his legal experience to enhance his mathematics instruction and provide students with transformative experiences.   His current project is an inquiry-based sequence of courses entitled Quantitative Reasoning for Professionals, which is the result of collaboration with faculty in business, health professions, and social work funded by a grant from the National Science Foundation.  Some sections of this course are linked with sections of freshman writing courses.

Chris Rasmussen

Chris Rasmussen, Ph D., is Professor of mathematics education and Associate Chair in the department of mathematics and statistics at San Diego State University. He received his B.A., M.A. and Ph.D. from the University of Maryland in Mechanical Engineering, Mathematics, and Mathematics Education, respectively. After receiving his undergraduate degree he served as a Peace Corp Volunteer in Sierra Leone, West Africa. He is currently co-Editor-in-Chief of the International Journal of Research in Undergraduate Mathematics Education. His research investigates inquiry-oriented approaches to the learning and teaching of undergraduate mathematics, focusing on how mathematical ideas are developed through student exploration and teacher-student classroom discourse. His work in differential equations and linear algebra has led to methodological advances for coordinating individual and collective mathematical progress as well as instructional approaches that begin with students’ informal or intuitive ideas to progressively build more formal mathematics and the role of the instructor in this process. He has also been at the forefront of a national study of successful calculus programs, which has identified a number of programmatic features that are common among the programs identified as being more successful than peer institutions. Currently, he is co-PI on two national studies of the Precalculus to Calculus 2 sequence with the goal of better understanding current departmental practices related to these courses and the process of departmental and institutional change and ways that professional organizations can support and help sustain such change.
