The Development Team
Judith E. Jacobs began her teaching career as a junior high school, then high school, mathematics teacher in Brooklyn, NY. She has been both an education professor and mathematics professor, having taught content, methods, and mathematics education courses at the undergraduate and graduate levels for elementary, middle, and high school teachers. For the past 35 years, Judith has designed and conducted numerous professional development programs, both large scale, multidistrict as well as school/district based, for teachers at all levels K-12. Upon her retirement from California State Polytechnic University Pomona, she founded JEJMath, Ltd through which she continues her work in mathematics education.
Judith has been active professionally at the local, state, and national levels. She is a founding member of both the Association of Mathematics Teacher Educators (AMTE) and Women and Mathematics Education (WME) and has served in leadership roles in these organizations. She also has served on the Board of Directors of the National Council of Teachers of Mathematics (NCTM). Judith continues to make presentations at these, and other, professional meetings.
Dave Kennedy is Associate Professor of Mathematics at Shippensburg University of Pennsylvania. He teaches elementary mathematics content courses and secondary mathematics methods courses, and supervises student teachers. He also has taught elementary mathematics methods and has conducted numerous professional development programs for both elementary and secondary mathematics teachers. He was a multi-subjects elementary classroom teacher and a junior-high mathematics teacher in the California public schools. Dave has presented at both national and international conferences of AMTE, NCSM, NCTM, Joint Mathematics Meetings of the AMS and MAA, and T3.
Yvonne Lai is an Assistant Professor at the University of Nebraska-Lincoln in the Department of Mathematics. She has taught capstone mathematics courses for secondary teachers at the University of Michigan and at the University of Nebraska-Lincoln. Additionally, she has taught secondary mathematics methods at the University of Michigan. She holds a PhD in mathematics (specializing in spaces of actions of Coxeter groups on n-dimensional hyperbolic space) and subsequently held post-doctoral positions with the Department of Mathematics and then with the School of Education at the University of Michigan. Her research area is mathematical knowledge for teaching. She has presented her work at conferences including AMTE, RUME, AERA, and JMM.
Diana Sherman’s love of teaching mathematics began during her undergraduate studies at Mount Holyoke College in South Hadley, MA. She completed a four-year teacher preparation program taking many courses in mathematics content and pedagogy with SummerMath for Teachers. She taught elementary school, grades 3 and then 4, for five years, gaining insight about student thinking and learning in mathematics. Diana transitioned to graduate school, earning her Master’s of Science Degree in elementary mathematics from Central Connecticut State University in New Britain, CT. She completed her doctorate in mathematics education at the University of Michigan in Ann Arbor, MI in 2016. In her work as a course and field instructor, she has prepared preservice elementary teachers to teach mathematics. Diana has taught both content and methods courses in elementary mathematics where she supports novices’ learning to do mathematics and to enact the practices necessary for skilled mathematics teaching. She is currently an assistant professor, teaching in the Education Department at Saint Anselm College in Manchester, NH.
