Background

Dr. Teresa Magnus is a Professor of Mathematics and the Director of the Mathematics program at Rivier University. Hired in 1998, she has taught a broad range of courses, including Abstract and Linear Algebra, Discrete Mathematics, Problem-Solving and Modeling, Geometry, Calculus and Functions, core curriculum and developmental mathematics. She has advised the University’s undergraduate research projects in algebraic coding theory, hyperbolic geometry, and mathematical voting theory. 

Dr. Magnus’ research areas include both mathematical content and mathematical pedagogy.  She has published on the relationship between geometric structure and coordinate rings, and she has explored applications of discrete mathematics to voting and cryptography. Her passion for teaching has influenced her recent work in curriculum development, active learning, and alternative assessment. She continues to explore how active learning can improve access to, understanding of, and retention of mathematics. Currently, Dr. Magnus is writing an online, open-source, interactive geometry textbook, “Polyominos, Polygons, and Polyhedra: Discovering Geometry through Explorations”, which encourages students to develop a deeper understanding of the foundations of geometry through active learning and hands-on exploration using both tactile and virtual manipulatives.  

Dr. Magnus continues to be active in the New Hampshire Teachers of Mathematics organization, where she served as President from 2020-22 and as a Board Member from 2007-23. Before arriving at Rivier, she taught mathematics at Saint Mary’s College (Ind.), Albion College (Mich.), and Sweet Briar College (Va.).

Academic Philosophy

Mathematics is an important subject for engagement in society today, not just for technical applications, but also for understanding our world, discerning truth, and making personal and civic decisions. All students are capable of learning mathematics if they are open to growth. We learn mathematics by exploring possibilities, trying out strategies, and sharing our discoveries. Mistakes are welcome in mathematics; they often lead to new insight and deeper understanding. 

Unfortunately, our traditional way of teaching mathematics tends to emphasis speed over thought and perfection over understanding. Dr. Magnus strives to provide students the opportunity to explore ideas that are new to them, to appreciate that multiple strategies may solve a problem, to experience the thrill of solving a challenging mathematical puzzle, and to develop the skills and confidence to use mathematics throughout their lives.
