The mathematics education research group at Oklahoma State University conducts educational research related to teaching and learning mathematics at the undergraduate level. Several members of our research team are involved in a statewide project to improve mathematics instructor professional development. Our group also includes practitioners who are serving as course coordinators and are involved with mentoring TAs and the preparation of preservice teachers.







Lee Ann Brown

Teaching Assistant Professor


Preparation for Calculus Course Coordinator

 160825 lee ann brown 001

Lee Ann Brown is a course coordinator for our Preparation for Calculus course. She mentors her TAs by leading weekly meetings, observing them as they teach and giving feedback. She is interested in improving her course to better prepare students for the Calculus sequence.

John Paul Cook

Assistant Professor

 160825 john paul cook 001

Dr. Cook's research program centers on investigating how students think about and learn concepts in abstract algebra. Particularly, he is interested in developing models of student thinking about particular concepts in abstract algebra, and then designing instructional sequences that are compatible with and leverage these ways of thinking. His other research endeavors include the mathematical preparation of pre-service teachers and the efficacy of the co-requisite instruction model.

Allison Dorko

Teaching Assistant Professor


Math Functions Course Coordinator

 171107 allison dorko 001

Dr. Dorko is interested in undergraduate mathematics eduction, specifically student learning from homework and student learning of calculus.

Cynthia Francisco

Teaching Assistant Professor


Math Structures and Geometric Structures for Elementary Education Course Coordinator

Lisa Mantini

Full Professor

 160906 lisa mantini 002

Dr. Mantini's research interests include groups, their actions as symmetries (of a shape in space, of the state space for a vibrating molecule or for the solutions to Maxwell's equations), and the matrix representations of these actions.  Lately she has become an origami enthusiast and is studying symmetric colorations of regular polyhedra and the corresponding representations of their symmetry groups.  Dr. Mantini's interests in mathematics education include the teaching and learning of collegiate mathematics, from studying what professors actually do in the college math classroom, to how we assess student work, to how students learn to read and write proofs. Lately her work has focused on the role of collaborative learning in the teaching of calculus.

Melissa Mills

Teaching Assistant Professor


Director of Mathematics Learning Success Center

 160825 melissa mills 002

Melissa is currently a Teaching Assistant Professor at Oklahoma State University and the Director of the Mathematics Learning Success Center. She has done research related to the teaching and learning of mathematical proof, in particular the way that mathematics professors use examples in their proof presentations. She is currently working with a newly established community of mathematics tutoring center directors to collaborate on research related to mathematics learning in tutoring contexts. In particular, she is focusing on tutor-student interactions.

Micheal Oehrtman

Full Professor


Michael Oehrtman received his PhD in Mathematics at the University of Texas at Austin in 2002 and is currently an Associate Professor in the Department of Mathematics at Oklahoma State University. His early research on calculus students' metaphors for reasoning about limit concepts originated Project CLEAR Calculus by idenifying approximations and error analyses as a potentially powerful and productive conceptual foundation for calculus. Dr. Oehrtman served as Co-PI and Project Director of the NSF Math and Science Partnership, Project Pathways (NSF award number 0412537, 12.5 Million over 5 years). Through Pathways and other projcets, Dr. Oehrtman has collaborated extensively with interdisciplinary faculty teams to develop graduate courses and professional learning communities for math and science high school teachers. Dr. Oehrtman co-authored a research-based precalculus curriculum and was co-PI on an NSF Math and Science Partnership Phase II grant (NSF award number 1050721, $2.1 Million over 3 years) to research the dissemination of these materials and faculty development in their use.

Michael Tallman

Assistant Professor


Calculus I Course Coordinator

 160825 michael tallman 001

Michael Tallman received his B.Sc. and M.A. in mathematics from the University of Northern Colorado and he received his Ph.D. in mathematics education from Arizona State University. Dr. Tallman has taught mathematics at the secondary and post-secondary levels. His primary research is in the area of mathematical knowledge for teaching secondary and post-secondary mathematics. Dr. Tallman's work informs the design of teacher preparation programs and professional development initiatives through an investigation of the factors that affect the nature and quality of the mathematical knowledge teachers leverage in the context of teaching. In particular, his research examines how various factors like curricula, emotional regulation, identity, and teachers' construction and appraisal of instructional constraints mediate the enactment of their subject matter knowledge.
