Mathematics Education Research Group
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.
Faculty
 Lee Ann Brown
Preparation for Calculus Course Coordinator
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
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 preservice teachers and the efficacy of the corequisite instruction model.
 Allison Dorko
Math Functions Course Coordinator
Dr. Dorko is interested in undergraduate mathematics eduction, specifically student learning from homework and student learning of calculus.
 Cynthia Francisco
Math Structures and Geometric Structures for Elementary Education Course Coordinator
 Lisa Mantini
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
Director of Mathematics Learning Success Center
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 tutorstudent interactions.
 Michael Oehrtman
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 CoPI 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 projects, 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 coauthored a researchbased precalculus curriculum and was coPI 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
Calculus I Course Coordinator
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 postsecondary levels. His primary research is in the area of mathematical knowledge for teaching secondary and postsecondary 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.
