## Biography

Kyeong Hah Roh’s primary research interest is in undergraduate students’ cognitive development in advanced mathematics with particular attention to mathematical logic and argumentation. She has developed curricular materials and instructional interventions for proof-oriented undergraduate mathematics courses such as advanced calculus, geometry, and mathematical proofs. She has conducted teaching experiments to implement these educational innovations for student-centered, inquiry-based, learning. Her research aims not only to help students have deeper understanding of mathematics and mathematical practice but also to help mathematics teachers support their students’ learning of advanced mathematics topics and mathematical representations.

## Education

- Ph.D. Mathematics Education, The Ohio State University 2005
- Ph.D. Mathematics, Seoul National University, S. Korea 2000
- M.S. Mathematics, Seoul National University, S. Korea 1995
- B.S. Mathematics Education, Ewha Womans University, S. Korea 1993

## Research Interests

The overall goals of my research in mathematics education are (1) to better understand undergraduate students intuitive understanding of abstract mathematics concepts, (2) to use the knowledge gained to develop educational innovations for the teaching and learning of proof-oriented mathematics courses, and therefore (3) to bridge gaps between the lower division and upper division of undergraduate mathematics courses. I have conducted research on discovering how undergraduate students develop their intuition and visual reasoning while learning definitions of limits and continuous functions. Using the knowledge gained from my research, I have developed educational innovations for mathematical logic, proving structures, and formal definitions of advanced calculus topics. My current research focuses on (1) students interpretations of conditional statements with multiple quantifiers, which are frequently found in mathematics texts, (2) the role of informal reasoning, including intuitive understanding and visual reasoning, and the logical decision power, in learning the mathematical ideas and constructing mathematical arguments or proofs. I believe that students' development of mathematical intuition and mathematical logic would be foundational to advance undergraduate students' successful transition to the learning of advanced mathematics ideas.
