Heather Bolles is a member of the Department of Mathematics. She completed a B.S. in mathematics with secondary certification from ISU and a PhD in mathematics from ISU while working under B. Keller, a former director of the MSM program. With an interest in developing students' conceptual understanding of mathematics, Dr. Bolles has written and implemented experientially based explorations in calculus courses and in courses for elementary and secondary pre-service teachers. Previous research has emphasized the development of the inquiry process in mathematics classrooms and the relationship between this process and the concepts which resonate in students. She is interested in developing and applying methods to actively engage students in the learning of mathematics, to build understanding of the underlying concepts of mathematics, to incorporate technology appropriately in the teaching and learning of mathematics, and to establish connections within mathematics, between mathematics and other subject areas, and with prior knowledge.
