Context Matters: How Beliefs Impact Reasoning About Calculus and Proofs Ms. Caroline Merighi Tufts University PhD Student “We will look at calculus students' beliefs about mathematics and how those beliefs impact the ways they reason about graphs of functions. We... Read More
Visualizing the Gromov Boundary Mr. Daniel Gulbrandsen University of Wisconsin-Milwaukee PhD Graduate Student – Teaching Assistant “We will begin with some background of geometric group theory, including notions of quasi-isometry and delta-hyperbolicity. Then, we will define the Gromov boundary and... Read More
