Title: On the Radon Transform
Abstract: In this talk we will introduce, motivate and discuss some of the elementary properties of the Radon transform operator. We will cover a little about how to invert this operator via its adjoint (i.e. back-projection operator) and approximate identities.
Speaker: David Webb (Associate Professor of Mathematics Education Executive Director, Freudenthal Institute US University of Colorado Boulder School of Education)
Title: Infusing Active Learning Design Principles in the Undergraduate Calculus Sequence
Abstract: This interactive presentation will provide a brief overview of undergraduate mathematics at the University of Colorado Boulder, and related activities that we and other universities have designed and used in the freshman pre-calculus through Calculus 2 sequence. Using principles of Active Learning, students are encouraged to conjecture, explore and communicate their reasoning in the process of solving mathematics problems. Underlying this approach is research that has demonstrated how students who are involved in active learning techniques can learn more effectively in their classes, resulting in lower DFW rates, increased persistence in subsequent courses, and improved dispositions towards mathematics.
