Decomposing and Scaffolding the Introduction to Proof

Wednesday, October 5th from 3:20 to 4:15pm
UNA 125

Decomposition of practice can be described as the breaking down of a complex practice into its constituent parts. Mathematical practices, such as proving and mathematical modeling, tend to be complex and in need of productive decompositions. Decompositions are necessary if we are to make progress in teaching important disciplinary practices and sustaining the call to have students’ classroom experiences in each subject more closely resemble their respective disciplines. Through this colloquium, I will provide insights into the work of teachers in practice, specifically some of the conditions, challenges, and issues related to teaching proof at the secondary level. In addition, potential solutions for addressing these challenges will be presented through data and findings from the three-year research project. These findings have implications for teaching reasoning that leads to proof at the middle school level and for teaching proof at the post-secondary level.

Dr. Michelle Cirillo received her PhD from Iowa State University in 2008 after working as a high school mathematics teacher in NY for 8 years. Cirillo’s primary research interests include the teaching of disciplinary practices (e.g., mathematical proof and modeling), classroom discourse, and teachers’ use of curriculum materials. She is especially interested in the space where these three areas intersect. As a co-PI on a five-year NSF Discovery Research K-12 grant, Cirillo has been working with researchers from Michigan State University to design and pilot professional development materials to support secondary mathematics teachers’ facilitation of classroom discourse. In 2010, Cirillo was awarded a research fellowship from the Knowles Science Teaching Foundation to pursue a three-year study on the teaching of proof in high school geometry. She is currently the PI of an NSF-CAREER grant, which builds on the Knowles project. Cirillo was the lead author on the article, Developing curriculum vision and coherence: Adapting curriculum to focus on authentic mathematics, which won a National Council of Teachers of Mathematics Research and Practice Outstanding Publication Award in 2010.

West Chester University Computational Sciences and Applied Mathematics Seminar

Location: UNA 125

Title: Parallel computing of solving Poisson-Boltzmann equation and calculating corresponding electrostatics for large macromolecules and complexes

Abstract:

One common approach to study electrostatics in molecular biology is via numerically solving the Poisson-Boltzmann equation (PBE) and calculating the electrostatic potential and energies. However, all existing numerical methods for solving the PBE become intolerably slow when solving the PBE for large macromolecules and complexes consisting of hundreds of thousands of charged atoms due to high computational cost. Parallel computing is a cutting-edge technique which teams up multiple computing units and significantly speeds up the calculation. In this talk, I will present a set of parallel computing algorithms developed to solve the PBE. As a demonstration of efficiency and capability of these algorithms, computational results obtained by implementing these algorithms in the DelPhi software http://compbio.clemson.edu/delphi on live large macromolecules and complexes are given as well.

Title: The Extended Parareal Algorithm for Time-and-Space Parallel Computing of the Cable Equation

Abstract:

The Parareal Algorithm introduced by Jacques-Louis Lions, Yvon Maday, and Gabriel Turinici is an efficient method for achieving parallel computing in time direction for solving time-dependent partial differential equations. However, we have not seen in literature a method to effectively incorporate the spatial-parallelized schemes into the framework of the Parareal algorithm in order to obtain both temporal and spatial parallel computing. In this work, we present a work to extend the original Parareal algorithm to effectively embrace spatial-parallelized solvers to accomplish time-and-space parallel computing of the Cable equation on long cardiac tissues.
