### Birds of a Feather? An Exploration of the Relationships Between Equity-Orient Instruction and Inquiry-based Learning

What is Equity-Oriented Instruction? What is Inquiry-Based Learning? How are these pedagogies related? Is Inquiry-Based Learning a form of Equity-Oriented Instruction or vice-versa? Are the pedagogies’ basic tenets consistent? In this talk, I will explore these questions. Specifically, drawing on data from teaching experiments conducted in IBL-Introduction to Proof courses, Boaler’s (2002) model of the inter-relationships between knowledge, identity and practice, Pickering’s (1995) ‘dance of agency,’ Gutiérrez’s (2009) dimensions of equity, and Bourdieu’s (1984) notion of habitus, this talk explores why intentional attention towards the critical axis of equity – that which links identity and power – is necessary, if Inquiry-Based Learning pedagogies are to promote equitable learning environments.

### Edray Goins

Edray Herber Goins grew up in South Los Angeles, California.  The product of the Los Angeles Unified (LAUSD) public school system, He attended the California Institute of Technology, where he majored in mathematics and physics, and earned his doctorate in mathematics from Stanford University.

Prof. Goins spends most of his summers engaging underrepresented students in research in the mathematical sciences.  He has taught mathematics and physics in the Freshman Summer Institute (FSI) at Caltech; and led research seminars in number theory in the Summer Undergraduate Mathematical Sciences Research Institute (SUMSRI) at Miami University as well as the Mathematical Sciences Research Institute Undergraduate Program (MSRI-UP) in Berkeley, California.  He currently runs an NSF-funded Research Experience for Undergraduates (REU) titled "Pomona Research in Mathematics Experience (PRiME).”  Prof. Goins is interested in (1) Selmer groups for elliptic curves using class groups of number fields, (2) Belyi maps and Dessins d’Enfants, (3) origami as branched covers of elliptic curves, and (4) Galois groups, monodromy groups, and etale fundamental groups. He maintains his own blog about Dessins d’Enfants.

He is the president of the National Association of Mathematics, Inc which seeks to promote the success of underrepresented minorities in the mathematical sciences; and is a member of numerous advisory boards throughout the country.

### Clocks, Parking Garages, and the Solvability of the Quintic: A Friendly Introduction to Monodromy

Imagine the hands on a clock.  For every complete the minute hand makes, the seconds hand makes 60, while the hour hand only goes one twelfth of the way.   We may think of the hour hand as generating a group such that when we “move” twelve times then we get back to where we started.  This is the elementary concept of a monodromy group.

In this talk, we give a gentle introduction to a historical mathematical concept which relates calculus, linear algebra, differential equations, and group theory into one neat theory called “monodromy”.  We explore lots of real world applications, including why it’s so easy to get lost in parking garages, and present some open problems in the field.  We end the talk with a discussion of how this is all related to solving polynomial equations, such as Abel’s famous theorem on the insolubility of the quintic by radicals.

This will be a multimedia presentation.

### Carol Schumacher

Kenyon College

Carol Schumacher is Professor of Mathematics at Kenyon College and has served three terms as department chair. She received her Ph.D. in mathematics from The University of Texas at Austin.  Schumacher is the recipient of Kenyon's Trustee Teaching Award and of the Ohio Section MAA’s Distinguished Teaching Award. She is the author of Closer and Closer: Introducing Real Analysis and Chapter Zero: Fundamental Notions of Abstract Mathematics, 2E.

Schumacher is active in the Mathematical Association of America.  She was co-chair of the 2015 CUPM Curriculum Guide to Majors in the Mathematical Sciences and is MAA VP. She has addressed Project NExT fellows at their summer workshop and has been involved with workshops that help faculty incorporate inquiry into their classrooms.

### Fast forward, slow motion:  A graphical link between fast and slow time scales

The world is shaped by interactions between things that develop slowly over time and things that happen very rapidly.  Picture a garden.  A bud takes hours to open up into a flower.  A bee takes seconds to fly in, pollinate the flower and then depart.  It can be difficult to fully consider both fast and slow time scales at the same time---yet it is the interaction between these events that makes the garden work.  Mathematicians have developed a number of techniques for analyzing systems that include both fast and slow time scales.  We will consider a graphical method for predicting what happens when fast and slow interact.

### Call for Contributed Papers

You are invited to submit abstracts for the Contributed Paper Session of the Fall 2018 Section Meeting of the MAA, taking place on Saturday, October 27, 2018 at Scripps College. The talks will each be 15 minutes with a 5-minute question and transition period.

These sessions accept contributions in all areas of mathematics, including research and pedagogy, and all complete proposals will be considered. The selection of talks will be based on interest to the expected audience, on common themes with other submissions, and on scheduling constraints.

Applications to present in the contributed paper session are submitted online and are due by 12 noon on Wednesday October 10 17, 2018. Applications include submitting an abstract (max 180 words) preferably using the specified LaTex template given in the example below (downloadable tex file of sample, compiled pdf version of sample). Only the items between \begin{document} and \end{document} need to be submitted.

\title{Skeletal Shape Modeling of the Corpus Callosum: Geometry-Based Classification for Automated Schizophrenia Diagnosis}
\abstract{Diagnosing schizophrenia is currently a process of trained symptom observation and individual interpretation by doctors. The objective of this research project is to automate diagnosis by using machine learning algorithms to categorize MRI-scanned brain images as healthy or schizophrenic based entirely on shape information of the corpus callosum. We utilize a skeletal shape model called the Blum medial axis (BMA) to capture local symmetries within the boundary curves of our corpus callosum images. We then extract the most visually salient path through the BMA with a depth measure called the Extended Distance Function to (1) decompose the BMA into three subparts associated with the genu, body, and splenium of the corpus callosum, and (2) compute the curvature of a one-dimensional representation of the boundary curve of the corpus callosum. Additionally, to quantify the observed size difference of the genu, we compute Shape Tubularity, which measures the tube-like qualities of shape parts. Finally, we apply supervised and unsupervised learning techniques to these features to distinguish between healthy and schizophrenic brain images.}
