Friday night public lecture: April 12th at 8:00pm in Buckley Center Auditorium [Updated 4/9]

How do mathematicians believe?
Brian Katz, Augustana College.

Love it or hate it, many people believe that mathematics gives humans access to a kind of truth that is more absolute and universal than other disciplines. If this claim is true, we must ask: what makes the origins and processes of mathematics special and how can our messy, biological brains connect to the absolute? If the claim is false, then what becomes of truth in mathematics? In this session we welcome educators and students to discuss our beliefs about truth and how they play out in the mathematics classroom, trying to understand a little about identity, authority, and our joint educational endeavor.


Saturday morning lecture: April 13th at 9am in Buckley Center Auditorium

Writing Numbers as the Sum of Factorials
Su Doree, Augsburg College.

In standard decimal notation, we write each integer as the linear combination of powers of 10. In binary, we use powers of 2. What if we used factorials instead of exponentials? How can we express each integer as the sum of factorials in a minimal way? This talk will explore the factorial representation of integers, including historical connections to permutations, a fast algorithm for conversion, and the secret of the “third proof by mathematical induction.” Next we’ll extend this representation to rational and then real numbers, ending with some remaining open questions.

Saturday afternoon lecture: Bauccio Commons (Bluff Side) at 2pm 

The role of models of contagion: its impact in building interdisciplinary communities of undergraduates over 24 years
Carlos Castillo-Chavez, Arizona State University.

In 1996, the Mathematical and Theoretical Biology Institute or MTBI was established at Cornell University. The goal was to bring undergraduates from diverse backgrounds into the field of mathematics and its applications, particularly within computational, mathematical and theoretical biology.

In this lecture, I will discuss how MTBI ( was established and how it has evolved over the past 24 years. The role that MTBI has played in the development of nearly 160 PhDs and its impact on increased opportunities among underrepresented groups will also be highlighted. Finally, the extraordinary research generated by undergraduate participants over a few weeks, all available at

Saturday evening lecture: Bauccio Commons (Bluff Side) at 6:45 pm. [Updated 4/9]

Role of social dynamics and individual decisions on the spread of infectious disease
Carlos Castillo-Chavez, Arizona State University.

I will revisit the field classical mathematical epidemiology starting from the contributions of Sir Ronald Ross in 1911. Extensions of Ross’ framework and recent applications will be discussed in the context of the study of the spread of diseases that include social dynamics. Emphasis will be placed on the role of individual decisions, in changing socio-epidemiological landscapes and the control of epidemic outbreaks. Examples will be provided from communicable diseases under scenarios that account for various modes of transmission.


Minicourses Friday 3:00-5:30

Turning Routine Exercises into Activities that Teach Mathematical Inquiry
Sue Doree, Augsburg College

Asking questions, checking examples, making conjectures, and constructing counterexamples are part of any mathematician's toolkit and important skills for our students to learn. The MAA CUPM curriculum guide agrees, calling us to ``include activities designed to promote student's progress in learning to . . . assess the correctness of solutions, create and explore examples, carry out mathematical experiments, and devise and test conjectures'' with the goal that ``students should develop mathematical independence and experience open-ended inquiry.'' How do we help students develop inquiry skills and ignite their curiosity about mathematics? In this professional development workshop we explore some practical strategies you can use to transform routine textbook exercises emphasizing procedural fluency and basic conceptual understanding into activities that teach inquiry. Come ready to try your hand at creating inquiry-based activities.

Author Your Next Book (or Class Notes) with PreTeXt
Rob Beezer, University of Puget Sound

PreTeXt is a new source language for authoring scholarly documents, with excellent support for mathematics and textbooks. Its principal advantage is conversion to print and PDF formats, along with conversions to highly interactive online formats, all requiring no additional effort for each output format. It is an ideal platform for authoring an open source textbook that will be freely available.

This workshop will very briefly introduce the design philosophy of PreTeXt, and then work through a hands-on exercise creating a small example document in multiple output formats. Remaining time will be used to start on a small project of your choosing.

Special Sessions, Contributed Papers, and Student Presentations

Abstracts for all presentations are due March 15th. Please use the LaTeX template (a Word document or .pdf that contains the name and affiliations(s) of the presenter and author(s), talk title, and a short abstract is acceptable, but will be re-formatted). Please submit your abstract via e-mail to and cc the Special Session organizer if you are presenting in one of the sessions below. If you are a student please be sure to state so in your submission e-mail; you will get a discount code for registration!

In addition to the special sessions, below, there will be a several sessions devoted to student talks and a contributed paper session. In fact, half of the general program at past meetings over the last decade has been comprised of student talks; we encourage students to talk about their MCM solutions, senior thesis or capstone project, REU or other work!

The following Special Sessions are being organized for the meeting. Please contact the organizer if you are interested in being invited to present.

Algebra and Number Theory, Thomas McKenzie (Gonzaga)

The organizer welcomes any talks on the subject of pure or applied Algebra or Number Theory.

Algebra and Topology, Kate Kearney/Kat Shultis (Gonzaga)

This session will be devoted to talks on research in Algebra and Topology. We welcome all branches of Algebra and Topology, but particularly encourage talks that have relevance to both disciplines.

Topics in Undergraduate Mathematics Education, Elise Lockwood (Oregon State)

We welcome presentations that share findings related to the teaching and learning of mathematics at the postsecondary level. These presentations could be research-based (including reports of qualitative or quantitative empirical studies and theoretical discussions), or they could focus on pedagogical and curricular innovations that have been tested in the classroom. We are open to a wide range of topics, including but not limited to: the teaching and learning of particular mathematical concepts, teaching at the undergraduate level, student cognition, and effective classroom interventions.

Aligning practice and assessment with course learning goals, Craig Gin, Kelsey Marcinko, Jeremy Upsal (UW)

Assigned practice and assessment are two major themes of any mathematics course. One way to facilitate accurate assessment of student learning and knowledge is to better align assessment with both assigned practice and a set of established course learning goals. This is further facilitated by considering students’ level of learning according to Bloom’s taxonomy of educational objectives for knowledge-based learning goals. As instructors, we would all benefit from more examples of well-aligned assessment strategies with explicit course goals or knowledge level. We welcome presentations discussing ideas, noted difficulties, or examples with the hope of encouraging conversation to improve students’ learning.

Conversations About Equity in Mathematics, Ksenija Simic-Muller (PLU), Ekaterina Yurasovskaya (SU)

Our session provides a platform for ongoing conversation about issues of equity in mathematics, math education, and related institutional structures – and their subsequent effect both on society and on lives of particular students. We want to hear many voices; topics can reflect a variety of experiences involving race, gender, age, immigrant status, income level, and their intersections in the context of math and math education.

We particularly encourage students to submit talk proposals. If you are working within your university, preparing for a career as an educator, or participating in community work, and would like to share your equity-related field experiences and concerns, we would love to hear from you! Other topics illustrating interplay of mathematics, equity, and society are equally welcome. The session will consist of several presentations and will conclude with a discussion.

Incorporating Data Science in the Undergraduate Curriculum, Xiaoyue Luo (Linfield)

Data science is quickly becoming one of the most in-demand disciplines. Many universities and colleges now have programs dedicated to data science education. This session invites presentations to showcase where data science topics can be incorporated to mathematics courses and programs, such as data science majors, minors, tracks, certificates, online pro- grams, summer programs and boot camps. We encourage presentations on curriculum plans, external resources, internship opportunities and job connections. We seek presentations on designing courses and programs for students with different interests and backgrounds.

Saturday Social and Hors d'Oeuvres

A social hour with no-host bar and hors d'ouevres in the Bauccio Board Room (or outdoors, weather permitting) followed by section awards ceremony and evening address. ID is required for those who are 21 and older wish to purchase and consume alcohol.
