Mathemalchemy: Math + Art

schedule March 21, 2025

JUNIA, Lille, FRance

Mathemalchemy is a room sized art installation that represents math through beautyand whimsy. It is currently on view at The University of Quebec in Montreal and will hopefully make a European tour starting in Fall 2027. What is Mathemalchemy? How did it come about? How did Dr. Roth get involved? Where has it been and where is going? I will answer these questions and lead a conversation about how math and art combine in the work.

Supporting all students in Calculus 1

scheduleSeptember 5, 2024

with Kristin Camenga,Juniata College Scholarship of Teaching and Learning Brown Bag Talk Series, Huntingdon, PA

Students’ skills in precalculus when they arrive in calculus have always been variable. Post pandemic there have been more missing topics. To help improve student success in calculus, we added a one hour a week co-requisite session with direct instruction in precalculus topics. It is required of students whose scores on the precalculus skills quiz assessment are lower or whose grade in the class is below 80% a B, but open to all students to attend. We will discuss the model we used and the results from the first two semesters of its implementation. Joint work with John Bukowski, Kristin Camenga, Henry Escuadro, and Jerry Kruse.

Supporting Students with Learning Gaps in MA 130 Calculus 1

scheduleFebrurary 15, 2024

with John Bukowski, Kristin Camenga, and Henry Escuadro, Juniata College Scholarship of Teaching and Learning Brown Bag Talk Series, Huntingdon, PA

Corequisite courses have increasingly become common in mathematics, especially at the college algebra level. To help students be successful in MA 130 Calculus 1, we added a 5th hour of calculus lab to the 4-credit course and administered a Precalculus assessment early enough that students can switch to Precalculus. Students prepare for the 5th hour by watching videos to work through prerequisite topics and then work in groups on problems that use the prerequisite topics in the context of Calculus. We share details of the implementation and reflect on its success in the first semester.

A Virtual Tour of Mathemalchemy

schedule August 5, 2022

with Samantha Pezzimenti, Penn State Brandywine, Math and Art Contributed Paper Session

Mathemalchemy brought together twenty-four mathematical artists and artistic mathematicians to create a large multimedia mathematical art installation, celebrating the creativity and beauty of mathematics. The project, which began in 2019 under the leadership of mathematician Ingrid Daubechies and fiber artist Dominique Ehrmann, debuted this year for its tour of exhibitions. In this talk, we will take a virtual tour of the installation, highlighting some specific vignettes, their mathematical connections, and their fabrication process. We will also discuss plans for related outreach programs, including workshops for K12 students.

Engagement in Common Reading Programs: A Five-Year Study.

schedule October 12, 2021

with Jim Tuten and Hannah Bellwoar. Conference on the First Year Experience, virtual

To explore the degree of student engagement in common reading programs, the researchers conducted a five-year longitudinal study of the common reading program at a small, private liberal arts college. Quantitative and qualitative data gathered through two surveys each year revealed rates and degrees of engagement with the program and suggested some of the range of student outcomes from a common reading program.

Seeing the Forest for the Trees: Random Forests and Predicting Fracking

schedule March 15, 2021

Allegheny Mountain Colloquium for the Allegheny Mountain section of the Mathematical Association of America, virtual

When you have thousands of variables that you can select from to describe and predict whether active fracking is occurring, how do you choose? Random forests are a learning method that uses an ensemble of decision trees to build a predictive model. We’ll discuss how to make a random forest and how we used one to tell what measures from the microbiome and the sample site best predicted active fracking status.

schedule November 01, 2018

Talk, Brown Bag SoTL Talk Series, Juniata College, Huntingdon, PA

Abstract: Classroom Response Systems also known as clickers have been used as an active learning technique together with peer instruction to increase student participation and understanding. I will discuss some study results from two recent literature reviews, one on each topic. Also I will demonstrate the free system of clickers, plickers, that I currently use.

Introduction to Data Science with No Prerequisites

schedule May 01, 2018

Electronic Poster, Electronic Conference on Teaching Statistics (ECOTS), New York City, NY

With Loren Rhodes. Abstract: Introduction to Data Science is often offered as a course with prerequisites varying from an introductory statistics course to a first course in programming. Juniata College offers Introduction to Data Science as a class with no prerequisites that is intended for first year students. The course is part of the minor in Data Science. It is team taught by a statistician and a computer scientist and uses R and Weka as computing tools. This poster will talk about the course and its content along with successes and challenges in offering the course.

Introducing R to Different Statistical Audiences.

schedule January 01, 2018

Talk, Joint Mathematics Meetings, San Diego, CA

Abstract:This semester all three of my classes, Introduction to Probability and Statistics, Introduction to Data Science, and Statistical Consulting are using R. Each class has many students who have never used R and have a few who have. I will discuss the implementations that I used in each class and what the advantages and challenges of each implementation were. Options such as using an R Studio server and different graphing tools will be discussed.

Reviewing Prerequisite Material for a Course: How and When Should It Be Done?

schedule January 25, 2017

Talk, Brown Bag SoTL Talk Series, Juniata College, Huntingdon, PA

Joint work and talk with Henry Escuadro. Abstract: When teaching a course with a prerequisite, we sometimes find that many students are underprepared on the prerequisite material needed. Whether we do a formal review or not is dependent on many factors. But if we are going to review the prerequisite material for the course we are teaching, two relevant questions that we should ask are how and when. In AY 2016, Henry Escuadro and Kim Roth worked on a project that they hoped would answer these questions in the context of Calculus 1. The standard prerequisite for Calculus 1 is Precalculus. Though Precalculus is offered at Juniata, many students taking Calculus 1 encounter the prerequisite materials in high school. However, due to various reasons, we find that many students come underprepared on precalculus material and doing a review of precalculus benefits a group of these students. Members of the Math Department do reviews two different ways — the first method is done at the beginning of the semester while the second method is done throughout the semester. This project was done to determine whether there was a difference in effectiveness between the two methods.

Plickers

schedule June 01, 2016

Talk, AP Statistics Best Practices Talks, Kansas City, MO

Plickers is a classroom response system that I use in my classroom. Slides(‘http://www.apstatsmonkey.com/StatsMonkey/ReadBestPractice_files/plickersAPReading.pdf’)

Using Plickers in Introductory Statistics

schedule January 01, 2016

Talk, Joint Mathematics Meetings, Seattle, WA

Abstract: Classroom response systems or clickers are a popular way to get whole class feedback on a question. Used with peer instruction and discussion they can enhance students understanding of the material. However many systems cost both you and the students money. Plickers is a new free option for which the students use no devices to answer the question. Instead it uses pictures based on QR codes. I will discuss the reasons clicker questions are great to use in the introductory statistics classroom and the successes and challenges of doing so with Plickers.
