I am a mathematics professor at Sinclair Community College in Dayton, Ohio. I have taught a variety of courses ranging from developmental math through pre-calculus. I am a past recipient of the Roueche Award for teaching excellence. I am also a past recipient of the Ohio Magazine Award for excellence in education.

I have published in several peer-reviewed journals. My articles have focused on implementing best practices in developmental math and various math pathways for community college students. Additionally, I was the recipient of the Article of the Year Award for my article, “Acceleration and Compression in Developmental Mathematics: Faculty Viewpoints” in the Journal of Developmental Education. My first book, "Breaking Barriers: Student Success in Community College Mathematics" focuses on students' endeavors through community college math through their eventual success in a college-level math course. My second book, "Community College Mathematics: Past, Present, and Future" examines the trends, initiatives, and mandates throughout the rich history of community college math. Moreover, I address how we can help students sustain success in math in the future by learning from the past and present.

My research focuses on all aspects of mathematics teaching and learning with Latinas/os through the framework of mathematics and language socialization processes, or Mathematics Discourse Communities. My current studies aim to understand 1) the struggles and successes of monolingual teachers of bilingual, Latina/o students as they plan, implement and reflect on lessons, and 2) how we might develop and incorporate curricular features that provide bilingual learners better access to mathematical ideas and more opportunities to engage meaningfully, as well as provide a model for teachers to develop a critical pedagogy with bilingual learners.

Dr. Melissa A. Gallagher focuses on supporting teachers to develop the knowledge, beliefs, and practices necessary to support the mathematical potential of all students, especially multilingual learners. In order to support teachers in this goal, we also study the ways in which culturally and linguistically diverse students express their mathematical ideas. We value diversity of thought, culture, and language, and see multilingualism and multiculturalism as critical to innovation. We work in partnership with teachers, students, and parents to help all students reach their full potential in mathematics.

Title: From Mathematical Play to Playful Math
Abstract: Mathematical play offers opportunities for students to exercise agency and engage in authentic disciplinary practices, and studies of mathematical play show positive outcomes for motivation, enjoyment, and learning. However, the current research base is largely situated either in early childhood / elementary school, or in informal settings such as video games or makerspaces. These studies investigate how play can be mathematized, examining the mathematics that arises from play. I consider the reverse direction, that of "playifying" the school mathematics that students and teachers must navigate in classroom contexts. In doing so, I'll share findings about mathematicians', undergraduates', and middle-school students' playful math engagement. Our study found that playful math tasks increased students' agency, authority, investment, and goal selection, as well as encouraged their development of creative, challenging ideas. I'll present two cases of a particular form of playful engagement called the "explore - focus cycle", one for a mathematician and one for a pair of middle-school students, and consider how playful math can support students' disciplinary engagement.

​Title: From What about the 2SLGBTQIA+ folx? Toward A Truly Equitable Mathematics
Abstract: In this interactive talk, we will briefly explore the relationship between mathematics teaching and learning and 2SLGBTQIA+ identity, then consider a framework, the Mathematical Queeries Framework (MQF) that centers on 2SLGBTQIA+ equity in mathematics education. Participants will also engage with a mathematics activity that embodies many elements of the framework in action

Title: Building Racial Justice in Mathematics Education: Against Asian American Invisibility and Hypervisibility

Abstract: Everyone seems to be talking about racial equity and justice these days. Increasingly, scholars in mathematics education are recognizing the need to center the voices of those most affected—i.e., Black, Latine, Asian, and Indigenous children and families—in these discussions. Our current project explores participatory design research (PDR) as a tool for building school, university, student, and parent capacity for centering children of color and their families as researchers and designers of middle school mathematics learning, in a small but diverse Midwestern city. In this talk, we will discuss Asian American and particularly Hmong invisibility and hypervisibility as challenges to working for racial justice. We will share how these phenomena are affecting our project and outline our current efforts to make ourselves and the students of color we are working with visible in our full humanity.

Dr. Elizabeth van Es headshot



Dr. van Es is interested in teacher thinking and learning and the design of pre-service teacher education and professional development. Her research is primarily concerned with how to support teachers' developing their noticing practices for ambitious and responsive instructional practice. Much of her work uses video to help teachers develop a vision of ambitious instructional practice and to learn to attend to student thinking during instruction. She has recently expanded her research to examine teachers' noticing for equity, focusing on how teachers' commitments to equity inform their noticing and instructional practice. She is launching a new study with the support from the National Science Foundation to develop a model of professional development that brings together secondary mathematics teachers, youth, and community leaders to advance teachers' noticing for equity in teaching. In addition, building on her research on pre-service teacher education, she received funding from the University of California Office of the President with colleagues at various University of California campuses to develop a data base that will study the influence of pre-service teacher preparation on beginning teaching practice. This study will take an improvement science approach to develop measures for assessing pre-service teacher effectiveness. From her online profile
