Exemplification in Multilingual Teacher Education Contexts
Friday, April 28, 2023,  12:00–1:00 PM

Abstract: Examples that teachers choose and use are fundamental to what mathematics is taught and learned, and what opportunities for learning are created in mathematics classrooms. In this presentation, I bring together three frameworks which have been used separately in mathematics education research – variation theory, meaning making as a dialogic process framework, and the notion of interacting/multifarious facets/dimensions within teacher education. The emergent framework consists of a triadic approach to understanding exemplifying practices within teacher education, and in particular, within multilingual teacher education classrooms. Lesson transcript data from an introductory class in probability in one teacher education multilingual classroom is used to illustrate how working with the amalgamated framework conduces to a powerful way of examining the choice and use of examples in mathematics teacher education multilingual classrooms, and how the three frameworks work together to attend to three critical layers involved in the complexity of teaching and learning in mathematics teacher education multilingual classrooms.

Livin' Large: Lessons Learned from the Large-Lecture Lifestyle
Wednesday, March 15, 2023,  3:30–4:30 PM
Gold Auditorium, Donald P. Shiley Bioscience Center, SDSU (Google maps link)

Abstract: After a decade of teaching in small and medium-sized class environments, I took a job as a Teaching Professor in UCSD’s Mathematics Department.  In this setting, I regularly teach large classes (80-400+ students) in both mathematics and statistics.  This talk is a reflection of what I’ve learned over the last 20 quarters and what I wish I knew on day one.  I explore the challenges and benefits of large classes, offer thoughts on aspects of pedagogy, discuss the consequences of working in large physical spaces, and think through the probabilistic realities of such courses.  This talk is not a survey of the research about large classes, but rather, an in-the-trenches reflection by someone who lives it daily.

This talk is co-sponsored by CRMSE, the College of Sciences, and the Center for Teaching and Learning.

My Scholarship of Teaching and Learning (SoTL) Journey
Friday, February 10, 2023,  12:00–1:00 PM.

Abstract: In this presentation, I talk briefly about my path to a teaching faculty position in the Applied Mathematics and Statistics AMS Department at the Colorado School of Mines (Mines), describe the teaching faculty position and the supportive culture around teaching at Mines, and discuss three recent SoTL projects. The Colorado School of Mines is a medium-sized public R1 research university located in Golden, Colorado that is focused on science and engineering. Every undergraduate student at Mines takes the three-course calculus sequence (I, II, and III) and ordinary differential equations as required courses.

The SoTL projects that I describe in this talk include: (1) a team-based approach to developing a partially flipped linear algebra class; (2) a calculus II course redesign and supporting faculty through pedagogical change; and (3) a study of course coordination in the AMS department. The first two projects on linear algebra and calculus II have resulted in PRIMUS (Problems, Resources, and Issues in Undergraduate Studies) publications, and the third project on coordination is still in progress.

Design research in the context of pre-service teacher education: Which design principles can be fruitful for relating Abstract Algebra and School Algebra and what do the learning processes look like?
Friday, December 2, 2022,  12:00–1:00 PM.

Abstract: Pre-service teachers often see little to no relevance in their mathematical content courses for their future mathematics teaching. Looking at the situation in Germany, content courses often get poor evaluations and students drop out from mathematics teachers’ programs especially for high school level.

In order to make mathematics teaching more meaningful for students, course designers currently put huge development efforts in their teaching designs and suggest “bridging courses” or “bridging tasks” for making more explicit how abstract university mathematics relates to the future mathematics teaching. So far, however, the thereby initiated learning processes are still highly under-researched.

This is why we draw on a topic-specific design research approach and apply a framework of “knowledge reshaping” for also taking into account the initiated learning processes. In the talk, I will show how we formulated our design principles and give insights into the teaching material which was tested in laboratory design experiments with future teachers in their master’s program. First results of in-depth analyses of the learning processes will be presented and discussed.

Integrating Measurement, Cognition, and Curriculum Design to Enable Meaningful and Equitable Biological Learning
Friday, October 28, 2022,  12:00–1:00 PM.


Undergraduate biology education needs to change if we are going to improve learning outcomes, meet the needs of diverse learners, and inspire a future generation of scientists that are representative of the nation. Achieving this change requires the integration of measurement, cognition, curriculum design, and equity-aligned frameworks. In this talk, I provide an overview of my work on biology thinking and learning and discuss how I leverage this work to improve outcomes in gateway biology.

The Use of Ethnomathematical Activities and Approaches in the Teaching and Learning of Mathematics
Monday, October 3, 2022,  3:00–4:00 PM.


Research on Ethnomathematics and its use in the teaching and learning of mathematics has been conducted over the past 40 years. The results of many of these studies indicate that students (learners) in mathematics classrooms find the use of ethnomathematical approaches helpful in the understanding of various mathematics concepts. Some of the results of the studies indicate that even though there is increasing evidence of the usefulness and importance of ethnomathematical activities and approaches, some of the teachers are struggling to integrate such approaches in their classroom practices. This talk covers the following:

  1. The work of Ethnomathematicians and Mathematics Educators who have done work in ethnomathematics such as Ubiratan D’Ambrosio, Paulus Gerdes, Alan Bishop, Bill Barton, Marcelo Borba, Gelsa Knijnik, Arthur Powell, Joanna Masingila, Claudia Zaslavsky, etc.
  2. Examples of ethnomathematical activities (including indigenous games) that may be used in the teaching and learning of mathematics with illustrations from mathematics classrooms in South Africa.

Exploring Secondary Mathematical Knowledge for Teaching through Student Work
Friday, April 8, 2022,  12:00 Noon-1:00 PM.

Abstract: A teacher’s mathematical knowledge for teaching (MKT) has been shown to be a significant factor in predicting student outcomes and positively related to the quality of mathematics instruction. Yet researchers have almost exclusively focused on elementary teachers’ MKT, leaving very little understanding of MKT for secondary teachers. In this talk, Dr. Zimmerman will present her findings from an exploratory, multi-case design study that investigated the realms of knowledge used by expert mathematics educators when engaging with student quadratic function work. Findings from the study specifically address the nature of secondary MKT for teaching quadratics while study approaches address engagement with student written work and the needed assimilation of MKT research to advance secondary MKT understanding.

Characterizing Student Engagement in a Post-Secondary Developmental Mathematics Class and Exploring the Reflexivity between Social and Socio-mathematical Norms
Friday, February 18, 2022,  12:00 Noon-1:00 PM.

Abstract: Traditionally, post-secondary developmental mathematics courses have strived to equip students with mathematical content knowledge needed to succeed in subsequent STEM courses. However, it is critical that such emphasis be coupled with deliberate attention to developing higher-order skills such as argumentation, reasoning, and flexibility in mathematics problem-solving. In this talk, I will share some of the findings of my mixed-methods dissertation project that incorporated a semester-long teaching experiment which aimed to support students' development of higher-order skills by utilizing instructional interventions to facilitate more productive mathematical engagement. Engagement was then characterized by the classroom norms that evolved over the course of the semester. Results show that deliberate attention towards negotiating productive classroom norms and students' in-class engagement can positively affect students' attitudes towards flexible knowledge in mathematics problem solving. This project also highlights the perpetuation of students' beliefs (some of which were unproductive) and their influence on the development of classroom norms. The talk will illustrate this study's contribution to furthering the theoretical relationships between classroom norms, and make suggestions for the practice of teaching developmental mathematics courses.

What Does it Mean to be Smart in Math Classrooms? From the Perspective of Black Learners
Friday, November 12, 2021,  11:00 AM-12:00 Noon

Abstract: The talk addresses the question “How do Black learners describe what it means to be smart in a summer mathematics program." The study is a multi-case study of 5 fifth-grade Black learners. In the talk I describe both the different conceptions learners had as well as the complexity of those conceptions. Implications of these work include methodological considerations for capturing student’s conceptions (epistemology) and the heterogeneity within studying Black learners.

Charles Wilkes is a postdoctoral researcher at CRMSE working on the Math Persistence through Inquiry and Equity (MPIE) project. His work focuses on the experiences of Black learners in mathematics and equitable teaching practices. Specifically, his work has focused on Black learners’ conceptions of smartness, how Black learners are positioned in mathematics courses, and how teachers signal messages about smartness through their practice.
