Teaching & Mentoring

The best way to learn is to teach. – Frank Oppenheimer

I have a combined ten years of experience teaching and mentoring students in mathematics and mathematics education courses from secondary school to graduate level. In my practice of teaching, I foster participation in learning through discussion, argumentation, and problem solving—you learn mathematics by doing mathematics. I innovate by implementing research-based practices including sequencing learning goals and instruction with multiple technology-based representations—meaningful understanding of mathematics is connected.

Statement of Teaching Practice

Teaching mathematics is a craft and art form.

My practice of teaching mathematics weaves together innovative thinking that is informed by research and theory on student learning, and effective design of curriculum and instruction. My goal as a teacher is to provide opportunities that challenge yet support students as they grow in their own quests, and to negotiate productive norms within the classroom community.

I never teach my pupils. I only attempt to provide the conditions in which they can learn.

Engagement Through Discussion and Problem Solving

I hold high expectations of my students and build my classes around student engagement, with a requirement for active participation and discussion. My role in the classroom is to both facilitate students’ knowledge acquisition and construction, and to lead the direction of the course as an expert participant, modeling the processes of learning mathematics through argumentation and logic.

For example, in a geometry course for preservice teachers I positioned the students as problem solvers and arguers. They learned to become confident in their mathematical reasoning because mathematical authority was not positioned solely in the textbook or the instructor, but rather on their own clear argumentation and logic. During a heated discussion on classification and definition, the students reached an impasse. When I prompted, “What are we going to do?” one student raised a fist and declared, “We’re gonna’ fight!” After laughter ensued, students led a debate to resolve their issue. This example shows how I push students to explain their thinking, respond to the thinking of others, and engage in mathematical argumentation.

I seek balance in discussion-focused classes by incorporating student-led problem solving in individual, small group, and whole-class settings. The effectiveness of these instructional techniques rests on students’ motivation to engage during class, and their willingness to learn in an environment where multiple perspectives are encouraged and valued. Effective communication is paramount to learning mathematics and mathematics education research, and beyond.

My undergraduate students have reflected, “I’ve never had to talk and write in a math classes before.” My graduate students have welcomed discussion-oriented classes. I support multiple formats of instruction, and encourage students to experiment with their own styles of teaching by leading class sessions themselves.

Linking Research and Practice

My research and teaching are linked both in how I support student learning and how I assess and characterize student learning. I support student learning of mathematics by sequencing learning objectives and multiple representations in ways that have been shown to be effective in empirical research.

For example, in teaching equation solving it is important to understand the equal sign as an equivalence relation. One approach is to first support students’ understanding of equivalent and non-equivalent expressions from multiple representations, and to link this understanding to the meaning of the equal sign as a relationship between expressions.

In learning symbolic algebra, I encourage students to be strategic about the use of technology.The following example shows how reconciling is an effective practice for leveraging technology as a learning tool, not as a crutch.

One algebra student incorrectly applied the distributive property with paper-and-pencil. When he reflected on the outcome of using a computer algebra system, he realized “I needed to multiply it [the coefficient] all the way through [instead of the first term only].” (Source: Fonger (2014).

Finally, in assessing learning, the meaning a student holds of a representation is connected to their conceptions. It is important to probe the meaning of students’ use of representations as both a formative tool to guide instruction and as summative measures of meaningful understandings.

For example, A=aL2 may represent a correspondence rule between length (L) and area (A) of a growing square, or a statement of covariation as length and area change together.

As an educator and lifelong learner, I understand the importance of motivating students to take ownership of learning, and the power of research-based curriculum, instruction, and assessment. I excel when teaching in novel contexts because I approach teaching as an opportunity to experiment with research-based curriculum and instruction—cycles of design, implementation, and analysis builds theory.


Teaching Experience
