Introduction
Amanda Brown’s research is largely about the study of teaching and the extent to which practice can be learned and improved incrementally with practice-based professional education. Her work inspects the ways in which particular instructional practices might make a difference for students' mathematical opportunities to learn as well as investigating pedagogical approaches that enable teachers to see and intervene in those instructional practices to improve their own teaching.

Article
In this article we examine an analytical framework generated by secondary mathematics teachers for tracking changes to their own instructional practices across time. We describe the journey of this group of teachers through professional development focused on improving instructional practice. In the midst of that experience, teachers struggled to f...
Article
Few high school students associate mathematics with playfulness. In this paper, we offer a series of lessons focused on the underlying algebraic structures of the Rubik's Cube. The Rubik's Cube offers students an interesting space to enjoy the playful side of mathematics, while appreciating mathematics otherwise lost in routine experiences.

We show how we used a national distribution of responses from 416 practicing teachers to items of a test of mathematical knowledge for teaching geometry to estimate changes in knowledge by a group of 11 practicing teachers who participated in a 2-year practice-based professional development programme. To draw a reliable interpretation of the change...
Article
We describe how a group of secondary mathematics teachers posed and solved a real-world problem. The problem was posed by teachers on a sandbar off the coast of an island in the Bahamas, where panoramic views of water meeting sky spurred the teachers to wonder how far away they could see. We analyze how the teachers translated the natural question,...

This chapter focuses on how digital technologies provide affordances for Practice-Based Mathematics Teacher Education (PBMTE) and maps needed research on technologically mediated teacher education. The chapter elaborates on Grossman’s pedagogies of practice, describing how they can be enacted in digital environments. Using LessonSketch as a prototy...
Article
Technology-mediated simulations of teaching are used increasingly to represent practice in the context of professional development interventions and assessment. Some such simulations represent students as cartoon characters. An important question in this context is whether simplified cartoon representations of students can convey similar meanings a...
Article
We contribute to the understanding of teacher noticing by focusing on what a teacher may notice in students' mathematical contributions in the context of problem‐based lessons. Complementing approaches to research on noticing that focus on individual teachers' perceptual, cognitive, or situated skills, this conceptual article offers four categories...
Conference Paper
For centuries, there has been a debate about the role of undergraduate education in society. Some have argued that universities should focus on practical skills and knowledge to prepare students for the workforce, while others have supported the idea that universities should prioritize providing a broad understanding of disciplinary knowledge and p...

Article
Full-text available
This paper contributes to understanding the work of teaching the university geometry courses that are taken by prospective secondary teachers. We ask what are the tensions that instructors need to manage as they plan and teach these courses. And we use these tensions to argue that mathematics instruction in geometry courses for secondary teachers i...
Conference Paper
Full-text available
A central goal of lesson-centered professional development programs (PD) for mathematics teachers is to learn by constructing an artifact, for example, by designing and improving a lesson plan together. That leads to the questions, what does it mean, for mathematics teachers, to improve a lesson? And how can improvements be accounted for in the ana...
Conference Paper
Full-text available
Building on student work (SW) in mathematics classroom discussion requires complex decision-making from mathematics teachers. Previous literature on problem-based lessons recommends selecting and sequencing pieces of SW in a way that creates a mathematical storyline, but there is rarely any empirical evidence on how mathematics teachers can master...
Conference Paper
Full-text available
A key characteristic of problem-based lessons in mathematics is centering students' ideas in classroom discussions. Thus, teachers need to decide which pieces of student work (SW) to share with the class. Previous studies suggest that this decision is informed by teachers' attention to the features of SW. This study focuses on this preliminary stag...
Article
To leverage pedagogies of approximation to improve teacher education, educational researchers must first tackle the methodological question, "How can we determine the potential of pedagogies of approximation for supporting the growth of prospective teachers' knowledge and practices for teaching?" In this paper, we offer a model called the Dual Acti...
Article
Full-text available
The investigation at scale of the tensions that teachers need to manage when deciding to follow recommendations for practice has been hampered by the problem of occurrence: The conditions in which those decisions could be made need to occur during an observation in order for observers to document how teachers handle them. Simulations have been reco...
Chapter
In this conceptual chapter, we illustrate how a professional-development innovation called contingency cards can be used to elicit teachers’ subject-specific pedagogical decisions in an online learning environment. Contingency cards are representations of practice that can be used by facilitators to occasion conversations about realistic contingenc...
Article
The concept of teacher noticing has been a powerful methodological tool for understanding teachers’ decision-making and professional judgment. In this line of inquiry, researchers usually try to identify elements of classroom practice salient to teachers. Data about teacher noticing and decision making can be collected at scale through the use of s...

Article
We offer a framework for analyzing teachers' practice of responding to students' mathematical contributions. This work builds on a framework developed by secondary mathematics teachers that we then augmented with one developed by linguists to create a modified framework that addresses pedagogic responding moves in detail. We show, through in-depth...
Conference Paper
Novel tasks are valuable, yet discussions of novel tasks are often challenging to manage. In this paper, we describe a U.S. high school geometry lesson taught by two teachers in six different classes, in which students were assigned a novel task that the teacher framed as an instance of two familiar instructional situations — constructing a diagram...
