Mathematics coaching is complex work, and coaches must be supported to become experts in mathematics, mathematics instruction, and mathematics coaching. Using video and interview data from 12 mathematics coaches and one district administrator in one public school district in the southeastern USA, this qualitative study explores how the…

This qualitative exploratory case study focused on a Professional Development (PD) program for mathematics teachers in the public system, which is an underserved community of teachers in Chile. The study aimed to understand how the program addressed the challenges brought by the pandemic. Using semi-structured interviews and drawing from a…

This study proposes a model of several dimensions through which products of teachers' context-based mathematics problem posing (PP) can be modified. The dimensions are Correctness, Authenticity, Task Assortment (consisting of Mathematical Diversity, Multiple Data Representations, Question-Answer Format, Precision-Approximation, and…

We attend to the composition of even and odd functions, as featured in imagined dialogues between a teacher and students, composed by sixteen teachers in a professional development program. Data were analyzed as aimed at addressing students' intellectual needs, with particular attention to the need for causality and the need for certainty. The…

This paper describes and analyzes three cases to show the impact that curiosity-driven (CD) discourse based on self-video can have on the professional awareness and noticing skills of mathematics teachers and instructors of mathematics teachers. The findings indicate that CD discourse raises awareness of heretofore unnoticed events in the lesson,…

Catering for the mathematical needs of disabled learners equitably and productively requires the anti-ableist preparation and professional development of teachers. In CAPTeaM (Challenging Ableist Perspectives on the Teaching of Mathematics), we design tasks that emulate inclusion-related challenges from the mathematics classroom, and we engage…

The implementation of large-scale intervention and development projects is often problematic, and the impacts of such projects usually fall somewhat short of what was expected. Additionally, the rationalities of intervention projects are not carried over into classroom teaching as directly as expected. This problem is generally known, but…

Mathematics coaches are often positioned as important mediators between district administrators and teachers regarding messages about ambitious and equitable instruction. Despite this, little research has sought to unpack the connection between what coaches learn at professional development and how they make their learning available to teachers.…

Mathematical modeling (MM) -- a cyclical process that involves using mathematics to make-sense of and analyze relevant, real-world situations -- has the potential to advance equity and challenge spaces of marginalization in the elementary mathematics classroom. When informed by culturally responsive teaching practices, MM creates opportunities to…

Research on teacher questioning often provides snapshots of questioning practices or study how interventions can lead to development of questioning, but few studies have investigated if and how teacher questioning evolves naturally over time. This study explored such natural variation by analysing the questioning practice of a Norwegian elementary…

Purpose: The purpose of the study was to gather data to determine whether instructional coaching partnerships can improve teachers' implementation of learned mathematics instructional strategies. Teachers are willing to learn and implement new mathematics strategies after professional development sessions to see better student learning results.…

Background and objectives: An early understanding of numerosity is crucial to developing proficiency in arithmetic, and rapid pattern recognition via subitizing is key in this process. The training app "LORE" specifically targets and cultivates pattern recognition skills from the beginning of formal schooling. This study investigated…

We examine the effects of a year-long national-scale professional development (PD) program on mathematics instructional quality. In contrast to previous studies examining the effects of this program on instruction by comparing before and after participation or participants and non-participants, we examine whether instructional quality changed…

For educators, identifying and characterising problems in their teaching practice is essential for triggering inquiries into their practice. Knowing what educators consider problematic is essential for generating strategies for situated approaches to help teacher educators manage their problems and promote professional learning. In this study, we…

This study investigated upper elementary teachers' framings of their students' mathematical thinking in written across the three component skills of noticing. Drawing on a situated perspective, the research examines the influences of teachers' culturalhistorical backgrounds, attitudes, dispositions, interactions with students, and other situated…
