The purpose of this study was to understand how and why middle grades mathematics teachers did or did not fully participate in sustained, content-focused professional development. Qualitative data were collected from middle grades teachers who demonstrated varying levels of participation. The teachers identified opportunities to engage in novel…

Central in the frameworks that describe algebra from K-12 is the idea that algebraic thinking is not a single construct, but consists of several algebraic thinking strands. Validation studies exploring this idea are relatively scarce. This study used structural equation modeling techniques to analyze data of middle school students' performance on…

Visualising positive and negative numbers on a number line is helpful for exploring problems involving operations with positive and negative numbers. This is because number lines lend themselves to exploring problems involving continuous linear contexts such as travelling distances and temperature. Teachers in a professional development program…

As the field draws to greater consensus around components of productive mathematics classrooms, the need increases to answer questions about how we operationalize and measure these components and how we can actualize such practice in classrooms. This research report shares an analysis from a larger project aimed at describing and quantifying…

Middle school students who need help understanding how to manipulate math expressions involving the negative sign have demonstrated difficulty learning pre-algebra content that prepares them for higher-level math courses. This study involved a multimedia intervention to improve student negative sign proficiency and math self-efficacy. The…

This brief research report examines the discursive shifts of a secondary mathematics teacher participating in a collaborative learning community centered on culturally responsive mathematics teaching. We draw on two frameworks to analyze the teacher's discursive moves. The first framework comes from Lefstein et al. (2020) on generative discourse…

As procedural flexibility, previously understood as adaptive reasoning, emerges as an important consideration in math skill development, it is important to account for executive functioning in that process as well, as executive functioning a well-researched factor in math performance. The current study, a secondary data analysis, explores how…

This study aims to develop multiple intelligence-based textbooks seventh grade junior high school students with material on equations and inequalities. It is hoped that the results of the development of this textbook can improve student learning outcomes, especially in the ability of mathematical representation. The population used was students of…

Theories of gender and race in mathematics education predominately remain unchanged in recent years (Damarin, 2008; Parks & Schmeichel, 2012), with feminism not always seen as relevant to mathematics education. New theories and methodologies related to gender create possibilities to reinvigorate gender research in mathematics education and…

Purpose: This study aimed to explore teachers' learning processes through a hybrid cross-cultural lesson study (LS) because little is known about the learning process through this novel and promising LS approach. Design/methodology/approach: This cross-cultural LS lasted over six months focusing on developing a research lesson (RL) related to…

In this study, we highlight the differences in classroom-, teacher-, and school-level factors in 8th and 9th grade algebra experiences along socioeconomic and racial/ethnic lines using nationally representative survey data from the American Mathematics Educator Study. Several takeaways emerge from our analysis. First, we show that highest-poverty…

Motivating students in mathematics requires innovative and engaging approaches. This Spotlight explores strategies to foster a love of math and cultivate students' problem-solving abilities. From creating motivating classroom environments to connecting math to potential careers, these articles offer valuable perspectives. Discover how to build on…

This study, which is part of a larger project that aims to make online math more accessible to students with visual impairments (VI), examines the text quality of math assessment items for students with VI who use screen readers. Using data from about 29.5 million students taking standard versions of the MAP Growth math assessment, and 48,845…

The purpose of this mixed method nested case study is to: (a) provide indicators and experiences math educators have recognizing math anxiety in students; (b) identify ways in which middle and high school math educators implement creative teaching strategies to reduce math anxiety in middle and high school students; and (c) look at the veracity…

As mathematical patterns become more complex, students' conditional reasoning skills need to be nurtured so that students continue to critique, construct, and persevere in making sense of these complexities. This article describes a mathematical task designed around the online version of the game Mastermind to safely foster conditional reasoning.
