Understanding how mathematics preservice teachers (M-PSTs) learn about issues of equity is essential to addressing the inequities that persist in mathematics education. In this article, we use (Gutiérrez, in: Herbel-Eisenmann, Choppin, Wagner, Pimm (eds) Equity in discourse for mathematics education: theories, practices, and policies, Springer,…

High school students often ask questions about the nature of infinity. When contemplating what the "largest number" is, or discussing the speed of light, students bring their own ideas about infinity and asymptotes into the conversation. These are popular ideas, but formal ideas about the nature of mathematical sets, or "set…

Reform-based discourses in mathematics education have fabricated different subjectivities for teachers such as the "traditional" and the "new" teacher. Professional development programs are proposed as effective mechanisms to fabricate the "new" teacher. However, this teacher has proved hard to produce. Thus, the…

The purpose of this study is to compare students' mathematics achievement growth rate in Texas science, technology, engineering, and mathematics (T-STEM) academies to students' mathematics achievement growth rate in traditional public high schools. Forty-six schools, 23 of which were T-STEM academies and 23 of which were matched non-STEM schools,…

This article analyzes an episode of classroom mathematics activity mediated by graphing technology from 3 different theoretical perspectives. An important line of research in the learning sciences focuses on graphs as "inscriptions", foregrounding learners' interactions with and around the material properties of graphical displays.…

Inspired by the entering of computer algebra systems (CAS) in the Danish upper secondary school mathematics program, this article addresses, from a theoretical stance, what may happen when traditional procedures are outsourced to CAS. Looking at the commands "solve" and "desolve," it is asked what happens when such CAS…

The purpose of these notes is to provide examples of large-scale geometry problems that have the potential to promote "constructive struggling" in high-school geometry classrooms. These problems are suitable for being explored in a dynamic geometry environment. The notes also contain brief sketches of solutions to the two problems.

During the past decade, the Saudi Arabian education system has undergone major changes. Government agencies involved in education have introduced new policies, standards, programs, and curricula. The focus of this research is to describe and understand high school mathematics teachers' current practices in Saudi Arabia. This research includes…

This non-experimental, descriptive study examined the effect(s), if any, that professional learning communities have had on the professional practices of secondary (grades 9-12) mathematics teachers in Boone, Clay, Putnam, and Kanawha counties in West Virginia. Also investigated were the potential differences in instructional-practice change(s)…

Functions form a central part of the U.S. mathematics curriculum. A large body of research shows that students at all levels, including preservice secondary mathematics teachers, have difficulties with defining function as a correspondence between two sets with a univalence condition. Those difficulties include privileging algebraic…

A secondary school in Melbourne, Australia piloted an innovative programme in Year 10 Advanced Mathematics, in which the students recorded screencasts as a method of student-led peer learning. The four mathematics teachers who piloted the programme were interviewed to gain their perspectives on their experience and the outcomes of the initiative.…

In the 2021 legislative session, the Tennessee General Assembly enacted Chapter 170 of the Public Acts of 2021 (PC170, now codified as T.C.A. § 49-6-1012), which requires all Tennessee local education agencies (LEAs) and public charter schools to adopt an academic acceleration policy for grades 7-12 and establish criteria for student enrollment in…

In theory, school success depends on individual merit. In practice, however, other factors beyond academic merit influence curricular placement in K-12 education. In U.S. high schools, Black and Latino students and those from low socioeconomic backgrounds have fewer opportunities to take high-level courses (e.g., Pre-Calculus and Calculus)…

While there is interest in pathways-aligned high school math reform among secondary education stakeholders, change in high school math depends a great deal on policies, practices, and norms at the higher education level. This report focuses on the role of higher education in influencing (encouraging or deterring) secondary education math reform.…

Strategies mathematics teachers use can unintentionally have an adverse impact on student anxiety in the classroom. The purpose of the Action Research study was to investigate and strengthen strategies that mathematics teachers use to reduce student anxiety. Participants and data collected in Cycle 1 consisted of interviews and a focus group with…
