The COVID-19 pandemic prompted schools to transition to remote instruction during the latter half of the 2019-20 school year and continuing into the 2020-21 school year. National Assessment of Educational Progress (NAEP) data trends indicate that there were statistically significant declines in students' mathematics and reading scores between 2020…

Purpose: The purpose of the study was to evaluate the implementation and impact of the IDEA Public Schools' Mathematics Curriculum Redesign (MCR) effort, funded by an Innovation and Research (EIR) grant. Methods: The study used a quasi-experimental matching design to examine the effect of MCR on student achievement outcomes. The study compared…

This article from Carly Sawatzki and Peter Sullivan encourages schools and teachers to consider ways to embed financial literacy tasks in mathematics lessons more often, and includes an authentic task to try with your students.

Mathematical inquiry is an approach whereby students respond to ill-structured, open-ended questions that reflect the authentic problems we encounter in 'real' life (Allmond, Wells & Makar, 2010). An open-ended ill-structured question has no single correct answer and often contains ambiguities in the problem that require students to make a…

We present noncompetitive adsorption as "particles in a box with one sticky wall." We start with a general model that can be modeled as a simple ordinary differential equation (ODE). To verify the ODE students run a computer simulation. The ODE's solution imperfectly fits the simulation's data. This leads to the diffusion partial…

The Corvette Problem is a nonroutine investigation, one that provides an authentic context to explore many interrelated calculus ideas. In our years of sharing this problem with students and colleagues, we have found additional topics from the calculus curriculum to have rich interpretations in this environment. The Corvette Problem contextualizes…

L.V. Zankov (1901-1977), a student and colleague of Vygotsky, developed a system of developmental education for elementary education through 20 years of extensive research. Since 2009, a number of Norwegian schools have been using textbooks in mathematics based on Zankov's system. In this article, we present and discuss the experiences of some…

In mathematics, there are countless connections between apparently unrelated topics. Students often find these relationships interesting, and they contribute to expanding their mathematical repertoires. This article describes one of these unusual connections, between the sum of periodic functions and the commensurable and incommensurable numbers.…

The aim of the study is to reveal the preservice mathematics teachers' ability to determine the techniques of proofs on integers. A qualitative case study approach was adopted in this study. The participants of the study consisted of 172 preservice teachers enrolled in an elementary mathematics teaching program in their second and third years at a…

In the United States (US) and elsewhere across the world, undergraduate mathematics instructors are increasingly aware of the value of inquiry-based instruction. In this research commentary, we describe the intellectual origins and development of two major strands of inquiry in US higher education, offer an explanation for apparent differences in…

Middle school students are faced with a number of mathematical concepts that require new forms of reasoning. Although the shifts toward proportional and algebraic reasoning are often emphasized in middle school curricula, changes in the nature of geometric reasoning are not always given the same weight. As highlighted in "Catalyzing Change in…

A small percent of high school students are performing above satisfactory on end-of-course assessments, especially in Algebra 1 and Geometry. This is indicative that mathematics instruction may need to improve. One innovation in mathematics instruction is the incorporation of storying as an instructional strategy, as there is considerable research…

This article investigates perceived existing classroom practices in mathematics pedagogy and the impact on Nepalese mathematics teachers' understanding and uses of questioning. For this study, a narrative inquiry approach has been used to focus on the experiences of six mathematics teachers working in schools in Kathmandu Valley, Nepal. A…

Undergraduate mathematics education can be experienced in discouraging and marginalizing ways among Black students, Latin* students, and white women. Precalculus and calculus courses, in particular, operate as gatekeepers that contribute to racialized and gendered attrition in persistence with mathematics coursework and pursuits in STEM (science,…

American colleges are redesigning the ways in which they offer remedial courses, including mainstreaming students into college-level courses and making greater use of learning-technology to tailor the curriculum to students' specific academic needs. Exploiting a statewide cutoff on a remediation placement exam along with data on student outcomes…
