Math performance continues to be an important focus for improvement. The most recent National Report Card in the U.S. suggested student math scores declined in the past two years possibly due to COVID-19 pandemic and related school closures. We report on the implementation of a math homework program that leverages AI-based one-to-one technology,…

We discuss the importance of bringing teaching to the forefront of instructional design. We do so by describing the process of developing an instructional sequence for early number, using design research. The instructional sequence was developed with the specific aim of supporting teaching, conceived as a complex and demanding job, not reducible…

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…

The Numeracy Kit for Kindergarten 5-Year-Olds (NyKK-5) is a tool to support kindergarten teachers' numeracy practices. Based on a pedagogy of enactment, the NyKK-5 was designed to simulate the types of in-class supports that have been identified as critical elements of effective mathematics professional development (PD). Two groups of teachers…

We report on an effort to vet a list of 10 student learning objectives (SLOs) for geometry courses taken by prospective geometry teachers. Members of a faculty online learning community, including mathematicians and mathematics educators who teach college geometry courses taken by prospective secondary teachers developed this list in an effort to…

The purpose of this study was to help undergraduate STEM students at a Hispanic-serving institution make connections between calculus and physics content and their lives using a utility-value intervention. As part of either a Calculus II or a calculus-based Newtonian Physics course, 471 undergraduate students were randomly assigned to either read…

This study investigates geometry teachers' evaluations of problems that use visual arts contexts. We ask, "how do teachers' evaluations relate to the four arguments justifying the geometry course?" and "How do teachers draw on the APPRAISAL system to evaluate sample geometry problems from textbooks?" Nine high school teachers…

In this pedagogical action research study, we, as post-secondary mathematics teacher educators, built on an existing effort to improve pre-service teachers' mathematical vocabulary understandings by intentionally addressing their struggles related to polygonal area formulas. Utilizing cognitive load theory and Bruner's levels of developmental…

A lack of belongingness is an area of concern for developmental math students due to negative implications for academic outcomes. Many college students placed into remedial math courses lack a sense of belonging within the math classroom. This study identified evidence of factors of belongingness among freshman college students who participated in…

Modern educational settings have been heavily integrated and dependent upon the use of technology. To keep up with the rigorous demands of Common Core State Standards, California schools have emphasized technology dependency to augment academic performance with today's schools. The purpose of the study focused on parental perception of technology…

Indigenous peoples have rich ways of knowing that have been passed down for generations. Specifically, mathematical ways of knowing are embedded within a nation's and community's language, culture, and place. This article describes how Turtle Mountain Community College now teaches three courses on Ojibwe mathematics which were designed and…

Teaching children with autism spectrum disorder (ASD) academic skills supports their future opportunities. For example, early number sense skills are predictive of future mathematical success for all children including children with ASD. Yet, research on foundational early childhood mathematics skills of children with ASD is limited. This study…

This study aims to develop a conceptual framework regarding practitioner knowledge and describe how one mathematics teacher generates her practitioner knowledge based on the framework. The characteristic of this framework is a combination of static and dynamic aspects of knowledge based on the teacher's perception and interpretation. The research…

Integrating biology and mathematics can potentially solve problems associated with students' inability to solve quantitative biology problems. To face this issue, we embarked on a project to develop biological and mathematical content-based comics for elementary school students. It would assist them in gaining early comfort with transdisciplinary…

In this paper, we present a computerized tool developed specifically for a study that examined the development of creative thinking among third and fourth graders, following multidisciplinary instruction that combined mathematics and music. The computerized tool included closed and open questions. The closed questions allowed the students to…
