Learning and teaching mathematics can be challenging, especially considering its importance for academic, occupational, and personal success, yet disparities persist in achievement among diverse racial and ethnic groups. Racial inequality, educational bias, and injustice impact success in mathematics education, with White and Asian-American…

The increased reliance on Big Data Analytics (BDA) in society, politics, policy, and industry has catalyzed conversations related to the need for promoting ethical reasoning and decision-making in the mathematical sciences. While the majority of professional data scientists today come from privileged positions in society, those processed by the…

U.S. society perceived some Asian immigrants as a model minority, even assuming that Asian students would be good at mathematics. However, the narratives and experiences of Korean immigrant parents and their children were not discussed in these perspectives. The purpose of this study is to understand the interactions and reasoning of Korean…

There is a persistent and growing global call to examine, challenge, and transform exclusionary structures and systems within mathematics education (Laursen & Austin, 2020; Reinholz et al., 2019; Thomas & Drake, 2016; Wagner et al., 2020). An important component of this call examines students' mathematical identity. While a growing body of…

The widespread of online education is clear and the demand for online education is increasing rapidly, so the quality of offered online courses is urging. During COVID-19 restrictions, unprepared institutions, instructors, and students for online education were clear, especially in STEM. So there is a need for more research on online mathematics…

The National Council of Teachers of Mathematics (NCTM) vision for mathematics education is to provide every student with high-quality instruction from highly effective teachers. Achieving this goal requires a solid mathematics curriculum, competent and experienced teachers who can integrate instruction with assessment, classrooms with the proper…

Educator preparation programs design their coursework and field experiences to help future teachers with knowledge, skills, and abilities to effectively teach mathematics. However, implementation of mathematical pedagogy and content has been seen as challenging for many school systems. Elementary and middle school teachers' experiences in their…

The purpose of this study was to determine how secondary mathematics education changes in Hungary between 1867 and 1956 were reflected in journal articles of that time. In an attempt to accomplish this purpose, the researcher sought to identify which major political and socioeconomic factors affected the role and content of periodicals, how the…

This descriptive and interpretive multi-case study investigated secondary prospective teachers' (PTs') beliefs about mathematical authority and how their student teaching experience(s) influenced their beliefs. The theoretical framework guiding this study was comprised of a novel definition for mathematical authority I developed, a conception of…

Facilitating productive mathematical discussions is considered a core practice of mathematics education. The complexity of this teaching practice presents the need for pedagogical tools to provide structure for preservice teachers (PST) developing their practice, yet little is known about "how" PSTs use these tools. This multiple case…

Research suggests that special education teachers lack the pedagogical expertise and content knowledge needed to teach core mathematics standards and to develop the mathematical reasoning of fifth- and sixth-grade students with a mathematics learning disability (MLD). This study used a multiple-baseline design with randomization to examine the…

This action research study explores the interplay between language acquisition and high school mathematics education, particularly for multilingual learners. The study challenges conventional, segregated approaches to math and language learning that emphasize formulaic memorization and algorithmic methods, contributing to the "math…

Undergraduate mathematics education research focused on Introduction to Proofs courses has gained traction as more students are experiencing challenges in their proof-based courses. While studies have analyzed the teaching and learning of proofs, there is a growing need for research in students' understanding of mathematical logic and set theory…

Since the 1960s, there has been an effort among the mathematical education community to shift instructional practices from a focus on arithmetic, memorizing rules, and completing practice worksheets to instructional practices that allow students to see mathematics as content that requires thinking and pattern explorations. Many mathematics…

This dissertation seeks to investigate how digital gestures connect to students' mathematical understanding when playing "From Here to There!" (FH2T). This investigation explores the intersection of three fields, game-based learning, embodied cognition, and mathematics education. I used three studies which break down the different…
