To address the challenge of low academic results in mathematics the district adopted a new curriculum. After three years of utilizing a problem-based learning mathematics curriculum resource, there is a varied degree of utilization and teacher buy-in with regards to a district implemented problem-based curriculum. During this time, there has been…

This dissertation study investigated secondary mathematics teachers' designing and enacting lessons to draw on students' multiple mathematical knowledge bases. The ultimate objective of incorporating open spaces in mathematics lessons is to support students from culturally and linguistically diverse backgrounds in developing mathematical…

This study explores the development and implementation of a five-day curriculum designed to enhance students' understanding of algebraic concepts through the integration of educational robotics and growth mindset principles. The study is structured around three research questions that investigate influences on decision-making in curriculum design,…

The number of socially and linguistically varied students at two local high schools in a southwestern state located in the United States has greatly increased. Since the 2018-2022 school years, English language learners (ELLs) scored low on the state achievement mathematics test scores. The problem was teachers were challenged to support the…

Teachers choose to supplement their curriculum for various reasons (Drake, 2010) and use online resources to search for and choose these supplements for their curriculum (Silver, 2022). TeachersPayTeachers.com (TPT) is a popular choice for online curriculum resources. TPT is a virtual resource pool that allows teachers to create and share…

The purpose of this qualitative interpretive study was to understand the ways teachers were influenced in their curricular and instructional decision-making processes in a freshman level mathematics class. Understanding what influences teachers' decision-making processes, and how (the ways) these processes were influenced, may lead to improved…

A common educational assumption is that coherence is a pre-requisite for a "good" curriculum. Indeed, in mathematics education this perspective has persisted both nationally and internationally as a foundational principle for curriculum design, reform, and evaluation. While curricular coherence is often unquestioningly accepted as…

National mathematics achievement results show that elementary students in the United States are not increasing in cognitive ability or critical thinking skills (NAEP, 2020). For this increase, mathematically promising students require more opportunities for cognitively demanding mathematics instruction. As a result, this descriptive study focused…

The present study investigated the math self-efficacy of homeschool parents and whether there was a correlation between parental math self-efficacy (PMSE) and parents' choice of mathematics curriculum. A simple random sample of parents with at least one child enrolled in Classical Conversations (N = 223) completed a survey to measure their math…

The persistence of a 120 year-old mathematics curriculum despite dramatic changes in society (Dossey et al., 2016; NCTM, 2018) and the failure of the US mathematics education system to achieve many of its stated aims, especially for students from traditionally marginalized populations (Attridge & Inglis, 2013; Carnevale & Desrochers,…

This work explores the complex cognitive processes students engage in when addressing contextual tasks requiring linear and exponential models. Grounded within Piagetian constructivism and the Knowledge in Pieces (KiP) epistemological perspective (diSessa, 1993, 2018), this empirical study in a clinical setting develops a Microgenetic Learning…

This quantitative research study considered three academic factors, seven student-level variables, and four success measures across ten years of academic data related to undergraduate remedial mathematics beginning with the 2009-2010 academic year and ending with the 2018-2019 academic year. Secondary data was used to determine if there was a…

The purpose of this phenomenological study was to explore the adult students' perceptions of Game-Based Learning's mitigation of math anxiety in a STEM math course at a mid-sized university in Southeast Texas. The participants in this study included 11 students who identified as adult learners with math anxiety taught by the researcher in a STEM…

Over the past four years, Skyline Middle School (SMS) has implemented high-quality instructional materials and made numerous attempts to create a school-wide Response to Intervention (RtI) program to support students struggling with classroom mathematics instruction. Despite these efforts, students' mathematics proficiency levels as measured by…

Currently, teachers increasingly use digital curriculum resources in the design and enactment of their lessons. Using digital resources changes how teachers interact with their resources and how students interact with teachers and content, placing new demands on teachers. This study examines this context. The research questions guiding this study…
