Students with disabilities often encounter challenges when solving mathematical word problems. This case study used an Improvement Science approach in a 15-week Plan-Do-Study-Act cycle where leadership approaches and collaborative structures were utilized to support teachers as they implemented problem-solving and goal-setting strategy to help…

The purpose of this mixed method study is to determine the effectiveness of the corequisite model on collegiate mathematics developmental education. Corequisite models are designed to allow students who place into pre-college level courses to complete the prerequisite material and college-level coursework simultaneously in their first semester.…

Mathematics is integral to today's world, but many students fear solving arithmetic problems. In the U.S., more than 82% of students in grades 7th through 10th fear math. In 2021, 80% of Florida high school students failed Algebra I end-of-course exam. Math anxiety has negatively impacted students' social cognitive, and academic skills. This basic…

The goal of this qualitative single case study was to explore the effects of expressive writing as a self-regulation strategy in a suburban high school algebra classroom for reducing self-reported math anxiety. A variety of stressors related to the school environment impact adolescents, including peer dynamics, stress from the high school…

In this quasi-experimental pretest-posttest study we examined the effects of differentiated instruction (DI) in within-class ability groupings of 246 Montenegrin fourth-graders and their ability to solve algebraic equations. We assessed 2 parallel student groups at equal achievement levels to compare DI, in which teaching and work modes were…

A vast body of work highlights executive functions (EFs) as robust correlates of mathematics achievement over the primary and preschool years. Yet, despite such correlational evidence, there is limited evidence that EF interventions yield improvements in early years mathematics. As intervention studies are a powerful tool to move beyond…

The author explored the extent to which policy could be a source of sustainable professional development for elementary teachers' mathematical knowledge for teaching. The study involved three policies in England: the National Numeracy Strategy and the Primary National Strategy, introduced in response to concerns regarding mathematics teaching and…

This dissertation aimed to investigate the effectiveness of educational technology tools on high school students' Algebra I fundamental skills from the perspectives of high school mathematics teachers. A mixed-methodology approach, including online surveys and open- ended questions, was used to capture the teachers' perspectives. The study…

In this study, we investigated prospective secondary mathematics teachers' development of a meaning for the Cartesian form of complex numbers by examining the roots of quadratic equations through quantitative reasoning. Data included transcripts of the two sessions of classroom teaching experiments prospective teachers participated in, written…

The worked example effect has been well documented within the framework of Cognitive Load Theory (CLT), which suggests that teaching with examples would be superior to engaging in unguided problem solving, particularly for novices, as using worked examples would reduce their cognitive load, compared to solving problems, thus facilitating knowledge…

Matters of identity are personally and socially constructed and do not always align with teacher perceptions. When this occurs, it can cause internal tensions in ways students navigate their sense of being in schooling and in society as a whole. These tensions can also impact students' mathematical identity and their motivations within mathematics…

Situations where students encounter mathematical "impasses" -- instances where their current discourse is incommensurable with the discourse demanded to solve a task -- have the potential to stir emotional responses of different types. They can engender feelings of confusion and bafflement, or even embarrassment, or alternatively open…

Using narrative inquiry, I share the beginning stories of the instructional visions of secondary mathematics teachers throughout their undergraduate studies of pedagogy and content-specific methods and evidenced in undergraduate coursework and student teaching experience. Guided by Munter's (2014) Visions of High-Quality Mathematics Instruction…

How teachers can experience adaptive professional development (PD) experiences is still understudied in the literature on teacher learning, which for the most part reflects an emphasis on learning outcomes rather than the process of learning. In this study, we use a situated perspective on teacher learning to investigate the coevolution of a…

This paper introduces two theoretical constructs, open-loop covariation and closed-loop covariation, that combine covariational reasoning and causality to characterize the way that three preservice mathematics teachers conceptualize a feedback loop relationship in a mathematical task related to climate change. The study's results suggest that the…
