Learning disabilities are the most common eligibility category in which children qualify for special education services. Despite this, there is surprisingly little current information on the prevalence and needs of children with math disabilities, and even less information on interventions to support children in schools. This dissertation aimed to…

Mathematics teachers at the local middle school located in a southeastern suburban community were struggling to implement differentiated instruction (DI) strategies in mathematics lessons as presented in professional development (PD) sessions and as directed by school administrators. The purpose of this study was to explore middle school…

The purpose of this phenomenological study was to explore the lived experiences of African American high school students in southeast Colorado who are scoring low on geometry assessments. There are many studies on African American students scoring low on math assessments. However, there are no studies presented in literature on the topic coming…

In the pursuit of continuous improvement in education and closing the achievement gap, educators are experimenting with different environments that will assist students in increasing academic achievement. The media bombards Americans with news about the failing educational system that is being outperformed by counterparts around the world. In this…

Lord's paradox arises from the conflicting inferences obtained from two alternative approaches that are typically used in evaluating the treatment effect using a pre-post test design. The two main approaches for analyzing such data are: (1) to regress the change from pretest to posttest on the treatment indicator (change score approach; CS); (2)…

Background/context: Student heterogeneity is a persistent and fundamental challenge in all school systems. In many countries, including Norway, politicians and actors within the educational sector have increased the use of additional teachers, teacher assistants, and special education teachers to respond to this challenge (Bonesrønning, Iversen…

Diverse stakeholders have an interest in understanding how teacher characteristics--their preparation and experience, knowledge, and mind-sets and habits--relate to students' outcomes in mathematics. Past research has extensively explored this issue but often examined each characteristic in isolation. Drawing on data from roughly 300 fourth- and…

The 2-year Philippine Senior High School (SHS) commenced only in 2016. This phenomenographic study aimed to describe, explain and explore the teaching of SHS Mathematics to include problems encountered and interventions done by the teachers. Two schools in Quezon City were purposively chosen to be the study site with a maximal variation sampling…

Interest in creativity in mathematics education research is increasing, and the field of research is growing. Yet, research on creativity and the "notions" (we use this wording to accumulate understandings, beliefs, and ideas about the construct) of creativity that are addressed in empirical research are diverse and difficult to organize…

Relational language is thought to influence mathematical skills. This study examines the association between "relational language" and "number relation skills"--knowledge of cardinal, ordinal, and spatial principles--among 104 U.S. kindergartners (5.9 years; 44% boys; 37% White, 25% Black, 14% Asian, 24% other) in the 2017-2018…

The study aims to explore how the mathematics teachers taking post-graduate education use their Algebra knowledge for the expression, "You can't add apples and pears" that is expressed in almost every segment of the society, in creating mathematical content. The data of the research consisted of the written answers of the thirty-seven…

Early mathematics plays an important role in introducing foundational concepts for number sense in children. One of the critical areas of learning is the establishment of a linear view of numbers. It is essential to create opportunities for young children to understand that numbers are equally spaced on the number line and that they increase in…

Oblique angle collisions of two penny coins on a smooth, horizontal surface were filmed with a video camera to investigate the physics of the collision process. If one of the coins is initially at rest, then the two coins emerge approximately at right angles, as commonly observed in billiard ball collisions and in puck collisions on an air table.…

The important role of student agency in collaborative problem-solving has been acknowledged in previous mathematics education research. However, what remains unknown are the processes of agency in open-ended tasks that draw on real-life contexts and demand argumentation beyond "mathematical". In this study, we analyse a video recording…

The nineteenth century has been characterised as a period in which mathematics proper acquired a disciplinary and institutional autonomy. This article explores the intertwining of three intersecting worlds of the history of mathematics inasmuch as it engages with historicising the pursuit of novel mathematics, the history of disciplines and, more…
