Background/purpose: This study aimed to investigate the differences among the equations used in estimating the reliability coefficient using the half-split method. These equations demonstrate Spearman-Brown's, Rulon's, Guttman's, Mosier's, Flanagan's, and Horst's. Materials/methods: The study instrument was a 43-item scale for evaluating the…

The purpose of this study was to examine the effects of integrating mathematics into physical education. Participants included 132 fourth grade students from four physical education classes at two schools. In-tact physical education classes were assigned to intervention and control groups. Mathematics activities were integrated into the…

Curriculum reform is an opportunity to refresh programs to meet the needs of current students, but this is not without significant investment from teachers. In this exploratory multiple case study, semi-structured interviews captured teachers' processes of curriculum interpretation for mathematics planning and teaching in a school using scripted…

This conceptual paper puts forward the construct termed "teacher curriculum competence," which is an amalgamation of theoretical or formal and personal practical teacher knowledge and orientations in relation to curriculum. We situate the competence in institutional, political, and philosophical contexts. Drawing on research related to…

The increased relevancy and importance of quantitative literacy (QL) have called for educational reform in undergraduate mathematics course offerings. However, lack of clear guidelines has led to wide variability in the content and outcomes of math courses meant to address QL. Therefore, having an expert consensus regarding content and outcomes…

The interrogation of often unintended practices of marginalisation has gained focus in research on mathematics teaching and mathematics teacher education throughout the last decades. In this introductory survey paper, work against marginalisation in these contexts of mathematics education is viewed in terms of work towards equity, diversity and…

While research on the impact of a Eurocentric curriculum has often focused on marginalized populations in developing nations, it is paramount that scholars also examine the impact of this curriculum on students in the Global North. To this end, this paper begins by first defining and then critiquing what is often referred to as the…

Numerous states use research-based mathematics curricula as a teaching tool to enhance mathematics performance outcomes on state assessment scores. Despite implementation of the Eureka curriculum, students at the study site were still struggling to master Algebra 1 skills sufficiently to pass the Louisiana state exam. The aim of this basic…

Fractions remain one of the most difficult topics to convey to students. Thus, employing professional development programs known for improving the teaching and learning process, such as lesson study, is deemed necessary. This study aims to assess and analyze the strengths and weaknesses of the implemented research lesson using the Mathematical…

Mathematics teachers, are always making and remaking their curricula to better serve the needs of their students. Sometimes, these revisions happen while they are teaching a new task. At other times, as they grow in their thinking, they become aware that some of the tasks they've used for years--and might even name as favorites for their potential…

This study examines prospective elementary teachers' growth and development of competencies, conceptions, and perceptions of mathematical modelling in a mathematics content course for elementary teachers. A series of lessons were implemented that engaged students in the modelling process through modelling tasks. The goal was to capture prospective…

Students are entering the classroom with more technological knowledge than ever before, and to provide enriching learning opportunities, teachers need to be ready to use that background. Elementary mathematics teachers are often provided with technology to use with their mathematics curriculum. However, they do not always receive any guidance or…

Although there have been a huge number of attempts to improve school algebra teaching, several countries are still struggling to improve students algebraic skills. In this study, we focus on the specific case of Sweden where students for several decades have had major problems mastering algebra. In order to get a better understanding of the…

Many states use research-based mathematics curricula as an instructional tool to improve mathematics performance outcomes on state assessment scores. The problem was that despite the implementation of a research-based curriculum, students at XYZ Elementary School (pseudonym) had underperformed on the Partnership for Assessment of Readiness for…

Given the ubiquity of curriculum materials and complexity of their usage, it is imperative that teacher education programs prepare prospective teachers (PSTs) to use curriculum materials. In this paper, we focus on what PSTs notice when they are interacting with curriculum materials, and how their initial impressions of curriculum materials…
