Increasingly, mathematics educators see the importance of representation of diversity in pedagogical texts. The number of identity markers often considered has increased over the previous half century, and now includes, for instance, gender, class, ethnicity, religion, functionality, and sexual orientation. We investigate representation of…

Self-efficacy, the beliefs learners hold about what they can do, develops largely from whether learners perceive and interpret their experiences as successful (i.e., perceived mastery). In mathematics, the relationship between perceived mastery and self-efficacy has been well established. Less is known about the factors that may influence…

In 2014, a team of educators and all of the eighth-grade students at a "failing school" in Nashville, Tennessee, took up the challenge of teaching and learning Algebra 1. This was in the context of a constrained standardized-test-driven public school environment in which less than 20 percent of these students had achieved proficiency in…

This article covers the details of the Zero Mistake Program (ZMP) implemented for senior high school students at Stirling Schools in the regions of Iraq and Kurdistan while preparing for the ministry exams (wezary, baccalaureate). As a result of the findings, recommendations, and outcomes obtained during the preparation for these exams, which are…

The Trends in International Mathematics and Science Study (TIMSS) was administered via computer, eTIMSS, for the first time in 2019. The purpose of this study was to investigate item block position and item format effect on eighth grade mathematics item easiness in low- and high-achieving countries of eTIMSS 2019. Item responses from Chile, Qatar,…

To make up for pandemic-related learning losses, many U.S. public school districts have increased enrollment in their summer school programs. We assessed summer school as a strategy for COVID-19 learning recovery by tracking the academic progress of students who attended summer school in 2022 across eight districts serving 400,000 students. Using…

The purpose of this study was to evaluate the population invariance of equating functions across country subgroups in TIMSS 2015 mathematics tests in relation to the raw-score distribution, DIF, and DTF. We used equipercentile and IRT observed-score equating methods. The results of the study indicate that there is a relationship between the…

School psychologists often administer evidence-based academic interventions such as Explicit Timing in order to increase math fact fluency. However, little is known about the efficacy of adapting Explicit Timing interventions to be used in a virtual format. This dissertation examines the use of virtually delivered Explicit Timing interventions as…

This study examines the factors affecting the mathematics achievement of 8th-grade students in Türkiye using data from the TIMSS in 2011, 2015, and 2019. The data were analysed with multilevel (two-level) modelling. The first level was the student, and the second level was the school. At the student level, such affective characteristics as…

The aim of this study is to classify the subjects and skills of middle school mathematics course in the context of MATH Taxonomy and to determine their relations. For this purpose, the questions and answers related to the mathematics subtest of a national exam were analyzed over the answers of 20154 students. The study continued with the analysis…

This quantitative study focused on the Algebra 1 End-Of-Course Exam Program (EOCEP) exam that students must complete if they are enrolled in beginning algebra classes. The research focused on one school, the high schools within this school's district, and South Carolina. The purpose of the study was to determine if there was a relationship between…

Textbooks play a vital role in the Nepali education system since they are one of the main resources for teaching and learning mathematics. Because of poor physical infrastructure and inadequate educational resources, both teachers and students heavily rely on textbooks. In this regard, this study investigated the mathematics textbook authors'…

The purpose of this action research study was to develop and implement common formative assessments for mathematics teachers to inform instructional practices. To address the purpose of this action research study, the following research questions guided this study: 1. How can the district instructional leadership team support professional learning…

Assessment is often used to promote learning, but the mechanisms of how assessment relates to epistemology -- knowledge and knowing -- have been scarcely studied and theorised. In this study, we examine students' epistemic resources in relation assessment in the context of university mathematics education. We draw on the theoretical framework of…

Big Ideas can be seen as overarching concepts that occur in various mathematical topics and strands within a syllabus. Within our project on Big Ideas in School Mathematics, we developed instruments to measure two Big Ideas: Equivalence and Proportionality. The instruments we developed seek to assess students' ability to see these Big Ideas as…
