Psychological interventions offer a unique approach to enhancing the educational experience for university students. Unlike traditional teaching methods, these interventions directly address cognitive, emotional, and behavioural factors without requiring changes to course content, delivery methods, or involvement from the teaching team. This…

The aim of this study was to develop an instrument for assessing sixth-grade students' number sense skills in fractions and decimals. This study was conducted on 452 sixth graders (10-11 years old) from the western region of Turkey. The construct validity of the number sense test (NST) was examined via exploratory factor analysis (EFA) and…

The notion of function is central in all of the secondary curriculum, and indeed functional models appear in almost all higher education that is based on mathematics. However, in secondary education, functions usually appear in restricted and somewhat sterile forms. In this (mostly theoretical) paper, we present a proposal -- exemplified by a…

This study aimed to determine the relationship between attitude, metacognitive awareness, and mathematics reasoning, as well as investigate the role of metacognitive awareness as a mediator. This study examined data from 378 pre-service teachers in Malaysia. The data were gathered by administering questionnaires and a mathematics reasoning…

This paper aims to reveal a teacher's actions to participate in a teaching experiment that supports collective argumentation in teaching triangles at the high school level and to present a teachers' participation in collective argumentation framework. The theoretical perspective adopted in this study is Krummheuer's (1995) collective argumentation…

The main purpose of this research is to examine the informal strategies of fifth and sixth grade students while solving inverse proportional word problems. Multiple case study was used in this study. The research was carried out in a public middle school from a southern city of Türkiye. The participants of the research consist of three fifth and…

As community colleges and systems move away from developmental education and encourage students to enroll in introductory, college-level coursework to complete their math and English requirements, it is critical to provide students with additional academic supports to help them succeed. One such model is the corequisite course, a model that offers…

There is a growing research interest in examining how mathematics teacher educators grow professionally in their practice. In this study, we focus on the experiences of novice mathematics teacher educators who had been secondary mathematics teachers before becoming instructors of an elementary methods course. During individual, semi-structured…

As ideas from data science become more prevalent in secondary curricula, it is important to understand secondary teachers' content knowledge and reasoning about complex data structures and modern visualizations. The purpose of this case study is to explore how secondary teachers make sense of mappings between data and visualizations, especially…

Students with autism spectrum disorder (ASD) are included in the general education classroom more often than ever before. Despite mathematical strengths and early success, these students experience poor outcomes (academic and employment) compared to their typically developing peers. The language of mathematics increases in complexity, use, and…

This article presents a new teaching method that embraces media production as a principle in education, aimed at effectively conveying the philosophy of mathematics. Based upon this premise, the content of the philosophy of mathematics course was reimagined as a digital newspaper, reminiscent of past printed editions. This transformation was…

This qualitative exploratory case study focused on a Professional Development (PD) program for mathematics teachers in the public system, which is an underserved community of teachers in Chile. The study aimed to understand how the program addressed the challenges brought by the pandemic. Using semi-structured interviews and drawing from a…

This single-case study assessed the effectiveness of a mnemonic pegword strategy designed to enhance the multiplication fact fluency of three 6th-grade students who demonstrated persistent learning difficulties in mathematics. A nonconcurrent multiple baseline across subjects design was utilized, incorporating 3-5 baseline sessions followed by…

This study is a secondary analysis of the data collected in a randomized control trial study with sixth graders with mathematics learning difficulties (MLDs). We explored the relation between mathematics anxiety and mathematics performance for students with and without MLD. We further explored whether mathematics vocabulary and computational…

This study examined 11 U.S. textbooks written for prospective teachers to investigate how standard decimal multiplication and division algorithms are presented, especially the rationale of both algorithms. Analytical frameworks of various methods used in different textbooks were developed. The findings suggest that half of the textbooks do not…
