The concept of determinant plays a central role in many linear algebra concepts and is also applied to other branches of mathematics and science. In this study, we focus on the application of determinant and inverse matrix concepts, in solving systems of equations by a group of 116 in-service mathematics teachers who were studying the topic at a…

Teaching mathematics requires a wide range of knowledge, including types of mathematical knowledge specialized to the work of teaching. Because specialized content knowledge is a form of professional knowledge, it is important to emphasize in professional preparation. In this paper, we present results comparing the performance of prospective and…

We report on a study focused on identifying how the notion of "the mathematician" is constructed in lower secondary Mexican mathematics textbooks. To conduct the study, we adopted a Foucauldian approach that allows us to identify the way in which the notion of the mathematician is constructed but also to delineate the possible effects…

Rapid automatized naming (RAN) is associated with children's arithmetic performance, which is multifactorial by nature and consists of arithmetic fluency, arithmetic procedure, and word problems. Yet, it is unclear whether RAN can predict all key aspects of arithmetic skills independently and what cognitive mechanisms may explain this relation.…

Researchers and reformers across multiple areas of scholarship have challenged the idea of mathematics as fixed, politically neutral, and value-free. Ethnomathematics has brought attention to the mathematical practices of particular cultural groups that differ from Western ways of mathematical understanding. These practices raise the following…

Exponential functions are an integral component of the secondary mathematics curriculum with which students struggle. Inherent difficulties students have had around the topic of exponential functions suggested a need for thinking about and examining the teaching and learning related to this content. This study presented the mathematical ideas made…

Quantitative Reasoning (QR) is essential for today's students, yet most higher education institutions have not effectively addressed this issue. This study investigates students' quantitative reasoning in STEM and Non-STEM math pathways using a non-proprietary, NSF grant-funded instrument, the Quantitative Literacy & Reasoning Assessment…

The aims of this research was to find the effectiveness of learning devices based on realistic mathematics education, as well as improving mathematic spatial ability and motivation of SMP Negeri 2 Pulo Bandring students' grade IX. This research is a development research using the Dick & Carey development model. The results of the analysis of…

Students' approaches to learning are heavily researched in higher education and are of particular concern in the field of mathematics where many students have been found to struggle with the transition to university mathematics. This article outlines a mixed methods study which sought to describe undergraduate mathematicians' approaches to…

Many research studies have sought to explain why NCTM's vision for mathematics classrooms has not had greater impact on everyday instruction, with teacher beliefs often identified as an explanatory variable. Using instructional exchanges as a theoretical construct, this study explores the influence of teachers' institutional positions on the…

Embedding mathematics in a relatable context has changed the way Christie Henderson's elementary students view the subject. In this article, Henderson discusses how presenting mathematics through a relatable context enables students to visualize the math and make a pictorial representation to aid them in solving it. When relevant and relatable…

Babies and infants love mathematics. Give babies a set of blocks, and they will build and order them, fascinated by the ways the edges line up. Children will look up at the sky and be delighted by the V formations in which birds fly. Count a set of objects with a young child and then move the objects and count them again, and they will be…

The transition from primary to secondary school is regarded as one of the most difficult crossings in students' educational careers. The move, which typically occurs between the ages of twelve and fourteen, can be particularly pronounced for mathematics. This article describes the results of a questionnaire distributed in the Republic of Ireland…

Competence with fractions is foundational to acquiring more advanced mathematical skills. However, achieving competency with fractions is challenging for many students, especially for those with mathematics learning difficulties who often lack foundational skill with whole numbers. Teaching fractions is also challenging for many teachers as they…

The mathematical reasoning ability is one of the essential hard skills of a student, especially in solving everyday problems. In supporting the achievement of this mathematical reasoning ability, meaningful teaching materials are an essential part of keeping exciting and not dull a learning process. This study aimed to design and develop an…
