Textbooks have always played an important role in mathematics education. Textbook tasks are widely used by students, so it is important to examine their requirements in order to identify the opportunities students have to learn mathematics. Publishers now produce both printed and digital versions of textbooks. While the requirements of the tasks…

The Rasch/Guttman scenario (RGS) measurement approach is a promising test development methodology. The purpose of this study is to compare the RGS measure of primary school students' motivation against more traditional self-report scales. The Scenario Scale of Extrinsic Motivation toward Math (SSEM-M) and its traditional counterpart were…

Background: Math anxiety is a common experience that interferes with learning and achievement in mathematics. Considering that mathematics learning mostly takes place within the classroom, it is critical to examine how math anxiety develops in this context. Aims: The purpose of the current scoping review was to identify classroom-learning…

Understanding of the equal sign is associated with early algebraic competence in the elementary grades and equation-solving success in middle school. Thus, it is important to find ways to build foundational understanding of the equal sign as a relational symbol. Past work promoted a conception of the equal sign as meaning "the same as".…

Given the significance of functional thinking as one of the main routes to foster early algebraic thinking, in this paper we describe how a current elementary mathematics textbook's unit titled "Pattern and Correspondence" was developed in the Korean context. The following four key instructional elements for fostering functional thinking…

Two examples of mathematical modelling are explored. Firstly, optimising the distance travelled when jumping from a swing is discussed. The second concerns optimising the distance travelled by monkeys when swinging from branch to branch.

Prior studies have identified the impact beliefs have on mathematics instructors' instructional practice, such as their choice to (or not to) lecture. However, the role of instructional context role in influencing beliefs and instruction has not been thoroughly researched. This paper explores how course context and beliefs could impact mathematics…

Creating and developing mathematical models to solve real-world problems is a complex task and students often have difficulties in tackling it successfully. The design and implementation of sequences that help students autonomously develop their ability to solve modelling tasks could be a useful scaffolding tool to foster modelling learning. In…

The present paper documents the design and development of a mobile mathematics application targeted to improve magnitude representation skills. Educational experts worked together with an app developer with the goal of creating an educational app as a math learning tool for children 5-8 years old. The description of the app design processes…

The Tchokwe people lived on the African continent, in Mozambique and Angola. The sona belong to their cultural tradition. The sona are drawings made in the sand by older members of the tribe to tell stories, essential in the youngests' formation. In this article, we show a relationship between the sona and the greatest common divisor (GCD) of two…

This research study investigates how elementary teachers' mathematical knowledge for teaching (MKT) relates to their mathematical self-efficacy (MSE) and whether the MKT can predict the MSE. Researchers administered the MSE scale and the MKT test to 86 in-service elementary mathematics teachers. Two-step regression analyses results indicated that…

This paper aims to describe the design and inspection of the quality of a digital learning platform to diagnose mathematical ability levels of seventh-grade students with regard to the topics of Measurement and Geometry. A total of 517 seventh-grade students from 23 schools in four regions, namely north, northeast, central, and south of Thailand…

Lockwood has argued that taking a set-oriented perspective is critical for successful combinatorial enumeration. To date, however, the research literature has not yet captured the cognitive processes involved in taking such a perspective. In this theoretical paper, we elaborate the constructs of spatial structuring and spatial-numerical linked…

This study examined temporal interrelations among math self-concept and math self-efficacy and their differential relations to two commonly applied math achievement indicators, that is, math achievement test scores and school grades in math. It based on a longitudinal design with four annual assessments of self-concept, self-efficacy, school…

Since policy changes in 2014 about who studies mathematics post-16 in England, the mathematics teaching workforce in further education (FE) colleges has grown and diversified. The question of how best to develop the professional practice of this changing workforce is, however, unresolved. Teachers in a recent national study report the benefits of…
