Life in the twenty-first century requires education to integrate knowledge, attitudes, skills, and mastery of information and communication technology (ICT). An example of the skills needed in the twenty-first century is computational thinking. This study aims to develop computational thinking-skill tasks on numbers and arithmetic based on the…

This study investigates the application of the fuzzy logic method for scoring open-ended items, specifically comparing its effectiveness against traditional scoring methods. Utilizing the fuzzy TOPSIS method within the mathematics domain, this research established seven criteria for evaluating open-ended responses, developed in consultation with…

In this study, the authors investigate the written feedback provided to primary and secondary pre-service teachers studying a specialisation in mathematics. The analysis focuses on 16 written reports completed by mentor teachers during the penultimate year placement of pre-service teachers. The evaluation employs a framework informed by the…

This study elaborates on the pivotal roles of mathematical and statistical models in data-driven predictions in an integrated STEM context using the case of Year 4 students: (?) "a descriptive means" to describe the features of trends and variability of data and (?) "an explanatory means" to explain causal relationships behind…

The Program for International Student Assessment (PISA) 2012 utilized data from 63 countries and economies to generate research questions that centered on the contribution of mathematics self-efficacy, opportunity to learn (OTL), and how their interplay affected students' mathematical performance. This study reveals that in a majority of the…

This essay aims to advance the debate on the conceptualization of interdisciplinarity in mathematics education by presenting the idea of the border as a dynamic semiotic cross-cultural space. We refer to three theories, that originate in different research fields and use specific languages: De Luca Picione and Valsiner's idea of the border as a…

This study aims to determine the effectiveness of GeoGebra-assisted learning on students' mathematical representation through a meta-analysis study and possible moderator variables to moderate it. Experimental studies were obtained from Google Scholar and ERIC databases and then included in this meta-analysis study were 23 studies that met the…

Covariational reasoning, essential for understanding functions and modeling dynamic situations, is traditionally introduced in secondary education. This paper proposes introducing covariational reasoning in primary school settings through an artifact, the Tracer. Previous studies investigate a covariational approach to functions with younger…

There is widespread speculation and some evidence that grades and grading standards changed during the pandemic, making higher grades relatively easier to achieve. In this paper we use longitudinal data from students in Washington State to investigate middle and high school grades in math, science, and English pre- and post-pandemic. Our…

In this paper, we consider the design of capstone courses to prepare university students for secondary school teaching professions in initial training. Our aim is to prepare prospective teachers to develop an approach for doing mathematics which they then impart to their pupils. This posture involves systematically questioning the mathematical…

This contribution explores the teaching of graph theory in the context of engineering education. We examine how teachers use collectively designed resources in terms of their backgrounds. After a literature review, we justify the choice to develop an analytical framework for studying the materials in terms of connections to be established in the…

Coming from a social perspective, we introduce a classroom organizational frame, where students' proofs progress from collaborative construction in small groups, through whole-class presentation at the board by one of the constructors, to a posteriori reflection. This design is informed by a view on proofs as successive social processes in the…

Across multiple countries the term "big ideas" of mathematics has become a construct advocated as important for teachers' mathematical knowledge. Indeed, several policy or position statement documents about math learning in the United States (U.S.) have stated that "big ideas" of math is a crucial construct for teacher…

Assessing student teachers' ability to pose mathematical reasoning problems within their experiences in teacher education is essential due to their increasing challenges in preparing for 21st-century learning. This study investigates the quality of mathematical reasoning problems posed by student teachers. Thirty-four student teachers at a public…

The aim of this study was to investigate individual differences in mathematical problem-solving among 3- to 5-year-old children (N = 328; n[subscript 3-year-olds] = 115, n[subscript 4-year-olds] = 167, n[subscript 5-year-olds] = 46). First, we examined the extent to which children in this age group were able to solve open and closed non-routine…
