Estimation is such an important yet sometimes overlooked skill. Enhancing estimation skills through exposing students to enumeration ('how many') problems where they are required to estimate before calculating is a critical aspect of developing number sense (Reys et al., 2012). This article describes a 'how many' problem undertaken with a small…

In this paper, I consider a pervasive myth in mathematics education, that of Plato-formalism. I show that this myth is ahistorical, acultural, and harmful, both for mathematics and for society. I argue that, as teachers, we should reject the myth of Plato-formalism and instead understand mathematics as a human activity. This philosophy humanizes…

In this paper, we highlight a further use of scripting tasks in the work of researchers-teacher-educators, which we present in two parts. In Part 1, we study prospective secondary school mathematics teachers' responses to a scripting task on the topic of functions. The generated examples for a function that satisfies certain constraints provide a…

Supporting pre-service primary teachers to develop the required specialist knowledge for teaching mathematics is a complex task. The knowledge required for mathematics teaching at primary level is multi-faceted and the efficacy of mathematics teaching is inextricably intertwined with a teacher's own beliefs and attitudes about mathematics and…

The school mathematics curriculum development process in Nepal is still conventional. Contextualized mathematics teaching and learning has not been the priority of school education of Nepal. Majority of the school mathematics teachers in Nepal still conceptualize the mathematics and mathematics curriculum from the conformist approach. Thus, this…

The Trends in International Mathematics and Science Study (TIMSS) is one of the most influential assessments of student achievement conducted at regular interval every four years. It provides reliable data about the mathematics and science achievement of students in grade 4 and grade 8, as well as data that informs instruction, curriculum…

A widely used instrument was implemented to ascertain the mathematical modelling competency displayed by a cohort of South African learners in grade 10 and grade 12 of the school mathematics programme in South Africa. The cohort comprised 471 grade 10 and 200 grade 12 learners from schools serving learners from low socio-economic status…

To explore the mathematics learning experiences of those more likely to come from non-traditional educational backgrounds, ten students studying one or two maths units in the Skills for Tertiary Education Preparatory Studies (STEPS) at CQUniversity Australia were interviewed. The aim was to investigate how these students learnt to become…

Purpose: Most literature has focused solely on either knowledge about number sense or understanding of fractions. To fill the research gap, this study examined pupils' abilities in both number sense and fractions. In particular, it investigated Year 4 and Year 5 pupils' use of strategies in developing their fraction sense. Methodology: This study…

Girls' underrepresentation in high-level post-compulsory mathematics is a longstanding issue of concern in many Western nations, with innumerable efforts to increase their participation producing little impact. In this paper, we shed new light on girls' underrepresentation through a post-structural feminist investigation of mathematics teachers'…

This study examined a game-based teaching activity on "Factors and Multiples" designed for the 6th grade students. The game aims to create a differentiated and enriched learning environment targeted the curriculum standard "The students determine prime numbers using their properties. The students find prime numbers using the…

This study examines the effects of activities developed with WEB 2.0 tools based on the 5E learning cycle model on the multiplication achievement of 4th graders. Nonequivalent control group pretest-posttest quasi-experimental design was employed in the study. Two of the three groups that were equivalent in terms of achievement were assigned as…

This study investigated personalization as an innovation that can be used to impact college mathematics achievement. In the reported study, similar tasks using personalized data and teacher-selected data were implemented in courses in both 4-year and 2-year colleges. Pre- and posttests and student work were analyzed to examine the impact of…

The aim of the study was to plan and implement teaching activities for the development of mathematical literacy and evaluate the reflective interviews of pre-service elementary school teachers on developing a mathematics activity for mathematical literacy. Accordingly, the study was conducted in embedded design, one of the mixed method research…

In this study, we designed geometry learning activities so that students could apply newly learned knowledge to solve real-life problems, such as estimating the distance to real objects they find in their local community, measuring objects' length, width, and height, and calculating objects' surface area. Our participating students were divided…
