Acknowledging evidence that the ability to estimate has major consequences for both later mathematics learning and real-world functionality, this paper examines the national mathematics curriculum for compulsory school for each of Denmark, Norway and Sweden for the estimation-related opportunities it offers children. Framed against four…

Close to a decade ago Hong Kong completed the implementation of a New three-year Senior Secondary (NSS) curriculum by introducing the Hong Kong Diploma of (HKDSE) examination. Because mathematics is one of the core subjects intricately involved in this education reform, it is necessary to evaluate the connection between the Hong Kong S1 - S6…

Across the world, standards and practices for preparing teachers of mathematics emphasize the importance of math modeling (MM) in developing students' mathematical thinking. The aim of this research study was to develop the Mathematical Modeling Knowledge Scale (MAMKS), capable of determining preservice teachers' (PSTs') knowledge of MM. The study…

Despite well-designed curriculum materials, teachers often face challenges implementing them due to diverse classroom needs. This paper investigates whether large language models (LLMs) can support middle school math teachers by helping create high-quality curriculum scaffolds, which we define as the adaptations and supplements teachers employ to…

Professional learning (PL) programs increasingly rely on the expertise of instructional coaches in supporting teacher learning and instructional change. To continue to improve the use of coaching as a lever of teacher PL, it is important to understand how both coaches and teachers understand and view their interactions in the context of such PL…

The goal of this article is to investigate Davydov's concept of the concept against the backdrop of its philosophical system, namely, dialectical materialism. In the first part, after briefly sketching the context of Davydov's work, I consider some ontological and epistemological ideas on which Davydov bases his concept of the concept. I pay…

This study explores how five beginning elementary teachers used their mathematics curriculum materials in their first three years of teaching. Prior research suggests that teachers' curriculum material use in their earlier careers may not change significantly from year to year (e.g., Valencia, Place, Martin, & Grossman, 2006). Our…

We know that women are underrepresented in math-intensive fields despite marginal gender differences in mathematical performance. Some researchers believe that societal factors contribute to this problem and have called for more nuanced methodologies to examine why underrepresentation and gender stereotypes about math continue to persist. The…

The numerical ability of Irish students in international and national assessments is weaker than for literacy, particularly among higher-performing students. The aim of this study was to design a national teacher professional development programme to encourage teachers at post-primary level to develop numeracy competency across the post-primary…

This study aims to evaluate mathematics curriculum used in social sciences high schools' preparatory classes based on Stufflebeam (CIPP) evaluation model in terms of context, input, process and product dimensions. With this aim, this study seeks to answer "How is preparatory class mathematics curriculum (PCMC) evaluated in terms of its…

The making of mathematical connections in the classroom plays a dual role. While many studies highlight the importance of connections for the learning of mathematics, others inform of students' difficulties associated with the making of connections. This study aims to characterise the mathematical connections that arise in habitual classroom…

Estimation is an essential competence with a developmental role in the learning of various mathematical topics. Yet, as previous studies highlight, this competence is either excluded or ambivalently included in intended curricula around the world. The current study investigates the estimation-related opportunities in the primary curricula of three…

In this article, we explore Terry Wood's participation in the Purdue Problem-Centered Mathematics Curriculum Project, along with the rich and enduring personal and professional friendships that she built with the classroom teachers who were so important to the project. We highlight connections between these working relationships and the research…

Effective continued professional development (CPD) is critical in preparing teachers for implementing curricular changes. Utilising the professional design framework [Loucks-Horsley, S., Stiles, K. E., Mundry, S. E., Love, N. B., & Hewson, P. W. (2009). "Designing Professional Development for Teachers of Science and Mathematics."…

This is the first of four columns by Tim Erikson which introduces us to the Common Online Data Analysis Platform (CODAP). CODAP is a free, web-based software tool that your students can use for many types of tasks. This first column shows how CODAP can be used for mathematical modelling and where it might fit with the "Australian Curriculum:…
