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:…

The incorporation of Computer Science teaching in educational systems has increased in recent years. Given international interest, Chile has promoted projects to promote the development of students' digital skills. Focusing on this new educational context, this research reports the results regarding the identification of computational concepts and…

A lack of access to a sequence of introductory to top-level curricula in rural schools has widened the achievement disparity between rural and urban students and influenced the number of college degree holders in rural areas. Recently, surging diversity and differentiation in income levels across nonurbanized areas can serve as determinants of the…

The following study shows how reparameterizations and constraints of the general linear model can serve to parse quantitative and qualitative aspects of predictors. We demonstrate three different approaches. The study uses data from the High School Longitudinal Study of 2009 on mathematics course-taking and achievement as an example. Results show…

Students who are affiliated with the United States Armed Forces will transition every two to four years depending on their parents' career. The students who move may have educational gaps in mathematics because of a United States Armed Forces move occurring in the middle of a school year. The problem of practice addresses the educational gaps that…
