This book provides a critical review of research in mathematics education published in or about the Australasian region in the four years from 2020 to 2023. Research in Mathematics Education in Australasia 2020-2023 (RiMEA 2020-2023) is the eleventh edition of the four-yearly review of mathematics education research in Australasia. It is compiled…

The Numeracy Kit for Kindergarten 5-Year-Olds (NyKK-5) is a tool to support kindergarten teachers' numeracy practices. Based on a pedagogy of enactment, the NyKK-5 was designed to simulate the types of in-class supports that have been identified as critical elements of effective mathematics professional development (PD). Two groups of teachers…

Effective classroom management is critical to supporting student learning and success in school. However, little research has focused specifically on the impact of classroom management on student mathematics achievement, especially in the early elementary grades or in a small group (i.e., Tier 2) context. To address this need we investigated the…

The shift from additive to multiplicative thinking is challenging for students. A professional learning program was developed that focused on an identified area of need by teachers, namely multiplicative thinking. Program content focused on concepts underpinning multiplicative thinking, pedagogical approaches, challenging tasks, and application to…

A critical challenge for elementary mathematics teachers is meeting the learning needs of all students, especially when there is variability in students' number knowledge. Because young students' number system knowledge (NSK) contributes to future success in mathematics, NSK activities must be designed to engage all students, particularly students…

Evidenced-based mathematics interventions are critical for supporting students with mathematics difficulties. In research and practice, collecting implementation fidelity is important for ensuring that all the core components of the intervention are implemented as designed. Historically, implementation fidelity has been defined as multi-faceted…

Teacher identity provides useful insights into the learning and practices of teachers. The complexity of identity, however, makes it difficult to use in empirical research. An analytical framework with two components is presented. This analytical framework comprises a framework for identity as an embedder-of-numeracy, which clearly defines a…

The case study from Brunei described in this report provides a practical example of how learning outcomes in this area can be improved through the power of teacher coaching. This report explores how the Literacy and Numeracy Coaching Programme (LNCP) -- developed by Brunei's Ministry of Education with technical assistance from the Education…

This mixed methods action research study examined the implementation process and impact of a 9-week Number Talk intervention to build number sense in kindergarten students. Fifty-eight kindergarten students engaged in daily Number Talk lessons for 9 weeks. Qualitative data were collected to evaluate the strengths and challenges of the…

Ireland's government placed a renewed focus on the teaching and learning of numeracy with the publication of a national strategy in 2011. Whole-school planning for numeracy was already a requirement for disadvantaged schools also known as Delivering Equality of Opportunity in Schools (DEIS) in Ireland. This single site case study explored how a…

In this case study, Angela Helsloot, Principal at Allambie Heights Public School, on the Northern Beaches of Sydney, uses data from standardised tests and benchmark reading assessments across the school to show the positive impact that Sounds-Write instruction has had in Kindergarten and Year 1. [For the complete volume, "Systematic Synthetic…

Drawing upon recent theorising of numbers and data, and applications to schooling, this paper reveals how tensions between more accountability-oriented logics, and more contextually-situated conceptions of engagement with data, played out in one school in a regional community in northern Queensland, Australia. The research reveals that at the same…

It is widely acknowledged that teaching and learning the language of mathematics is essential for the development of mathematical proficiency. Recent research highlights the need for explicit vocabulary instruction in mathematics. The Promoting Early Number Talk (PENT) project explored the effect of 'Number Talk' -- a resource book to promote…

Research interest in numeracy is growing as a result of increased understanding of the impact of low levels of numeracy. However, there has been little research on factors that influence how teachers implement learning from professional development interventions to support teachers to promote numeracy learning. This paper reports on how a…
