In order to investigate pre-service teachers (PSTs') understandings of the terms mathematics and numeracy, the authors conducted a study at one Australian university. The PSTs were enrolled in a mandatory unit about numeracy across the curriculum, in which both teachers' and students' numeracy capabilities were considered. The study took place…

The interpretation of numerals has been traditionally debated across disciplines including, but not limited to, Linguistics, Developmental Psychology, and Philosophy. A big portion of the debate concentrates on the ontology of numerals, i.e., their basic meaning, and the mechanisms by which (non) exact interpretations (e.g., at least) are derived.…

At the beginning of the 21st century, "number sense" was listed as one of the core words in the mathematics curriculum of compulsory education in China, and it has now become one of the core competencies of primary school mathematics. It is necessary to determine the development of number sense of first-grade primary school students (6-7…

Governments and policymakers around the world are encouraging teachers to teach numeracy across the curriculum. This paper proposes a theoretical framework for the knowledge required to teach numeracy across multiple disciplines. The concept of teacher knowledge is complex and consists of many different facets of knowledge. This paper proposes a…

Developing students' reading and numeracy skills remain key goals of contemporary schooling. In Australia, the National Assessment Program -- Literacy and Numeracy (NAPLAN) tests have assessed these skills since 2008. Previous research found a significant gender gap in favour of females for the NAPLAN writing test, yet no study has examined…

Exploring individual differences and looking beyond averaged parameters of early numeracy in young children with mild intellectual disabilities has become an area of interest to many researchers worldwide. This study aimed to identify the different profiles of early numeracy skills in young children with mild intellectual disabilities. For this…

Early numerical skills are important not only for later mathematical achievement but for overall achievement and are associated with later income, health, and quality of life. Socioeconomic disparities in numerical skills are visible before children begin school, and widen throughout schooling. It is, therefore, important to support the…

Symbolic numeracy first emerges as children learn the meanings of number words and how to use them to precisely count sets of objects. This development starts before children enter school and forms a foundation for lifelong mathematics achievement. Despite its importance, exactly how children acquire this basic knowledge is unclear. Here we test…

Number sense is a key indicator of students' future academic success. Students from low socio-economic backgrounds often come to kindergarten lacking number sense skills that other students acquire before they begin formal schooling. Small-group intervention that is focused on number sense skills is an effective way to address this foundational…

Higher numeracy is associated with better comprehension and use of numeric information as well as reduced susceptibility to some decision biases. We extended this line of work by showing that increased numeracy predicted probability maximizing (versus matching) as well as a better appreciation of large sample sizes. At the same time, we replicated…

The present study examined patterns of number-related utterances and actions directed to 9-month-old infants by their parents. An ethnically and economically diverse sample of 86 families participated in structured play sessions conducted separately with the mothers and fathers of each infant. Data were coded for eight math talk categories, and…

This study assessed the effectiveness of a program aimed at improving the early numeracy skills of students with moderate intellectual disability. The persistence of the acquired skills and the program's impact on learning were monitored. Feedback from the students and their mothers was also gathered. Using a multiple-probe design across subjects,…

Research and practice that builds on family strengths is uniquely positioned to support children's math learning in ecologically valid and culturally meaningful ways. Yet, there is little specificity as to what it means to take a strengths-based approach in early math research. We propose a conceptual framework for studying early math from a…

During the 2019 General Session, the Legislature passed Senate Bill 166, "School Readiness Amendments", to improve the coordination and alignment of preschool programming. This report is provided to the Education Interim Committee as a summary of an evaluation of and the efficacy of the High Quality School Readiness (HQSR) Grant…

Number-recognition tasks, such as the how-many task, involve set-to-word mapping, and number-creation tasks, such as the give-n task, entail word-to-set mapping. The present study involved comparing sixty 3-year-olds' performance on the two tasks with collections of one to three items over three time points about 3 weeks apart. Inconsistent with…
