We investigate the impact of external differentiation and vocational orientation of (lower and upper) secondary education on country variation in the mean numeracy skills of, and skills gaps between, adults with low and intermediate formal qualifications. We use data on 30- to 44-year-olds in 18 countries from the 2011-12 round of the Program for…

Based on years of research with early childhood teachers, author Allen Rosales provides an approach to create an emergent math curriculum that integrates children's interests with math concepts. The mathematizing approach is different from traditional math curriculums, as it immerses children in a process that is designed to develop their…

This paper describes the lesson practices at one very remote school that has been highly successful in numeracy. Drawing on a significant body of diverse research that promotes quality teaching and learning, this case study describes the features of the practice that have been implemented across the school. Teachers' voices provide both…

The United States and Canada are destination countries for immigrants, attracting more than half of all Organization for Economic Cooperation and Development (OECD) immigrants and two-thirds of the OECD immigrants who have received tertiary education. Initial comparisons of immigrant wages to their native peers using data the Program for the…

Gender differences in mathematical achievement have been examined in a wide range of age groups but only a few studies addressed this issue in preschool children. We compared preschool girls (n?=?570) and boys (n?=?524) from Germany with regard to numerical competencies. Differences in overall group means and the frequency of representation at…

Understanding what numbers are means knowing several things. It means knowing how counting relates to numbers (called "the cardinal principle" or "cardinality"); it means knowing that each number is generated by adding one to the previous number (called "the successor function' or "succession"), and it means…

Well-designed mathematics instruction focused on concepts and problem-solving skills associated with measurement and data analysis can build a foundational understanding for more advanced mathematics. This study investigated the efficacy of the Precision Mathematics Level 1 (PM-L1) intervention, a Tier 2 print- and technology-based mathematics…

In 2010, the province of Ontario introduced a new universal two-year play-based full-day kindergarten program. The authors exploited the phasing-in of this program over five years, allowing a natural experiment in which children from full-day kindergarten could be compared with those from half-day kindergarten in matched neighborhoods. Children (N…

Teaching mathematics to children with autism is an area with limited research evidence. In this study we developed a teaching manual based on Maths Recovery, a numeracy programme designed for typically developing children. Six children with autism participated in the study and received daily numeracy teaching over a 20-week period. Our aims were…

This study assessed whether a sample of two hundred seven 3- to 7-year-olds could interpret multidigit numerals using simple identification and comparison tasks. Contrary to the view that young children do not understand place value, even 3-year-olds demonstrated some competence on these tasks. Ceiling was reached by first grade. When training was…

This unique Australian paper presents a study involving a Western Victorian District High School year nine mathematics class using social justice pedagogy to learn Mathematics. The class was comprised of gifted students, mainstream students and students who had diagnosed learning disabilities, all key foci in Australian Education research. The…

The ability to use numerical information in different contexts is a major goal of mathematics education. In health risk communication, outcomes of a medical condition are frequently expressed in probabilities. Difficulties to accurately represent probability information can result in unfavourable medical decisions. To support individuals with…

The purpose of this longitudinal study is to investigate whether an early childhood intervention using an explicit and transparent number naming system will have a lasting benefit to English and Spanish speaking children in their mathematics achievement related to number sense by accelerating their acquisition of concepts of numeracy and place…

Favourable home learning environments (HLEs) support children's literacy, numeracy and social development. In large-scale research, HLE is typically measured by self-report survey, but there is little consistency between studies and many different items and latent constructs are observed. Little is known about the stability of these items and…

Underperformance in math is a problem with increasing prevalence, complex etiology, and severe repercussions. This study examined the etiological heterogeneity of math performance in a sample of 264 pairs of 12-year-old twins assessed on measures of math achievement, numerosity, and math anxiety. Latent profile analysis indicated 5 groupings of…
