The number line estimation task is frequently used to measure children's numerical magnitude understanding. It is unclear whether the resulting straight, horizontal, left-to-right-oriented estimate patterns indicate task constraints or children's intuitive number--space mapping. Three- to six-year-old children (N = 72, M[subscript age] = 4.89, 56%…

The approximate number system (ANS) is foundational to numerical cognition. Whereas some studies hint at intact ANS skills in individuals with Down syndrome (DS), others report impaired ANS abilities. To reconcile these discrepant findings, we investigated ANS skills of children with DS and typically developing (TD) children in a non-symbolic…

Previous research focused on individuals' background, contexts and cognitive performance in education, work, and life. Given the increasing number of people living alone temporarily, the question arises whether the frequent use of skills, including social skills, relates to individuals' later positively self-evaluated skills and social lives.…

The Survey of Adult Skills is a product of the Programme for the International Assessment of Adult Competencies (PIAAC) led by the Organisation for Economic Cooperation and Development (OECD). The Survey of Adult Skills aims to measure the skills needed by adults to participate in society and for economies to prosper. The 2023 survey assessed…

Quantitative reasoning is considered a crucial prerequisite for acquiring domain-specific expertise in higher education. To ascertain whether students are developing quantitative reasoning, validly assessing its development over the course of their studies is required. However, when measuring quantitative reasoning in an academic study program, it…

This study explores a pathway from social origin at adolescence to numeracy acquisition in young adulthood. A variation associated with vocational track attendance and numeracy acquisition between two different traditions of education systems is identified; namely, between education systems of German (Austria and Germany) and English (UK and US)…

Intelligence, as well as working memory and attention, affect the acquisition of mathematical competencies. This paper aimed to examine the influence of working memory and attention when taking different mathematical skills into account as a function of children's intellectual ability. Overall, intelligence, working memory, attention and numerical…

In mathematics education, there is general agreement regarding the significance of mathematical literacy (also quantitative literacy or numeracy) for informed citizenship, which often requires evaluating the use of numbers in public policy discourse. We hold that such an evaluation must accommodate the necessarily fragile relation between the…

Health-related decisions make use of numeracy skills, for example counting medication dosages, extracting health-related information from food packaging or understanding statistical data. Even though the concept of health literacy is often used to explain health disparities (Freedman et al., in American Journal of Preventive Medicine 36:446-451,…

Children's early numerical competencies are of great importance for later academic achievement. Young children gain these competencies in the context of the home numeracy environment (HNE). Additionally, child characteristics and families' socioeconomic status (SES) are associated with children's competencies. In this study, we investigated…

The present article connects a secondary analysis of quantitative data from the Programme for the International Assessment of Adult Competencies (PIAAC) with the theoretical approach of 'literacy practices' and related research results from the so-called New Literacy Studies (NLS) tradition, which follows a cultural practices paradigm. According…

"Practice engagement theory" (PET) posits that individuals' literacy proficiencies develop as a by-product of their engagement in everyday reading and writing practices and, reciprocally, that literacy proficiencies affect levels of engagement in reading and writing practices. This suggests that literacy training which increases…

This article explores cross-country patterns in how conditions relating to family background, education, and the labor market are related to literacy and numeracy skills. It seeks to assess whether these patterns are in agreement with models of skills formation as identified in the political economy literature. The novelty of this article resides…

This study advances the analysis of cognitive skill use at work by considering another crucial factor: the motivation-to-learn (MtL). Previous research has indicated that MtL forms cognitive skills in the school setting. However, the role of MtL in the work setting is much less understood. The present study analyses the association between MtL and…

Research on teacher knowledge has been criticised for taking too narrow a view on expertise. Therefore, teacher competence frameworks have been developed that are closely related to professional demands. Their practice-oriented conceptualisations have led to innovative measures with situative demands. However, there is still a lack of knowledge on…
