Abstract
Abstract null null This study aims to investigate how test scores from PIAAC (Programme for the International Assessment of Adult Competencies) can be interpreted, by comparing the PIAAC competencies literacy and numeracy to reasoning and perceptual speed. Dimensionality analyses supported, that the PIAAC competencies can be separated into a common factor overlapping with reasoning and perceptual speed, and domain-specific factors. For the common and specific factors, relations to other variables were analyzed. The nested factor for PIAAC literacy was as expected unrelated to age, positively related to learning opportunities during one’s lifetime, and positively related to literacy skill use. The nested factor for PIAAC numeracy was also as expected unrelated to age, against expectation unrelated to learning opportunities during one’s lifetime, and as expected positively related to numeracy skill use. Results support the validity of the intended test score interpretation for PIAAC literacy, while results for PIAAC numeracy were less clear.

ABSTRACTThe purpose of the present study was to examine the relationship between reading literacy and age in an adult population aged 25 to 65 in Nordic countries using PIAAC 2012 data. More specifically, the study examined to what extent variations in the literacy proficiency of adults are explained by age and the recentness of qualifications when variables related to education, occupation, and skill use are controlled. The statistical method was regression analysis. The recentness of education...

The bifactor model is a widely applied model to analyze general and specific abilities. Extensions of bifactor models additionally include criterion variables. In such extended bifactor models, the general and specific factors can be correlated with criterion variables. Moreover, the influence of general and specific factors on criterion variables can be scrutinized in latent multiple regression models that are built on bifactor measurement models. This study employs an extended bifactor model t...

Intelligence test scores and educational duration are positively correlated. This correlation could be interpreted in two ways: Students with greater propensity for intelligence go on to complete more education, or a longer education increases intelligence. We meta-analyzed three categories of quasiexperimental studies of educational effects on intelligence: those estimating education-intelligence associations after controlling for earlier intelligence, those using compulsory schooling policy ch...

International large-scale assessments are on the rise, with the Programme for International Student Assessment (PISA) seen by many as having strategic prominence in education policy debates. The present article reviews PISA-related English-language peer-reviewed articles from the programme’s first cycle in 2000 to its most current in 2015. Five literature bases were searched, and results were analysed with SPSS. Results map the frequency of publications according to journal, country, and scienti...

Abstract Computer-based assessments open up new possibilities to measure constructs in authentic settings. They are especially promising to measure 21st century skills, as for instance information and communication technologies (ICT) skills. Items tapping such constructs may be diverse regarding design principles and content and thus form a heterogeneous item set. Existing validation approaches, as the construct representation approach by Embretson (1983), however, require homogenous item sets i...

This study investigates the interplay between general cognitive abilities and domain-specific mathematical ability by applying three different models. The first model is a g factor model, the second model reflects two correlated factors, and the third model is a nested-factor model that comprises a g factor, a domain-specific mathematical factor and cognitive ability. Furthermore, we analyzed the relation between student characteristics such as self-concept in mathematics, gender, SES, and grade...

Abstract Ability grouping or tracking during secondary schooling is widespread. Previous research shows academic track schools are more successful than non-academic track schools in teaching mathematics, reading and foreign languages. Reasons include a more favorable student composition and higher instructional quality. However, there is less evidence that between track differences are even large enough to differentially affect the students' cognitive development. We used data from a large Hambu...

The present paper investigates the power of personality to predict important life outcomes in the context of the Programme for the International Assessment of Adult Competencies (PIAAC). On the most global level, personality can be described by the Big Five dimensions, extraversion, agreeableness, conscientiousness, emotional stability, and openness to experience. These five dimensions were assessed in the German PIAAC longitudinal study (N = 4122) and can thus be directly related to the central...
