Based on the relationships motivation theory, it can be assumed that social interactions in elementary school are essential for students' development and especially for their school success. Thus, this study examined how vital social resources, more precisely social interactions with peers and teachers, are for two central aspects of school…

Trend results from the Progress in International Reading Literacy Study (PIRLS) show a decline from 2001 through 2016 in most countries in fourth graders' and their parents' reading attitudes, as measured by students like reading and parents like reading scale scores. Average students like reading scale scores, as reported by the students…

In studies of academic resilience, the concept is typically operationalized by pre-defined cutoff values of students' achievement level and their social background. A threat to the validity of such arbitrary operationalizations is that students around the cutoff values may be misclassified. The main objective of the current study is to apply a…

Research on reading achievement and reading motivation has rarely addressed the question if and how they affect each other over time. In our study, we investigate the reciprocal effects between reading achievement and both intrinsic and extrinsic reading motivation during elementary school. We measured reading achievement and intrinsic and…

Previous research has shown that parental involvement at home seems to be socio-economically stratified. To study this stratification, recent research has drawn a distinction between early and late parental literacy activities at home. Early parental literacy activities at home happen before primary school, whereas late parental literacy…

Developmental Coordination Disorder (DCD) and Attention Deficit Hyperactivity Disorder (ADHD) often co-occur and are associated with specific learning difficulties. Robust prevalence estimations do not yet exist. We studied how symptoms of DCD and/or ADHD are related to difficulties in reading, writing, and mathematics. Using the data from a large…

Academic resilience is difficult to define in an international setting, since economic levels and achievement standards vary across countries and over time. In studies of academic resilience, the concept is typically operationalized using pre-defined cut-offs of achievement and social background. The main objective of the current study is to apply…

This study investigates consistent and inconsistent respondents to mixed-worded questionnaire scales in large-scale assessments. Mixed-worded scales contain both positively and negatively worded items and are universally applied in different survey and content areas. Due to the changing wording, these scales require a more careful reading and…

The association between academic self-concept and achievement is assumed to be reciprocal. Typically, the association is analyzed by variants of the classical cross-lagged panel model. Results with more recently developed methodological approaches, for example, the random intercept cross-lagged panel model, its continuous-time implementation, and…

It is well-documented that academic achievement is associated with students' self-perceptions of their academic abilities, that is, their academic self-concepts. However, low-achieving students may apply self-protective strategies to maintain a favorable academic self-concept when evaluating their academic abilities. Consequently, the relation…

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the…

Regarding research on inclusive education, it is unknown whether differences in classroom composition provide unequal opportunities for educational outcomes of students with special educational needs (SEN). We investigated effects of student characteristics and classroom composition on reading achievement and social participation of SEN students.…

The Student Background survey administered along with achievement tests in studies of the International Association for the Evaluation of Educational Achievement includes scales of student motivation, competence, and attitudes toward mathematics and science. The scales consist of positively- and negatively keyed items. The current research…

The aim of the present study was to investigate the associations between parental and teacher support and elementary students' academic skills during the COVID-19 pandemic. Building on data of an ongoing longitudinal study, we studied the roles of children's (N = 63) academic skills before the first COVID-19 lockdown in Germany (March-June 2020)…

PIRLS (Progress in International Reading Literacy Study) is the fourth assessment in the current trend series, following PIRLS 2001, 2006, and 2011. There were 61 participants in PIRLS 2016, including 50 countries and 11 benchmarking entities (e.g., regions of countries as well as additional grades or language groups from the participating…
