Academic language and its associations with school success have been established in many prior studies. However, the scholarship lacks research on the mechanisms that constitute these relations. This study investigates the mediating role of motivational-­affective variables, specifically reading self-concept and reading enjoyment, in relations…

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…

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…

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…

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)…

Monitoring the learning progress of at-risk students positively affects learning growth. This study transfers the approach of learning progress assessment (LPA) to general education in Germany and investigates the effects of information about reading progress and additional teacher training on student achievement. Classes (n = 43) were assigned to…

The purpose of this study was to examine the technical adequacy of a computer-based assessment instrument which is based on hierarchical models of text comprehension for monitoring student reading progress following the Curriculum-Based Measurement (CBM) approach. At intervals of two weeks, 120 third-grade students finished eight CBM tests. To…
