Measurement estimation skills are relevant for our everyday life and should be addressed in the mathematics classroom. Although students' measurement estimation skills were examined in several empirical studies, a structure model to describe these skills is still missing. The current research aimed at analyzing the structure of length estimation…

Discrepancies among family members' ratings on aspects of family functioning are challenging both, methodological and interpretational. Family members' perspectives and their discrepancies are indicators of family functioning, affecting adolescents' psychological development. Previous research focused on linear effects, ignoring that rather…

Inquiry-based science instruction has been proposed as an optimal learning environment for language-integrated teaching. While its potential for developing both content knowledge and language skills has been shown for students with limited language proficiency, research focusing on mainstream classrooms has mainly considered domain-specific…

By focusing on 179 elementary school children, the present cross-sectional questionnaire study aimed to examine gender and immigrant-native differences in competence and affect self-concepts as well as academic achievement and the relations of those two self-concept components to academic achievement in the domains of mathematics and German.…

Learning strategies can be powerful learning tools. Some studies show that even primary school students use them. However, hardly any studies have investigated the use of learning strategies of students with special needs, especially for those with emotional and behavioural disorders, in primary schools. Thus, in the present study we examined…

Mathematical arguments are central components of mathematics and play a role in certain types of modelling of potential mathematical giftedness. However, particular characteristics of arguments are interpreted differently in the context of mathematical giftedness. Some models of giftedness see no connection, whereas other models consider the…

The increasing number of students who lack proficient reading skills is well known in Germany, as well as globally. Students with learning disabilities (LD), problem behavior, and German as a second language (L2) may face even greater hurdles. However, it is essential for teachers to provide adequate support to maintain equal educational…

The aim of the current investigation was to compare the association between attachment and behaviour problems in children attending regular schools and children attending special education schools with a focus on emotional and social development. We draw upon data collected from 169 children attending regular schools (M[subscript age] = 9.66), and…

The increasing number of students with German as a second language (GL2) poses a great challenge for schools. Previous studies showed that especially young learners with a migration background are lagging behind in the acquisition of second language (L2) literacy. Experiencing problem behaviors (PB) in addition, might pose even greater challenges.…

Achievement emotions have received increasing attention in research on adolescence and young adulthood, but little is known about these emotions in the early years of schooling. Studies addressing the development of different achievement emotions and their linkages with achievement during these years are largely lacking. The present longitudinal…

Mathematics difficulties (MD) affect about 20% of the students in German schools. Almost half of them also exhibit emotional and behavioral difficulties (EBD). While a growing number of mathematics interventions target children with MD separately, there is a lack of evidence for the effectiveness of these interventions for children with combined…

Deficits in phonological information processing in upper elementary students with specific learning disabilities in reading or spelling may increase, decrease, or remain stable over time. The authors examined the development of phonological processing longitudinally in 209 students (109 with learning disabilities and 100 typically achieving;…

This study examines the effects of a working memory (WM) sensitive math intervention in students with learning disabilities (LD). The intervention aims to improve early mathematical competencies while accounting for weak cognitive resources through a reduced instructional design. These principles are considered to be effective for learning. Ten…

Children's positive perceived motor competence (PMC) provides motivation for physical activity. Theoretically young children (<8 years) have inflated PMC but as children cognitively develop, perceptions are hypothesized to decrease. This study investigated strength of PMC association over time, whether any change was negative (i.e. PMC…

Reading is a fundamental academic skill and influences numerous outcomes throughout lifespan. Unfortunately, many German students struggle with basic reading. Specifically, students with Learning Disabilities (LD) and Emotional Behavioural Disorders (EBD) encounter major hurdles. Consequently, insufficient reading achievement and concomitant…
