Previous studies differed largely in their findings concerning the relationship between principal leadership and students' mathematics achievement because of the complexity of principal leadership. As Hallinger and Heck's theoretical framework showed, principal leadership was comprised setting vision/goal, school management, and school climate…

The few studies about whether parents' implicit theories about ability (ITs) predict their children's academic success and relevant parental behavior have produced mixed results. In response, research suggested that parents' ITs might be more important in contexts that make children's intellectual potential salient. Therefore, we investigated the…

The main objective of this study was to investigate 9-10-year-old children's comprehension processes during listening to and free recall of a story. A cross-linguistic design comprised texts in L1 German and recall in L2 English and vice versa. Corresponding mono-linguistic control conditions in either L1 or L2 allowed to examine the extent to…

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…

Due to the increasing educational use of the Internet, children in elementary school need to critically evaluate source information to judge the trustworthiness of information. Studies with adult readers show that sourcing prompts and mutually exclusive claims in reading materials promote the use of source information. However, little is known…

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…

Do expansive body postures increase self-esteem in children? Power posing is a popular but also controversial topic. Still, there has been no research on the possible effects in children. To investigate the influence of power posing in children, 108 German fourth graders were randomly assigned to a high versus a low power posing group. Self-esteem…

This study explored the relationship between educational technology and the mathematics achievement of South African and German students. Hierarchical Linear Models (HLM) showed that the availability of computers at school and using computers in the mathematics classroom in South Africa positively associated with the mathematics achievement of…

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…

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…

The purpose of this experiment was to determine the effects of a simultaneous prompting procedure on the writing performance of three upper-elementary-level students diagnosed with learning disabilities (LD). Interventionists gave task directions followed by model prompts with a 0-s time delay to teach students composition. Non-targeted…

One challenge of child-computer interaction research is surveying variation of children's attitudes towards novel educational technology, which often results in an opinion ceiling effect. In this article, the authors introduce BiCo -- a bipolar continuous rating scale which builds on children's ability to draw relative comparisons. They elaborate…

Direct Behavior Rating (DBR) has been proposed as a promising approach to assess student behavioral progress in classroom settings. The current study examines raters and occasions as well as their interactions as sources of error in the use of DBR--Multi-Item Scales (DBR-MIS) and DBR--Single-Item Scales (DBR-SIS) for academically engaged (AE) 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…

Research has shown that a profound place value understanding is crucial for success in learning mathematics. At the same time, a substantial number of students struggles with developing a sustainable place value understanding. In this regard, two aspects of the place value system appear especially relevant: First, the knowledge of the decimal…
