Although an average of one to two children per classroom suffer from ADHD, empirically supported classroom interventions are not yet implemented possibly because of teachers' lack of knowledge or negative attitude towards them. To investigate this science-practitioner gap, we need an instrument assessing knowledge, attitude and the use of…

To reduce nonresponse bias in surveys, it has been suggested that researchers allocate additional fieldwork efforts to cases with low estimated response propensity. If these efforts are successful, nonresponse bias may be reduced by changing the variance of response propensities and hence the covariance between response propensities and variables…

The number of foreign languages spoken in Germany is rising, and as a result German is increasingly being learned as a second language (L2). This is a challenge for many secondary-school students, especially those who have learning disabilities (LD) and behavioral difficulties, which are often accompanied by reduced motivation to learn, in this…

This study examines the relationships between the environmental attitudes and environmental knowledge of school children within the framework of an environmental intervention. We employed questions from the 2-MEV model to monitor students' environmental attitudes in terms of the model factors Preservation and Utilisation while concurrently…

Background: Research on test anxiety of elementary school children has mainly focused on prevalence rates and gender differences. Less work has addressed predictors of test anxiety in elementary school children. According to the control-value theory developed by Pekrun ("Educ Psychol Rev" 18:315-341. doi: 10.1007/s10648-006-9029-9,…

Background: Diabetes self-management education (DSME) is generally considered to be a key determinant of the treatment outcomes and related costs of diabetes mellitus. While DSME programmes generally have positive outcomes, their effects may depend on certain factors, such as the type of programmes provided and patients' level of health literacy…

Students participate during service learning courses in a service project, which fits to a community need and has a link to curricular content. Students have a chance while engaged in the service project to apply curricular content in community practice, where they gain insights into civic engagement activities. Empirical studies revealed the…

Dyslexia in consistent orthographies like German is characterized by dysfluent reading, which is often assumed to result from failure to build up an orthographic lexicon and overreliance on decoding. However, earlier evidence indicates effects of lexical processing at least in some German dyslexic readers. We investigated variations in reading…

Background: Adolescent depression has been recognized as a complex problem that presents a global public health challenge. Left undetected and untreated, depression can significantly reduce quality of life. Objective: The main purpose of this paper is to re-visit risk and protective factors for depression in adolescents with a specific focus on…

Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent psychiatric disorder in adolescence and results severe impairment. Few psychosocial interventions aim at ADHD in adolescence and are rarely evaluated in randomized controlled trials (RCTs). Therefore, an intervention combining adolescent-directed problem-solving and…

Using a cluster randomized field trial, the present study tested whether 2 relevance interventions affected students' value beliefs, self-concept, and effort in math differently depending on family background (socioeconomic status, family interest (FI), and parental utility value). Eighty-two classrooms were randomly assigned to either 1 of 2…

Systems' thinking has become increasingly relevant not only in education for sustainable development but also in everyday life. Even if teachers know the dynamics and complexity of living systems in biology and geography, they might not be able to effectively explain it to students. Teachers need an understanding of systems and their behaviour…

Purpose: The purpose of this paper is twofold: first, to introduce MEDIA PROTECT, a multi-modal intervention for parents and teachers with six components preventing problematic, and in the long run addictive, use of screen media by children; second, to present results of a formative evaluation of the teacher training, an important component of the…

Background: Science Olympiads and science fairs are effective instruments to foster interested and talented students. However, at most schools competitions are not systematically integrated into the school mission statement so that students are unaware of these opportunities. Purpose: The purpose of this study was to investigate the effectiveness…

Nonsuicidal self-injury (NSSI) and suicidality are common among adolescents. School staff are often the first adults to be confronted with those behaviors. However, previous studies have shown a lack of knowledge and confidence in dealing with self-harming behaviors. Objectives of this study were to evaluate a workshop on NSSI and suicidality in…
