The following survey study uses a quantitative research design to investigate motivational and affective aspects of students (aged 14-17) in a mathematical workshop on graph theory. Motivational and affective aspects are related to heart rate measurement (using the digital medium of a pulse watch) in mathematical knowledge development processes in…

For biology students, the diversity, complexity, and abundance of content in this field yield a heavy study load. Hence, appropriate learning strategies are key in supporting learners' academic success. In biology, the factors gender and interest hold a unique position within the natural sciences, as there is an academic imbalance to the…

In order to cope with the COVID-19 pandemic, many schools have been closed for several months as of March 2020 in Germany. The unplanned and rapid shift to distance learning formats has led to fears that extensive learning deficits will be created and educational inequality will be further exacerbated. This paper, therefore, investigates the…

The aim of the current study was to investigate the relationship between adolescents' social support, their internalising and externalising behaviour problems, and their alcohol consumption. Adolescents attending Grade 7-10 (N = 329), answered questionnaires regarding their perceived social support (from parents, teachers, classmates, and…

The aim of the current study was to investigate whether the association between parental attachment and externalizing behavior is parallelly mediated by dysfunctional emotion regulation and callous-unemotional traits. The community sample included 296 adolescents (M[subscript age]?=?14.90, SD[subscript age]?=?1.31), who completed the Inventory of…

This study investigates students' conceptions of the carbon cycle with regard to the components they believe to be relevant to the carbon cycle, how they interrelate these components, the ways in which they trace carbon atoms, and the different levels of biological organisation they consider when doing so. A total of 142 students aged 13-16 years…

Participation in science is unevenly distributed among secondary school students, depending on gender, social class, and ethnicity. In the present study, the influence of the home environment on students' chemistry self-concept is investigated as a factor for explaining participation in science. For this, the sociological lens of chemistry capital…

In this study with 153 middle school students, we investigate the influence of the number of decimal places from the reading of a measurement device on students' decisions to change or keep an initial hypothesis about falling objects. Participants were divided into three groups, introduced to two experiments--the time it takes a free falling…

Background: This article describes the design and the evaluation of a student lab program on the topic of nanoscience and technology (NST), mainly focusing on Nanoscience and its applications. The program was designed for students in grades 8-10 and was part of a larger outreach program of the Collaborative Research Center 'Function by Switching'…

Theories of creativity and empirical evidence have highlighted the importance of autonomy as a motivational source of creativity. However, we know little about the relationship between the implicit autonomy motive and creativity. Using a multi-method multi-informant design, we investigated the relationship between implicit autonomy motives and…

Competitions are discussed as a measure to foster students' interest, especially for highly gifted and talented students. In the current study, participants of a cognitive school competition in science were compared to non-participants of the same age group (14-15) who either did not participate in any competition or who participated in a…

This mixed-methods cross-national study investigated the effectiveness of reality pedagogy (an approach in which teachers become part of students' activities, practices and rituals) in terms of changes in student perceptions of their learning environment and attitudes towards science. A questionnaire was administered to 142 students in grades 8-10…

Results of the last thirty years in mathematics education have shown the importance of an operational concept development. One of the geometrical concepts that has been researched for years already, however, not with the particular focus on its systematic teaching in school mathematics, is the concept of angle. In this paper we focus on children's…

In Germany, adolescents with emotional and behavioural disturbances (EBD) are either schooled in special schools for students with EBD or in regular schools. The present study is the first to compare the perceived attainment of a broad range of developmental tasks of adolescents with and without EBD attending regular vs. special schools. While…

The relevance of environmental attitudes is obvious and attitudes towards farm and companion animals and animal welfare in medical research are an important aspect of education. However, both have rarely been linked with each other, and animal attitudes are only sparsely represented within environmental education assessment instruments. Linking…
