Purpose: Unhealthy eating among adolescents from families with lower social status is a major concern. The purpose of this paper is to describe the development and evaluation of a prototype-targeting intervention for the promotion of healthy eating in this target group. Design/methodology/approach: The planning model intervention mapping (IM) was…

Proper understanding of and learning from physics phenomena and experiments requires--among other competencies--flexible and coherent use of multiple representations (MRs). These can include everything from the "enactive" or "operational" manipulation of the experimental devices and materials to the most abstract level of a…

Pedagogical content knowledge forms the core of teachers' professional knowledge; it refers to knowledge about making subject matter accessible to students. Thus, the formation of pedagogical content knowledge constitutes a crucial issue for educational research and practice. We investigated the contributions of content knowledge and pedagogical…

Achievements in various fields of creativity are resulting more and more from collaborative teams. This research investigated the role of interpersonal process variables, namely closeness and perspective taking in group creativity, with a 2 by 2 experimental design. Sixty-one 3-person groups assigned to 4 conditions (a: closeness and perspective…

The present study aims to empiricaly demonstrate the viability and benefits of an awareness-based approach to diversify knowledge between potential learning partners. Groups of four learners studied lesson material on biology. After a knowledge test, the groups were to form collaborative learning dyads. Based on the test, a novel knowledge…

The aim of the current study was to investigate the impact of private tutoring on parental involvement and the parent-child relationship. Seventy-six students voluntarily participated in the longitudinal study (38 students newly signed up for private tutoring and a matched control group). Data were collected with a student questionnaire that was…

Digital transformation has opened novel opportunities for educators to approach the challenges of educating tomorrow's business leaders and managers. New methods of instruction such as blended learning and e-learning allow to cater better to a generation of digital natives and to enhance their learning ability. In the fast-moving business world,…

This article argues that multisentence discourses give rise to Gricean quantity implicatures that go beyond the mere sum of the implicatures of the sentences they consist of. We formulate two theories of discourse-level implicature: the null theory, which only has a mechanism for sentence-level implicature and does not rely on any specific notion…

Children who do not adequately master the transition from "learning to read" (LTR) to "reading to learn" (RTL) will clearly fall behind in every subject area during their secondary education. The purpose of this study was to determine whether a simple reading comprehension strategy developed by Schumaker, Denton, and Deshler…

We examine whether German children attach an adultlike relevance to the pragmatic category of polarity contrast (e.g., "In my picture the child IS eating the candies" following after "In my picture the child is not eating the candies") with linguistic expressions (i.e., the affirmative particles…

Although creativity techniques are highly recommended in working environments, their effects have been scarcely investigated. Two cognitive processes are often considered to foster creative potential and are, therefore, taken as a basis for creativity techniques: knowledge activation and conceptual combination. In this study, both processes were…

The motivation to engage in a task is directly related to its perceived value according to Deci & Ryan (1985). Increasing motivation can lead to a higher enhanced learning achievement for the student. The question is if using digital technologies in inquiry-based learning lessons influences the learners' situationally perceived value of the…

A long delay between the first registered symptoms of autism spectrum disorder and a final diagnosis has been reported. The reasons for this are the spare use of specialized autism instruments, missing clinical expertise, and the late referral to specialized centers in primary care. Previous studies recommending the Child Behavior Checklist 1.5-5…

Bullying against lesbian and gay adolescents continues to be a problem in Western societies. Interventions to reduce homonegative attitudes could help to address bullying. We evaluated the effectiveness of a workshop against homonegativity in adolescents (N = 214) aged between 14 and 16 years in a pretest, posttest, follow-up design with a control…

Decorative pictures, which make a learning text aesthetically appealing rather than provide information, have been predominantly found to impair learning by an increase of learning-irrelevant cognitive processes. Recent research, however, indicates that this effect is moderated by various factors. On the basis of cognitive-affective theories and…
