Interdisciplinary research is a popular mode of knowledge production that becomes intensively promoted by research centers all across the globe. Despite the facilitation of interdisciplinary research, however, scholars working in these centers are 'disciplined.' Career promotions, funding decisions and scientific publishing are based on…

The governance of Vocational Education and Training (VET) systems in Germany and Switzerland is determined by a constellation of actors that has grown over many years. This constellation has long-term elements and at the same time it is a flexible system that is subject to constant pressure to change, just like the economic and social structures…

To examine the factor structure of autism spectrum disorder (ASD) and the psychometric properties of the German Symptom Checklist for Autism Spectrum Disorders (SCL-ASD). Data were collected from 312 clinical referrals with suspected ASD (2-18 years). Confirmatory factor analyses and analyses of reliability, convergent and divergent validity were…

How is it possible to create and continuously improve a quality learning environment for our students? We present our one-year course on engineering thermodynamics as a case study in which we investigate the learning environment based on a competency model from the students' perspective. Based on the analysis of our course structure and exam…

Research and practice have recognized the importance of informal learning--a specific type of active learning--for higher education contexts. University students learn not only in formally organized courses, but also in a self-directed and intentional way from fellow students, through trial and error, and by reflection. However, there has been a…

The Student Background survey administered along with achievement tests in studies of the International Association for the Evaluation of Educational Achievement includes scales of student motivation, competence, and attitudes toward mathematics and science. The scales consist of positively- and negatively keyed items. The current research…

The paper describes the concept of a federated ecosystem for Open Educational Resources (OER) in the German education system. Here, a variety of OER repositories (ROER) (Muuß-Merholz & Schaumburg, 2014) and reference platforms have been established in the recent past. In order to develop this ecosystem, not only are metadata standards…

Due the wideness of the term Physical Computing, there is a need for a better structure of this topic. This paper is about an approach of structuring this field by finding attributes of different physical computing devices which can be used in class. Those attributes are meant to enforce teachers as well as researchers to analyze different devices…

Given the controversies surrounding the critical period hypothesis on second-language (L2) learning outcomes, this study focuses on the phonological aspect of language acquisition--the strength of the foreign accent in L2. Drawing on data from a large-scale representative data set on immigrant adolescents in Germany--CILS4EU-DE--we first…

Newtonian mechanics is still among the most difficult topics in the physics' syllabus taught at school. For example, even after completing traditional instruction, students still think that a force is necessary to maintain motion. Therefore, a revised method of instruction is needed that meets students' learning needs. The aim of the project…

Despite increasing data on young children's patterning skills and evidence of a link between early pattern knowledge and later mathematics performance, little is known about the strategies children use to solve patterning tasks. This mixed-methods study examined 3- to 5-year-old children's informal strategies when solving eight patterning tasks…

Purpose: One of the central questions in speech production research is to what degree certain structures have an inherent difficulty and to what degree repeated encounter and practice make them easier to process. The goal of this article was to determine the extent to which frequency and sonority distance of consonant clusters predict production…

We investigated by means of a simulation study how well methods for factor rotation can identify a two-facet simple structure. Samples were generated from orthogonal and oblique two-facet population factor models with 4 (2 factors per facet) to 12 factors (6 factors per facet). Samples drawn from orthogonal populations were submitted to factor…

Social, emotional, and behavioral (SEB) skills comprise a broad set of abilities that are essential for building and maintaining relationships, regulating emotions, selecting and pursuing goals, or exploring novel stimuli. Toward an improved SEB skill assessment, Soto and colleagues recently introduced the Behavioral, Emotional, and Social Skills…

Purpose: Treating Active Citizenship as a sum of behavioral indicators requires certain prerequisites that can be difficult to meet in practice (e.g. structural validity and measurement invariance). We explore a different approach, in which we treat Active Citizenship as a categorical, rather than a linear, construct. Design: Based on longitudinal…
