Theoretical background: Learning in virtual realities (VR) has become increasingly important. In this context, VR appears to be particularly conducive to affective learning objectives, such as perspective-taking in VR actors. Previous research has often focused on investigating cause-effect relationships that focus on the direct effects of…

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…

This paper provides a critical review of indicators that can be used to measure equity in educational outcomes. These indicators are evaluated using different criteria. Further, analysis on how the sample structure affects equity measurements is undertaken. Analyses are based on theoretical reasoning and empirical data from the German National…

Control-value theory (CVT) proposes a framework for the structure of the relationships between the various predictors of achievement-related emotions, particularly anxiety. Despite existing evidence for the role of anxiety predictors, research has not yet justified their proposed structure. Hence, the current study validated the structure of test…

Sculpting representations of human organs out of modeling clay is an acknowledged method of teaching anatomical structures. Because of its potential to provide detailed spatial information, stereoscopic imagery can be understood to function as a suitable template for such sculpting tasks. Currently, it is unknown whether the advantages of…

Empirical analysis of secondary biology classrooms revealed that, on average, 68% of teaching time in Germany revolved around processing tasks. Quality of instruction can thus be assessed by analyzing the quality of tasks used in classroom discourse. This quasi-experimental study analyzed how teachers used tasks in 38 videotaped biology lessons…

This study is a substantive-methodological synergy in which exploratory structural equation modeling is applied to investigate the factor structure of multidimensional self-concept instruments. On the basis of a sample of German students (N = 1958) who completed the Self-Description Questionnaire I and the Self-Perception Profile for Children, the…

This paper describes the second in a series of studies exploring the acceptance of the subatomic structure of matter by 12-year-olds. The studies focus on a novel learning unit introducing an atomic model from electrons down to quarks, which is aimed to be used at an early stage in the physics curriculum. Three features are fundamental to the…

Background: After elementary school, students in Germany are separated into different school tracks (i.e., school types) with the aim of creating homogeneous student groups in secondary school. Consequently, the development of students' reading achievement diverges across school types. Findings on this achievement gap have been criticized as…

[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] Developing a solid understanding of simple electric circuits represents a major challenge to most students in middle school. In particular, students tend to reason exclusively with current and resistance when analyzing electric circuits as they view…

Previous analyses of German geography textbooks confirm tendencies towards the moralization of sustainability-related content. Against this background, this study examines moralizations and normative implications of recurring sustainability narratives in German textbooks for secondary schools. From the sample of 15 current middle school textbooks…

Academic self-concept has been conceptualized as a multidimensional and hierarchical construct. Previous research has mostly focused on its multidimensionality, distinguishing between verbal and mathematical self-concept domains, and only a few studies have examined the factorial structure within specific self-concept domains. The present study…

Given the key role of conversions of representations for mathematical understanding, it is highly relevant to investigate in detail competencies regarding conversions of representations. In particular, a corresponding competence model should not only be developed theoretically, but also examined empirically. However, such empirical studies are…

Motivated by discussions of skill mismatches on local German vocational educational and training (VET) markets, this paper analyses how occupational segments of VET entry of individuals with lower and intermediate secondary school degree relate to local labor market characteristics. The econometric analysis applies data from a survey conducted…

Academic self-concept and achievement have been found to be reciprocally related across time. However, existing research has focused on self-concept and achievement scores that have been averaged over long time-periods. For the first time, the present study examined intraindividual (within-person) relations between momentary (state) self-concept…
