The paper addresses concept formation processes of students in the field of geometry. More precisely, the paper deals with the questions of what knowledge do students activate about triangles in different contexts with different (digital) tools and furthermore what content-related meaning do they give to the concept of triangles? Methodologically,…

Research on the history of childhood faces fundamental challenges in tracing children's voices. Not yet skilled in forms of written self-documentation, children leave few documents behind. Other forms of expression (i.e. drawings) must thus be recognised as valuable historical sources and appropriate methods must be applied. These research…

General Studies (Sachunterricht) lesson, which includes social and science themes because of its interdisciplinary form, takes place in the curriculum of each class level at primary schools in Germany. The aim of this descriptive case study is to examine how the teaching process of third-grade General Studies lesson is run in terms of learning…

Primary education levels are called primary education, compulsory education, and public education. Nowadays, new research has shown that primary education plays an important role in the reduction of poverty and the realization of economic and social development programs.

The school context, like other influences, affects the development of students' epistemic beliefs (EBs), with theoretical conceptualizations suggesting a distinction between EBs related to professional and school science. However, empirical studies rarely address this distinction, and instruments separately assessing these EBs are not available.…

This paper aims to research practices of resistance as an important part of agency in primary school classrooms. By combining a post-structural theoretical frame with a critical ethnographic research approach, it understands children's resistance as an ordinary practice, as a necessary response to structures and practices of the classroom setting.…

Previous research findings indicate that young children from East Asia outperform their counterparts from Europe and North America on executive function (EF) tasks. However, very few cross-national studies have focused on EF development during middle childhood. The current study assessed the EF performance of 170 children in grades 2 and 4 from…

In this article, we present a qualitative investigation which was conducted as part of a project on school development in the field of multilingualism in Germany.

Purpose: From a psycholinguistic perspective, the quality of the stored word form in the phonological input lexicon, as well as its effective retrieval from the phonological output lexicon, is of great importance in lexical processing. This study aimed at gaining a deeper understanding of (a)typical word form processing in primary school children.…

Purpose: In youth, cross-sectional studies reported age differences in balance performance that were in favor of adolescents. Thus, trainability of balance performance might be different in children compared to adolescents. The purpose of this study was therefore to compare the effects of balance training (BT) on balance performance between…

Psychological safety is the shared belief that the team is safe for interpersonal risk-taking. Critical team events such as conflict and faultlines (hypothetical lines that split a team into subgroups) should impact psychological safety. Previous research has shown the benefits of task conflict on team outcomes under certain conditions and the…

The rise of cross-sectoral collaboration initiatives has been widely documented. While schools and third-sector organizations share important educational goals in these initiatives, the predictors of their identification with common goals have not been examined systemically to date. This article analyses predictors of common goal identification…

In two studies, we investigated the extent to which research using case vignettes of fictitious students is able to yield research results that are ecologically valid representations of teachers' assessments of students' educational achievement in their real classrooms. The type of assessment was teachers' tracking decisions from primary to…

The article examines how diverse semiotic resources are made available for explaining mathematical terms in a fifth-grade classroom. Situated within the methodological framework developed by conversation analysis and the analysis of embodiment-in-interaction, the study deals with two instances of a classroom episode in each of which participants…

This case study examines authentic speech acts by a German primary school teacher in the classroom context and the outdoor learning location of a forest. The study will compare the degree of linguistic immediacy or distance in these two contexts, respectively. Once a week, the class is doing "outdoor school" ["Draußenschule"]…
