In March 2018, metal construction kits were distributed to all elementary schools in Rhineland-Palatinate as part of the project called "Technikkiste" [translation from German: technology box] to promote STEM education. At the end of the year 2018, three more expansion sets followed. So far, no requests have been made to schools, even…

Mathematics instruction in primary school has been influenced by many policy changes and empirical findings in the previous two decades. Geometry lessons, in particular, were re-evaluated due to a paradigm change and, consequently, were attributed a new meaning within the mathematics curriculum worldwide. The present paper focuses on this paradigm…

Authority is a central issue for teachers and refers to the leadership relationship between teachers and pupils for the purpose of initiating learning. A review of the current state of research shows that the interplay between authority and social inequality has seldom been investigated to date. That is the starting point for the present…

Measurement estimation skills are relevant for our everyday life and should be addressed in the mathematics classroom. Although students' measurement estimation skills were examined in several empirical studies, a structure model to describe these skills is still missing. The current research aimed at analyzing the structure of length estimation…

Participation is one key element of inclusive education. While the inclusion rate in German schools is rising, little is known with regard to children's participation in this context. This study examines the participation of children with and without impairments at three inclusive primary schools in Bavaria. Cross-sectional data was collected in…

Our study aims to provide empirical evidence for and against the valid use of primary school students' ratings of three generic dimensions of teaching quality (classroom management, supportive climate, cognitive activation). We examine whether students discriminate between corresponding dimensions in different subjects, taking into account whether…

Inquiry-based science instruction has been proposed as an optimal learning environment for language-integrated teaching. While its potential for developing both content knowledge and language skills has been shown for students with limited language proficiency, research focusing on mainstream classrooms has mainly considered domain-specific…

The development of technology affects the use of learning media in primary schools. This research applies the method of a systematic review literature with the favored revealing things for orderly audits and meta-examination (preferred reporting items for systematic reviews and meta-analyses (PRISMA)) protocol. The research stages include…

Purpose: To improve school organisational performance and innovativeness, and meet diverse student needs, school leaders should be innovative, risk-takers and proactive, thus applying entrepreneurial practices/strategies and market mechanisms. This study aims to investigate, from a schoolteacher's perspective, the degree of entrepreneurial…

Students need to create mental models for different types of addition and subtraction situations in order to develop a broad and viable understanding of these operations. Although most students succeed when changing or combining sets, situations that demand a quantitative comparison of sets seem considerably more difficult in the first school…

Direct Behavior Rating (DBR) has been proposed as a promising approach to assess student behavioral progress in classroom settings. The current study examines raters and occasions as well as their interactions as sources of error in the use of DBR--Multi-Item Scales (DBR-MIS) and DBR--Single-Item Scales (DBR-SIS) for academically engaged (AE) and…

Having friends influences students' academic, socio-emotional as well as health development. Especially, students with special educational needs (SEN) are at a high risk to belong to the subgroup of students without friends in class. Within a sequential explanatory design, two study phases have been implemented in the present study. In phase 1, a…

Based on Honneth's recognition theory, this study aimed at investigating whether students with a migration background reported receiving less recognition from teachers than students without a migration background. Also, we explored whether such a difference contributed to explaining the disparity between the groups in reading achievement. To…

The purpose of this qualitative descriptive study was to explore how elementary school teachers in Germany described their experience with movement method with respect to students' mental health and stress levels. The theoretical framework was Ryan and Deci's self-determination theory. The two research questions were: How did elementary school…

We examined the structure of domain-specific academic science vocabulary, general academic vocabulary, and conceptual science knowledge and their impact on each other across two measurement points in a sample of 388 German third graders. Results show that the three constructs can be empirically differentiated. The high latent correlation between…
