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…

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…

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…

Stereotype threat (ST) is a potential explanation for inequalities in language competencies observed between students from different language backgrounds. Language competencies are an important prerequisite for educational success, wherefore the significance for investigation arises. While ST effects on achievement are empirically well documented,…

A better understanding of how distractor features influence the plausibility of distractors is essential for an efficient multiple-choice (MC) item construction in educational assessment. The plausibility of distractors has a major influence on the psychometric characteristics of MC items. Our analysis utilizes the nominal categories model to…

In line with the reciprocal internal/external frame of reference model (RI/E model), it is well-established that secondary school students generate domain-specific ability self-concepts by comparing their own performance in a domain socially (i.e., with others' performance in this domain) and dimensionally (i.e., with their own performance in…

Research has shown that a profound place value understanding is crucial for success in learning mathematics. At the same time, a substantial number of students struggles with developing a sustainable place value understanding. In this regard, two aspects of the place value system appear especially relevant: First, the knowledge of the decimal…

The perception and manipulation of spatial information are essential for mathematical learning, and research highlights gender differences in spatial abilities. The present study contributes to the question of whether these differences are evident at earlier ages and how they interact with task complexity in mental rotation. We developed the…

Teachers play a key role in the development of self-regulated learning (SRL), especially in primary education. However, current results indicate that teachers are either inadequately or only moderately fulfilling this key function, as they spend little time in the instruction of SRL strategies. The objective of the current study was, therefore, to…

Background: Further developing students' thinking about knowledge and knowing in science (epistemic beliefs) is considered a normative goal of science education in many countries around the world, even for elementary-school-aged children. Aims: The goal of the present study was to introduce and evaluate a new intervention in science education…

Previous research on the role of prior skills like proportional reasoning skills for the development of mathematical concepts offers conclusions such as "more (prior skills) is better (for later learning)." Insights, which prior skill "level" goes along with which "level" of learning outcomes, may advance the…

Based on the relationships motivation theory, it can be assumed that social interactions in elementary school are essential for students' development and especially for their school success. Thus, this study examined how vital social resources, more precisely social interactions with peers and teachers, are for two central aspects of school…

This study investigates students' motivation during experimentation in geography lessons by implementing a newly developed experimental kit on soils (GeoBox) in Germany. The study focuses on a first evaluation by means of a one-group pretest/posttest design. Fifth-grade students (N = 166) answered a questionnaire pertaining to regular geography…
