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…

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…

Studies on math learning programs are lacking that consider a wide set of outcome variables, and students' practice behavior. Therefore, we investigated whether an adaptive arithmetic learning program fosters students' math performance (addition and subtraction), math self-concept, and a reduction of math anxiety, and how practice behavior…

German primary school students' reading skills have declined between 2016 and 2021, with a deficit of up to one third of a school year. The most significant portion of the decline is attributed to the COVID-19 pandemic experiences. These delays are critical because children have to catch up on skills and knowledge they should already have while…

To examine developmental processes, intervention effects, or both, longitudinal studies often aim to include measurement intervals that are equally spaced for all participants. In reality, however, this goal is hardly ever met. Although different approaches have been proposed to deal with this issue, few studies have investigated the potential…

Mathematical arguments are central components of mathematics and play a role in certain types of modelling of potential mathematical giftedness. However, particular characteristics of arguments are interpreted differently in the context of mathematical giftedness. Some models of giftedness see no connection, whereas other models consider the…

The aim of the current investigation was to compare the association between attachment and behaviour problems in children attending regular schools and children attending special education schools with a focus on emotional and social development. We draw upon data collected from 169 children attending regular schools (M[subscript age] = 9.66), and…

This paper presents evidence how pupils choose different types of non-monetary rewards for educational attainment. These rewards are external to the learning process, but unlike cash-for-grades rewards internal to the practice of schooling. We collected data from a non-incentivized survey and an incentivized survey, which was part of a larger…

The increasing number of students with German as a second language (GL2) poses a great challenge for schools. Previous studies showed that especially young learners with a migration background are lagging behind in the acquisition of second language (L2) literacy. Experiencing problem behaviors (PB) in addition, might pose even greater challenges.…

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 current study evaluates effects of teaching factors and extended day programs regarding both average achievement and socioeconomic achievement gaps. Analyses are based on data from the National Educational Panel Study in Germany. The sample comprises 1523 students in 120 classes in 71 secondary schools. The investigation period covers fifth…

Deficits in phonological information processing in upper elementary students with specific learning disabilities in reading or spelling may increase, decrease, or remain stable over time. The authors examined the development of phonological processing longitudinally in 209 students (109 with learning disabilities and 100 typically achieving;…

This study examines the effects of a working memory (WM) sensitive math intervention in students with learning disabilities (LD). The intervention aims to improve early mathematical competencies while accounting for weak cognitive resources through a reduced instructional design. These principles are considered to be effective for learning. Ten…

Reading comprehension is a fundamental and indispensable skill for academic achievement and daily functioning. Sadly, a significant number of children and youth, particularly those diagnosed with learning disabilities (LD), encounter difficulties in acquiring this vital capability. Thankfully, several well-established approaches exist to offer…

In a design-research project on problem-solving, theory-based and practice-oriented materials were developed with the goal of fostering systematical development of students' problem-solving competence in a targeted manner by learning heuristics. Special attention was given to working backward strategy, which has been shown difficult for students…
