This paper presents a replication study investigating the effectiveness of a strategy to assist students with learning difficulties in adding fractions. Drawing on the research conducted by Grünke et al. (2023), this single-case analysis extends the application of the "Look, Ask, Pick" (LAP) mnemonic technique initially introduced by…

To promote pro-environmental behavior (PEB), it is crucial to understand the drivers behind it. Studies indicate that, in addition to environmental attitudes and nature activities, interest in nature drives people to engage in PEB. However, the relationship between interest in nature and PEB is still greatly understudied among adolescents even…

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…

Fractions are an integral part of the mathematics curriculum. Most students acquire proficiency with these concepts during the course of their elementary education and are usually able to perform basic fractions operations when reaching middle-school age. However, a considerable number of students require extra help to not fall further and further…

By complying with their "job", i.e., completing the tasks set for them by teachers, pupils develop their subject skills. They do this in a classroom setting where they can perceive each other regarding their abilities. Besides content learning, pupils, thus, also have to position themselves emotionally and action-practically towards the…

Experiments are an important way of working in the geography classroom. They promote and require numerous geographic skills. At the same time, experiments are only used comparatively rarely in geography lessons in Germany. In order to increase the frequency of experiments in the classroom and to better exploit their potential, GeoBoxes have been…

Previous studies show that girls have a lower scientific self-concept than boys. Since interest starts declining over the course of lower secondary school, this exacerbates the issue that fewer girls aspire to choose a scientific profession. In this article, we present the concept of scientific profile classes. Profile classes pursue the goal of…

Vertebrate species knowledge, a key factor for conserving biodiversity, is a compulsory part of school curricula. This study evaluated the vertebrate species knowledge of sixth-grade German grammar school pupils (aged 11-13) to investigate the influence of socio-demographic factors (gender, size of hometown, mother tongue), personal expectations…

Despite the fact that grade retention is now seen as controversial in many quarters, it remains common practice in numerous countries. Previous research on the effects of grade retention on student development has, however, generated ambiguous results, particularly in terms of motivational outcomes. This ambiguity has been attributed in part to a…

One important issue of the current empirical research on special education is the investigation of the effects of inclusive education compared to segregating education for students with learning disabilities (LD). For this purpose, measurement instruments have to be appropriate for students with LD and measurement equivalent across students with…

Positive socioemotional outcomes and developments represent important educational goals. Full-time ability grouping of gifted students has been criticized for potentially detrimental socioemotional effects. Therefore, in the present longitudinal study, we investigated whether or not social self-concepts and school-related attitudes and beliefs are…

This article focuses on vocabulary in the context of English-medium instruction at an international high school in Germany. Longitudinal testing was carried out using the Vocabulary Levels Test (VLT) (Nation, 1983; Schmitt, Schmitt, & Clapham, 2001), with 468 participants tested on entry to their first year of secondary school (Grade 6, aged…

The understanding of complex, dynamic and animate systems has a special standing in education for sustainable development and biology. Thus one important role of science teacher education is to promote student teachers' Content Related Knowledge (CRK) for teaching systems thinking, consisting of extensive Content Knowledge (CK) and well formed…

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…

Our study investigated whether problem-oriented designed ecology lessons with phases of direct instruction and of open experimentation foster the development of cross-domain and domain-specific components of "experimental problem-solving ability" better than conventional lessons in science. We used a paper-and-pencil test to assess…
