Plants have an enormous importance for life on earth but are often overlooked. This phenomenon called plant blindness is reinforced as students prefer to spend their recreation time with modern media rather than in nature. Mobile devices have become an omnipresent part of students' everyday lives. Nevertheless, direct experiences with plants are…

Since the turn of the century, an increasing number of low-stakes assessments (i.e., assessments without direct consequences for the test-takers) are being used to evaluate the quality of educational systems. Internationally, research has shown that low-stakes test results can be biased due to students' low test-taking motivation and that…

Expectancy-value theory (Eccles et al., 1983) is a prominent approach to explaining gender differences in math-related academic choices, with value beliefs acting as an important explanatory factor. Expectancy-value theory defines 4 value components: intrinsic value, attainment value, utility value, and cost. The present study followed up on…

The Test for Creative Thinking-Drawing Production (TCT-DP) is designed as an effective drawing-based instrument for measuring creative potential. Many studies report adaptation efforts in other cultures pointing out good psychometric properties of the instrument nonetheless revealing also some trouble spots. The present study includes adaptation…

The present study compared 124 adolescents from special schools for students with emotional and behavioural disturbances (EBDs) and 133 regular schooled adolescents with regard to their perceived maternal behaviour. It was also tested longitudinally whether effects of maternal parenting behaviour on subsequent externalising behaviour vary as a…

The aim of this study was to contribute to the understanding of the effectiveness of formative assessment interventions by analysing how the "quality of programme delivery" affects students' mathematics achievement and interest. Teachers (n = 17) implemented formative assessment in their ninth-grade mathematics classes and provided their…

Drawing on expectancy-value theory, the present study examined the unique contributions of the four major value beliefs and self-concept on achievement, self-reported effort, and teacher-rated behavioral engagement in mathematics. In particular, we examined the multiplicative effects of self-concept and task values on educational outcomes using…

One way to address the leaking pipeline toward STEM-related careers (i.e., science, technology, engineering, and mathematics) is to intervene on students' STEM motivation in school. However, a neglected question in intervention research is how such interventions affect motivation in subjects not targeted by the intervention. This question was…

This study evaluates a 12-item instrument for subjective measurement of mental load (ML) and mental effort (ME) by analysing different sources of validity evidence. The findings of an expert judgement (N = 8) provide "evidence based on test content" that the formulation of the items corresponds to the meaning of ML and ME. An empirical…

The purpose of the present study is to analyze German teacher trainers' views on high school German textbooks through the Rasch measurement model. A survey research design was employed and study group consisted of a total of 21 teacher trainers, three from each region and selected randomly from provinces which are located in seven regions and…

Prompting students to construct multiple solutions for modelling problems with vague conditions has been found to be an effective way to improve students' performance on interest-oriented measures. In the current study, we investigated the influence of this teaching element on students' performance. To assess the impact of prompting multiple…

Multiple matrix designs are commonly used in large-scale assessments to distribute test items to students. These designs comprise several booklets, each containing a subset of the complete item pool. Besides reducing the test burden of individual students, using various booklets allows aligning the difficulty of the presented items to the assumed…

By means of an international comparison, the research presented in the article aims to identify supporting and hindering school level factors for the use of ICT in secondary school mathematics lessons. The relationship between ICT use and the performance of Grade 9 students in mathematics is examined and further integrated into a multi-level model…

Students' individual learning is supposed to be based on cognitive and social processes. Therefore, students' social skills are assumed to play an important role for school performance. This study set out to investigate the links between students' peer relations skills and assertion skills and their grades for written performances and oral…

The concept of energy serves biologists as a powerful analytical model to describe phenomena that occurs in the natural world. Due to the concept's relevance, educational standards of different countries identify energy as a core idea for the teaching and learning of biology and other science subjects. However, previous research on students'…
