Plant-based dietary choices can help to mitigate climate change. Yet, most people still consume meat. Social identity influences dietary choices. This study tests whether shared identity, pro-veg*n norms, attitudes, and dietary intentions, can be strengthened via a vegan cooking workshop for children. Pupils (N = 155) cooked in small groups (3-6…

The professional development of academic teaching staff has become increasingly visible in higher education, even though there is still not enough evidence on how teachers change through such initiatives. Because flexibility in teaching is a commonly found demand, knowledge and core beliefs of one's own ability to teach are pivotal. We present…

Migrant students tend to underperform in Science, Technology, Engineering, and Mathematics (STEM) subjects and are less likely to pursue higher education in STEM when compared with their nonmigrant peers. Given the substantial increase in migration, this disparity has been a central concern in science education in many European countries. The…

We report on research conducted during a language assessment literacy (LAL) project set up for employees at a university language centre. Teachers, students and an external accreditation body requested a revision of the end-of-course exams to increase comparability, transparency and alignment to course aims. We used a collaborative approach where…

Introduction: The global trend of new curricula in many OECD countries indicates that social interaction skills are becoming increasingly important. Educators need to start fostering the development of learners' social competences, which requires development of their own knowledge and skills. This study investigated the possible change in…

Many studies have shown a decrease in scientific interest with an increase in age. Since interest is linked to a high degree of deep-level learning, it is of great relevance to foster interest in science. This study investigates interest in biology from 7th, 9th, and 12th grade students in Germany (N=257). Results show a significantly lower…

The Internet has become a pivotal source of information among university students. However, studies routinely show that many students lack digital information literacy skills (i.e. skills needed to find and evaluate information online). In this paper, we report results from an experimental study testing the effect of a workshop for third-year…

Bullying against lesbian and gay adolescents continues to be a problem in Western societies. Interventions to reduce homonegative attitudes could help to address bullying. We evaluated the effectiveness of a workshop against homonegativity in adolescents (N = 214) aged between 14 and 16 years in a pretest, posttest, follow-up design with a control…

Diagnosing student achievement in a formative way is a crucial skill for planning and carrying out effective mathematics lessons. This study takes a subject-specific view and aims at investigating diagnostic competence in the field of mathematical functions at secondary level and how to improve it. Following three evidence-based design principles,…

For developing professional development (PD) programs, research suggests referring to effective components. In developing a PD program on classroom dialogue, we explored to what extent effective components could be addressed. We conducted a study with two groups. In the "Dialogic Video Cycle" (DVC), six German teachers participated in a…

This pilot study evaluated the preliminary short- and middle-term impact of a nation-wide, school-based prevention initiative on antisocial behaviour of preschool and primary school pupils in Luxembourg. Seventeen preschool and reception classes (n = 183) were assigned to intervention and comparison conditions. The intervention included…
