The relation between prior knowledge and learning has been investigated in many studies. However, a recent meta-analysis showed that most of these studies suffered from serious methodological shortcomings, as they failed to account for knowledge growth over time, possible ceiling effects for learners with high prior knowledge, moderating effects…

Critical thinking is internationally recognized as an important aspect of school education. Particularly in the United States, Scandinavian, and Asian countries, critical thinking is firmly anchored in school curricula. In this context, critical thinking is often aligned with critical thinking skills, which can be taught in structured programs and…

Ability grouping provides an advanced learning environment for gifted students, possibly buffering them from common long-term increases in academic boredom. We present a 3.5-year longitudinal investigation, spanning four waves of measurement, featuring secondary school students (Grades 5 through 8) from five different German schools with full-time…

This article defines the term twice-exceptional as being gifted (highly able) and having challenges with learning or physical disabilities. The focus is on understanding these children, who are brilliant in one way but at the same time in some situations are at risk. The biggest challenges they face are misunderstanding and misdiagnosis. This…

Gifted education needs to be constantly improved and differentiated for various types of domain-specific giftedness, especially in STEM (science, technology, engineering, and mathematics) subjects. Therefore, teachers must be adequately trained in the field of giftedness. The aim of this study was to investigate (the Big Five) personality factors…

Some research has investigated the big five personality dimensions among gifted individuals, but these individual studies have provided inconclusive results. The current meta-analysis examined the nature of the relationship between the big five dimensions and giftedness among individuals. Hedge's unbiased g was used as the effect size metric, and…

Implementing programs for gifted students requires solutions on multiple levels of the education system. In this article, Heinz Neber suggests streamlining the topic with five interacting, systemic levels. Each level requires its own definitions and clarifications. These should be coordinated and prioritized according to prominent goals and…

Gifted underachievers perform worse in school than would be expected based on their high intelligence. Possible causes for underachievement are low motivational dispositions (need for cognition) and metacognitive competences. This study tested the interplay of these variables longitudinally with gifted and non-gifted students from Germany…

Stereotypical assumptions associating high levels of giftedness and outstanding performance with maladaptive behavioral characteristics and personality traits (cf. disharmony stereotype) are rather prevalent in the school context as well as in the musical domain. Such preconceptions among teachers can influence student assessment and corresponding…

Approaches for inclusive science teaching currently tend to focus on only one dimension of diversity at a time. This neglects the fact that diversity is multidimensional in nature, and the consideration of only one dimension of diversity can yield inclusive practices with limited scope. Therefore, the goal of the project "Diversity in Science…

Given that exclusive boarding schools in Germany are repeatedly referred to in public and academic discourses as places of elite education, the question arises as to the consequences of boarding school socialisation and how these schools affect the post-school biographies of their alumni. This qualitative study examines the autobiographies of…

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…

Negative stereotypes about intellectually gifted individuals prevail among teachers and in society although empirical research has debunked them. They are also dominant in mass media representations of gifted individuals such as newspaper reports. The present study investigated whether stereotypic representations in newspaper articles contribute…

Historical and autobiographical approaches are combined with interviews to analyze the case of the Europa-Kontakt in pre-1989 Poland and West Germany within the framework of Europeanization. The international education encounters exemplify the tendencies to Europeanize, which emerged in both countries despite the Iron Curtain. The painful…

Effects of full-time ability grouping on students' academic self-concept (ASC) and mathematics achievement were investigated in the first 3 years of secondary school (four waves of measurement; students' average age at first wave: 10.5 years). Students were primarily from middle and upper class families living in southern Germany. The study sample…
