  abstract  = {It is well-documented that academic achievement is associated with students' self-perceptions of their academic abilities, that is, their academic self-concepts. However, low-achieving students may apply self-protective strategies to maintain a favorable academic self-concept when evaluating their academic abilities. Consequently, the relation between achievement and academic self-concept might not be linear across the entire achievement continuum. Capitalizing on representative data from three large-scale assessments (i.e., TIMSS, PIRLS, PISA; N = 470,804), we conducted an integrative data analysis to address nonlinear trends in the relations between achievement and the corresponding self-concepts in mathematics and the verbal domain across 13 countries and 2 age groups (i.e., elementary and secondary school students). Polynomial and interrupted regression analyses showed nonlinear relations in secondary school students, demonstrating that the relations between achievement and the corresponding self-concepts were weaker for lower achieving students than for higher achieving students. Nonlinear effects were also present in younger students, but the pattern of results was rather heterogeneous. We discuss implications for theory as well as for the assessment and interpretation of self-concept.},

  abstract  = {Cognitive representations and beliefs are what comprise an individual's self-concept. A positive self-concept is related to and influences academic achievement, and the relationship between a domain-specific self-concept and achievement in the same domain is positive and strong. However, insufficient attention has been paid to these issues among multilingual children. More importantly, since instruction strongly contributes to the development of metacognition and executive functions (EFs), and since the bilingual advantage hypothesis holds that the constant management of multiple languages entails benefits for EF, we bring together these important issues in the present study. We examine the relationship between domain-specific self-concepts and standardized assessment of reading and spelling competences against the background of potential differences in self-concept between monolingual and multilingual German children. While between-group comparisons revealed no significant differences for self-concept nor reading competency, monolinguals outperformed multilinguals in spelling. Correlations between domain-specific self-concepts and academic achievement in reading comprehension, reading fluency, and spelling were positive and significant for both groups. Regardless of language background, children's evaluations of their academic achievement (reading and spelling) were realistic. We argue, on a theoretical basis, that metacognition and EFs could facilitate a bilingual advantage and improve educational outcomes.},

  abstract  = {The study aims to investigate the contribution of individual characteristics and gender stereotypes of secondary school pupils in academic achievement in math and foreign language. A sample of pupils reported in 6th and 7th grades (three waves) their self-perceived ability and motivation for math and foreign language learning, math and foreign language gender stereotypes, implicit theories of intelligence; academic achievement (grades) in math in foreign language is also included in the analysis. Regression analysis and Mann Whitney U Test demonstrated that self-perceived ability in math and incremental theory of intelligence are significant predictors for academic achievement in maths. Boys are characterised by higher level of self-perceived abilities and motivation for learning math. However, academic achievement of girls in maths and foreign languages are higher as compared to boys. Pupils learning two foreign languages demonstrate higher level of self-perceived abilities for motivation and learning math and less expressed gender stereotypes about success in learning math and foreign languages. Study findings can be used for designing educational programmes for mathematics and foreign languages, professional development and finding solutions for individualized approach in school education.},

We examine whether measures of ethnic diversity are related to achievement (mathematics, reading) and feeling of belonging with one's peers over and above commonly investigated composition characteristics. Multilevel analyses were based on data from a representative sample of 18,762 elementary school students in 903 classrooms. The proportion of minority students and diversity measures showed negative associations with student outcomes in separate models. Including diversity measures and the proportion of minority students, diversity of minority students mostly lost its significance. However, the results suggest that diversity measures may provide additional information over and above other classroom characteristics for some student outcomes. The various measures of diversity led to comparable results. (PsycINFO Database Record (c) 2017 APA, all rights reserved)},

Based on latent change models, the results indicated associations between parental separation and short-term declines in academic achievement as well as short-term and longer term declines in self-esteem. Although optimism in general showed positive associations with academic achievement and self-esteem, its role as a protective factor proved to be particularly important for academic achievement in adjustment following parental separation.},

  abstract  = {This paper reviews empirical evidence on the effect of the composition of a student body on academic achievement of students. After defining the term composition effect, methodological aspects regarding the study of composition effects are considered. International and national evidence for the composition of a student body with respect to students' abilities, social, and ethnic background is then presented. Whereas international studies find evidence for social, ethnic, and achievement composition variables, national studies reveal that mean achievement level of a school or class is the most important composition variable in Germany. However, this effect is confounded with school track and social composition, which itself exerts a small incremental effect. Ethnic composition, however, does not seem to play an important role. The paper closes with a presentation of the underlying processes of composition effects and a discussion on how the composition of a student body is considered in school governance practices.},
