This study focuses on students who change from the academic to the non-academic school track after grade 7 (probationary year) in Berlin. We examined which individual student characteristics (e.?g., performance, school biography, family background) predict school change after the probationary year. We were particularly interested as to whether there are secondary effects of social background, after controlling for differences in performance. Our analyses were based on data from a study which included a whole cohort of school track changers (N?=?754) who were compared with students that remained at the academic track (N?=?1470). In order to predict the change of school type, multivariate logistic regression analyses were performed. Results revealed significant differences between both groups regarding all observed characteristics. Performance-related characteristics were the best predictors of track change. After controlling for these characteristics, no further significant effects for other predictors were observable (i.?e., no secondary effects of social background were present). 相似文献

Research in clinical samples suggests that the relationship between intelligence and academic achievement might be moderated by sustained attention. The present study aimed to explore whether this interaction could be observed in a non-clinical sample. We investigated a sample of 11th and 12th grade students (N = 231). An overall performance score and a quality of performance score in sustained attention as well as verbal, numerical, and general intelligence scores served as predictors. Achievement criteria were grades in math and German as well as Grade Point Average (GPA) obtained after testing. Both types of sustained attention scores were significantly related to school performance, but only the quality of performance score incrementally contributed to the prediction of school performance above and beyond intelligence. Overall differences in the sustained attention test significantly moderated the relationship between verbal intelligence and German grades. Quality of performance moderated the relationship between general intelligence and GPA as well as the one between numerical intelligence and math grades. The study elucidates the interplay between sustained attention, intelligence, and school performance in a non-clinical sample. 相似文献

The self-regulation of motivation represents a key feature of self-regulated learning. Recent studies have documented that students use a variety of strategies to sustain their learning motivation and that most of these strategies have positive effects. However, less is known about how students integrate the various motivational strategies into an individual motivational regulation profile and which kind of profiles are most adaptive with respect to enhanced effort and persistence. To shed more light on this issue, we examined the motivational regulation profiles within two samples of German high-school and college students. In Study 1 (N = 231 11th and 12th grade students), latent profile analysis revealed five subgroups of students holding different motivational regulation profiles. In Study 2 (N = 600 college students), the five class solution was replicated with slight changes in the nature of the profiles. In both studies, profiles with a higher overall level of motivational strategy use were associated with a higher level of effort and achievement. Regarding differences in profile shape, results indicated that profiles emphasizing mastery and/or performance-approach self-talk were most adaptive. Implications of the findings for future research on motivational regulation are discussed. 相似文献

The present study examined to which extent different motivational concepts contribute to the prediction of school achievement among adolescent students independently from intelligence. A sample of 342 11th and 12th graders (age M = 16.94; SD = .71) was investigated. Students gave self-reports on domain-specific values, ability self-perceptions, goals, and achievement motives. Hierarchical regression and relative weights analyses were performed with grades in math and German as dependent variables and intelligence as well as motivational measures as independent variables. Beyond intelligence, different motivational constructs incrementally contributed to the prediction of school achievement. Domain-specific ability self-perceptions and values showed the highest increments whereas achievement motives and goal orientations explained less additional variance. Even when prior achievement was controlled, some motivational concepts still proved to contribute to the prediction of subsequent performance. In the light of these findings, we discuss the importance of motivation in educational contexts. 相似文献

Building on the notion that motivation energizes and directs resources in achievement situations, we argue that goal orientations affect perceptions of own intelligence and that the effect of goals on performance is partly mediated by self-estimates of intelligence. Studies 1 (n = 89) and 2 (n = 165) investigated the association of goal orientations and self-estimated intelligence in university-student samples. Study 3 (n = 164) tested an integrated model of goal orientations and self-estimated intelligence to predict school performance. Goal orientations explained 7 to 11% of the variance in self-estimated intelligence (controlling for gender, age, and psychometric intelligence). Persons with high performance-approach goals consistently overestimated and persons holding high performance-avoidance goals underestimated their intelligence. Performance goals affected academic performance indirectly via self-estimated intelligence, whereas learning goals were directly related to performance. Findings are discussed regarding their importance for the understanding of the function of motivation and ability self-perceptions for performance. 相似文献

Zusammenfassung. Ziele des MeDoc-Projektes waren die Konzeption, prototypische Entwicklung und Erprobung volltextbasierter Informations- und
Publikationsdienste für die Informatik, um den Informationsaustausch und die Literaturversorgung in der Wissenschaft effektiver
gestalten zu k?nnen. Dazu wurde im Rahmen des Projektes ein internet-basiertes System entwickelt, in dem Informatik & Fachinformation
im Volltext gespeichert, recherchiert, abgerufen und gelesen werden kann und das die Suche nach Informatik-Literatur in heterogenen,
verteilten Informationsquellen im Internet unterstützt. Das Informationsangebot ist dabei teilweise kostenpflichtig. In diesem
Artikel werden Ziele, Funktionalit?t und Architektur des MeDoc-Systems beschrieben.
