Elternvertreter mit Migrationshintergrund an allgemeinbildenden Schulen

Parents with a migration background are underrepresented among parent representatives at schools in Germany. However, increased involvement of these parents is essential for a lively democratic culture. To explore the motivations of parents with migration background regarding their school involvement, interviews with N?=?31 parent representatives with migration background were content analysed, starting deductively from a set of categories according to the theory of planned behaviour. In the analysis, the main category ??attitude?? was deductively subdivided into ??motivation in the course of action/intrinsic value??, ??results and consequences regarding own interests?? and ??results and consequences regarding others/altruistic motivation??. ??Subjective norm?? was inductively differentiated into ??other parents??, ??teachers and leadership team?? and ??other persons/perceived general expectations??; ??perceived behavioural control?? was differentiated into the subcategories ??assertiveness and freedom from anxiety??, ??language competence??, ??socioeconomic background??, ??availability of time??, ??setting in school and school district?? and ??field expertise and know-how??. Additionally, ??habit?? was deductively established and retained as a main category. Analysis of 513 statements resulted in an interrater-agreement of ???=?0.82. Implications for working with parents in an intercultural context are discussed.     

Disparitäten der Bildungsbeteiligung und des Kompetenzerwerbs

Zusammenfassung Herkunftsbedingte Unterschiede der Bildungsbeteiligung und des Kompetenzerwerbs stellen einen Untersuchungsschwerpunkt in der Pisa-Studie dar. In der Bundesrepublik war ein besonders enger Zusammenhang zwischen Strukturmerkmalen famili?rer Lebensverh?ltnisse (sozio?konomischer Status, Bildungsniveau, Migrationstatus), Bildungsbeteiligung und Kompetenzerwerb nachweisbar. Ziel des Beitrags ist es, auf Grundlage der Daten der nationalen Erweiterung von PISA die disparit?tserzeugenden Effekte famili?rer Strukturmerkmale durch Prozessmerkmale famili?rer Lebensverh?ltnisse (kulturelle und kommunikative Praxis), institutionelle (Schulform) und psychologische Faktoren zu erkl?ren. Dies geschieht in zwei Schritten: Zun?chst wird mit Hilfe von Strukturgleichungsmodellen gezeigt, dass die Effekte von famili?ren Strukturmerkmalen überwiegend durch die kulturelle Praxis von Familien vermittelt sind. In einer sequentiellen Berechnung von Regressionsmodellen ergeben sich sodann deutliche Hinweise darauf, dass die Wirkung famili?rer Struktur- und Prozessmerkmale im Wesentlichen über individuelle F?higkeits- und Motivationsunterschiede (kognitive Grundf?higkeiten, Lesegeschwindigkeit, Leseinteresse, metakognitive Lernstrategien) transportiert werden. Die psychologischen und institutionellen Vermittlungsmechanismen tragen gemeinsam, aber auch jeweils spezifisch und damit kumulativ zu sozialen Unterschieden im Kompetenzerwerb bei.

Summary Disparities in Educational Participation and Attainment: An Institutional and Individual Mediation Model The effect of students’ social background on their educational participation and attainment is a central focus of the PISA study. For Germany, the link between structural features of the family background (socio-economic status, level of education, migration status) and educational participation and attainment was shown to be particularly strong. Drawing on data from the German national extension of the PISA study, an explanation of these disparity effects is proposed, relying on process-based features (cultural and communicative practices), institutional factors (school type) and psychological factors. This is done in a two-step approach. First, structural equation models are used to show that most effects of family background structures are mediated by families’ cultural practices. Second, sequential analyses of regression models are run, providing strong evidence to suggest that the effects of family structures and processes are essentially transmitted through individual differences in competencies and motivation (basic cognitive abilities, reading speed, interest in reading, meta-cognitive learning strategies). Psychological and institutional mediation mechanisms contribute, jointly as well as individually, and thus cumulatively, to social differences in attainment.

New Approaches to Spoken Document Retrieval

This paper presents four novel techniques for open-vocabulary spoken document retrieval: a method to detect slots that possibly contain a query feature; a method to estimate occurrence probabilities; a technique that we call collection-wide probability re-estimation and a weighting scheme which takes advantage of the fact that long query features are detected more reliably. These four techniques have been evaluated using the TREC-6 spoken document retrieval test collection to determine the improvements in retrieval effectiveness with respect to a baseline retrieval method. Results show that the retrieval effectiveness can be improved considerably despite the large number of speech recognition errors.
