Enrichment programs provide learning opportunities for a broader or deeper examination of curricular or extracurricular topics and are popular in gifted education. Herein, we investigated the effectiveness of a statewide extracurricular enrichment program for gifted elementary school children in Germany. The program implemented a ”grass roots“ strategy by which local units developed and offered the enrichment courses, which spanned a broad array of topics. The courses targeted different outcomes, including students' cognitive abilities, school achievement, interests, creativity, self-control, self-concept, and social competencies. We compared third-grade students attending the enrichment program (N =423) with nonattending third-grade students (N = 2,328) by means of a propensity score analysis. Specifically, we controlled for potential selection effects and estimated the average causal effect of the enrichment program for children attending the program. The findings revealed positive program effects on academic achievement but not on the other targeted outcomes. 相似文献

The modern world can be described as a globalized risk society. It is characterized by increasing complexity, unpredictable consequences of techno-scientific innovations and production, and its environmental consequences. Therefore, chemistry, just like many other knowledge areas, is in an ongoing process of environmentalization. For example, green chemistry has emerged as a new chemical metadiscipline and movement. The philosophy of green chemistry was originally based on a suggestion of twelve principles for environment-friendly chemistry research and production. The present article problematizes limitations in green chemistry when it comes to education. It argues that the philosophy of green chemistry in the context of education needs to be extended with socio-critical perspectives to form educated professionals and citizens who are able to understand the complexity of the world, to make value-based decisions, and to become able to engage more thoroughly in democratic decision-making on sustainability issues. Different versions of sustainability-oriented science/chemistry education are discussed to sharpen a focus on the most complex type, which is Bildung-oriented, focusing emancipation and leading to eco-reflexive education. The term eco-reflexive is used for a problematizing stance towards the modern risk society, an understanding of the complexity of life and society and their interactions, and a responsibility for individual and collective actions towards socio-ecojustice and global sustainability. The philosophical foundation and characteristics of eco-reflexive science education are sketched on in the article. 相似文献

This paper describes a case study focusing on the subject matter knowledge, pedagogical content knowledge, and beliefs about science teaching of student teachers in Turkey at the start of their university education. The topic of interest was that of teaching chemical reactions in secondary chemistry education. A written test was developed which used the research literature on potential student misconceptions with regard to different aspects of chemical reactions. Thirty beginning science student teachers were tested, with an additional eight interviews from the student teachers in the same sample. The interviews focused on student teachers’ views about how to best teach chemical reactions in lower secondary chemistry classes. The results revealed deficits in the subject matter knowledge of the student teachers. It also became obvious that the teachers in this sample held very traditional and teacher-centred beliefs when it came to chemistry teaching at the secondary level. Their teaching attitudes were geared mainly towards the acquisition of facts by pupils, and often ignored the development of process-oriented skills. Implications for science teacher education are discussed. 相似文献

Peer assessment is an important component of a more participatory culture of learning. The articles collected in this special issue constitute a representative kaleidoscope of current research on peer assessment. In this commentary, we argue that research on peer assessment is currently in a stage of adolescence, grappling with the developmental tasks of identity formation and affiliation. Identity formation may be achieved by efforts towards a shared terminology and joint theory building, whereas affiliation may be reached by a more systematic consideration of research in related fields. To reach identity formation and affiliation, preliminary ideas for a cognitively toned, process-related model of peer assessment and links to related research fields, especially to research on collaborative learning, are presented. 相似文献

Summary Even though the EC-Treaty gives the impression of being unaware of multicultural societies, its regulations can still be interpreted
in such a way as to facilitate and even literally call for a European policy giving due consideration to the phase of adolescence
in multicultural societies.

Dadurch, dass Literaturnachweise und Publikationen zunehmend in elektronischer und auch vernetzter Form angeboten werden, haben Anzahl und Größe der von wissenschaftlichen Bibliotheken angebotenen Datenbanken erheblich zugenommen. In den verbreiteten Metasuchen über mehrere Datenbanken sind Suchen mit natürlichsprachlichen Suchbegriffen heute der kleinste gemeinsame Nenner. Sie führen aber wegen der bekannten Mängel des booleschen Retrievals häufig zu Treffermengen, die entweder zu speziell oder zu lang und zu unspezifisch sind. Die Technische Fakultät der Universität Bielefeld und die Universitätsbibliothek Bielefeld haben einen auf Fuzzy- Suchlogik basierenden Rechercheassistenten entwickelt, der die Suchanfragen der Benutzer in Teilsuchfragen an die externen Datenbanken zerlegt und die erhaltenen Teilsuchergebnisse in einer nach Relevanz sortierten Liste kumuliert. Es ist möglich, Suchbegriffe zu gewichten und durch Fuzzy- Aggregationsoperatoren zu verknüpfen, die auf der Benutzeroberfläche durch natürlichsprachliche Fuzzy-Quantoren wie möglichst viele, einige u.a. repräsentiert werden. Die Suchparameter werden in der intuitiv bedienbaren einfachen Suche automatisch nach heuristischen Regeln ermittelt, können in einer erweiterten Suche aber auch explizit eingestellt werden. Die Suchmöglichkeiten werden durch Suchen nach ähnlichen Dokumenten und Vorschlagslisten für weitere Suchbegriffe ergänzt. Wir beschreiben die Ausgangssituation, den theoretischen Ansatz, die Benutzeroberfläche und berichten über eine Evalution zur Benutzung und einen Vergleichstest betreffend die Effizienz der Retrievalmethodik. 相似文献
