Lower reading and mathematics performance of Turkish immigrant students as compared to mainstream European students could reflect differential learning outcomes, differential socioeconomic backgrounds of the groups, differential mainstream language proficiency, and/or test bias. Using PISA reading and mathematics scores of these groups, we examined the role of bias and various measures related to immigrant integration policies of the host societies. Results of a multilevel analysis of reading and mathematics tests demonstrated that at individual level, students with higher scores on an index of economic, social, and cultural status obtained higher achievement scores. At country level, MIPEX scores of education and the human development index of participating countries could predict differences in reading results but not in mathematics. After correction for background characteristics, effect sizes showed a difference of .65 SD (down from a value of .96 before correction) for reading and .58 SD (down from .78) for mathematics. However, a similar correction for background variables increased the score differences between Turkish immigrants and mainstreamers.  相似文献

This study shows the results of a two-year longitudinal study where the same participants were followed for two consecutive years as they enter secondary school (aged 12–14 years). The main issue was to investigate the development of both the quantity and the quality of metacognitive skills. Another issue was to establish whether the development of metacognitive skillfulness is intelligence-related or relatively intelligence-independent. Finally, the generality vs. domain-specificity of developing metacognitive skillfulness was investigated. Thirty-two secondary school students participated in this study. While thinking aloud they performed two different tasks representing two different domains: A text-studying task for history and a problem-solving task for math. Participants' intellectual ability, metacognitive skillfulness and learning performance were assessed. Results show a quantitative as well as a qualitative growth in metacognitive skillfulness. Furthermore, results of both years show that metacognitive skillfulness contributed to learning performance (partly) independent of intellectual ability. A parallel development of metacognitive and intellectual ability was found. Finally, metacognitive skills predominantly appear to be general. Domain-specific metacognitive skills, however, played a substantial, but minor role as well in both years. Instructional implications are being discussed.  相似文献

75 infants (mean age 15 months) were observed 3 times in the Strange Situation with their professional caregivers, mothers, and fathers. Sensitivity of these attachment figures to the infant's signals during free play, as well as a number of day-care characteristics, were assessed. Attachment classification distribution of infant-caregiver dyads did not differ significantly from infant-mother or infant-father attachment classification distributions. The quality of infant-caregiver attachment was independent of both infant-mother and infant-father attachments. About 10% of the infants had 3 insecure attachments. Professional caregivers observed with more than 1 infant did not have similar types of attachment classifications to all infants with whom they were observed. Infants who were securely attached to their professional caregivers spent more hours per week in day-care, and came from a middle-class background. Their caregivers appeared to be younger and more sensitive during free play than caregivers with whom the infants developed an insecure relationship.  相似文献

The book begins with a discussion of the debates on history education as they developed in Great Britain during the last decades of the previous century. In these debates, reference is often made to the views of the philosopher and historian R. G. Collingwood. However, according to the author, his philosophy of history is usually misunderstood. Besides correcting the various misinterpretations of Collingwood's views on history, special attention is paid to his theory of (historical) imagination. In the final part of the book, the relevance of Collingwood's philosophy for more general educational issues is discussed and compared with the views of Hirst, Bloom and Bruner.  相似文献

Zusammenfassung. Um einen auf UML basierenden Entwicklungsprozess bewerten und verbessern zu können, werden Metriken für UML-Modelle definiert. Wir stellen einen Satz derartiger Metriken vor und diskutieren ihre Tauglichkeit. Unsere Metriken sind generisch definiert, sie werden zur Bewertung der einzelnen UML-Diagramme spezialisiert. Wir berichten vom Einsatz der Metriken zur Evaluation eines Prozessmodells, das in der Lehrveranstaltung Software-Praktikum eingesetzt wird. Eingegangen am 2. Januar 2001/Angenommen am 20. Dezember 2002CR Subject Classification: D.2.2, D.2.8, D.2.9, K.3.2, K.6.3  相似文献

In this case study, the professional mathematics teacher identity (PMTI) of final year mathematics education students is investigated in terms of their self-perceived and actualised identity. These prospective teachers were required to discuss and describe their own PMTI in terms of three aspects: mathematics specialisation, teaching-and-learning specialisation, and caring. Subsequently, they were observed in the classroom, where the actualisation of their PMTI was considered in terms of the same three. The participants’ perceptions of their own PMTI and the actualisation of that PMTI in the classroom were found not to be congruent. While their self-perceptions regarding their prowess as Mathematics Specialists were accurate, since this is concretely tested as part of their studies, their self-perceptions as teaching-and-learning specialists and particularly as Carers, were not verifiable in their classroom practice. Espoused theory, theory that the individual perceives as true and valid, and which may thus be seen as intrinsic to their PMTI’s, is not necessarily enacted.  相似文献

This article explores the effect of computerized scaffolding with different scaffolds (structuring vs. problematizing) on intra-group metacognitive interaction. In this study, we investigate 4 types of intra-group social metacognitive activities; namely ignored, accepted, shared and co-constructed metacognitive activities in 18 triads (6 control groups; no scaffolds and 12 experimental groups; 6 structuring scaffolds and 6 problematizing scaffolds). We found that groups receiving scaffolding showed significantly more intra-group interactions in which the group members co-construct social metacognitive activities. Groups receiving problematizing scaffolds showed significantly less ignored and more co-constructed social metacognitive interaction compared to groups receiving structuring scaffolds. These findings indicate that scaffolding positively influenced the group members’ intra-group social metacognitive interaction. We also found a significant relation between students’ participation in intra-group social metacognitive interaction and students’ metacognitive knowledge. Twelve percent of the variance in students’ metacognitive knowledge was explained by their participation in intra-group shared social metacognitive interaction. Therefore, future research should consider how to design scaffolds that elicit intra-group social metacognitive interaction among group members to enhance the development of students’ metacognitive knowledge.  相似文献

In this essay Luc Van den Berge and Stefan Ramaekers take the idea(l) of “scientific parenting” as an example of ambiguities that are typical of our late‐modern condition. On the one hand, parenting seems like a natural thing to do, which makes “scientific parenting” sound like an oxymoron; on the other hand, a disengaged stance informed by the latest scientific findings is uncritically demanded of parents, as such an approach is conceived of as a panacea. Instead of taking sides in this discussion, the authors seek a way to make sense of it, drawing upon the work of Charles Taylor, who offers a striking account of our contingent modern condition as well as of our ontological human constitution. They focus particularly on two examples Taylor gives where the contingent self‐understanding does not coincide with our timeless human features. This opens a space for what might be considered paradoxes in our late‐modern Western culture. This essay thus confronts Taylor's philosophy with the new parenting discourse to reveal how our moral horizons have evolved. Following this approach, the authors both expand on Taylor's thinking about our late modernity and at the same time try to assess the new scientific parenting discourse.  相似文献

This meta‐analysis assessed the effect of community service on adolescent development and the moderation of this effect by reflection, community service, and adolescent characteristics to explicate the mechanisms underlying community service effects. Random effects analyses, based on 49 studies (24,477 participants, 12–20 years old), revealed that community service had positive effects on academic, personal, social, and civic outcomes. Moderation analyses indicated that reflection was essential; the effect for studies that include reflection was substantial (mean ES = .41) while community service in the absence of reflection yielded negligible benefits (mean ES = .05). Effects increased when studies include more frequent reflection and community service, reflection on academic content, and older adolescents. These findings have implications for understanding and improving community service.  相似文献
