This longitudinal study investigated the cross-lagged associations between children’s academic skill development, task-avoidant behaviour in the context of homework, and parental beliefs about their child’s success from kindergarten to Grade 2. The participants were 1267 children. The children’s pre-skills were assessed at the end of the kindergarten year, and math and reading skills at the end of Grade 1 and Grade 2. Parents provided ratings of their beliefs about their children’s school success and task-avoidant behaviour with regard to homework at the end of Grades 1 and 2. The results showed that children’s math and reading skills predicted children’s task-avoidant behaviour regarding homework as rated by mothers, but not by fathers, when autoregressive effects were taken into account. In addition, task-avoidant behaviour predicted the mothers’ subsequent beliefs about their children’s school success but not vice versa. A reciprocal effect was found between fathers’ beliefs about success and children’s task-avoidance. 相似文献

Social factors play an important role in determining whether instructional communication in computer-supported settings will be successful. Social presence is a social factor, specifically addressing the feeling of being present with another person in a virtual environment. This article describes possibilities to influence the feeling of social presence in synchronous learning scenarios using desktop collaborative virtual environments (CVEs). Desktop CVEs are technically simple compared with immersive CVEs and can be adapted according to the needs of the users. In this article, possible adaptations are described using the example of the desktop CVE virtual team room. In CVEs, users are represented as avatars. Avatars may or may not convey nonverbal signals. The focus of the article is on whether the actual use of nonverbal signals can affect the sense of social presence and thus help to establish and maintain the learner's motivation and provide support for structuring social interaction in learning situations. The paper provides a review of exploratory studies and experiments as well as a report on the author's own studies. Future research questions concerning learning in CVEs are discussed. 相似文献

This study investigated teachers’ professional identity development. Using Dialogical Self Theory and a socio-cultural semiotic mediational perspective, we focused on pre- and in-service teachers’ communication of professional role expectations and related feelings when solving pedagogical dilemmas to reveal aspects of their professional identity construction. Data were collected from 102 pre- and 90 in-service teachers by asking them to solve seven pedagogical dilemmas. We report: (1) how pre- and in-service teachers solved pedagogical dilemmas in terms of communicating professional role expectations and related feelings; (2) how pre- and in-service teachers differed in the feelings they reported and the solutions they gave when solving pedagogical dilemmas; and (3) how the communication of professional role expectations and feelings was related to pre- and in-service teachers’ work experience. Finally, we discuss the implications of our study for initial and continuing teacher education programmes. 相似文献

Zusammenfassung Der Frage nach den Steigerungsm?glichkeiten der (informellen) „Grundbildung“ und der F?rderung von Basiskompetenzen wird aus bildungsbiographischer Perspektive nachgegangen, indem die familiale Bildungswirklichkeit in ihrem Wechselverh?ltnis zur schulischen Bildungswirklichkeit anhand eines Fallbeispiels dargestellt wird. Am Beispiel der Vermittlung und Aneignung von information literacy wird gezeigt, dass es unumg?nglich ist, in der schulischen Bildungswirklichkeit von einer Kulturrelativit?t und Kulturgebundenheit von information literacy als wichtigem Element von informeller Bildung auszugehen, die an unterschiedlichen Bildungsorten erworben wird und eine entsprechende Vernetzung der Bildungsorte voraussetzt. Um Bildungsarmut zu verhindern und m?glichst für alle Menschen die Voraussetzungen für die Gestaltung eines eigenen Lebenslaufs und die Entwicklung einer verst?ndigen kulturellen Teilhabe- und sozialen Anschlussf?higkeit zu schaffen, muss sich, so die These, die Institution Schule mehr für informelle Bildung und die p?dagogische Bearbeitung von kultureller Differenz sowie den Umgang mit Heterogenit?t ?ffnen, damit der oft diskriminierende Umgang mit kultureller und sozialer Differenz in der Schule nicht in eine fürsorgliche (p?dagogische) Belagerung und Entmündigung der Schüler durch die Schule umschl?gt. Dabei ist es wichtig, die informellen Bildungsleistungen der Familie anzuerkennen und weiter zu entwickeln und in Verbindung mit der verst?rkten F?rderung von Erziehungspartnerschaften zwischen Eltern und p?dagogischen Fachkr?ften darauf hinzuarbeiten, die Grundbildung und den Erwerb von notwendigen Basiskompetenzen zu st?rken und das schulische Abwertungsdilemma von au?erschulisch erworbenen informellen Bildungsgehalten „f?rderdidaktisch“ zu bearbeiten. 相似文献

Recent highly publicized cases of scientific misconduct have raised concerns about its consequences for academic careers. Previous and anecdotal evidence suggests that these reach far beyond the fraudulent scientist and (his or) her career, affecting coauthors and institutions. Here we show that the negative effects of scientific misconduct spill over to uninvolved prior collaborators: compared to a control group, prior collaborators of misconducting scientists, who have no connection to the misconduct case, are cited 8–9% less often afterwards. We suggest that the mechanism underlying this phenomenon is stigmatization by mere association. The result suggests that scientific misconduct generates large indirect costs in the form of mistrust towards a wider range of research findings than was previously assumed. The far-reaching fallout of misconduct implies that potential whistleblowers might be disinclined to make their concerns public in order to protect their own reputation and career. 相似文献

Polyethylene-nanocomposites with CaCO3-weight fractions from 0 to 15 wt.% were prepared by in-situ polymeriza- tion with Me2Si(Ind)2ZrCl2/MAO metallocene catalysts. A high activity especially in the presence of TIBA was observed. The morphology was investigated by using raster electron microscopy (REM) showing that the CaCO3-nanoparticles are uniformly distributed. The melting temperatures and the crystallization temperatures are not much influenced by increasing filler content. 相似文献

This study investigated the influence of first language (L1) phonology on second language (L2) early reading skills in Sylheti-English bilinguals (N = 58; 48% girls; British Bangladeshi) and their monolingual-English peers (N = 43; 45% girls; 96% White British, 4% multiethnic British) in a diaspora context. Language-specific phonological awareness and nonword repetition were tested at two time points (6;2–7;8 years-old). At Time 1, the bilinguals had lower productive accuracy for phonological sequences that violated their L1 phonology (d = .56; .84), and these skills accounted for a significant amount of variance in their reading accuracy. At Time 2, the language-specific effects were no longer present. These findings highlight the importance of considering language structure in multilingual early literacy development. 相似文献
