From a contact theory perspective, links between variation in young adults' perceptions of communication with their grandparents and attitudes towards older adults are examined. The analysis pays particular attention to variation in communication with multiple grandparents, and finds links between that and perceived variability in the older adult population as a whole. More variation in perceptions of communication with grandparents is associated with perceptions of older adults as more heterogeneous. However, variation in grandparent relationships is associated with more negative attitudes towards older adults on measures of attitudinal central tendency. The results are discussed in terms of intergroup communication processes, contact theory and possible interventions to reduce prejudice in this and other contexts. 相似文献
As we enter the 21st century it seems likely that the collection of methodologies and methods that have constituted PAR will continue to permeate mainstream research. There is increasing evidence, for example, that the discourse of participatory action research is now being widely used by international development agencies, NGOs and related organisations to promote a wide array of educational, healthcare and social programmes. This paper argues that the increasing popularity and use of PAR over recent years poses both possibilities and problems for researchers. In particular, it will discuss the challenges that this process presents to the concept of participation within PAR, as well as the implications it has for constructing methodologies for inclusive forms of participatory research. 相似文献
Zusammenfassung Der vorliegende Beitrag besch?ftigt sich aus der Perspektive von Theorien zum Kompetenzerwerb mit dem Zusammenhang zwischen
dem fachspezifischen Professionswissen von Mathematiklehrkr?ften und ihrer Ausbildung und beruflichen Fortbildung. Dabei wurden
institutionelle Unterschiede der Lehramtsausbildung wie auch individuelle Unterschiede im Studienerfolg, der Berufserfahrung
und der besuchten beruflichen Fortbildungen untersucht. Die Analysen basieren auf Daten von 195 Mathematiklehrkr?ften, die
an der COACTIV-Studie teilnahmen. Unsere Ergebnisse zeigen, dass sich Lehrkr?fte unterschiedlicher Lehr?mter deutlich in ihrem
professionellen Wissen unterscheiden und dass insbesondere der Erfolg im Studium mit besseren Leistungen im Fachwissen und
im fachdidaktischen Wissen zusammen hing. Wir diskutieren Implikationen unserer Ergebnisse vor dem Hintergrund der Lehramtsausbildung
und beruflicher Fortbildungen.

Attitudes to science develop early in life. In early childhood, the almost exclusively female staff members lack confidence
in the area of science, and are therefore unable to develop an adequate science program for their children. In an action research
project involving one third of the adults staffing a playcentre, during one term, the science programme in the centre was
considerably improved, on measures of dialogues with the children, and of planning activities specifically for science. The
staff members, mothers in the playcentre, reported increased confidence in talking with children about science topics, and
a significant change in their interaction patterns both with their own families and with other children in the playcentre
science programme. The action research method was found to be particularly helpful in supporting the group of parents in improving
their centre's science program.
Specializations: mathematics and science curricula and teacher education in early childhood. 相似文献
Retarded conditioned response (CR) acquisition produced by unconditioned stimulus (US) preexposures has been attributed either to interference resulting from contextual conditioning or to habituation of the US. Both perspectives assume that the amount of retardation is directly related to the number of US preexposures. This assumption was examined in two experiments. In Experiment 1, separate groups of rabbits received 200 paraorbital shock US preexposures either in one session or spread equally over 10 daily sessions. Subsequently, all subjects received 150 CS-US pairings. Acquisition of nictitating membrane CRs was retarded relative to a naive control group only in the group that received the preexposures over 10 sessions. Thus, the number of US preexposure sessions, rather than the number of US preexposures, determined whether or not retarded acquisition was observed. In Experiment 2, four groups of rabbits received 1, 5, 20, or 40 shock US preexposures in each of 10 sessions. Over the subsequent 150 CS-US pairings, similar levels of retarded CR acquisition were observed in groups that received 20 and 40 US preexposures per session, a weak retardation effect was observed with 5 preexposures per session, and no retardation was observed with 1 preexposure per session. Thus, Experiment 2 suggested that retarded CR development was not greatly influenced by increasing the number of US preexposures above some minimum threshold number of exposures per session. Implications for current theories were discussed. 相似文献
ABSTRACTThis article explores the application of science identity development theory for women of color interested in the science disciplines; and it advocates for taking an intersectional approach to understanding how women of color form science identities. The article also challenges community college administrators and scholars to focus on redefining science identity development theory within the community college setting as a means to enhance success for women of color pursuing academic work in scientific disciplines. 相似文献

This study addressed whether an application adapted to working with multiple documents implemented in an iPad Pro tablet would promote students’ multiple document comprehension and acceptance of tablets as a multiple document learning tool relative to controls who used a traditional application adapted to sequential reading of single documents. Results indicated that students using the multiple document reading application outperformed the control students in terms of comprehension and also worked more efficiently on the assigned multiple document task, but only if given explicit guidance in selecting, organizing, and integrating information by utilizing the functions of the application. Still, after task completion, the more effective and efficient students guided in using the functions of the multiple document reading application displayed much less acceptance of tablets as a multiple document learning tool than did the control students. We discuss possible explanations for this intriguing performance-acceptance paradox and suggest some avenues for future research in this area.
