This paper defines the metaphor of outsideness in relation to web-based interaction. Outsideness is conceived of as a key influence in online academic conversation. In particular, through the sharing of cultural perspectives, asking questions to resolve doubt, and collaborative writing and re-writing as a basis for shaping ideas through reasoning. An analytical framework is proposed and applied to a case study of an international wiki-based project. Key findings are that there is a tension between participants’ sense of inside and outside influences, resulting in a complex and challenging working environment. Students require support to develop nuanced questioning and conversational skills, including multi-model forms of representation and communication to enhance language skills.  相似文献

The purpose of this study was to examine the relationship between student pre‐performance concerns, student evaluation apprehension, and receiving a grade for a speech. It was hypothesized that in the public speaking course, (a) a positive relationship would exist between student pre‐performance concerns and student evaluation and (b) students who believed their speech was being evaluated for a grade would report a greater amount of pre‐performance concerns than students who believed their speech was not being evaluated for a grade. Both hypotheses were supported. Results are discussed in light of what instructors might do in the classroom to reduce students' pre‐performance concerns.  相似文献

This study compared the quality of child care programs serving children receiving government subsidies to those not serving such children. Thirty-four classrooms in full day programs serving preschool aged children (19 subsidized, 15 unsubsidized) were observed using the Early Childhood Environment Rating Scales-Revised (ECERS-R). (1) Research Findings: One way ANOVA indicated that programs not serving children receiving subsidies were rated higher on overall quality, language and reasoning, learning activities, and social interactions. Teacher salary was significantly correlated with overall quality, and after controlling for teacher salary, subsidy density did not uniquely predict variance in overall quality. (2) Policy Implications: Overall low quality indicates a need for a quality improvement initiative using proven methods. Minimum guidelines for quality beyond state licensing standards should be used to ensure that children in subsidized programs are receiving adequate care and to oversee state and federal investments in early childhood education.  相似文献

A digital disconnect perspective is founded on an assumption that technology use in the home is frequent, creative and generative, and that technology use in the early childhood centre should be the same as that found in the home. However, such arguments divert our attention from understanding the nature of the setting and thereby from an understanding of the role of technologies in education and at home. This study adopts a socio-ecological approach to explore the influence of setting, in particular the elements of activity, time, place and role on young children’s use of digital technologies. It concludes that technology use is characterised by different imperatives in each setting so that thinking about digital differences may be more productive than continuing to focus on the concept of disconnect.  相似文献
