AIM: In 2002, a discussion in the United Kingdom (UK) between South-west Information for Clinical Effectiveness (SWICE) librarians and a member of the South Australian Department of Human Services Libraries' Consortium (SAHSLC) raised the possibility of developing an after-hours virtual reference service between the two consortium groups. The aim of the service is to put medical practitioners in contact with a librarian when urgent help is required in finding clinical medical information after hours. METHODS: A trial project has begun and has been given the name 'Chasing the Sun'. The service will make use of time-zone differences between the UK and Australia, so that librarians at work in another country will be able to answer urgent patient-related queries that cannot wait until normal office hours. RESULTS: This paper looks at the development of 'Chasing the Sun' from initial concept, funding proposal and trial project stage to implementation. It includes details of the groundwork, software evaluation, trials, outcomes, cost and benefits, future directions and potential problems yet to be experienced or overcome. CONCLUSION: This service is the first of its kind between health libraries in the world and offers potential for future worldwide expansion. 相似文献

Few data exist on gender-typed and gender-segregated play in hunter-gatherer societies, despite their unique demographic and cultural features which may influence children’s gendered play. Using naturalistic observations of Hadza (N = 46, 41% female) and BaYaka (N = 65, 48% female) hunter-gatherer 3- to 18-year-olds from Tanzania and the Republic of Congo, we showed that access to playmates was negatively associated with playing in mixed-gender groups. Young boys did not engage in more rough-and-tumble play than girls, but adolescent boys participated in this type of play more than adolescent girls. Children were also more likely to participate in work-themed play which conformed to gender norms within their society. Findings are discussed within the context of gendered division of labor, child autonomy, and demography. 相似文献

Information about how success and gender affect students' views of ideal and actual classroom role behavior can help both researchers and teachers better understand classroom components such as achievement and curriculum. A 20-item double Q sort was used to measure differences in perceptions of high school science students according to letter grades and gender. Individual Q sort item rankings of 160 students were tested for significant differences according to letter grade received; item ratings were compared according to gender for 215 students. Differences in perception according to success were found for both ideal and actual behavior; 8 and 5 items, respectively, out of each 20-item sort were found to be significant at the p = < 0.05 level. No such overall patterns of difference in view were found between boys and girls, although three ideal student items and one actual self-report item were found to be significantly different at the p = < 0.05 level. 相似文献

This study examines the ways in which preschool teachers support the development of children's explanatory language through science inquiry. Two classrooms in a preschool center using a science inquiry curriculum were videotaped during a 5-week unit on color mixing. Videotapes were analyzed for how teachers facilitated children's explanatory language. An assessment of explanatory language was administered to 47 children in the center before and after the color mixing unit. Analysis of discourse revealed that teachers engaged children as conversational partners and as scientific investigators responsible for their own learning. Explanations were dynamically co-constructed by adults and children within the context of participation in scientific inquiry. By the end of the unit, children produced more on-topic responses, more standard color-mixing terms, and more causal connectives in their responses to the assessment of explanatory language. 相似文献

This study examines how student practice of scientific argumentation using socioscientific bioethics issues affects both teacher expectations of students’ general performance and student confidence in their own work. When teachers use bioethical issues in the classroom students can gain not only biology content knowledge but also important decision-making skills. Learning bioethics through scientific argumentation gives students opportunities to express their ideas, formulate educated opinions and value others’ viewpoints. Research has shown that science teachers’ expectations of student success and knowledge directly influence student achievement and confidence levels. Our study analyzes pre-course and post-course surveys completed by students enrolled in a university level bioethics course (n = 111) and by faculty in the College of Biology and Agriculture faculty (n = 34) based on their perceptions of student confidence. Additionally, student data were collected from classroom observations and interviews. Data analysis showed a disconnect between faculty and students perceptions of confidence for both knowledge and the use of science argumentation. Student reports of their confidence levels regarding various bioethical issues were higher than faculty reports. A further disconnect showed up between students’ preferred learning styles and the general faculty’s common teaching methods; students learned more by practicing scientific argumentation than listening to traditional lectures. Students who completed a bioethics course that included practice in scientific argumentation, significantly increased their confidence levels. This study suggests that professors’ expectations and teaching styles influence student confidence levels in both knowledge and scientific argumentation. 相似文献

AbstractMany approaches to explaining educational inequalities relate explicitly and implicitly to benefits of education, and rational choice theories in particular consider monetary benefits. We specify a concept of the value of education that allows for an empirical analysis of educational benefits, considering both monetary and non-monetary dimensions (instrumental goals) outlined in social production function theory. Our objectives include introducing a sound theoretical framework, the validation of an empirical measurement instrument and an analysis of the differences between certain dimensions of educational values structured by social origin, gender and immigrant background. Analyses are based on a two-wave panel study (SASAL-School Alienation in Switzerland and Luxembourg) carried out in secondary schools in Luxembourg and Switzerland. We distinguish four dimensions within the concept of values of education: stimulation, comfort/status, behavioural confirmation and affection. The different dimensions of the value of education are influenced by gender and immigrant backgrounds in both national settings. 相似文献

This study reports an analysis of how children in a Japanese kindergarten are scaffolded when facing the challenge of collaboratively retelling a kitsune story they have been told. What is referred to as a kitsune story is an example of a trickster tale with foxes as anthropomorphised animals. The participants were ten 5-year-old children and their teacher. Told a story by their teacher, the children were asked later to collaboratively retell it. How this retelling activity is supported – theorised in terms of the metaphor of scaffolding – is analysed on the basis of recordings. The findings show the nature of this evolving process. The conclusion is that the metaphor of scaffolding may require some contextual specification to remain a functional conceptual – and in extension, pedagogical – tool in activities fundamentally different from the activity studied in Wood, Bruner and Ross’ founding 1976 study. 相似文献
