Objective
The purpose of this study was to investigate the relative effectiveness of three web-scale discovery (WSD) tools in answering health sciences search queries.Methods
Simple keyword searches, based on topics from six health sciences disciplines, were run at multiple real-world implementations of EBSCO Discovery Service (EDS), Ex Libris''s Primo, and ProQuest''s Summon. Each WSD tool was evaluated in its ability to retrieve relevant results and in its coverage of MEDLINE content.Results
All WSD tools returned between 50%–60% relevant results. Primo returned a higher number of duplicate results than the other 2 WSD products. Summon results were more relevant when search terms were automatically mapped to controlled vocabulary. EDS indexed the largest number of MEDLINE citations, followed closely by Summon. Additionally, keyword searches in all 3 WSD tools retrieved relevant material that was not found with precision (Medical Subject Headings) searches in MEDLINE.Conclusions
None of the 3 WSD products studied was overwhelmingly more effective in returning relevant results. While difficult to place the figure of 50%–60% relevance in context, it implies a strong likelihood that the average user would be able to find satisfactory sources on the first page of search results using a rudimentary keyword search. The discovery of additional relevant material beyond that retrieved from MEDLINE indicates WSD tools'' value as a supplement to traditional resources for health sciences researchers. 相似文献2.

Internationally, the quality of teachers is a growing focus of educational reform, with new policies attempting to ensure that only the ‘best and brightest’ are selected for the teaching profession. This article tests the assumption underpinning these developments that prospective teachers lack the desired academic and personal qualities. Drawing on data on the career aspirations of 6492 Australian school students in Years 3–12, we investigated who, among these students, expressed interest in teaching and their reasons for doing so. Using logistic regression, we found that interest in teaching was widespread and prior academic achievement was not a significant predictor. Thematic analysis of reasons expressed for interest in teaching indicated that working with children and/or in specific subject areas, altruism, and perceptions of personal suitability for the job dominated student responses. These data provide a counter-narrative to the primacy, in policies for teacher recruitment and selection, of needing to attract ‘better’ students. We argue that policies for improving teacher quality should also capitalise on the widespread interest in teaching among school students. Without such a discursive broadening, we caution that current attempts to attract the ‘best and brightest’ risk undermining the very goals espoused. 相似文献

The title of the 2014 Australian Teacher Education Association (ATEA) conference was Teacher Education, An Audit: Building a platform for future engagement. One of the conference themes was Professional Experience: What works? Why? I seized upon this theme and the title of the conference as it afforded me an opportunity to do an audit of my research in professional experience over the last 25 years. This article presents this evidence base and the messages I have taken from this evidence. I have done this in the hope that, by collating some of the insights gained from the past and the present, it will help to “build a platform for future engagement” in professional experience. In preparing this article I was asked by the Editors to reflect also on how I developed my distinctive line of inquiry and expertise in relation to the practicum across an extended period. These reflections are included. I hope they will support university-based teacher educators in enhancing their satisfaction and achievements from working in this stimulating and provocative field of study. 相似文献

Little is known about how specific iPad applications affect parent–child story‐sharing interactions. This study utilises a case‐study approach to provide an insight into the patterns of interaction, which emerge when a mother and her 33‐month‐old daughter share a self‐created, audio‐visual ‘iPad story’. Multimodal analysis allowed us to gain insights into the complex interaction patterns orchestrated in this new, personalised story‐sharing medium. We found that the app‐mediated story‐sharing context produced a harmonious and smooth interaction, achieving a coherence that is typical of ‘happy’ oral stories. We suggest that the observed interaction resembles that of experiencing a piece of art, and we highlight the need for a holistic approach to understanding the implications for research and practice of children's interactions during multimedia story sharing. 相似文献

Healthcare practitioners have suggested that interpreting person-centered care for people who have dementia to undergraduate students requires guidance in practical application. This article describes the production of a written and digital interdisciplinary educational resource for tertiary students. It uses real-life case scenarios provided by healthcare practitioners to illustrate person-centered care in practice with people who have dementia. The resource provides students with the theoretical underpinning of person-centered care and dementia as well as reflective questions that relate to the reenacted case scenarios to guide their application of this theory in practice. 相似文献

This article explores the dynamics of global campaigns for education through a study of the movement for girls’ and women's education in India since independence in 1947. In particular, it uses the trajectory of ideas within India to theorise about international collaboration on educational goals, with UNESCO and the World Bank being two of the most prominent agencies in the second half of the twentieth century. The article presents an analysis of shifting discourses around women's education at national and international level, along with an exploration of the diverse points of contact between policymakers, activists and academics at both levels. 相似文献
