Google Scholar,Web of Science,and Scopus: A systematic comparison of citations in 252 subject categories 总被引:1,自引:0,他引:1

Despite citation counts from Google Scholar (GS), Web of Science (WoS), and Scopus being widely consulted by researchers and sometimes used in research evaluations, there is no recent or systematic evidence about the differences between them. In response, this paper investigates 2,448,055 citations to 2299 English-language highly-cited documents from 252 GS subject categories published in 2006, comparing GS, the WoS Core Collection, and Scopus. GS consistently found the largest percentage of citations across all areas (93%–96%), far ahead of Scopus (35%–77%) and WoS (27%–73%). GS found nearly all the WoS (95%) and Scopus (92%) citations. Most citations found only by GS were from non-journal sources (48%–65%), including theses, books, conference papers, and unpublished materials. Many were non-English (19%–38%), and they tended to be much less cited than citing sources that were also in Scopus or WoS. Despite the many unique GS citing sources, Spearman correlations between citation counts in GS and WoS or Scopus are high (0.78-0.99). They are lower in the Humanities, and lower between GS and WoS than between GS and Scopus. The results suggest that in all areas GS citation data is essentially a superset of WoS and Scopus, with substantial extra coverage. 相似文献

In 2015–16 researchers from the University of Melbourne and Museums Victoria undertook a collaborative project which sought to visualise archival data from the museum as a means to investigate the structure and context of the Dorothy Howard Collection. This article introduces Dorothy Howard’s work, which is part of the internationally significant Australian Children’s Folklore Collection, and looks at the project’s processes and outcomes, including the initial visualisations produced. In doing so, the authors highlight the data-intensive nature of such work, suggest the potential of visualisations to reveal collection structures, and outline possibilities for future projects and collaborations. 相似文献

An analysis of 12 semi-structured interviews with university-based scientists and non-scientists illustrates their life journeys towards, or away from, science and the strengths and impact of life occurrences leading them to choose science or non-science professions. We have adopted narrative approaches and used Mezirow's transformative learning theory framework. The areas of discussion from the result have stressed on three main categories that include ‘smooth transition’, ‘incremental wavering transition' and ‘transformative transition’. The article concludes by discussing the key influences that shaped initial attitudes and direction in these people through natural inclination, environmental inspirations and perceptions of science. 相似文献

Professional development for academics in higher education is increasingly important in the United Kingdom and elsewhere. Promoting better teaching practices through professional development is part of the drive for quality and excellence. However, the focus has been on teaching as a "technical" activity, defined as competence in a particular domain of practice. This has obscured the social and discursive practices through which a very particular sort of teacher identity is produced. It is possible, therefore, to examine the ways in which the standards of competence operate to normalise and fashion what it means to be a "good teacher". In this article, we examine extracts from course documentation produced by a UK university through which the professional standards of those working in higher education are being constituted. Our focus is not the quality of these particular materials but the work the documentation performs in building up a particular notion of what characterises a professional teacher in higher education. 相似文献

Postgraduate student teachers’ conceptions of sustainable development were elicited using a questionnaire completed by the entire cohort of geography (N = 21) and science (N = 40) students starting the University of Oxford Post Graduate Certificate in Education (PGCE) secondary course. Responses were analysed in three ways: (i) development of categories to capture features of sustainable development; (ii) scrutiny of individual responses for the presence or absence of key features (specifically environmental, economic and social factors); and (iii) in contrast to these grounded approaches, examination of the responses in light of a pre-specified framework. Notable findings were: (i) the large numbers recognizing the centrality of environmental (87%), economic (69%) and social (49%) factors—about a third highlighted all three factors (the geographers significantly more so than the scientists), while a further third mentioned two of them; (ii) when compared with the pre-specified framework, the aspects of sustainable development largely missing were to do with preservation of diversity, and with uncertainty and precaution in action; (iii) only one response contained an aesthetic element; and (iv) when comparing education for sustainable development with environmental education, the most frequent view identified the former as broader. The findings are related to contemporary literature in the field and some implications for PGCE learning are considered. 相似文献

Various recent politically driven policy interventions have outlined the increased importance of school physical education programmes as a contributor towards realising active lifelong learning targets. This paper explains the origins of the new policy emphasis and describes some of the opportunities which now exist for reviewing many curriculum orientation and fragmentation concerns. However, in reviewing the possibilities for policy aspirations to achieve transformative educational benefits, the paper also outlines how a commitment towards principled progress and educational realignment could founder on the rock of its own ambition unless various critical conceptual questions and associated pedagogical issues are thoroughly addressed. Following analysis of the barriers to progress that exist, the encouraging signs of a more coherent future are discussed. This occurs through analysing the progress of developmental-based programmes, which aim to improve the quality and authenticity of pupils’ learning experiences in physical education, and by analysis of the new professional development opportunities that are available to teachers. 相似文献

The topic of educational alliances undertaken between Sino-foreign universities remains a contentious and much debated matter. This is an area of considerable and often very busy activity with a high rate of failure and frustration—yet, also one of reward, mutual satisfaction, and achievement. This paper evaluates a key aspect of these alliances often overlooked in research: educational delivery activities and projects that form the heart and core of alliances. The paper notes that the development and delivery of a range of programs beyond just degree or part degree courses but of research, seminar, and ancillary activities, lies at the very core of a successful alliances, particularly if these activities can be undertaken in a manner that melds two very different cultural and educational worlds, and in a way that can contribute to the Chinese students' sense of well-being and ability to take part in the globalization of the emerging Chinese market economy. 相似文献

Student science teachers’ conceptions of sustainable development: an empirical study of three postgraduate training cohorts 总被引:1,自引:1,他引:0
Conceptions of sustainable development were elicited using a questionnaire completed by three cohorts of postgraduate students starting a secondary science teacher‐training course (N = 123). Qualitative responses were analysed in three ways: (i) development of categories to capture features of sustainable development; (ii) scrutiny of individual responses for the presence or absence of key features; and (iii) in contrast to these grounded approaches, examination of the responses in light of a framework proposed by the UK Panel for Education for Sustainable Development. Notable findings were: substantial numbers recognised the centrality of environmental (72%), economic (53%) and social (31%) factors—but just 15% highlighted all three; when compared with the pre‐specified framework, the aspects of sustainable development largely missing were to do with citizenship, with preservation of diversity, and with uncertainty and precaution in action. The findings are related to contemporary literature in the field and some implications for trainees’ learning are considered. 相似文献
